Both HIV and HBV spread from person to person in semen, blood, or other body fluids.
For this reason, the main risk factors for HIV and HBV are the same: having sex without a condom and injection drug use.
Other people may take HIV medicines and an HBV antiviral medicine.
If you have HIV/HBV coinfection, talk to your health care provider about the best medicines for you.
Chronic HBV advances faster to cirrhosis, end-stage liver disease, and liver cancer in people with HIV/HBV coinfection than in people with only HBV infection. The best way to prevent HBV infection is to get the hepatitis B vaccine.
