Men with HIV are likely prone to the same cardiovascular risks from testosterone therapy as other men, according to new research.

There’s no reason to think they weren’t, but it hadn’t been demonstrated until now, and men with HIV are already at increased risk for cardiovascular disease. The take-home message is that “it would be prudent for clinicians to monitor closely for cardiovascular risk factors and recommend intervention to lower cardiovascular risk among men with HIV on or considering testosterone therapy,” lead investigator Sabina Haberlen, PhD, an assistant scientist in the infectious disease epidemiology division of Johns Hopkins University, Baltimore, said in a poster that was presented as part of the Conference on Retroviruses & Opportunistic Infections, which was presented online this year. CROI organizers chose to hold a virtual meeting because concerns about the spread of COVID-19.

Testosterone therapy is common among middle-aged and older men with HIV to counter the hypogonadism associated with infection. The investigators turned to the Multicenter AIDS Cohort Study – a 30-year, four-city study of HIV-1 infection in men who have sex with men – to gauge its effect.

The 300 men in the study had a baseline coronary CT angiogram in 2010-2013 and a repeat study a mean of 4.5 years later. They had no history of coronary interventions or kidney dysfunction at baseline and were aged 40-70 years, with a median age of 51 years. About 70% reported never using testosterone, 8% were former users before entering the study, 7% started using testosterone between the two CTs, and 15% entered the study on testosterone and stayed on it.

Adjusting for age, race, cardiovascular risk factors, baseline serum testosterone levels, and other potential confounders, the risk of significant coronary artery calcium (CAC) progression was 2 times greater among continuous users (P = .03) and 2.4 times greater among new users (P = .01), compared with former users, who the investigators used as a control group because, at some point, they too had indications for testosterone replacement and so were more medically similar than never users.

The risk of noncalcified plaque volume progression was also more than twice as high among ongoing users, and elevated, although not significantly so, among ongoing users.

In short, “our findings are similar to those on subclinical atherosclerotic progression” in trials of older men in the general population on testosterone replacement, Dr. Haberlen said.

About half the subjects were white, 41% were at high risk for cardiovascular disease, 91% were on antiretroviral therapy, and 81% had undetectable HIV viral loads. Median total testosterone was 606 ng/dL. CAC progression was defined by incident CAC, at least a 10 Agatston unit/year increase if the baseline CAC score was 1-100, and a 10% or more annual increase if the baseline score was above 100.

Lower baseline serum testosterone was also associated with an increased risk of CAC progression, although not progression of noncalcified plaques.

The work was funded by the National Institutes of Health. Dr. Haberlen didn’t report any relevant disclosures.

Although a 14-day quarantine after exposure to novel coronavirus is “well supported” by evidence, some infected individuals will not become symptomatic until after that period, according to authors of a recent analysis published in Annals of Internal Medicine.

Most individuals infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) will develop symptoms by day 12 of the infection, which is within the 14-day period of active monitoring currently recommended by the Centers for Disease Control and Prevention, the authors wrote.

However, an estimated 101 out of 10,000 cases could become symptomatic after the end of that 14-day monitoring period, they cautioned.

“Our analyses do not preclude that estimate from being higher,” said the investigators, led by Stephen A. Lauer, PhD, MD, of Johns Hopkins Bloomberg School of Public Health, Baltimore.

The analysis, based on 181 confirmed cases of coronavirus disease 2019 (COVID-19) that were documented outside of the outbreak epicenter, Wuhan, China, makes “more conservative assumptions” about the window of symptom onset and potential for continued exposure, compared with analyses in previous studies, the researchers wrote.

The estimated incubation period for SARS-CoV-2 in the 181-patient study was a median of 5.1 days, which is comparable with previous estimates based on COVID-19 cases outside of Wuhan and consistent with other known human coronavirus diseases, such as SARS, which had a reported mean incubation period of 5 days, Dr. Lauer and colleagues noted.

Symptoms developed within 11.5 days for 97.5% of patients in the study.

Whether it’s acceptable to have 101 out of 10,000 cases becoming symptomatic beyond the recommended quarantine window depends on two factors, according to the authors. The first is the expected infection risk in the population that is being monitored, and the second is “judgment about the cost of missing cases,” wrote the authors.

In an interview, Aaron Eli Glatt, MD, chair of medicine at Mount Sinai South Nassau, Oceanside, N.Y., said that in practical terms, the results suggest that the majority of patients with COVID-19 will be identified within 14 days, with an “outside chance” of an infected individual leaving quarantine and transmitting virus for a short period of time before becoming symptomatic.

“I think the proper message to give those patients [who are asymptomatic upon leaving quarantine] is, ‘after 14 days, we’re pretty sure you’re out of the woods, but should you get any symptoms, immediately requarantine yourself and seek medical care,” he said.

Study coauthor Kyra H. Grantz, a doctoral graduate student at the Johns Hopkins Bloomberg School of Public Health, said that extending a quarantine beyond 14 days might be considered in the highest-risk scenarios, though the benefits of doing so would have to be weighed against the costs to public health and to the individuals under quarantine.

“Our estimate of the incubation period definitely supports the 14-day recommendation that the CDC has been using,” she said in an interview.

Dr. Grantz emphasized that the estimate of 101 out of 10,000 cases developing symptoms after day 14 of active monitoring – representing the 99th percentile of cases – assumes the “most conservative, worst-case scenario” in a population that is fully infected.

“If you’re looking at a following a cohort of 1,000 people whom you think may have been exposed, only a certain percentage will be infected, and only a certain percentage of those will even develop symptoms – before we get to this idea of how many people would we miss,” she said.

The study was supported by the Centers for Disease Control and Prevention, the National Institute of Allergy and Infectious Diseases, the National Institute of General Medical Sciences, and the Alexander von Humboldt Foundation. Four authors reported disclosures related to those entities, and the remaining five reported no conflicts of interest.

A 17% surge in mortality from fall-related traumatic brain injuries from 2008 to 2017 was driven largely by increases among those aged 75 years and older, according to investigators from the Centers for Disease Control and Prevention.

Nationally, the rate of deaths from traumatic brain injuries (TBIs) caused by unintentional falls rose from 3.86 per 100,000 population in 2008 to 4.52 per 100,000 in 2017, as the number of deaths went from 12,311 to 17,408, said Alexis B. Peterson, PhD, and Scott R. Kegler, PhD, of the CDC’s National Center for Injury Prevention and Control in Atlanta.

“This increase might be explained by longer survival following the onset of common diseases such as stroke, cancer, and heart disease or be attributable to the increasing population of older adults in the United States,” they suggested in the Mortality and Morbidity Weekly Report.

The rate of fall-related TBI among Americans aged 75 years and older increased by an average of 2.6% per year from 2008 to 2017, compared with 1.8% in those aged 55-74. Over that same time, death rates dropped for those aged 35-44 (–0.3%), 18-34 (–1.1%), and 0-17 (–4.3%), they said, based on data from the National Vital Statistics System’s multiple cause-of-death database.

The death rate increased fastest in residents of rural areas (2.9% per year), but deaths from fall-related TBI were up at all levels of urbanization. The largest central cities and fringe metro areas were up by 1.4% a year, with larger annual increases seen in medium-size cities (2.1%), small cities (2.2%), and small towns (2.1%), Dr. Peterson and Dr. Kegler said.

Rates of TBI-related mortality in general are higher in rural areas, they noted, and “heterogeneity in the availability and accessibility of resources (e.g., access to high-level trauma centers and rehabilitative services) can result in disparities in postinjury outcomes.”

State-specific rates increased in 45 states, although Alaska was excluded from the analysis because of its small number of cases (less than 20). Increases were significant in 29 states, but none of the changes were significant in the 4 states with lower rates at the end of the study period, the investigators reported.

“In older adults, evidence-based fall prevention strategies can prevent falls and avert costly medical expenditures,” Dr. Peterson and Dr. Kegler said, suggesting that health care providers “consider prescribing exercises that incorporate balance, strength and gait activities, such as tai chi, and reviewing and managing medications linked to falls.”

LOS ANGELES – The edge that the direct-acting oral anticoagulant apixaban (Eliquis) has over warfarin for safely preventing ischemic events in patients with atrial fibrillation and either a recent acute coronary syndrome event or a recent percutaneous coronary intervention held up even in patients with a history of stroke, transient ischemic attack, or thromboembolic event, according to a prespecified secondary analysis of data collected in the AUGUSTUS trial.

Mitchel L. Zoler/MDedge News

The treatment advantages of apixaban, compared with warfarin, seen in the overall AUGUSTUS results, first reported in March 2019, “were consistent” with the benefits seen in the subgroup of enrolled patients with a prior stroke, transient ischemic attack (TIA), or thromboembolic (TE) event, M. Cecilia Bahit, MD, said at the International Stroke Conference sponsored by the American Heart Association.

All patients in AUGUSTUS received a P2Y12 inhibitor antiplatelet drug, which was clopidogrel for more than 90% of patients. The two-by-two factorial design of AUGUSTUS also assessed the safety and efficacy of either adding or withholding aspirin from the two-drug regimen that all patients in the study received with a P2Y12 inhibitor plus an anticoagulant (apixaban or warfarin). The most notable finding of the aspirin versus placebo analysis was that patients without a prior stroke, TIA, or TE event had a “more profound” increase in their rate of major or clinically relevant minor bleeds when also treated with aspirin, compared with patients who received aspirin and had a history of stroke, TIA, or TE event, reported Dr. Bahit, a chief of cardiology and director of clinical research at the INECO Foundation in Rosario, Argentina.

In general, the findings of the secondary analysis that took into account stroke, TIA, or TE history “confirmed” the main AUGUSTUS findings, Dr. Bahit said; an antithrombotic regimen of apixaban plus clopidogrel (or other P2Y12 inhibitor) without aspirin was superior for both efficacy and safety, compared with the alternative regimens that either substituted warfarin for apixaban or that added aspirin.

AUGUSTUS enrolled 4,614 atrial fibrillation (AFib) patients who either had a recent acute coronary syndrome (ACS) event or had recently undergone percutaneous coronary intervention (PCI) at any of 492 sites in 33 countries during 2015-2018. The study’s primary endpoint was the incidence of major or clinically relevant minor bleeds after 6 months, which was significantly lower in the subgroups that received apixaban instead of warfarin and in patients who received placebo instead of aspirin. The secondary endpoint of death or hospitalization after 6 months was also significantly lower in the apixaban-treated patients, compared with those on warfarin, while the aspirin and placebo subgroups showed no difference in the incidence of these events (N Engl J Med. 2019 Apr 18;380[16]:1509-24).

The results reported by Dr. Bahit also highlighted both the high risk faced by patients with AFib who also have had an ACS event or PCI, as well as a prior stroke, TIA, or TE event, noted Larry B. Goldstein, MD, professor and chairman of neurology at the University of Kentucky, Lexington. “It’s difficult, because these patients had an ACS event or PCI, and you don’t want a coronary too close up, but do these patients really need a P2Y12 inhibitor plus an anticoagulant? Could these patients do as well on apixaban only? I would have liked to see that treatment arm in the study,” Dr. Goldstein commented in an interview.

“These are challenging patients because they often require anticoagulation for the AFib as well as antiplatelet agents” for the recent PCI or ACS event, commented Mitchell S.V. Elkind, MD, professor of neurology at Columbia University, New York. “The question has always been: How many blood thinners should these patients be on? Potentially they could be on three different agents [an anticoagulant and two antiplatelet drugs], and we know that all of those drugs together pretty dramatically increase the risk of bleeding. About 15% of the patients in the overall AUGUSTUS trial had either cerebrovascular disease or systemic thromboembolism, so this was a small subgroup of the overall trial, but the overall trial was large so it’s a significant number of patients who met this criteria. The results confirmed that even in a group of patients who may be considered at high risk because they have a prior history of cerebrovascular disease use of apixaban instead of warfarin seemed safer, and that those patients did not need to be on aspirin as well as their other antiplatelet agent. Patients with a history of stroke, in fact, had a lower risk of bleeding than the other patients in this trial, so one could argue that they should be on an agent like apixaban as well as an antiplatelet agent like clopidogrel without addition of aspirin,” he said in a recorded statement.

In addition to implications for using prescription drugs like apixaban and clopidogrel, the findings also send a message about the need for very aggressive implementation of lifestyle measures that can reduce cardiovascular disease risk in these patients, added Dr. Goldstein. The AUGUSTUS outcome analyses that subdivided the study population into those with a prior stroke, TIA, or TE event – 633 patients or about 14% of the 4,581 patients eligible for this analysis – and those who did not have this history showed the extremely high, incrementally elevated risk faced by patients with these prior events.

A history of stroke, TIA, or TE event linked with a jump in the 90-day rate of major or clinically relevant minor bleeds from 13% without this history to 17%, which is a 31% relative increase; it boosted the 90-day rate of death or hospitalization from 25% to 31%, a 24% relative increase; and it jacked up the rate of death or ischemic events from 6% to 9%, a 50% relative increase, Dr. Bahit reported.

These substantial increases “suggest we need to be very aggressive” in managing these high-risk patients who combine a background of AFib, a prior stroke, TIA, or TE events, and a recent ACS event or PCI, Dr. Goldstein observed. In these patients, he suggested that clinicians make sure to address smoking cessation, obesity, exercise, diet, and statin use, and get each of these to an optimal level to further cut risk. If all five of these basic interventions were successfully administered to a patient they could collectively cut the patient’s event risk by about 80%, he added.

AUGUSTUS was funded by Bristol-Myers Squibb and Pfizer, the companies that jointly market apixaban. Dr. Bahit has received honoraria from Pfizer, and from CSL Behring and Merck. Dr. Elkind and Dr. Goldstein had no relevant disclosures.

LOS ANGELES – The edge that the direct-acting oral anticoagulant apixaban (Eliquis) has over warfarin for safely preventing ischemic events in patients with atrial fibrillation and either a recent acute coronary syndrome event or a recent percutaneous coronary intervention held up even in patients with a history of stroke, transient ischemic attack, or thromboembolic event, according to a prespecified secondary analysis of data collected in the AUGUSTUS trial.

The treatment advantages of apixaban, compared with warfarin, seen in the overall AUGUSTUS results, first reported in March 2019, “were consistent” with the benefits seen in the subgroup of enrolled patients with a prior stroke, transient ischemic attack (TIA), or thromboembolic (TE) event, M. Cecilia Bahit, MD, said at the International Stroke Conference sponsored by the American Heart Association.

All patients in AUGUSTUS received a P2Y12 inhibitor antiplatelet drug, which was clopidogrel for more than 90% of patients. The two-by-two factorial design of AUGUSTUS also assessed the safety and efficacy of either adding or withholding aspirin from the two-drug regimen that all patients in the study received with a P2Y12 inhibitor plus an anticoagulant (apixaban or warfarin). The most notable finding of the aspirin versus placebo analysis was that patients without a prior stroke, TIA, or TE event had a “more profound” increase in their rate of major or clinically relevant minor bleeds when also treated with aspirin, compared with patients who received aspirin and had a history of stroke, TIA, or TE event, reported Dr. Bahit, a chief of cardiology and director of clinical research at the INECO Foundation in Rosario, Argentina.

In general, the findings of the secondary analysis that took into account stroke, TIA, or TE history “confirmed” the main AUGUSTUS findings, Dr. Bahit said; an antithrombotic regimen of apixaban plus clopidogrel (or other P2Y12 inhibitor) without aspirin was superior for both efficacy and safety, compared with the alternative regimens that either substituted warfarin for apixaban or that added aspirin.

AUGUSTUS enrolled 4,614 atrial fibrillation (AFib) patients who either had a recent acute coronary syndrome (ACS) event or had recently undergone percutaneous coronary intervention (PCI) at any of 492 sites in 33 countries during 2015-2018. The study’s primary endpoint was the incidence of major or clinically relevant minor bleeds after 6 months, which was significantly lower in the subgroups that received apixaban instead of warfarin and in patients who received placebo instead of aspirin. The secondary endpoint of death or hospitalization after 6 months was also significantly lower in the apixaban-treated patients, compared with those on warfarin, while the aspirin and placebo subgroups showed no difference in the incidence of these events (N Engl J Med. 2019 Apr 18;380[16]:1509-24).

The results reported by Dr. Bahit also highlighted both the high risk faced by patients with AFib who also have had an ACS event or PCI, as well as a prior stroke, TIA, or TE event, noted Larry B. Goldstein, MD, professor and chairman of neurology at the University of Kentucky, Lexington. “It’s difficult, because these patients had an ACS event or PCI, and you don’t want a coronary too close up, but do these patients really need a P2Y12 inhibitor plus an anticoagulant? Could these patients do as well on apixaban only? I would have liked to see that treatment arm in the study,” Dr. Goldstein commented in an interview.

“These are challenging patients because they often require anticoagulation for the AFib as well as antiplatelet agents” for the recent PCI or ACS event, commented Mitchell S.V. Elkind, MD, professor of neurology at Columbia University, New York. “The question has always been: How many blood thinners should these patients be on? Potentially they could be on three different agents [an anticoagulant and two antiplatelet drugs], and we know that all of those drugs together pretty dramatically increase the risk of bleeding. About 15% of the patients in the overall AUGUSTUS trial had either cerebrovascular disease or systemic thromboembolism, so this was a small subgroup of the overall trial, but the overall trial was large so it’s a significant number of patients who met this criteria.

Nationwide influenza activity declined for the third consecutive week, but the 2019-2020 season is on pace to be the longest in more than a decade.

Outpatient visits to health care providers for influenza-like illness dropped from 5.5% the previous week to 5.3% of all visits for the week ending Feb. 29, the Centers for Disease Control and Prevention said on March 6.

The national baseline rate of 2.4% was first reached during the week of Nov. 9, 2019 – marking the start of flu season – and has remained at or above that level for 17 consecutive weeks. Last year’s season, which also was the longest in a decade, lasted 21 consecutive weeks but started 2 weeks later than the current season and had a lower outpatient-visit rate (4.5%) for the last week of February, CDC data show.

This season’s earlier start could mean that even a somewhat steep decline in visits to below the baseline rate – marking the end of the season – might take 5 or 6 weeks and would make 2019-2020 even longer than 2018-2019.

The activity situation on the state level reflects the small national decline. For the week ending Feb. 29, there were 33 states at level 10 on the CDC’s 1-10 activity scale, compared with 37 the week before, and a total of 40 in the “high” range of 8-10, compared with 43 the week before, the CDC’s influenza division reported.

The other main measure of influenza activity, percentage of respiratory specimens testing positive, also declined for the third week in a row and is now at 24.3% after reaching a high of 30.3% during the week of Feb. 2-8, the influenza division said.

The overall cumulative hospitalization rate continues to remain at a fairly typical 57.9 per 100,000 population, but rates for school-aged children (84.9 per 100,000) and young adults (31.2 per 100,000) are among the highest ever recorded at this point in the season. Mortality among children – now at 136 for 2019-2020 – is higher than for any season since reporting began in 2004, with the exception of the 2009 pandemic, the CDC said.

The toilet bowl, sink, and bathroom door handle of an isolation room housing a patient with the novel coronavirus tested positive for the virus, raising the possibility that viral shedding in the stool could represent another route of transmission, investigators reported.

CDC/ Dr. Fred Murphy; Sylvia Whitfield

Air outlet fans and other room sites also tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), though an anteroom, a corridor, and most personal protective equipment (PPE) worn by health care providers tested negative, according to the researchers, led by Sean Wei Xiang Ong, MBBS, of the National Centre for Infectious Diseases, Singapore.

Taken together, these findings suggest a “need for strict adherence to environmental and hand hygiene” to combat significant environmental contamination through respiratory droplets and fecal shedding, Dr. Ong and colleagues wrote in JAMA.

Aaron Eli Glatt, MD, chair of medicine at Mount Sinai South Nassau in New York, said these results demonstrate that SARS-CoV-2 is “clearly capable” of contaminating bathroom sinks and toilets.

“That wouldn’t have been the first place I would have thought of, before this study,” he said in an interview. “You need to pay attention to cleaning the bathrooms, which we obviously do, but that’s an important reminder.”

The report by Dr. Ong and coauthors included a total of three patients housed in airborne infection isolation rooms in a dedicated SARS-CoV-2 outbreak center in Singapore. For each patient, surface samples were taken from 26 sites in the isolation room, an anteroom, and a bathroom. Samples were also taken from PPE on physicians as they left the patient rooms.

Samples for the first patient, taken right after routine cleaning, were all negative, according to researchers. That room was sampled twice, on days 4 and 10 of the illness, while the patient was still symptomatic. Likewise, for the second patient, postcleaning samples were negative; those samples were taken 2 days after cleaning.

However, for the third patient, samples were taken before routine cleaning. In this case, Dr. Ong and colleagues said 13 of 15 room sites (87%) were positive, including air outlet fans, while 3 of 5 toilet sites (60%) were positive as well, though no contamination was found in the anteroom, corridor, or in air samples.

That patient had two stool samples that were positive for SARS-CoV-2, but no diarrhea, authors said, and had upper respiratory tract involvement without pneumonia.

The fact that swabs of the air exhaust outlets tested positive suggests that virus-laden droplets could be “displaced by airflows” and end up on vents or other equipment, Dr. Ong and coauthors reported.

All PPE samples tested negative, except for the front of one shoe.

“The risk of transmission from contaminated footwear is likely low, as evidenced by negative results in the anteroom and corridor,” they wrote.

While this study included only a small number of patients, Dr. Glatt said the findings represent an important and useful contribution to the literature on coronavirus disease 2019 (COVID-19).

“Every day we’re getting more information, and each little piece of the puzzle helps us in the overall management of individuals with COVID-19,” he said in the interview. “They’re adding to our ability to manage, control, and mitigate further spread of the disease.”

Funding for the study came from the National Medical Research Council in Singapore and DSO National Laboratories. Dr. Ong and colleagues reported no conflicts of interest.

A team of researchers has discovered important commonalities between SARS-CoV-2 and SARS-CoV infection that could lead to a potential targets for antiviral intervention.

Markus Hoffmann, of the Leibniz Institute for Primate Research, Göttingen, Germany, and a team of investigators also found that antibody responses raised against SARS-S during infection or vaccination might offer some level of protection against SARS-CoV-2 infection. Their findings were published in Cell.

In order for coronaviruses to enter a cell, they must first bind their viral spike (S) proteins to cellular receptors and depend on S protein priming by host cell proteases. The study found that the SARS-CoV-2, causal agent for COVID-19, uses the same SARS-CoV receptor, ACE2, for entry and uses the serine protease TMPRSS2 for S protein priming as the original SARS-CoV-1 (SARS). Importantly, the researchers also found that the cellular serine protease TMPRSS2 primes SARS-CoV-2-S for entry and that a serine protease inhibitor blocks SARS-CoV-2 infection of lung cells, providing opportunities for potential therapeutic intervention.

The researchers performed a sequence analysis that showed SARS-CoV-2 clusters with SARS-CoV–related viruses from bats, of which some – but not all – can use ACE2 for host cell entry. Further analysis of the receptor binding motif known to make contact with ACE2 showed that most amino acid residues essential for ACE2 binding by SARS-S were conserved in SARS-2-S but were absent from S proteins of those SARS-related coronaviruses previously found not to use ACE2.

In addition, the researchers found that SARS-CoV-2–infected BHK-21 cells transfected to express ACE2 with high efficiency, but not the parental BHK-21 cells indicating that SARS-CoV-2-S, like the original SARS virus S protein, uses ACE2 for cellular entry.

Using cultured cells, the researchers found that the protease inhibitor, camostat mesylate, inhibited SARS-S and SARS-2-S entry into primary human lung cells, demonstrating that SARS-CoV-2 can use TMPRSS2 for S protein priming and that camostat mesylate can block SARS-CoV-2 infection of lung cells. Camostat mesylate has been used as a therapy for some forms of cancer and other viral infections.

In addition to their research on the protease inhibitor, the researchers also found that sera from convalescent SARS patients cross-neutralized SARS-2-S–driven entry. They found that four sera obtained from three convalescent SARS patients inhibited SARS-S entry into cell lines in a concentration dependent fashion.

“We demonstrate that SARS-CoV-2 uses the SARS55 CoV receptor, ACE2, for entry and the serine protease TMPRSS2 for S protein priming. A TMPRSS2 inhibitor approved for clinical use blocked entry and might constitute a treatment option. Finally, we show that the sera from convalescent SARS patients cross-neutralized SARS-2-S–driven entry,” the authors concluded.

The study was supported by BMBF (RAPID Consortium) and German Research Foundation (DFG). The authors reported that they had no conflicts.

Hospital-related infections have been widely reported during the ongoing coronavirus outbreak, with healthcare professionals bearing a disproportionate risk. However, a proactive response in Hong Kong’s public hospital system appears to have bucked this trend and successfully protected both patients and staff from SARS-CoV-2, according to a study published online today in Infection Control & Hospital Epidemiology.

During the first 42 days of the outbreak, the 43 hospitals in the network tested 1275 suspected cases and treated 42 patients with confirmed COVID-19, the disease caused by SARS-CoV-2 infection. Yet, there were no nosocomial infections or infections among healthcare personnel, report Vincent C.C. Cheng, MD, FRCPath, the hospital’s infection control officer, and colleagues.

Cheng and colleagues note that 11 out of 413 healthcare workers who treat patients with confirmed infections had unprotected exposure and were in quarantine for 14 days, but none became ill.

In comparison, they note, the 2003 SARS outbreak saw almost 60% of nosocomial cases occurring in healthcare workers.

Proactive bundle

The Hong Kong success story may be due to a stepped-up proactive bundle of measures that included enhanced laboratory surveillance, early airborne infection isolation, and rapid-turnaround molecular diagnostics. Other strategies included staff forums and one-on-one discussions about infection control, employee training in protective equipment use, hand-hygiene compliance enforcement, and contact tracing for workers with unprotected exposure.

In addition, surgical masks were provided for all healthcare workers, patients, and visitors to clinical areas, a practice previously associated with reduced in-hospital transmission during influenza outbreaks, the authors note.

Hospitals also mandated use of personal protective equipment (PPE) for aerosol-generating procedures (AGPs), such as endotracheal intubation, open suctioning, and high-flow oxygen use, as AGPs had been linked to nosocomial transmission to healthcare workers during the 2003 SARS outbreak.

The infection control measures, which were part of a preparedness plan developed after the SARS outbreak, were initiated on December 31, when the first reports of a cluster of infections came from Wuhan, China.

As the outbreak evolved, the Hong Kong hospitals quickly widened the epidemiologic criteria for screening, from initially including only those who had been to a wet market in Wuhan within 14 days of symptom onset, to eventually including anyone who had been to Hubei province, been in a medical facility in mainland China, or in contact with a known case.  

All suspected cases were sent to an airborne-infection isolation room (AIIR) or a ward with at least a meter of space between patients.

“Appropriate hospital infection control measures could prevent nosocomial transmission of SARS-CoV-2,” the authors write. “Vigilance in hand hygiene practice, wearing of surgical mask in the hospital, and appropriate use of PPE in patient care, especially [when] performing AGPs, are the key infection control measures to prevent nosocomial transmission of SARS-CoV-2 even before the availability of effective antiviral agents and vaccine.”

Asked for his perspective on the report, Aaron E. Glatt, MD, chairman of the department of medicine and chief of infectious diseases at Mount Sinai South Nassau in Oceanside, New York, said that apart from the widespread issuing of surgical masks to workers, patients, and visitors, the measures taken in Hong Kong are not different from standard infection-control practices in American hospitals. Glatt, who is also a hospital epidemiologist, said it was unclear how much impact the masks would have.

“Although the infection control was impressive, I don’t see any evidence of a difference in care,” he told Medscape Medical News.

Could zero infection transmission be achieved in the more far-flung and variable settings of hospitals across the United States? “The ability to get zero transmission is only possible if people adhere to the strictest infection-control guidelines,” Glatt said. “That is clearly the goal, and it will take time to see if our existing strict guidelines are sufficient to maintain zero or close to zero contamination and transmission rates in our hospitals.”

Rather than looking to change US practices, he stressed adherence to widely established tenets of care. “It’s critically important to keep paying close attention to the basics, to the simple blocking and tackling, and to identify which patients are at risk, and therefore, when workers need protective equipment,” he said.

“Follow the recommended standards,” continued Glatt, who is also a spokesperson for the Infectious Diseases Society of America and did not participate in this study.

In a finding from an ancillary pilot experiment, the Hong Kong researchers found exhaled air from a patient with a moderate coronavirus load showed no evidence of the virus, whether the patient was breathing normally or heavily, speaking, or coughing. And spot tests around the room detected the virus in just one location.

“We may not be able to make a definite conclusion based on the analysis of a single patient,” the authors write. “However, it may help to reassure our staff that the exhaled air may be rapidly diluted inside the AIIR with 12 air changes per hour, or probably the SARS-CoV-2 may not be predominantly transmitted by [the] airborne route.”

However, a recent Singapore study showed widespread environmental contamination by SARS-CoV-2 through respiratory droplets and fecal shedding, underlining the need for strict adherence to environmental and hand hygiene. Post-cleaning samples tested negative, suggesting that standard decontamination practices are effective. 

This work was partly supported by the Consultancy Service for Enhancing Laboratory Surveillance of Emerging Infectious Diseases of the Department of Health, Hong Kong Special Administrative Region; and the Collaborative Innovation Center for Diagnosis and Treatment of Infectious Diseases, Ministry of Education of China. The authors and Glatt have disclosed no relevant financial relationships.

The Centers for Medicare & Medicaid Services issued two guidance documents related to helping contain the spread of the coronavirus, primarily aimed at ensuring that health care providers are implementing proper infection control procedures.

The first guidance document, “Guidance for Infection Control and Prevention Concerning Coronavirus Disease (COVID-19): FAQs and Considerations for Patient Triage, Placement and Hospital Discharge,” issued March 4, provides some basic guidance, including identifying which patients are at risk, how facilities should screen for COVID-19, how facilities should monitor or restrict health care facility staff, and other recommendations for infection prevention and control.

“Hospitals should identify visitors and patients at risk for having COVID-19 infection before or immediately upon arrival to the healthcare facility,” the guidance document notes. “For patients, implement respiratory hygiene and cough etiquette (i.e., placing a face mask over the patient’s nose and mouth if that has not already been done) and isolate the patient in an examination room with the door closed. If the patient cannot be immediately moved to an examination room, ensure they are not allowed to wait among other patients seeking care.”

The document offers further information regarding the care of patients and provides numerous links to existing guidance from the Centers for Disease Control and Prevention.

The second document, “Guidance for Infection Control and Prevention of Coronavirus Disease 2019 (COVID-19) in Nursing Homes,” issued the same day, provides information on how to limit and monitor visitors as well as monitor and restrict health staff. It details when to transfer residents with suspected or confirmed coronavirus infection, and when a nursing home should accept a resident diagnosed with COVID-19.

Facilities “should contact their local health department if they have questions or suspect a resident of a nursing home has COVID-19,” the document states. “Per CDC, prompt detection, triage and isolation of potentially infectious patients are essential to prevent unnecessary exposure among patients, healthcare personnel, and visitors at the facility.”

The CMS also announced that it is suspending all nonemergency survey activity.

“CMS is suspending nonemergency inspections across the country, allowing inspectors to turn their focus on the most serious health and safety threats like infectious diseases and abuse,” the agency stated in a March 4 memo. “This shift in approach will also allow inspectors to focus on addressing the spread of ... COVID-19. CMS is issuing this memorandum to State Survey Agencies to provide important guidelines for the inspection process in situations in which a COVID-19 is suspected.”

In a statement, CMS Administrator Seema Verma said these actions “represent a call to action across the health care system. All health care providers must immediately review their procedures to ensure compliance with CMS’ infection control requirements, as well as the guidelines from the Centers for Disease Control and Prevention.”

When physicians gaze into their crystal balls to predict what’s coming in 2020, they see continued efforts to defund the Affordable Care Act – meaning the ACA will still be around to be defunded – but they don’t see a lot of support for universal health care, according to health care market research company InCrowd.

Expectations for universal health care came in at 18% of the 100 generalists and 101 specialists who responded to InCrowd’s fifth annual health care predictions survey, which left 82% who thought that “election outcomes will result in universal healthcare support” was somewhat or very unlikely in 2020.

One respondent, a specialist from California, commented that “the global data on universal healthcare for all shows that it results in overall improved population health. Unfortunately, we are so polarized in the US against universal healthcare driven by bias from health insurance companies and decision makers that are quick to ignore scientific data.”

This was the first time InCrowd asked physicians about universal health care, but ACA-related predictions have been included before, and all three scenarios presented were deemed to be increasingly likely, compared with 2019.

Respondents thought that federal government defunding was more likely to occur in 2020 (80%) than in 2019 (73%), but increased majorities also said that preexisting conditions coverage would continue (78% in 2020 vs. 70% in 2019) and that the ACA would remain in place (74% in 2020 vs. 60% in 2019), InCrowd reported after the survey, which was conducted from Dec. 30, 2019, to Jan. 2, 2020.

A respondent who thought the ACA will be eliminated said, “I have as many uninsured today as before the ACA. They are just different. Mainly younger patients who spend less in a year on healthcare than one month’s premium.” Another suggested that eliminateing it “will limit access to care and overload [emergency departments]. More people will die.”

Cost was addressed in a separate survey question that asked how physicians could help to reduce health care spending in 2020.

The leading answer, given by 37% of respondents, was for physicians to “inform themselves of costs and adapt cost-saving prescription practices.” Next came “limit use of expensive tests and scans” with 21%, followed by “prescribe generics when possible” at 20%, which was a substantial drop from the 38% it garnered in 2019, InCrowd noted.

“Participation in [shared savings] programs and risk-based incentive programs and pay-for-performance programs” would provide “better stewardship of resources,” a primary care physician from Michigan wrote.

When the survey turned to pharmaceutical industry predictions for 2020, cost was the major issue.

“What’s interesting about this year’s data is that we’re seeing less emphasis on the importance of bringing innovative, new therapies to market faster … versus expanding affordability, which was nearly a unanimous top priority for respondents,” Daniel S. Fitzgerald, InCrowd’s CEO and president, said in a separate statement.

When physicians gaze into their crystal balls to predict what’s coming in 2020, they see continued efforts to defund the Affordable Care Act – meaning the ACA will still be around to be defunded – but they don’t see a lot of support for universal health care, according to health care market research company InCrowd.

Expectations for universal health care came in at 18% of the 100 generalists and 101 specialists who responded to InCrowd’s fifth annual health care predictions survey, which left 82% who thought that “election outcomes will result in universal healthcare support” was somewhat or very unlikely in 2020.

One respondent, a specialist from California, commented that “the global data on universal healthcare for all shows that it results in overall improved population health. Unfortunately, we are so polarized in the US against universal healthcare driven by bias from health insurance companies and decision makers that are quick to ignore scientific data.”
