STI Awareness: Hepatitis B Virus and the HBV Vaccine

July 28 is World Hepatitis Day. This month’s installment of our STI Awareness series will shine the spotlight on the hepatitis B virus (HBV), which can be transmitted sexually as well as nonsexually.

Hepatitis viruses infect the liver. Hepatitis A, B, and C can be transmitted sexually, and hepatitis B is the most likely to be spread this way. HBV is present in vaginal fluids, semen, and blood. It is highly contagious and can be transmitted by most sexual activities, such as vaginal or anal intercourse, as well as oral sex. HBV can also be spread by exposure to infected blood, and an HBV-infected mother can pass the virus onto her infant during birth.

To protect yourself from HBV, make sure to use latex barriers, such as condoms and dental dams, if you are sexually active. Also, don’t use unsterilized needles; don’t share hygiene items that could have infected blood on them, such as razors and toothbrushes; and consider being vaccinated against hepatitis B.

Condoms, Caps and Dams . . . Barrier Methods for Everyone!

February is a time full of candy kisses, love, and romance. It’s a time for couples to express their love for each other with chocolate, flowers, diamonds, and yes . . . lots of sex. It’s no wonder then that February is also National Condom Month.

Barrier methods are great forms of birth control because they don’t have the same side effects as hormonal birth control. They function by keeping the sperm from ever coming in contact with the egg, preventing fertilization of the egg. Some also protect against sexually transmitted infections (STI’s).

Male Condoms
Condoms are one of the most common and widely used of all the birth control methods and the only one that can protect against STI’s. They are generally made from latex or animal membranes, such as sheep skin. The material is shaped like a penis, with an opening on one end in which the penis can be inserted. This should be done prior to any intercourse, oral or anal sex, to prevent pregnancy. The condom will then collect any semen from the penis, thus avoiding pregnancy. Latex condoms also provide a barrier between body fluids to prevent contact with STIs.

Aside from a lack of side effects, condoms are a great form of birth control for several reasons. They are cheap and easily accessible, come in a variety of options to enhance pleasure (flavored, shaped, texture, etc.), may delay premature ejaculation, and can be used with virtually any other birth control to enhance the effectiveness of pregnancy prevention. Condoms are available at almost any pharmacy, most grocery stores, and at Planned Parenthood and other health/family clinics. Planned Parenthood also services condom vending machines in the Tucson area, which has condoms available for $0.50 at various locations. The cost can vary, but generally runs about $1 per condom; at some clinics and educational programs, condoms may be available at little or no cost. Continue reading
