There is a wide range of sexually transmitted diseases (STDs) that sexually active Vermonters may be exposed to, or infected with, other than HIV, chlamydia, gonorrhea and syphilis. These germs may be viruses (HPV, genital herpes, hepatitis B, hepatitis A,) bacteria (bacterial vaginosis) or parasites (pubic lice or crabs, scabies, trichomonaisis). Some of these are the most common sexually transmitted infections in the U.S. Many STDs are treatable or can be cured, but the medications differ from germ to germ. The populations who are most affected by individual STDs are varied. Treatments and prevention methods for each of these germs often differ as well.
