CDC Releases New Ventilation Guidelines For Indoor Environments To Reduce Covid-19 Risk
The U.S. Centers for Disease Control and Prevention (CDC) today released new guidelines on the use of ventilation strategies to reduce the risk of exposure to the SARS-CoV2 coronavirus in indoor settings.
Indoor environments have long been known to be riskier for the transmission of viral particles than outdoor environments, largely due to relative lack of airflow and confined spaces, allowing viral particles to accumulate more than they typically do outside.
Scientists have been arguing since the start of the pandemic that ventilation strategies are a vital way to mitigate the risk of infection in these environments, but the majority of public health communication in the U.S. has focused on physical distancing, handwashing and masking. All of these are doubtlessly important, but the new CDC advice on ventilation hopes to add an additional layer of mitigation to reduce risk of transmission in indoor environments.
