“Two and a Half Men” alum Charlie Sheen reportedly had the human immunodeficiency virus, the agent that causes AIDS, for four years, but his so-called viral load is now undetectable and HIV cannot be found in his blood, TMZ reported Monday.

Sheen, 50, has known he was HIV-positive for two years, possibly more, sources told TMZ. After taking medication for the virus, it is now “undetected,” an insider said. Generally, HIV-positive people remain undetectable only as long as they stay on their medication. They are not cured.

If the information is accurate, Sheen would be in a similar situation as former Los Angeles Lakers star Magic Johnson. The basketball player shocked the world when he revealed he was HIV-positive in 1991; several years later he said the virus was “undetected” in his blood. He has been in apparent good health to this day.

Twitter users made the comparison to Johnson on the 140-character social media platform Monday, also throwing in distasteful comments about Sheen having “tiger blood.” The Hollywood actor famously claimed he was special during a 2011 interview. “I'm different. I have a different constitution, I have a different brain, I have a different heart. I got tiger blood, man. Dying's for fools, dying's for amateurs,” he said.

Sheen’s second ex-wife, Brooke Mueller, reportedly knew about the diagnosis. “I had a drug-induced psychotic break at Charlie’s after doing drugs with Charlie for that many days. I couldn’t handle the HIV news. Just six months ago I was diagnosed with the eye disease and then Charlie potentially giving me HIV…” she said in a reported text, according to Radar online.

The news first came from a report by the National Enquirer, and Sheen is slated to discuss his health on NBC’s “Today” show Tuesday morning with Matt Lauer. The actor will “make a revealing personal announcement,” the show claimed.

Publicist Howard Bragman confirmed Sheen will talk about having HIV. “The interview could open up a lot of sympathy for him, but he has to be concerned about a fear of litigation from former sexual partners,” Bragman told People magazine Monday. “You don’t take that lightly.”

If Sheen's viral load is indeed undetectable, he would be unlikely to infect a sex partner.
