  • Recently, the CDC revised its guidelines for combating respiratory infections, emphasizing the need to lower indoor airborne particle concentrations.

  • This is the result of a decline in COVID and flu cases since December.

  • The CDC now emphasizes proper ventilation as a crucial tactic in addition to immunization and hand hygiene.

  • They stress that ventilation is only one layer of defense and not a perfect one.

  • Good ventilation techniques are beneficial all year, but particularly under the following circumstances:

  1. There are many viruses in the community.

  2. Individuals are either ill, recuperating, or exposed to illness.

  3. People are susceptible to serious illnesses.

  • The recommendations include the following actions to enhance ventilation:

  1. Taking in a breath of fresh outdoor air.

  2. Ensuring that HVAC systems are operating properly; MERV-13 or higher filters are preferred.

  3. Additional actions such as exhaust venting and air circulation, air purifiers, and UV air treatment.

  • The CDC also suggests using portable CO2 monitors to gauge indoor air quality and recommends moving activities outdoors whenever possible to further reduce transmission risk.
