On August 11th, the Centers for Disease Control and Prevention (CDC) announced relaxed guidance related to COVID-19 exposure. The agency is no longer recommending that people quarantine after close contact with an infected person. The CDC also removed the recommendation that people stay at least 6 feet away from others.
According to the CDC, about 95% of Americans ages 16 and older have developed some level of immunity, either from being vaccinated or infected.
