Genital warts (HPV)

Human papillomavirus infection (HPV) is a very common STD. Different types of HPV exist and cause different conditions. Some HPVs cause common warts that are not STDs, and other types are spread during sexual activity and cause genital warts. Still other types are the cause of precancerous chances and cancers of the cervix in women. Most people with HPV infection do not develop genital warts or cancers, and the body is often able to clear the infection on its own. It is currently believed that over 75% of sexually active people have been infected at some point in life. When HPV causes genital warts in men, the lesions appear as soft, fleshy, raised bumps on the penis or anal area. Sometimes they may be larger and take on a cauliflower-like appearance.

There is no cure for HPV infection, but it often resolves on its own. Treatments to destroy or remove genital warts are also available. Vaccines are available for boys and girls that confer immunity to the most common HPV types.

Hepatitis

Hepatitis is inflammation of the liver. Hepatitis B and hepatitis C are two viral diseases that can be transmitted by sexual contact. Both the hepatitis B virus (HBV) and hepatitis C virus (HCV) are transmitted by contact with the blood of an infected individual or by sexual activity, similar to the HIV virus. HBV may not cause symptoms, but it causes symptoms of acute hepatitis in about 50% of infections. The primary danger with HPV infection is that around 5% of those infected progress to have long-term liver damage, or chronic hepatitis B. People with chronic hepatitis B are at increased risk for the development of liver cancer. There is a very effective vaccine available for the prevention of hepatitis B. Treatment of acute hepatitis involves supportive care and rest, although those with chronic hepatitis may be treated with interferon or antiviral medications.

Unlike HBV, HCV is rarely transmitted by sexual contact and is usually spread by contact with the blood of an infected person. Still, it is possible to transmit this virus as a result of sexual contact. Most people infected with HCV have no symptoms, so a delayed or missed diagnosis is common. In contrast to hepatitis B, most people with HCV infection (75% to 85% of people infected) develop chronic infection with the possibility of liver damage. There is also no vaccine available against HCV.
