There's little guidance, though, when it comes to sex in the age of Covid-19.
So three Harvard physicians examined the likelihood of coronavirus infection in a number of sex activities. And to better prevent infection during sex between partners who haven't been isolating together, people should wear masks and avoid kissing, the authors write.
These and more recommendations were published in the Annals of Internal Medicine.
How sex could help coronavirus spread
Coronavirus's sexual transmissibility hasn't been rigorously studied, but we do know that it's a highly contagious respiratory illness that spreads through droplets like coughs, sneezes and spit.
"The sexual health implications of these recommendations have received little attention, even though it appears that all forms of in-person sexual contact carry risk for transmission of the virus," said Dr. Jack Turban, study lead author and resident at Harvard Medical School, where he studies the mental health of transgender youth.
