What are the current recommendations on airborne transmission of COVID-19? There is a growing consensus in the scientific community that transmission of COVID-19 via airborne bioaerosols is a concerning likelihood. As the COVID-19 pandemic continues, preventive measures must be taken everywhere there is a potential risk for transmission of the viral particles. To reduce the potential of COVID-19 infection incidence among WWTP workers, processes which produce bioaerosols should be covered, and workers should be encouraged to use protective wears. 2020-09-03 · An outbreak of COVID-19 in an apartment building in China may have been caused by fecal aerosol transmission through bathrooms connected by drainage pipes, according to research published in the The course of COVID-19 caused by the SARS-CoV-2 may be aggravated by bioaerosols containing other viruses, bacteria, and fungi, occurring mainly in the occupational environment.
