Can COVID-19 spread through sexual intercourse?
Although COVID-19 has been detected in semen and feces, currently we do not think that the virus is spread through the sexual act. But, given that the virus is spread through respiratory droplets—which are much more likely to be shared when in close contact with another person—many sexual acts will be considered high risk. So, as the New York City Department of Health details in its safer sex and COVID-19 fact sheet, minimizing risks by exploring other avenues of meaningful interaction is suggested and recommended.
