Now that’s a sick fetish.

Coronavirus-themed porn is going viral on streaming sites, with more than 100 videos from the bizarre genre popping up in recent days, according to a report.

The largely amateur outbreak videos — which include everything from horndogs in hazmat suits to “MILFs in quarantine” — have emerged on free sites such as pornhub.com and xHamster.com, according to Vice.

Viewers are hotter than a fever for the sickness-centric smut because fear is often fetishized, one porn actor told the outlet.

“I think people are attracted to COVID-19-themed porn the same way people who are scared of their shadow are attached to horror movies: We are all searching for things that make us come alive,” said the performer, Spicy, who has appeared in coronavirus-themed porn.

“COVID-19 is something that brings fear and mystery to pretty much everyone in the world right now.”

The amateur pornmaker appeared in a video dubbed “Bodycam Footage Investigates Deserted Wuhan,” which features a woman in a hospital gown and a man in a hazmat suit hooking up in the ground-zero city.

Other videos give new meaning to the term “protection” — as couples strip down, but keep their surgical masks on.

Another, titled “TSA Agent Detains Woman Suspected of Coronavirus,” capitalizes on fears surrounding traveling during the outbreak.

Worldwide, the deadly virus has killed more than 3,000 people and infected 90,000.
