Although there is currently no evidence that the COVID-19 virus transmits through semen or vaginal fluids, it has been detected in the semen of people recovering from COVID-19. We would thus recommend avoiding any close contact, especially very intimate contact like unprotected sex, with someone with active COVID-19 to minimize the risk of transmission

How long could the COVID-19 virus linger in your body?

But for most infected people, virus levels in the body peak between three and six days after the original infection, and the immune system clears the pathogen within 10 days. The virus shed after this period is generally not infectious.

Why are COVID-19 cases rising again?

There are a range of factors that contribute to cases rising and falling — climate, behavior, and mitigation efforts (or lack thereof) among them. Scientists are trying to zero in on what the latest increase in cases says about the durability of protection and the ongoing evolution of the virus.

When an infected person coughs, sneezes, or talks, droplets or tiny particles called aerosols carry the virus into the air from their nose or mouth. Anyone who is within 6 feet of that person can breathe it into their lungs.

When can I have sex after the COVID-19 vaccine?

So it's extremely unlikely that you'll get very sick or die from COVID-19 once you're fully vaccinated (meaning it's been at least 2 weeks since your final shot). That means that most fully vaccinated people can safely go back to doing stuff they did before the pandemic, including dating and having sex.
