Which STI can lead to serious health issues such as liver disease or cancer?

Hepatitis B is a viral infection that primarily affects the liver and can lead to serious health complications, including chronic liver disease, cirrhosis, and liver cancer. It is transmitted through contact with infectious body fluids, such as blood, semen, and vaginal secretions. The risk of developing chronic hepatitis B infection is higher if the virus is contracted at a young age, and it can remain dormant for years before causing serious health problems. Comprehensive vaccination programs exist to help prevent the spread of hepatitis B, underscoring the importance of awareness and prevention regarding this STI. The other STIs listed, while they can also have serious health implications, do not directly correlate with liver disease or cancer in the same way that hepatitis B does.
