Oh, what a joyous day for science! In the tropical paradise of Brazil, from July 2017 to June 2019, a group of intrepid researchers decided to play a game of “Where’s Zika?” with 260 lucky participants. These human guinea pigs, 184 women and a mere 76 men, were all blessed with symptomatic Zika virus (ZIKV) infections. The goal? To find out how long this pesky virus likes to hang out in the most delightful of places: plasma, urine, saliva, sweat, rectal swabs, vaginal secretions, breast milk, and, for that extra bit of fun, semen.

And guess what? ZIKV was the guest that just wouldn’t leave, especially loving extended vacations in urine, sweat, rectal swabs, and semen. The party king of them all was semen, where ZIKV set up camp for the longest time, probably throwing microscopic raves with high viral loads.

But wait, there’s more! The speed at which ZIKV packed its bags and left was influenced by a smorgasbord of factors: age, sex, whether you could read good, your body’s love for donuts, non-purulent conjunctivitis (because purulent is just too mainstream), joint pain, and a history of yellow fever vaccination. Because, why not? The virus’s departure times varied based on its choice of bodily fluid Airbnb.

And just when you thought it was safe to go back in the water, surprise! ZIKV pulled a classic horror movie move with recurrent detection events after everyone thought it was gone. The moral of the story? Keep an eye out, because ZIKV is the gift that keeps on giving, and we need to be ready with the welcome—or rather, goodbye—mat.
