Trichomoniasis is caused by the protozoan Trichomonas
vaginalis.
It is estimated that up to one in five sexually active
women will contract trichomoniasis during her lifetime. Both men and women
can carry the infection, although symptomatic infection is more common in
women. Because trichomoniasis is sexually transmitted, male sexual
partners must also be treated, even if asymptomatic and no infection is
detected.
- Profuse discharge, often unpleasant in odour. Colour
varies from light grey to frothy yellow-green.
- Vaginal and vulval irritation.
- Usually inflamed cervix, vagina, and opening to the
vagina.
- In men there are often no symptoms, or those of
urethritis.
- Symptoms can be aggravated by sexual intercourse.
Trichomoniasis does not pose major long-term risks to
the reproductive system.
Microscopic identification from a wet preparation of a
vaginal smear is necessary. Trichomoniasis can also be coincidentally
found on a Pap smear. Trichomoniasis is rarely found on urethral smears
from men, unless a special wet mount specimen is examined microscopically.
Trichomoniasis is treated orally, with the antibiotic
tinidazole (Fasigyn) or metronidazole (Flagyl). Nausea is a common
side-effect from these drugs, and alcohol should be avoided for 2 to 3
days afterwards as it can cause a severe reaction to occur. These drugs
should not be given to pregnant or breast-feeding women.
The use of condoms during vaginal intercourse will
prevent the transmission of trichomoniasis.
Sexual practices other than vaginal intercourse will
reduce the likelihood of contracting trichomoniasis.
When trichomonal infection is present, it is important
to avoid sexual practices involving the genitals during treatment and
until a negative test result is obtained. This will aid healing and help
to prevent transmission. |
