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.

Can you contract COVID-19 through sexual intercourse?

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
