The CDC guidance to wear a well-fitting mask all the time on days six to 10 should reduce the risk of transmission, but many people outside of healthcare dont have access to good masks and everyone needs to eat and drink, so this strategy may not be as safe as previous studies indicated, said co-author Caroline Guenette, MS, APNC, Director of Occupational Health at UChicago Medicine. The best option is to take a patient's sample, stick it in a dish of thriving living cells, and see what happens to the healthy cells. The odds are very slim, outside of a laboratory setting, that someone who gets a positive result on a rapid antigen test is a non-infectious person shedding large amounts of dead virus, said Kelly Wroblewski, director of infectious disease programs for the Association of Public Health Laboratories. If there's live virus, said Dirk Dittmer, a virologist at the University of North Carolina-Chapel Hill, "then the cells would die, just like the lung cells in your body would die."
