Inside: Joe Rogan, podcasting giant dismissive of vaccination, says he has COVID-19.

Joe Rogan, one of the world’s highest paid and most influential podcast hosts, announced Wednesday he has tested positive for COVID-19 and said he’d embarked on a fringe treatment regime.

In a video posted to his Instagram account, Rogan said he felt “very weary” on Saturday and got tested for COVID-19 the following day. He said ahead of the test he quarantined from his family and “throughout the night, I got fevers and sweats and I knew what was going on.”

Rogan’s revealing his positive diagnosis comes after he dismissed to some extent the usefulness of the vaccine on his podcast, “The Joe Rogan Experience,” which is available only on Spotify. In April, Rogan told listeners that if a 21-year-old asked him if they should get vaccinated, he would suggest they do not.

Rogan did not say in the video posted Wednesday whether he’d been vaccinated. He said in an April podcast that he was scheduled to get the Johnson & Johnson vaccine prior to it being paused.

In Wednesday’s video, Rogan said he took several medications after his diagnosis, including the antiparasitic drug ivermectin, the use of which has become popular among fringe and anti-vaccine communities, and which U.S. health officials have strongly advised against.

Spotify signed a licensing deal with Rogan in May 2020 and has repeatedly touted his success in its company earnings reports. Spotify CEO Daniel Ek stood by and promoted the podcast host amid the controversy over Rogan’s April remarks.
