Charlie Sheen publicly revealed in 2015 that he has been HIV-positive since around 2011. He has stated that he is uncertain exactly how he contracted the virus, but he has linked it to years of drug-fueled sexual encounters. Since his diagnosis, Sheen has been open about informing every sexual partner and taking precautions. He also disclosed that he faced extortion threats from people who knew his status, paying millions to keep it private before deciding to go public. Sheen has emphasized that he has never knowingly infected anyone with HIV. His diagnosis came after experiencing severe symptoms like cluster headaches and night sweats that led him to seek medical testing.
