Men can carry the protozoa in the urethra or prostate but usually have no symptoms. Transmission is possible between two women if one partner's infected discharge comes in contact with the other partner's vulva. There may be non-sexual transmission because the protozoa can survive in warm, moist areas such as whirlpools and saunas. If you are infected with vagintis it is necessary to avoid vaginal penetration or close contact of vaginal secretions during treatment. Women with vaginitis should also stay out of public baths so that the condition does not spread.
Condoms are a means to reduce the risks of infection.
The antibiotic metronidazole is prescribed to treat trichmonas vaginitis. It may have some unpleasant side effects such as nausea and an unpleasant taste in the mouth. Please consult your physician for more details.
