The CDC updated guidance to its “How COVID-19 Spreads” website on Tuesday.
Based on current science, the CDC believes that people are more likely to become infected the longer and closer they are to a person with COVID-19.
According to a press release, the latest update acknowledges the existence of some published reports that show uncommon circumstances where people with the virus infected others who were more than six feet away or shortly after the COVID-19-positive person left an area. In these circumstances, CDC officials say transmission happened in poorly ventilated and enclosed spaces that often involved activities that caused heavier breathing, like singing or exercise. Environments like this could possibly contribute to the buildup of virus-carrying particles, health officials say.
CDC’s recommendations on how people can protect themselves remain the same based on existing science:
- Stay at least six feet away from others
- Wear a mask that covers the nose and mouth
- Wash hands frequently
- Clean touched surfaces often
- Stay home when sick
