The World Health Organization (WHO) released an updated version of: Transmission of SARS-Cov-2: Implications for Infection Prevention Precautions on July 9th, 2020.

Updates include continued discussion and research on the modes of transmission including airborne transmission.  Aerosols can develop when larger droplets evaporate and become airborne or by simply talking and breathing.

Experimental studies have shown that SARS-CoV-2 can survive between 3 and 16 hours within aerosols.

Like much of our SARS-CoV-2 knowledge, more studies are needed to confirm airborne transmission.  However, the evidence is strong enough that organizations like ASHRAE and Centers for Disease Control and Prevention (CDC) have recommended increased ventilation and filtration.
