The Centers for Disease Control and Prevention now states explicitly that airborne virus can be inhaled even when one is more than six feet away from an infected individual. The new language, posted on the C.D.C.'s website, is a change from the agency’s previous position that most infections were acquired through “close contact, not airborne transmission.” As the pandemic unfolded last year, infectious disease experts warned for months that both the C.D.C. and the World Health Organization were overlooking research that strongly suggested the coronavirus traveled aloft in small, airborne particles. Several scientists on Friday, May 7, 2021, welcomed the agency’s scrapping of the term “close contact,” which they criticized as vague and said did not necessarily capture the nuances of aerosol transmission. “The C.D.C. has now caught up to the latest scientific evidence, and they’ve gotten rid of some old problematic terms and thinking about how transmission occurs.” said Linsey Mars, an aerosol expert at Virginia Tech.
