COVID-19 and masks: Doctor, may I be excused?
In the last 2 months, at least 10 patients have asked Constantine George, MD, for a written medical exemption so they won’t have to wear a mask in public. Dr. George, the chief medical officer of Vedius, an app for a travelers’ concierge medical service in Las Vegas, turned them all down.
Elena Christofides, MD, an endocrinologist in Columbus, Ohio, has also refused patients’ requests for exemptions.
“It’s very rare for someone to need an exemption,” says Albert Rizzo, MD, chief medical officer for the American Lung Association and a lung specialist at ChristianaCare Health System in Newark, Del.
The opposition is sometimes strong. Recently, a video of Lenka Koloma of Laguna Niguel, Calif., who founded the antimask Freedom to Breathe Agency, went viral. She was in a California supermarket, maskless, telling an employee she was breaking the law by requiring patrons to wear masks.
“People need oxygen,” she said. “That alone is a medical condition.” Her webpage has a “Face Mask Exempt Card” that cites the Americans with Disabilities Act and posts a Department of Justice ADA violation reporting number. The DOJ issued a statement calling the cards fraudulent.
Figuring out if a patient’s request to opt out of wearing a mask is legitimate is a ‘’new frontier” for doctors, says Mical Raz, MD, a professor in public policy and health at the University of Rochester (N.Y.), and a hospitalist at the university medical center.
Should some people skip masks?
Experts say there are very few medical reasons for people to skip masks. “If you look at the research, patients with COPD [chronic obstructive pulmonary disorder], those with reactive airway, even those can breathe through a mask,” Dr. George said. Requests for exemptions due to medical reasons are usually without basis. “Obviously, if someone is incapacitated, for example, with mental health issues, that’s case by case.”
Dr. Christofides said one of her patients cited anxiety and the other cited headaches as reasons not to wear a mask. “I told the one who asked for anxiety [reasons] that she could wear ones that were less tight.” The patient with headaches told Dr. Christofides that she had a buildup of carbon dioxide in the mask because of industrial exposure. Baloney, Dr. Christofides told her.
Dr. Rizzo says one rare example of someone who can’t wear a mask might be a patient with an advanced lung condition so severe, they need extra oxygen. “These are the extreme patients where any change in oxygen and carbon dioxide could make a difference,” he said. But “that’s also the population that shouldn’t be going out in the first place.”
Dr. Raz cowrote a commentary about mask exemptions, saying doctors are faced with difficult decisions and must keep a delicate balance between public health and individual disability needs. “Inappropriate medical exemptions may inadvertently hasten viral spread and threaten public health,” she wrote.
In an interview, she says that some people do have a hard time tolerating a mask. “Probably the most common reasons are mental health issues, such as anxiety, panic and PTSD, and children with sensory processing disorders (making them oversensitive to their environment). I think there are very few pulmonary reasons.”
CDC, professional organization guidelines
The CDC says people should wear masks in public and when around people who don’t live in the same household. Beyond that, it simply says masks should not be worn by children under age 2, “or anyone who has trouble breathing, is unconscious, incapacitated, or otherwise unable to remove the mask without assistance.”
In mid-July, four professional organizations released a statement in response to the CDC recommendation for facial coverings. Jointly issued by the American College of Chest Physicians, the American Lung Association, the American Thoracic Society and the COPD Foundation, it states in part that people with normal lungs and “even many individuals with underlying chronic lung disease should be able to wear a non-N95 facial covering without affecting their oxygen or carbon dioxide levels.”
It acknowledges that some people will seek an exemption and doctors must weigh the patient’s concerns against the need to stop the spread of the virus. “In some instances, physician reassurance regarding the safety of the facial coverings may be all that is needed,” it states.
Addressing the excuses
Here are some of the common medical reasons people give for not being able to tolerate a mask:
Claustrophobia or anxiety. Dr. Raz and others suggests a “desensitizing” period, wearing the mask for longer and longer periods of time to get used to it. Parents could suggest kids wear a mask when doing something they like, such as watching television, so they equate it with something pleasant. Switching to a different kind of mask or one that fits better could also help.
Masks cause Legionnaires’ disease. Not true, experts say. Legionnaires’ is a severe form of pneumonia, the result of inhaling tiny water droplets with legionella bacteria.
It’s difficult to read lips. People can buy masks with a clear window that makes their mouth and lips visible.
Trouble breathing. Brief periods of mask use won’t have a bad effect on oxygen levels for most people.
“There is not an inherent right to be out in a pandemic with an unmasked face,” Dr. Raz says. But “you are entitled to an accommodation.” That might be using curbside pickup for food and medication. That requires much less time wearing a mask than entering a store would.
There are no “boilerplate” cards or letters to excuse people provided by the four organizations that addressed the issue, Dr. Rizzo said. If he were to write a letter asking for an exemption, he would personalize it for an individual patient’s medical condition. As to whether a state would honor it, he cannot say. The states have a patchwork of recommendations, making it difficult to say.
Dr. Rizzo tells lung disease patients who are able to go out that wearing a mask for 15-20 minutes to do an errand won’t harm their oxygen levels. And he reminds them that having an exemption, in the form of a doctor’s letter, may bring more problems. “Even with an exemption, someone may confront them” for their lack of a face covering. People with COPD have a higher risk of getting a severe illness from COVID-19, according to the CDC.

COVID vaccine tested in people shows early promise
the company says in a
Researchers also reported some side effects in the 45 people in the phase I study, but no significant safety issues, the news release says.
The vaccine is among hundreds being tested worldwide in an effort to halt the pandemic that has killed nearly 600,000 worldwide.
A researcher testing the vaccine called the results encouraging but cautioned more study is needed. “Importantly, the vaccine resulted in a robust immune response,” Evan Anderson, MD, principal investigator for the trial at Emory University, says in a news release. Emory and Kaiser Permanente Washington Health Research Institute were the two sites for the study.
The company is already testing the vaccine in a larger group of people, known as a phase II trial. It plans to begin phase III trials in late July. Phase III trials involve testing the vaccine on an even larger group and are the final step before FDA approval.
The study results are published in The New England Journal of Medicine. The study was led by the National Institute of Allergy and Infectious Diseases of the National Institutes of Health.
Moderna’s vaccine uses messenger RNA, also called mRNA. It carries the instruction for making the spike protein, a key protein on the surface of the virus that allows it to enter cells when a person is infected. After it’s injected, it goes to the immune cells and instructs them to make copies of the spike protein, acting as if the cells have been infected with the actual coronavirus. This allows other immune cells to develop immunity.
In the study, participants were divided into three groups of 15 people each. All groups received two vaccinations 28 days apart. Each group received a different strength of the vaccine – either 25, 100, or 250 micrograms.
Every person in the study developed antibodies that can block the infection. Most commonly reported side effects after the second vaccination in the 100-microgram group were fatigue, chills, headache, and muscle pains, ranging from mild to moderately severe.
The phase II study has 300 heathy adults ages 18-55, along with another 300 ages 55 and older
Moderna says it hopes to include about 30,000 participants at the 100-microgram dose level in the U.S. for the phase III trial. The estimated start date is July 27.

Can convalescent plasma treat COVID-19 patients?
As an Episcopal priest, Father Robert Pace of Fort Worth, TX, is used to putting others first and reaching out to help. So when the pulmonologist who helped him through his ordeal with COVID-19 asked if he would like to donate blood to help other patients, he did not hesitate.
“I said, ‘Absolutely,’” Pace, 53, recalls. He says the idea was ‘very appealing.’ ” During his ordeal with COVID-19 in March, he had spent 3 days in the hospital, isolated and on IV fluids and oxygen. He was short of breath, with a heartbeat more rapid than usual.
Now, fully recovered, his blood was a precious commodity, antibody-rich and potentially life-saving.
As researchers scramble to test drugs to fight COVID-19, others are turning to an age-old treatment. They’re collecting the blood of survivors and giving it to patients in the throes of a severe infection, a treatment known as convalescent plasma therapy.
Doctors say the treatment will probably serve as a bridge until other drugs and a vaccine become available.
Although the FDA considers the treatment investigational, in late March, it eased access to it. Patients can get it as part of a clinical trial or through an expanded access program overseen by hospitals or universities. A doctor can also request permission to use the treatment for a single patient.
“It is considered an emergent, compassionate need,” says John Burk, MD, a pulmonologist at Texas Health Harris Methodist Hospital, Fort Worth, who treated Pace. “It is a way to bring it to the bedside.” And the approval can happen quickly. Burk says he got one from the FDA just 20 minutes after requesting it for a severely ill patient.
How it works
The premise of how it works is “quite straightforward,” says Michael Joyner, MD, a professor of anesthesiology at the Mayo Clinic, Rochester, MN. “When someone is recovered and no longer symptomatic, you can harvest those antibodies from their blood and give them to someone else, and hopefully alter the course of their disease.” Joyner is the principal investigator for the FDA’s national Expanded Access to Convalescent Plasma for the Treatment of Patients with COVID-19, with 1,000 sites already signed on.
Convalescent therapy has been used to fight many other viruses, including Ebola, severe acute respiratory syndrome (SARS), the “bird” flu, H1N1 flu, and during the 1918 flu pandemic. Joyner says the strongest evidence for it comes from the 1950s, when it was used to treat a rodent-borne illness called Argentine hemorrhagic fever. Using convalescent plasma therapy for this infection reduced the death rate from nearly 43% before the treatment became common in the late 1950s to about 3% after it was widely used, one report found.
Data about convalescent therapy specifically for COVID-19 is limited. Chinese researchers reported on five critically ill patients, all on mechanical ventilation, treated with convalescent plasma after they had received antiviral and anti-inflammatory medicines. Three could leave the hospital after 51-55 days, and two were in stable condition in the hospital 37 days after the transfusion.
In another study of 10 severely ill patients, symptoms went away or improved in all 10 within 1 to 3 days after the transfusion. Two of the three on ventilators were weaned off and put on oxygen instead. None died.
Chinese researchers also reported three cases of patients with COVID-19 given the convalescent therapy who had a satisfactory recovery.
Researchers who reviewed the track record of convalescent therapy for other conditions recently concluded that the treatment doesn’t appear to cause severe side effects and it should be studied for COVID-19.
Although information on side effects specific to this treatment is evolving, Joyner says they are “very, very low.”
According to the FDA, allergic reactions can occur with plasma therapies. Because the treatment for COVID-19 is new, it is not known if patients might have other types of reactions.
Who can donate?
Blood bank officials and researchers running the convalescent plasma programs say the desire to help is widespread, and they’ve been deluged with offers to donate. But requirements are strict.
Donors must have evidence of COVID-19 infection, documented in a variety of ways, such as a diagnostic test by nasal swab or a blood test showing antibodies. And they must be symptom-free for 14 days, with test results, or 28 days without.
The treatment involves collecting plasma, not whole blood. Plasma, the liquid part of the blood, helps with clotting and supports immunity. During the collection, a donor’s blood is put through a machine that collects the plasma only and sends the red blood cells and platelets back to the donor.
Clinical trials
Requirements may be more stringent for donors joining a formal clinical trial rather than an expanded access program. For instance, potential donors in a randomized clinical trial underway at Stony Brook University must have higher antibody levels than required by the FDA, says study leader Elliott Bennett-Guerrero, MD, medical director of perioperative quality and patient safety and professor at the Renaissance School of Medicine.
He hopes to enroll up to 500 patients from the Long Island, NY, area. While clinical trials typically have a 50-50 split, with half of subjects getting a treatment and half a placebo, Bennett-Guerrero’s study will give 80% of patients the convalescent plasma and 20% standard plasma.
Julia Sabia Motley, 57, of Merrick, NY, is hoping to become a donor for the Stony Brook study. She and her husband, Sean Motley, 59, tested positive in late March. She has to pass one more test to join the trial. Her husband is also planning to try to donate. “I can finally do something,” Sabia Motley says. Her son is in the MD-PhD program at Stony Brook and told her about the study.
Many questions remain
The treatment for COVID-19 is in its infancy. Burk has given the convalescent plasma to two patients. One is now recovering at home, and the other is on a ventilator but improving, he says.
About 200 nationwide have received the therapy, Joyner says. He expects blood supplies to increase as more people are eligible to donate.
Questions remain about how effective the convalescent therapy will be. While experts know that the COVID-19 antibodies “can be helpful in fighting the virus, we don’t know how long the antibodies in the plasma would stay in place,” Bennett-Guerrero says.
Nor do doctors know who the therapy might work best for, beyond people with a severe or life-threatening illness. When it’s been used for other infections, it’s generally given in early stages once someone has symptoms, Joyner says.
Joyner says he sees the treatment as a stopgap ‘’until concentrated antibodies are available.” Several drug companies are working to retrieve antibodies from donors and make concentrated antibody drugs.
“Typically we would think convalescent plasma might be a helpful bridge until therapies that are safe and effective and can be mass-produced are available, such as a vaccine or a drug,” Bennett-Guerrero says.
Even so, he says that he doesn’t think he will have a problem attracting donors, and that he will have repeat donors eager to help.
More information for potential donors
Blood banks, the American Red Cross, and others involved in convalescent plasma therapy have posted information online for potential donors. People who don’t meet the qualifications for COVID-19 plasma donations are welcomed as regular blood donors if they meet those criteria
According to the FDA, a donation could potentially help save the lives of up to four COVID-19 patients.
Father Pace is already planning another visit to the blood bank. To pass the time last time, he says, he prayed for the person who would eventually get his blood.

Data about convalescent therapy specifically for COVID-19 is limited. Chinese researchers reported on five critically ill patients, all on mechanical ventilation, treated with convalescent plasma after they had received antiviral and anti-inflammatory medicines. Three could leave the hospital after 51-55 days, and two were in stable condition in the hospital 37 days after the transfusion.
In another study of 10 severely ill patients, symptoms went away or improved in all 10 within 1 to 3 days after the transfusion. Two of the three on ventilators were weaned off and put on oxygen instead. None died.
Chinese researchers also reported three cases of patients with COVID-19 given the convalescent therapy who had a satisfactory recovery.
Researchers who reviewed the track record of convalescent therapy for other conditions recently concluded that the treatment doesn’t appear to cause severe side effects and it should be studied for COVID-19.
Although information on side effects specific to this treatment is evolving, Joyner says they are “very, very low.”
According to the FDA, allergic reactions can occur with plasma therapies. Because the treatment for COVID-19 is new, it is not known if patients might have other types of reactions.
Who can donate?
Blood bank officials and researchers running the convalescent plasma programs say the desire to help is widespread, and they’ve been deluged with offers to donate. But requirements are strict.
Donors must have evidence of COVID-19 infection, documented in a variety of ways, such as a diagnostic test by nasal swab or a blood test showing antibodies. And they must be symptom-free for 14 days, with test results, or 28 days without.
The treatment involves collecting plasma, not whole blood. Plasma, the liquid part of the blood, helps with clotting and supports immunity. During the collection, a donor’s blood is put through a machine that collects the plasma only and sends the red blood cells and platelets back to the donor.
Clinical trials
Requirements may be more stringent for donors joining a formal clinical trial rather than an expanded access program. For instance, potential donors in a randomized clinical trial underway at Stony Brook University must have higher antibody levels than required by the FDA, says study leader Elliott Bennett-Guerrero, MD, medical director of perioperative quality and patient safety and professor at the Renaissance School of Medicine.
He hopes to enroll up to 500 patients from the Long Island, NY, area. While clinical trials typically have a 50-50 split, with half of subjects getting a treatment and half a placebo, Bennett-Guerrero’s study will give 80% of patients the convalescent plasma and 20% standard plasma.
Julia Sabia Motley, 57, of Merrick, NY, is hoping to become a donor for the Stony Brook study. She and her husband, Sean Motley, 59, tested positive in late March. She has to pass one more test to join the trial. Her husband is also planning to try to donate. “I can finally do something,” Sabia Motley says. Her son is in the MD-PhD program at Stony Brook and told her about the study.
Many questions remain
The treatment for COVID-19 is in its infancy. Burk has given the convalescent plasma to two patients. One is now recovering at home, and the other is on a ventilator but improving, he says.
About 200 nationwide have received the therapy, Joyner says. He expects blood supplies to increase as more people are eligible to donate.
Questions remain about how effective the convalescent therapy will be. While experts know that the COVID-19 antibodies “can be helpful in fighting the virus, we don’t know how long the antibodies in the plasma would stay in place,” Bennett-Guerrero says.
Nor do doctors know who the therapy might work best for, beyond people with a severe or life-threatening illness. When it’s been used for other infections, it’s generally given in early stages once someone has symptoms, Joyner says.
Joyner says he sees the treatment as a stopgap ‘’until concentrated antibodies are available.” Several drug companies are working to retrieve antibodies from donors and make concentrated antibody drugs.
“Typically we would think convalescent plasma might be a helpful bridge until therapies that are safe and effective and can be mass-produced are available, such as a vaccine or a drug,” Bennett-Guerrero says.
Even so, he says that he doesn’t think he will have a problem attracting donors, and that he will have repeat donors eager to help.
More information for potential donors
Blood banks, the American Red Cross, and others involved in convalescent plasma therapy have posted information online for potential donors. People who don’t meet the qualifications for COVID-19 plasma donations are welcomed as regular blood donors if they meet those criteria
According to the FDA, a donation could potentially help save the lives of up to four COVID-19 patients.
Father Pace is already planning another visit to the blood bank. To pass the time last time, he says, he prayed for the person who would eventually get his blood.

As an Episcopal priest, Father Robert Pace of Fort Worth, TX, is used to putting others first and reaching out to help. So when the pulmonologist who helped him through his ordeal with COVID-19 asked if he would like to donate blood to help other patients, he did not hesitate.
“I said, ‘Absolutely,’” Pace, 53, recalls. He says the idea was ‘very appealing.’ ” During his ordeal with COVID-19 in March, he had spent 3 days in the hospital, isolated and on IV fluids and oxygen. He was short of breath, with a heartbeat more rapid than usual.
Now, fully recovered, his blood was a precious commodity, antibody-rich and potentially life-saving.
As researchers scramble to test drugs to fight COVID-19, others are turning to an age-old treatment. They’re collecting the blood of survivors and giving it to patients in the throes of a severe infection, a treatment known as convalescent plasma therapy.
Doctors say the treatment will probably serve as a bridge until other drugs and a vaccine become available.
Although the FDA considers the treatment investigational, in late March, it eased access to it. Patients can get it as part of a clinical trial or through an expanded access program overseen by hospitals or universities. A doctor can also request permission to use the treatment for a single patient.
“It is considered an emergent, compassionate need,” says John Burk, MD, a pulmonologist at Texas Health Harris Methodist Hospital, Fort Worth, who treated Pace. “It is a way to bring it to the bedside.” And the approval can happen quickly. Burk says he got one from the FDA just 20 minutes after requesting it for a severely ill patient.
How it works
The premise of how it works is “quite straightforward,” says Michael Joyner, MD, a professor of anesthesiology at the Mayo Clinic, Rochester, MN. “When someone is recovered and no longer symptomatic, you can harvest those antibodies from their blood and give them to someone else, and hopefully alter the course of their disease.” Joyner is the principal investigator for the FDA’s national Expanded Access to Convalescent Plasma for the Treatment of Patients with COVID-19, with 1,000 sites already signed on.
Convalescent therapy has been used to fight many other viruses, including Ebola, severe acute respiratory syndrome (SARS), the “bird” flu, H1N1 flu, and during the 1918 flu pandemic. Joyner says the strongest evidence for it comes from the 1950s, when it was used to treat a rodent-borne illness called Argentine hemorrhagic fever. Using convalescent plasma therapy for this infection reduced the death rate from nearly 43% before the treatment became common in the late 1950s to about 3% after it was widely used, one report found.

CDC issues new return-to-work guidelines
The Centers for Disease Control and Prevention is releasing new guidance on return-to-work rules for critical workers exposed to a COVID-19 case, or a suspected case, replacing previous guidance to stay home for 14 days.
“One of the most important things we can do is keep our critical workforce working,” CDC Director Robert Redfield said at a White House briefing on April 8. “In certain circumstances they can go back to work,” he said.
Neither Redfield nor the other governmental officials specified what counts as an essential worker, although it has generally referred to food-service and health care workers.
They must take their temperature before work, wear a facial mask at all times and practice social distancing when at work, the new guidance says. They cannot share headsets or other objects used near the face.
Employers must take the worker’s temperature and assess each one for symptoms before work starts, sending a worker home if he or she is sick. Employers must increase the cleaning of frequently used surfaces, increase air exchange in the building and test the use of face masks to be sure they do not interfere with workflow.
Pressed on whether he would reopen the country at the end of the 30-day Stop the Spread effort on April 30 — since one model has revised the U.S. death toll down from 100,000-240,000 to 61,000 — President Donald Trump said meetings will take place soon to discuss the decision and that he will ‘’rely very heavily” on health experts.
“We know now for sure that the mitigation we have been doing is having a positive effect,” said Anthony Fauci, MD, a coronavirus task force member and director of the National Institute of Allergy and Infectious Diseases.
