Understanding Hepatitis B: Symptoms, Treatment, and Prevention: Hepatitis B is the most frequently sexually transmitted form of hepatitis. The good news about hepatitis B is that there is a vaccine for it and most school aged children in America have the vaccine so most people actually are vaccinated against hepatitis B. People who are at risk for hepatitis B would be those who have sex with people who are infected with hepatitis B and don't use barriers or protection. Hepatitis B is transmitted through infectious fluids such as semen, vaginal secretions, blood, and urine and saliva. So it's quite infectious. Hepatitis B often does not have symptoms so someone might not know they have it and the only way to tell if you have it is to get a blood test which will show the presence of the virus in your bloodstream. Unfortunately, there are not treatments for hepatitis B, although for most people hepatitis B goes away by itself within 7 to 9 weeks. Some people remain carriers and they can transmit hepatitis B through their entire life but as I said for most people, hepatitis B will go away on its own. One of the best ways to prevent infection from hepatitis B is to use a barrier method such as a latex condom or a dental dam or a female condom in order to prevent infectious fluids from entering your body or coming into contact with an infectious fluid. There's no 100% effective prevention of hepatitis B however using barrier methods is the best protection that you can have at this time.
