- Sleeping with severe Covid-19: Lying face down was better for the lungs of people with severe Covid-19 in a study of 12 people in a hospital in Wuhan, China. The findings, described in a research letter published Monday in the American Journal of Respiratory and Critical Care Medicine, are “important for the management of patients with severe Covid-19 requiring mechanical ventilation,” said lead author Dr. Chun Pan, acknowledging the sample size was small. The doctors used a device attached to the patients’ ventilators to measure their oxygen flow, lung volume, airway pressure, and other factors while they were lying facing up or facing down, finding that the patients’ lungs functioned better in the prone (face-down) position.
- Minor mutations, one vaccine: SARS-CoV-2 is mutating at a rate that would require only one vaccine to protect the public from future infections, as opposed to a new vaccine every year, the Washington Post reported on Tuesday. In his study of over 1,000 samples of the virus, Peter Thielen, a molecular geneticist at Johns Hopkins University, found only “four to 10” genetic variations in the strains that infected people in the United States and the one that originated in Wuhan, China. This means that once a vaccine is developed (which scientists are racing to do), it will likely be effective over a long period of time, like the chicken pox or measles vaccine.
