Comparing strategies for the mitigation of SARS-CoV-2 airborne infection risk in tiered auditorium venues
Comparing strategies for the mitigation of SARS-CoV-2 airborne infection risk in tiered auditorium venues

study on COVID-19 in auditoriums found displacement ventilation minimized infection risk, while natural ventilation had highest spread.

Masks, shorter events, and lower occupancy helped reduce risks.

Can the infection risk in elevators be negligible? A comparative study of airborne infection probability in elevators and conference rooms
Can the infection risk in elevators be negligible? A comparative study of airborne infection probability in elevators and conference rooms

“this study investigated the airborne transmission of respiratory diseases in the hospital elevator by comparison to the conference room.”

“The results showed that the infection probability in the elevator with 5 min was higher than that in the conference room with 50 min.”

Outbreak investigation of airborne transmission of Omicron (B.1.1.529) - SARS-CoV-2 variant of concern in a restaurant: Implication for enhancement of indoor air dilution
Outbreak investigation of airborne transmission of Omicron (B.1.1.529) - SARS-CoV-2 variant of concern in a restaurant: Implication for enhancement of indoor air dilution
In May of 2021, Hong Kong required air purifers be placed in their restaurants after papers like this showed that you could be infected in just 19 minutes, median exposure time 34 minutes, while eating at a restaurant.

The 60-Year-Old Scientific Screwup That Helped Covid Kill
The 60-Year-Old Scientific Screwup That Helped Covid Kill

Oops! Looks like Covid IS airborne, folks.

“All pandemic long, scientists brawled over how the virus spreads. Droplets! No, aerosols! At the heart of the fight was a teensy error with huge consequences…”
