US Centers for Disease Control (CDC) updates web page to say airborne virus through aerosols is the PRIMARY path for transmission of COVID: ““This is thought to be the main way the virus spreads.”

CDC (temporarily) changes web page to say: Airborne viruses, including COVID-19, are among the most contagious and easily spread. Covid-19 most commonly spreads between people who are in close contact with one another, and now says the virus is known to spread “through respiratory droplets or small particles, such as those in aerosols, produced when […]

During the 2020 COVID‐19 pandemic, an outbreak occurred following attendance of a symptomatic index case at a weekly rehearsal on 10 March of the Skagit Valley Chorale (SVC).

Jimenez, Jose, and Peng, Zhe. 2020. “Exhaled CO2 as COVID-19 infection risk proxy for different indoor environments and activities.” medRxiv, September 10, 2020.

Abstract CO2 is co-exhaled with aerosols containing SARS-CoV-2 by COVID-19 infected people and can be used as a proxy of SARS-CoV-2 concentrations indoors. Indoor CO2 measurements by low-cost sensors hold promise for mass monitoring of indoor aerosol transmission risk for COVID-19 and other respiratory diseases. We derive analytical expressions of CO2-based risk proxies and apply […]
