Wuhan coronavirus cluster suggests human-to-human spread

Article Type
Changed

A Chinese man became ill from a novel coronavirus (2019-nCoV) 4 days after arriving in Vietnam to visit his 27-year-old son. Three days later the healthy young man was also stricken, according to a report published online Jan. 28 in the New England Journal of Medicine.

“This family cluster of 2019-nCoV infection that occurred outside China arouses concern regarding human-to-human transmission,” the authors wrote.

The father, age 65 years and with multiple comorbidities including hypertension, type 2 diabetes, coronary heart disease with stent placement, and lung cancer, flew to Hanoi with his wife on January 13; they traveled from the Wuchang district in Wuhan, China, where outbreaks of 2019-nCoV have been occurring.

On Jan. 17, the older man and his wife met their adult son in Ho Chi Minh City, Vietnam, and shared a hotel room with him for 3 days. The father developed a fever that same day and the son developed a dry cough, fever, diarrhea, and vomiting on Jan. 20. Both men went to a hospital ED on Jan. 22.

The authors say the timing of the son’s symptoms suggests the incubation period may have been 3 days or fewer.

Upon admission to the hospital, the father reported that he had not visited a “wet market” where live and dead animals are sold while he was in Wuhan. Throat swabs were positive for 2019-nCoV on real-time reverse-transcription–polymerase-chain-reaction assays.

The man was placed in isolation and “treated empirically with antiviral agents, broad-spectrum antibiotics, and supportive therapies,” wrote Lan T. Phan, PhD, from the Pasteur Institute Ho Chi Minh City and coauthors.

On admission, chest radiographs revealed an infiltrate in the upper lobe of his left lung; he developed worsening dyspnea with hypoxemia on Jan. 25 and required supplemental oxygen at 5 L/min by nasal cannula. Chest radiographs showed a progressive infiltrate and consolidation. His fever resolved on that day and he has progressively improved.

The man’s son had a fever of 39° C (102.2° F) when the two men arrived at the hospital on Jan. 22; hospital staff isolated the son, and chest radiographs and other laboratory tests were normal with the exception of an increased C-reactive protein level.

The son’s throat swab was positive for 2019-nCoV and he is believed to have been exposed from his father; however, the strains have not been ascertained.

“This family had traveled to four cities across Vietnam using various forms of transportation, including planes, trains, and taxis,” the authors wrote. A total of 28 close contacts were identified, none of whom have developed respiratory symptoms. The older man’s wife has been healthy as well.

The authors have disclosed no relevant financial relationships.

HHS: Coronavirus risk low in U.S., vaccine development underway

Article Type
Changed

U.S. public health officials attempted to stymie concerns about the coronavirus during a press conference on Tuesday, emphasizing that most Americans are not in danger of contracting the illness and urging citizens not to take extreme measures in response to the low-risk virus.

“Right now, there is no spread of this virus in our communities here at home,” Centers for Disease Control and Prevention director Robert Redfield, MD, said during the Jan. 28 press conference. “This is why our current assessment is that the immediate health risk of this new virus to the general public is low in our nation. The coming days and weeks are likely to bring more confirmed cases here and around the world, including the possibility of some person-to-person spreading, but our goal of the ongoing U.S. public health response is to contain this outbreak and prevent sustained spread of the virus in our country.”

During the press conference, Department Health & Human Services Secretary Alex M. Azar II, reiterated there have been only five confirmed U.S. cases of the coronavirus thus far and all were associated with travel to Wuhan, China, where the virus first appeared. The number of confirmed cases in China, meanwhile, has risen to more than 4,500 with about 100 associated deaths.

U.S. health providers should be on the lookout for any patient who has traveled to China recently, particularly to Hubei province, and they should pay close attention to any relevant symptoms, Secretary Azar said during the press conference.

He defended the decision not to declare a public health emergency at this time, stressing that such a move is based on standards and requirements not yet met by the coronavirus.

“It’s important to remember where we are right now; we have five cases in the United States, each of those individuals with direct contact to Wuhan and no person-to-person transmission in the United States,” Secretary Azar said. “I won’t hesitate at all to invoke any authorities that I need to ensure that we’re taking all the steps to protect the American people, but I’ll do it when it’s appropriate under the standards that we have and the authorities that I need.”

In the meantime, a number of efforts are underway by U.S. agencies to assess the nation’s emergency preparedness stockpile, to assist American families in China with evacuation, and to pursue research into diagnostics and a potential vaccine for the virus, Secretary Azar said.

With regard to countermeasures, the CDC has rapidly developed a diagnostic based on the published sequence of the virus, said Anthony Fauci, MD, director for the National Institute of Allergy and Infectious Diseases (NIAID). The National Institutes of Health and the CDC are now working on the development of next-generation diagnostics to better identify the virus in the United States and throughout the world, Dr. Fauci said during the press conference.

Currently, there are no proven therapeutics for the coronavirus infection, Dr. Fauci said. Based on experiences with SARS and MERS, however, researchers are studying certain antiviral drugs that could potentially treat the virus, he said. This includes the antiviral drug remdesivir, which was developed for the treatment of the Ebola virus, and lopinavir/ritonavir (Kaletra), a combination therapy commonly used to treat HIV. In addition, monoclonal antibodies developed during the SARS outbreak are also being studied.

“Given the somewhat close homology between SARS and the new novel coronavirus, there could be some cross reactivity there that could be utilized,” he said.

Most importantly, he said, vaccine development is underway. Since China isolated the virus and published its sequence, U.S. researchers have already analyzed the components and determined an immunogen to be used in a vaccine, Dr. Fauci said. He anticipates moving to a Phase 1 trial within the next 3 months. The trial would then move to Phase 2 after another few more months for safety data.

“What we do from that point will be determined by what has happened with the outbreak over those months,” he said. “We are proceeding as if we will have to deploy a vaccine. In other words, we’re looking at the worst scenario that this becomes a bigger outbreak.”

Federal health officials, however, stressed that more data about infected patients in China is needed for research. HHS has repeatedly offered to send a CDC team to China to help with public health efforts, research, and response, but China has so far declined the offer, Secretary Azar added.

In addition, the CDC has updated its travel advisory in response to the illness. The latest travel guidance recommends that travelers avoid all nonessential travel to all parts of China.

Echoes of SARS mark 2019 novel coronavirus outbreak

Article Type
Changed

The current outbreak of severe respiratory infections caused by the 2019 novel coronarvirus (2019-nCoV) has a clinical presentation resembling the Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) outbreak that began in 2002, Chinese investigators caution.

By Jan. 2, 2020, 41 patients with confirmed 2019-nCoV had been admitted to a designated hospital in the city of Wuhan, Hubei Province, in central China. Thirteen required ICU admission and six died, reported Chaolin Huang, MD, from Jin Yin-tan Hospital in Wuhan, and colleagues.

“2019-nCoV still needs to be studied deeply in case it becomes a global health threat. Reliable quick pathogen tests and feasible differential diagnosis based on clinical description are crucial for clinicians in their first contact with suspected patients. Because of the pandemic potential of 2019-nCoV, careful surveillance is essential to monitor its future host adaption, viral evolution, infectivity, transmissibility, and pathogenicity,” they wrote in a review published online by The Lancet.

According to the U.S. Centers for Disease Control and Prevention, as of Jan. 28, 2020, the total number of 2019-nCoV cases reported in the United States stood at five, but further cases of the infection – which Chinese health officials have confirmed can be transmitted person-to-person – are expected.

Dr. Huang and colleagues note that although most human coronavirus infections are mild, SARS-CoV and the Middle East respiratory syndrome coronavirus (MERS-CoV) were responsible for more than 10,000 infections, with mortality rates ranging from 10% with SARS to 37% with MERS. To date, 2019-nCoV has “caused clusters of fatal pneumonia greatly resembling SARS-CoV,” they write.

The authors studied the epidemiological, clinical, laboratory, and radiological characteristics as well as treatments and clinical outcomes of 41 patients admitted or transferred to the Jin Yin-tan Hospital with laboratory-confirmed 2019-nCoV infections.

The median patient age was 49 years. Thirty of the 41 patients (73%) were male. Comorbid conditions included diabetes in 13 of the 41 patients (32%), hypertension in 6 (15%), and cardiovascular disease in 6.

In all 27 of the 41 patients had been exposed to the Huanan seafood market in Wuhan, the suspected epicenter of the outbreak that was shut down by health authorities on Jan. 1 of this year.

The most common symptoms at the onset of the illness were fever in all but one of the 41 patients, cough in 31, and myalgia or fatigue in 18. Other, less frequent symptoms included sputum production in 11, headache in three, hemoptysis in two, and diarrhea in one.

“In this cohort, most patients presented with fever, dry cough, dyspnoea, and bilateral ground-glass opacities on chest CT scans. These features of 2019-nCoV infection bear some resemblance to SARS-CoV and MERS-CoV infections. However, few patients with 2019-nCoV infection had prominent upper respiratory tract signs and symptoms (e.g., rhinorrhoea, sneezing, or sore throat), indicating that the target cells might be located in the lower airway. Furthermore, 2019-nCoV patients rarely developed intestinal signs and symptoms (e.g., diarrhoea), whereas about 20%-25% of patients with MERS-CoV or SARS-CoV infection had diarrhoea.”

In all, 22 patients developed dyspnea, with a median time from illness onset to dyspnea of 8 days. The median time from illness onset to admission was 7 days, median time to shortness of breath was 8 days, median time to acute respiratory distress syndrome (ARDS) was 9 days, and median time to both mechanical ventilation and ICU admission was 10.5 days.

All of the patients developed pneumonia with abnormal findings on chest CT scan. In addition, 12 patients developed ARDS, six had RNAaemia, five developed acute cardiac injury, and four developed a secondary infection. As noted before, 13 of the 14 patients were admitted to an ICU, and six died. RNAaemia is a positive result for real-time polymerase chain reaction in plasma samples. Patients admitted to the ICU had higher initial concentrations of multiple inflammatory cytokines than patients who did not need ICU care, “suggesting that the cytokine storm was associated with disease severity.”

All of the patients received empirical antibiotics, 38 were treated with oseltamivir (Tamiflu), and 9 received systemic corticosteroids.

The investigators have initiated a randomized controlled trial of the antiviral agents lopinavir and ritonavir for patients hospitalized with 2019-nCoV infection.

The study was funded by the Chinese Ministry of Science and Technology, Chinese Academy of Medical Sciences, National Natural Science Foundation of China, and Beijing Municipal Science and Technology Commission. All authors declared having no competing interests.

The median patient age was 49 years. Thirty of the 41 patients (73%) were male. Comorbid conditions included diabetes in 13 of the 41 patients (32%), hypertension in 6 (15%), and cardiovascular disease in 6.

In all 27 of the 41 patients had been exposed to the Huanan seafood market in Wuhan, the suspected epicenter of the outbreak that was shut down by health authorities on Jan. 1 of this year.

The most common symptoms at the onset of the illness were fever in all but one of the 41 patients, cough in 31, and myalgia or fatigue in 18. Other, less frequent symptoms included sputum production in 11, headache in three, hemoptysis in two, and diarrhea in one.

“In this cohort, most patients presented with fever, dry cough, dyspnoea, and bilateral ground-glass opacities on chest CT scans. These features of 2019-nCoV infection bear some resemblance to SARS-CoV and MERS-CoV infections. However, few patients with 2019-nCoV infection had prominent upper respiratory tract signs and symptoms (e.g., rhinorrhoea, sneezing, or sore throat), indicating that the target cells might be located in the lower airway. Furthermore, 2019-nCoV patients rarely developed intestinal signs and symptoms (e.g., diarrhoea), whereas about 20%-25% of patients with MERS-CoV or SARS-CoV infection had diarrhoea.”

In all, 22 patients developed dyspnea, with a median time from illness onset to dyspnea of 8 days. The median time from illness onset to admission was 7 days, median time to shortness of breath was 8 days, median time to acute respiratory distress syndrome (ARDS) was 9 days, and median time to both mechanical ventilation and ICU admission was 10.5 days.

All of the patients developed pneumonia with abnormal findings on chest CT scan. In addition, 12 patients developed ARDS, six had RNAaemia, five developed acute cardiac injury, and four developed a secondary infection. As noted before, 13 of the 14 patients were admitted to an ICU, and six died. RNAaemia is a positive result for real-time polymerase chain reaction in plasma samples. Patients admitted to the ICU had higher initial concentrations of multiple inflammatory cytokines than patients who did not need ICU care, “suggesting that the cytokine storm was associated with disease severity.”

All of the patients received empirical antibiotics, 38 were treated with oseltamivir (Tamiflu), and 9 received systemic corticosteroids.

The investigators have initiated a randomized controlled trial of the antiviral agents lopinavir and ritonavir for patients hospitalized with 2019-nCoV infection.

The study was funded by the Chinese Ministry of Science and Technology, Chinese Academy of Medical Sciences, National Natural Science Foundation of China, and Beijing Municipal Science and Technology Commission. All authors declared having no competing interests.

Wuhan virus: What clinicians need to know

Article Type
Changed

As the Wuhan coronavirus story unfolds, the most important thing for clinicians in the United States to do is ask patients who appear to have the flu if they, or someone they have been in contact with, recently returned from China, according to infectious disease experts.

“We are asking that of everyone with fever and respiratory symptoms who comes to our clinics, hospital, or emergency room. It’s a powerful screening tool,” said William Schaffner, MD, professor of preventive medicine and infectious diseases at Vanderbilt University Medical Center, Nashville, Tenn.

In addition to fever, common signs of infection include cough, shortness of breath, and breathing difficulties. Some patients have had diarrhea, vomiting, and other gastrointestinal symptoms. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure, and death. The incubation period appears to be up to 2 weeks, according to the World Health Organization (WHO).

If patients exhibit symptoms and either they or a close contact has returned from China recently, take standard airborne precautions and send specimens – a serum sample, oral and nasal pharyngeal swabs, and lower respiratory tract specimens if available – to the local health department, which will forward them to the Centers for Disease Control and Prevention (CDC) for testing. Turnaround time is 24-48 hours.

Dr. William Shaffner


The 2019 Novel Coronavirus (2019-nCoV), identified as the cause of an outbreak of respiratory illness first detected in December in association with a live animal market in Wuhan, China, has been implicated in almost 2,000 cases and 56 deaths in that country. Cases have been reported in 13 countries besides China. Five cases of 2019-nCoV infection have been confirmed in the United States, all in people recently returned from Wuhan. As the virus spreads in China, however, it’s almost certain more cases will show up in the United States. Travel history is key, Dr. Schaffner and others said.
 

Plan and rehearse

The first step to prepare is to use the CDC’s Interim Guidance for Healthcare Professionals to make a written plan specific to your practice to respond to a potential case. The plan must include notifying the local health department, the CDC liaison for testing, and tracking down patient contacts.

“It’s not good enough to just download CDC’s guidance; use it to make your own local plan and know what to do 24/7,” said Daniel Lucey, MD, an infectious disease expert at Georgetown University Medical Center, Washington, D.C.

“Know who is on call at the health department on weekends and nights,” he said. Know where the patient is going to be isolated; figure out what to do if there’s more than one, and tests come back positive. Have masks on hand, and rehearse the response. “Make a coronavirus team, and absolutely have the nurses involved,” as well as other providers who may come into contact with a case, he added.

Dr. Daniel Lucey


“You want to be able to do as well as your counterparts in Washington state and Chicago,” where the first two U.S. cases emerged. “They were prepared. They knew what to do,” Dr. Lucey said.

Those first two U.S. patients – a man in Everett, Wash., and a Chicago woman – developed symptoms after returning from Wuhan, a city of 11 million just over 400 miles inland from the port city of Shanghai. On Jan. 26 three more cases were confirmed by the CDC, two in California and one in Arizona, and each had recently traveled to Wuhan.  All five patients remain hospitalized, and there’s no evidence they spread the infection further. There is also no evidence of human-to-human transmission of other cases exported from China to any other countries, according to the WHO.

WHO declined to declare a global health emergency – a Public Health Emergency of International Concern, in its parlance – on Jan. 23. The step would have triggered travel and trade restrictions in member states, including the United States. For now, at least, the group said it wasn’t warranted at this point.
 
 

 

Fatality rates

The focus right now is China. The outbreak has spread beyond Wuhan to other parts of the country, and there’s evidence of fourth-generation spread.



Transportation into and out of Wuhan and other cities has been curtailed, Lunar New Year festivals have been canceled, and the Shanghai Disneyland has been closed, among other measures taken by Chinese officials.

The government could be taking drastic measures in part to prevent the public criticism it took in the early 2000’s for the delayed response and lack of transparency during the global outbreak of another wildlife market coronavirus epidemic, severe acute respiratory syndrome (SARS). In a press conference Jan. 22, WHO officials commended the government’s containment efforts but did not say they recommended them.

According to WHO, serious cases in China have mostly been in people over 40 years old with significant comorbidities and have skewed towards men. Spread seems to be limited to family members, health care providers, and other close contacts, probably by respiratory droplets. If that pattern holds, WHO officials said, the outbreak is containable.

The fatality rate appears to be around 3%, a good deal lower than the 10% reported for SARS and much lower than the nearly 40% reported for Middle East respiratory syndrome (MERS), another recent coronavirus mutation from the animal trade.

The Wuhan virus fatality rate might drop as milder cases are detected and added to the denominator. “It definitely appears to be less severe than SARS and MERS,” said Amesh Adalja, MD, an infectious disease physician in Pittsburgh and emerging infectious disease researcher at Johns Hopkins University, Baltimore.

SARS: Lessons learned

In general, the world is much better equipped for coronavirus outbreaks than when SARS, in particular, emerged in 2003.

Dr. Amesh Adalja

WHO officials in their press conference lauded China for it openness with the current outbreak, and for isolating and sequencing the virus immediately, which gave the world a diagnostic test in the first days of the outbreak, something that wasn’t available for SARS. China and other countries also are cooperating and working closely to contain the Wuhan virus.

“What we know today might change tomorrow, so we have to keep tuned in to new information, but we learned a lot from SARS,” Dr. Shaffner said. Overall, it’s likely “the impact on the United States of this new coronavirus is going to be trivial,” he predicted.

Dr. Lucey, however, recalled that the SARS outbreak in Toronto in 2003 started with one missed case. A woman returned asymptomatic from Hong Kong and spread the infection to her family members before she died. Her cause of death wasn’t immediately recognized, nor was the reason her family members were sick, since they hadn’t been to Hong Kong recently.

The infection ultimately spread to more than 200 people, about half of them health care workers. A few people died.

If a virus is sufficiently contagious, “it just takes one. You don’t want to be the one who misses that first patient,” Dr. Lucey said.

Currently, there are no antivirals or vaccines for coronaviruses; researchers are working on both, but for now, care is supportive.

Second U.S. coronavirus patient confirmed

Article Type
Changed

The Centers for Disease Control and Prevention has confirmed a second case of the infectious coronavirus, 2019-nCoV, in the United States at a Jan. 24, 2020, press briefing.

The first U.S. case, a traveler who entered the United States at Seattle-Tacoma International Airport, was confirmed on Jan. 20.

A Chicago resident returning from Wuhan, China, on Jan. 13, 2020, developed symptoms of the disease and contacted her health care clinician and is currently being treated in isolation at an unnamed hospital, according to Nancy Messonnier, MD, director of the National Center for Immunization and Respiratory Diseases at the CDC. The patient, a woman in her 60s, is in stable condition and remains hospitalized. She was not symptomatic on her flight to Chicago but developed symptoms in the following days after her return from Wuhan. She had limited contacts after her return, and all potential contacts are being tracked.

Dr. Messonnier said the CDC expects more cases in the United States but stressed that, although this is a serious public health threat, the risk to the American public is low. She noted that the situation is evolving rapidly and that the CDC is following the developments hour by hour.

Jennifer Layden, MD, PhD, chief medical officer and state epidemiologist with the Illinois Department of Public Health, said public health preparations made it possible to quickly identify and arrange appropriate hospitalization for this patient. Allison Arwady, MD, Chicago Department of Health commissioner, said the Illinois Department of Health partnered with the CDC to test specimens quickly, which led to the diagnosis in this patient.

So far, 63 U.S. patients have been investigated for possible infection with the 2019-nCoV; 11 so far have tested negative and 2 have tested positive. Testing of the remaining potential cases and others is ongoing.

Currently, samples from patients with suspected 2010-nCoV infections are being sent to the CDC for testing, Dr. Messonnier said. The turnaround for testing is currently 4-6 hours. Respiratory samples and some blood samples are being tested by the CDC labs.

The CDC is developing diagnostic kits for public health authorities in the United States for local testing and will work with the World Health Organization to make these kits available to the international community when possible.

Dr. Messonnier said that, at present, the incubation period for this disease appears to be about 14 days, but she suggested that further study will be required to identify the range of time for contagion. She also said it is premature to compare the 2019-nCoV with previous coronavirus outbreaks, such as severe acute respiratory syndrome (SARS) or Middle East respiratory syndrome (MERS), in terms of contagion or fatality rates.

Meanwhile, Andrew D. Mesecar, PhD, the Walther Professor in Cancer Structural Biology and head of the department of biochemistry at Purdue University, West Lafayette, Ind., said on Jan. 24 in a news release that 2019-nCoV is genetically similar to the SARS variant. “MERS virus and the SARS virus are more different genetically,” noted Dr. Mesecar, whose team received the genome of 2019-nCoV on Jan. 17 and analyzed it the next day. “But the Wuhan virus is genetically almost identical to the SARS virus and, therefore, it is expected to look and act nearly the same. In another week or two, we’ll be able to begin to see if the virus is mutating.”

Dr. Messonnier said that nonessential travel to Wuhan is not recommended. In addition, she said, and all other visitors to China need to take appropriate precautions, such as handwashing and avoiding other individuals with respiratory illness.

Screenings at five U.S. airports will continue. So far, approximately 200 flights and 2,000 travelers have been screened as of Jan. 23. No cases were reported, but one traveler has been identified for further for evaluation. Possible contacts with those suspected of infection have been identified and alerted in 22 states.

The CDC will continue to update the public and will post information on the CDC newsroom website.

Dr. Messonnier said the CDC expects more cases in the United States but stressed that, although this is a serious public health threat, the risk to the American public is low. She noted that the situation is evolving rapidly and that the CDC is following the developments hour by hour.

Jennifer Layden, MD, PhD, chief medical officer and state epidemiologist with the Illinois Department of Public Health, said public health preparations made it possible to quickly identify and arrange appropriate hospitalization for this patient. Allison Arwady, MD, Chicago Department of Health commissioner, said the Illinois Department of Health partnered with the CDC to test specimens quickly, which led to the diagnosis in this patient.

So far, 63 U.S. patients have been investigated for possible infection with the 2019-nCoV; 11 so far have tested negative and 2 have tested positive. Testing of the remaining potential cases and others is ongoing.

Currently, samples from patients with suspected 2010-nCoV infections are being sent to the CDC for testing, Dr. Messonnier said. The turnaround for testing is currently 4-6 hours. Respiratory samples and some blood samples are being tested by the CDC labs.

The CDC is developing diagnostic kits for public health authorities in the United States for local testing and will work with the World Health Organization to make these kits available to the international community when possible.

Dr. Messonnier said that, at present, the incubation period for this disease appears to be about 14 days, but she suggested that further study will be required to identify the range of time for contagion. She also said it is premature to compare the 2019-nCoV with previous coronavirus outbreaks, such as severe acute respiratory syndrome (SARS) or Middle East respiratory syndrome (MERS), in terms of contagion or fatality rates.

Meanwhile, Andrew D. Mesecar, PhD, the Walther Professor in Cancer Structural Biology and head of the department of biochemistry at Purdue University, West Lafayette, Ind., said on Jan. 24 in a news release that 2019-nCoV is genetically similar to the SARS variant. “MERS virus and the SARS virus are more different genetically,” noted Dr. Mesecar, whose team received the genome of 2019-nCoV on Jan. 17 and analyzed it the next day. “But the Wuhan virus is genetically almost identical to the SARS virus and, therefore, it is expected to look and act nearly the same. In another week or two, we’ll be able to begin to see if the virus is mutating.”

Dr. Messonnier said that nonessential travel to Wuhan is not recommended. In addition, she said, and all other visitors to China need to take appropriate precautions, such as handwashing and avoiding other individuals with respiratory illness.

Screenings at five U.S. airports will continue. So far, approximately 200 flights and 2,000 travelers have been screened as of Jan. 23. No cases were reported, but one traveler has been identified for further for evaluation. Possible contacts with those suspected of infection have been identified and alerted in 22 states.

The CDC will continue to update the public and will post information on the CDC newsroom website.

Washington state patient is first U.S. case of novel coronavirus

Article Type
Changed

The first case of the novel coronavirus, named 2019-nCoV, in the United States has been diagnosed in a traveler from China who came through Seattle-Tacoma International Airport on Jan 15, the Centers for Disease Control and Prevention announced today at a press briefing.

CDC/John Hierholzer, MD

The outbreak began at a animal and meat market in China and now has spread to at least three other countries, including Thailand, Japan and South Korea. While originally thought to be spreading from animal to person, it appears that limited person-to-person transmission is occurring, although it is currently unknown how easily this virus spreads between people.

More than 300 cases have been reported and six deaths have occurred. Fourteen health care workers have been infected.

Scott Lindquist, MD, MPH, Washington state epidemiologist, said at the briefing that the patient, a man who had been in Wuhan, arrived at Sea-Tac on Jan. 15, 2 days before airport screening had been initiated. He was symptom free at the time of his arrival and probably would not have been identified as infected with 2019-nCoV. The patient had been aware of the public health and news media coverage of 2019-nCoV and, after developing symptoms, contacted his health care provider on Jan. 19. The patient did not fly directly from Wuhan, but Dr. Lindquist said that he has been fully cooperative and has been helpful to authorities in tracing his route and contacts. The man is being treated at Providence Regional Medical Center, Everett, Wash.

The CDC obtained a specimen from the patient immediately and identified the 2019-nCoV within 24 hours.

Screening at airports is part of a multipart strategy to address this type of infection that includes public health information dissemination, patient education, as well as hospital preparation and training exercises. Currently, a strategy referred to as “funneling” is being implemented wherein travelers from China are rerouted and reticketed to one of the five airports conducting screening. At present, JFK in New York, San Francisco International, Los Angeles International, Hartsfield-Jackson Atlanta International Airport, and Chicago O’Hare International Airport are conducting inbound traveler screening.

The CDC is working in close cooperation with the Department of Homeland Security and the Federal Aviation Administration to coordinate travel screenings and reroutings. In addition, the CDC is working with the World Health Organization and the international global health community to share information about this outbreak. The CDC also has staff on site in Wuhan and is communicating with local health authorities. The CDC has activated its Emergency Operations Center to better provide ongoing support to the 2019-nCoV response. Currently, the focus is on tracing contacts and the means of transmission of this virus.

Updates on the outbreak will be posted on the CDC coronavirus website.

Travelers to three U.S. airports to be screened for novel coronavirus

Article Type
Changed

 

Three U.S. airports will begin health screening for travelers from Wuhan, China, because of an outbreak of pneumonia caused by a newly identified coronavirus called 2019-nCoV, according to an announcement from the Centers for Disease Control and Prevention.

CDC/John Hierholzer, MD

Starting today, Jan. 17, 2020, people traveling from Wuhan to New York (JFK), San Francisco (SFO), and Los Angeles (LAX) airports will be screened for symptoms associated with 2019-nCoV, which include fever, cough, and difficulty breathing.

“Based on the information that CDC has today, we believe the current risk for this virus to the general public is low,” Nancy Messonnier, MD, director of the National Center for Immunization and Respiratory Diseases, said during a CDC telebriefing.

To date, 45 cases of 2019-nCoV have been reported in Wuhan, according to the CDC. The Wuhan Municipal Health Commission said 15 patients have been cured and discharged, 5 severe cases are still being treated, and 2 patients have died. Both deaths occurred in older patients, one of whom was aged 69 years and one aged 61 years. One of the patients was known to have underlying health conditions.

Three cases of 2019-nCoV have been confirmed outside of Wuhan, one in Japan and two in Thailand. All three were travelers from Wuhan.

The virus is believed to have originated at Wuhan South China Seafood City, a market that sold seafood, chickens, bats, cats, marmots, and other wild animals. (The market has since been closed and disinfected.) The origin suggests animal-to-human transmission of 2019-nCoV, but it appears that human-to-human transmission can occur as well.

“While most of these infections seem to be happening from animals to people, there is some indication that limited person-to-person spread is happening,” Dr. Messonnier said.

Because of this potential risk, the CDC is working with the Department of Homeland Security’s Customs and Border Protection to screen travelers from Wuhan to the United States. The CDC is deploying about 100 additional staff to JFK, SFO, and LAX, where direct flights (JFK and SFO) or connecting flights (LAX) from Wuhan land.

The CDC could not confirm if exit screening is planned for people traveling abroad from Wuhan.

At the U.S. airports, travelers from Wuhan will be given a questionnaire asking about symptoms of 2019-nCoV (fever, cough, and difficulty breathing). People who exhibit symptoms will be assessed and questioned further. If they are believed to have 2019-nCoV, they will be sent to designated hospitals, where they will be examined, and samples will be collected.

Samples from patients with suspected 2019-nCoV will be sent to the CDC for analysis. Chinese health authorities made the full genome of 2019-nCoV publicly available, which will allow the CDC to confirm any cases that may arise in the United States. The CDC is currently working on a test to detect 2019-nCoV, which can be distributed to state health departments.

Earlier this month, the CDC issued a Level 1 Travel Health Notice for travelers to Wuhan and a Health Alert on 2019-nCoV. The latest information on 2019-nCoV can be found on the CDC’s Novel Coronavirus 2019 webpage.

Two new cases of coronavirus pneumonia in Thailand, Japan

Article Type
Changed

The pneumonia outbreak in China traced to a novel coronavirus appears to be contained, although at least two cases have appeared in other countries.

CDC/ Dr. Fred Murphy; Sylvia Whitfield

Health authorities in Wuhan, Hubei Province, China, identified the novel coronavirus, 2019-nCoV, responsible for the outbreak of a mysterious pneumonia that resulted in hospitalization of more than 40 patients and one death, according to the Centers for Disease Control and Prevention in a statement on the CDC website.

On Jan. 13, the Thailand’s Ministry of Public Health reported the first imported case of lab-confirmed 2019-nCoV from Wuhan. The Centers for Disease Control and Prevention stated: “The traveler with febrile illness was detected on the same day by thermal surveillance at Suvarnabhumi Airport, Thailand, and was hospitalized the same day. After temperature check and initial assessment, she was transferred to the hospital for further investigations and treatment.”

Samples from this patient tested positive for coronaviruses by reverse transcriptase-polymerase chain reaction. The genomic sequencing analysis was performed by Emerging Infectious Diseases Health Science Center, the Thai Red Cross Society, and the Thai National Institute of Health. The patient is reported to be in stable condition.

The New York Times has reported a case of 2019-nCoV in Japan in a traveler returning from Wuhan. That patient is reported to have recovered and been discharged.

Chinese health authorities transmitted the full genome of “2019 novel coronavirus,” or “2019-nCoV,” to GenBank, the genetic sequence database managed by the National Institutes of Health, and in the Global Initiative on Sharing All Influenza Data portal.

Coronaviruses are a large family of viruses. Most known human coronaviruses only cause mild respiratory disease, such as the common cold. But several coronaviruses have emerged to infect people and cause severe disease, such as has been seen with severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). The cases in the Wuhan pneumonia outbreak have tested negative for both SARS and MERS.

The outbreak in Wuhan appears to be contained. The World Health Organization reported that the Wuhan health authorities identified and followed 763 close contacts, including health care workers. No additional cases of infection with the novel coronavirus have been identified. The cluster of cases is linked to the Wuhan South China Seafood City market where – in addition to seafood – chickens, bats, marmots, and other animals were sold. That market has been closed since Jan. 1, 2020, for cleaning and disinfection.

The WHO is monitoring the situation closely and is in close contact with Chinese health authorities.

The CDC has issued a Level 1 travel alert and recommended that travelers to Wuhan, a city of over 19 million people, avoid animal and meat markets, avoid contact with sick people, and wash hands often with soap and water. Travelers who have been in Wuhan recently and who experience respiratory symptoms should notify the local health department immediately.

In addition, the CDC recommends that, for symptomatic patients with a history of travel to Wuhan, caution should be exercised in the health care setting. “Ask such patients to don a surgical mask as soon as they are identified. Conduct their evaluation in a private room with the door closed. Personnel entering the room to evaluate the patient should use contact precautions and wear an N95 disposable facepiece respirator. For patients admitted for inpatient care, implement contact and airborne isolation precautions, in addition to standard precautions, until further information becomes available. For additional infection control guidance see: www.cdc.gov/infectioncontrol/guidelines/isolation/index.html.”
