The study echoes the recent findings that SARS-CoV-2, the virus causing Covid-19, along with others such as MERS-CoV, influenza, measles, and the rhinoviruses that cause the common cold all spread via aerosols that can build up in indoor air and linger for hours.”Our model would suggest that, actually, aerosol generation and TB generation can happen independent of symptoms,” Ryan Dinkele, a graduate student at the University of Cape Town who presented the results, was quoted as saying by the NYT.However, the new study does not change that the TB transmission occurred via droplets — a single cough can expel more bacteria than a single breath.
