As coronavirus continues to spread around the world, face masks are in high demand as people look for ways to protect themselves. But do they really protect most people from contracting the virus? Dr Shunmay Yeung from London School of Hygiene and Tropical Medicine explains.

Health Update: Ibuprofen Results In “More Severe Illness” For “Coronavirus / Covid-19” Patients (BMJ)
From a BMJ online release (March 17, 2020):
“The finding in two randomised trials that advice to use ibuprofen results in more severe illness or complications helps confirm that the association seen in observational studies is indeed likely to be causal. Advice to use paracetamol (acetaminophen) is also less likely to result in complications.”
Scientists and senior doctors have backed claims by France’s health minister that people showing symptoms of covid-19 should use paracetamol (acetaminophen) rather than ibuprofen, a drug they said might exacerbate the condition.
Ian Jones, a professor of virology at the University of Reading, said that ibuprofen’s anti-inflammatory properties could “dampen down” the immune system, which could slow the recovery process. He added that it was likely, based on similarities between the new virus (SARS-CoV-2) and SARS I, that covid-19 reduces a key enzyme that part regulates the water and salt concentration in the blood and could contribute to the pneumonia seen in extreme cases. “Ibuprofen aggravates this, while paracetamol does not,” he said.

Health Update: The First Clinical Trial Of A “Coronavirus / Covid-19” Vaccine Begins (NIH)
From the National Institutes of Health (NIH) (March 17, 2020):
“Finding a safe and effective vaccine to prevent infection with SARS-CoV-2 is an urgent public health priority,” said NIAID Director Anthony S. Fauci, M.D. “This Phase 1 study, launched in record speed, is an important first step toward achieving that goal.”
The vaccine is called mRNA-1273 and was developed by NIAID scientists and their collaborators at the biotechnology company Moderna, Inc., based in Cambridge, Massachusetts. The Coalition for Epidemic Preparedness Innovations (CEPI) supported the manufacturing of the vaccine candidate for the Phase 1 clinical trial.
A Phase 1 clinical trial evaluating an investigational vaccine designed to protect against coronavirus disease 2019 (COVID-19) has begun at Kaiser Permanente Washington Health Research Institute (KPWHRI) in Seattle. The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, is funding the trial. KPWHRI is part of NIAID’s Infectious Diseases Clinical Research Consortium. The open-label trial will enroll 45 healthy adult volunteers ages 18 to 55 years over approximately 6 weeks. The first participant received the investigational vaccine today.
The study is evaluating different doses of the experimental vaccine for safety and its ability to induce an immune response in participants. This is the first of multiple steps in the clinical trial process for evaluating the potential benefit of the vaccine.
Health: “What It’s Like to Take a Drive-Through Coronavirus Test” (WSJ)
As coronavirus spreads across the world, countries are setting up drive-through clinics to make it easier for their citizens to get tested. WSJ’s Andrew Jeong visited a test site in South Korea to see how it works.

“Telemedicine” Is The Way To Treat “Coronavirus / Covid-19” Pandemic (NEJM)
From a New England Journal of Medicine article (March 11, 2020):
A central strategy for health care surge control is “forward triage” — the sorting of patients before they arrive in the emergency department (ED). Direct-to-consumer (or on-demand) telemedicine, a 21st-century approach to forward triage that allows patients to be efficiently screened, is both patient-centered and conducive to self-quarantine, and it protects patients, clinicians, and the community from exposure.
It can allow physicians and patients to communicate 24/7, using smartphones or webcam-enabled computers. Respiratory symptoms — which may be early signs of Covid-19 — are among the conditions most commonly evaluated with this approach. Health care providers can easily obtain detailed travel and exposure histories. Automated screening algorithms can be built into the intake process, and local epidemiologic information can be used to standardize screening and practice patterns across providers.

More than 50 U.S. health systems already have such programs. Jefferson Health, Mount Sinai, Kaiser Permanente, Cleveland Clinic, and Providence, for example, all leverage telehealth technology to allow clinicians to see patients who are at home. Systems lacking such programs can outsource similar services to physicians and support staff provided by Teladoc Health or American Well. At present, the major barrier to large-scale telemedical screening for SARS-CoV-2, the novel coronavirus causing Covid-19, is coordination of testing. As the availability of testing sites expands, local systems that can test appropriate patients while minimizing exposure — using dedicated office space, tents, or in-car testing — will need to be developed and integrated into telemedicine workflows.
Medicine Lectures: 2019 Nobel Laureates Sir Peter Ratcliffe And Professor William Kaelin (Oxford)
Sir Peter and Prof. Kaelin were awarded the Nobel Prize in Physiology and Medicine last year by the Nobel Assembly at Karolinska Institutet, in recognition of their discoveries of how cells sense and adapt to oxygen availability, an essential adaptive process central to many significant diseases. The professors respectively work for the University of Oxford and Harvard University, and shared the Nobel Prize with Prof. Gregg Semenza, a fellow researcher.
