1. Infographic chart. SARS-CoV-2 AIRBORNE INFECTION PROBABILITY ESTIMATED BY USING INDOOR CO2 Outpatient consultation with four individuals in the room, a doctor, a nurse, a medical assistant, and an infected patient, talking to each other, the exposure time was 15 min. When masks are worn, they are worn by everyone in the room. Iwamura, N,, Tsutsumi, K. SARS-CoV-2 airborne infection probability estimated by using indoor carbon dioxide.

The X axis is the reading on a CO2 monitor. At 600 ppm, No mask is at 30%, Baggy blue at 8% N95 at under 1% At 800 ppm, No mask is at 57%, baggy blue at 19%, N95 at 1% at 1000 ppm, No mask is at 74%, baggy blue at 29%, N95 at 2% at 1500 ppm, No mask is at 92%, baggy blue at 48%, N95 at 3%.
