11. Hepatitis/HBV
There are several types of hepatitis. Although the different viruses are transmitted through various routes, they all cause damage to the liver. The type of hepatitis associated with sexual transmission is hepatitis B (HBV). Over time, chronic infection with hepatitis can lead to scarring of the liver, cirrhosis, and liver cancer. Although, there is a vaccine that can protect you against infection, approximately 1.25 million people in the United States suffer from chronic infection with HBV.
