More on the importance of addressing aerosol transmission and the steps needed to control exposures can be found in the letter several of us sent to federal COVID-19 leaders in February 2021.

We must control inhalation exposure of small aerosol particles to end this pandemic.ĬDC must immediately update and strengthen its guidelines and recommendations to protect the public and workers for inhalation exposures to SARS-CoV-2. Mitigation measures are also needed to limit exposures. Moreover, OSHA must issue an Emergency Temporary Standard to control workplace exposures, including inhalation exposure, as soon as possible in order to protect workers and reopen the economy safely.Īs CDC has made clear, vaccination alone will not stop this pandemic. To slow transmission and save lives, it is crucial that CDC update its guidance and recommendations to address and highlight the importance of improved ventilation and using NIOSH approved respirators, especially in indoor locations where the virus may accumulate in the air.

There is clear consensus among aerosol scientists and epidemiologists that inhalation of small aerosol particles, including at distances of greater than six feet, is a major driver of the COVID-19 pandemic. It can easily happen indoors in a poorly ventilated environment, when people are not wearing masks. We know that transmission at distances beyond 6 feet occurs because of superspreader events, careful studies of smaller outbreaks, and the physics of aerosols. This will lead people to continue to think that maintaining distance is sufficient to prevent transmission. In that document CDC says that breathing in small droplets and particles (i.e., aerosols) that contain the virus when people are far apart or have been in the same enclosed space for more than a few minutes is UNCOMMON (our emphasis).
