What does ‘close contact’ for COVID-19 really mean? Epidemiologist explains.

The Centers for Disease Control and Prevention has new guidance clarifying what exactly “close contact” means when it comes to transmission of SARS-Cov-2, the virus that causes COVID-19.

The previous guidance suggested that a close contact occurred when a person was within six feet of an infectious individual for 15 consecutive minutes. Now, the CDC is acknowledging that even brief contact can lead to transmission. Specifically, the new guidance suggests that those spending a total of 15 minutes of contact with an infectious person over the course of a 24-hour period should be considered in close contact.
