STD
- Trichomoniasis
What
is trichomoniasis?
| Trichomoniasis
is a common sexually transmitted disease (STD) that affects
both women and men, although symptoms are more common
in women. |
What causes trichomoniasis?
| Trichomoniasis
is caused by the single-celled protozoan parasite Trichomonas
vaginalis. The vagina is the most common site of infection
in women, and the urethra is the most common site of infection
in men. |
How
do people get trichomoniasis?
| Trichomoniasis
is a sexually transmitted disease that is spread through
penis-to-vagina intercourse or vulva-to-vulva contact
with an infected partner. Women can acquire the disease
from infected men or women, whereas men usually contract
it only from infected women. |
How
common is trichomoniasis?
|
Trichomoniasis is the most common curable STD in young,
sexually active women. An estimated 5 million new cases
occur each year in women and men. |
What
are the signs and symptoms of trichomoniasis?
Most
men with trichomoniasis do not have signs or symptoms.
Men with symptoms may have an irritation inside the penis,
mild discharge, or slight burning after urination or ejaculation.
Many women do have signs or symptoms of infection. In
these women, trichomoniasis causes a frothy, yellow-green
vaginal discharge with a strong odor. The infection may
also cause discomfort during intercourse and urination.
Irritation and itching of the female genital area and,
in rare cases, lower abdominal pain can also occur. |
When
do symptoms appear?
| Symptoms
usually appear within 5 to 28 days of exposure in women. |
What
are the complications of trichomoniasis?
| Trichomoniasis
in pregnant women may cause premature rupture of the membranes
and preterm delivery. The genital inflammation caused
by trichomoniasis might also increase a woman's risk of
acquiring HIV infection if she
is exposed to HIV. Trichomoniasis in a woman who is also
infected with HIV can increase the chances of transmitting
HIV infection to a sex partner. |
How
is trichomoniasis diagnosed?
| To
diagnose trichomoniasis, a health care provider must perform
a physical examination and laboratory test. In women,
a pelvic examination can reveal small red ulcerations
on the vaginal wall or cervix. Laboratory tests are performed
on a sample of vaginal fluid or urethral fluid to look
for the disease-causing parasite. The parasite is harder
to detect in men than in women. |
Who
is at risk for trichomoniasis?
|
Any
sexually active person can be infected with trichomoniasis. |
What is the treatment for trichomoniasis?
| Trichomoniasis
can usually be cured with a specific prescription drug
given by mouth in a single dose. The symptoms of trichomoniasis
in infected men may disappear within a few weeks without
treatment. However, an infected man, even a man who has
never had symptoms or whose symptoms have stopped, can
continue to infect a female partner until he has been
treated. Therefore, both partners should be treated at
the same time to eliminate the parasite. Persons being
treated for trichomoniasis should avoid sex until they
and their sex partners complete treatment and have no
symptoms. The prescription drug treatment can be used
by pregnant women. |
How
can trichomoniasis be prevented?
|
|
Use
condoms correctly every time you have sex. |
|
|
The
use of latex or polyurethane condoms during vaginal intercourse
can prevent the transmission of trichomoniasis. However,
condoms do not provide complete protection from all STDs.
Sores and lesions of other STDs on infected men and women
may be present in areas not covered by the condom, resulting
in transmission of infection to another person. |
|
|
Limit
the number of sex partners, and do not go back and forth
between partners. |
|
|
Practice
sexual abstinence, or limit sexual contact to one uninfected
partner. |
If
you think you are infected, avoid sexual contact and see
a health care provider.
Any genital symptoms such as discharge or burning during
urination or an unusual sore or rash should be a signal
to stop having sex and to consult a health care provider
immediately.
If you are told you have trichomoniasis or any other STD
and receive treatment, you should notify all of your recent
sex partners so that they can see a health care provider
and be treated. |
