Cause:
Bacterium Chlamydia
trachomatis.
Illness and treatment:
Asymptomatic infection is common. There may be pain during
urination or abnormal genital discharge. Females can have
abdominal pain due to pelvic inflammatory disease, which can
cause infertility or ectopic pregnancy. The patient and sexual
partners should take appropriate antibiotics. Treated
patients
should be retested in 3 to 4 months.
Sources:
Chlamydial infection is
sexually transmitted or may be acquired at birth.
Additional risks:
Disease rates are highest among sexually active adolescents
and young adults. Female adolescents are physiologically
more susceptible to infection than older women. Perinatal
infection can result in neonatal conjunctivitis or
pneumonia.
Prevention:
Use safe sexual practices to
reduce transmission. Screen sexually active women at risk to
detect infection in asymptomatic patients. If Chlamydia is found, also
screen or treat for gonorrhea.
Recent Washington trends:
Each year over 20,000 cases are reported.
2010:
21,401 cases were reported (317.8 cases/100,000 population).
Purpose of Reporting and
Surveillance
-
To assess trends in epidemic patterns,
understand the impact of the burden of disease on
populations, the health care infrastructure, and to better
target population-level disease prevention efforts
-
To assure the adequate treatment of infected
individuals in order to reduce the duration of
infectiousness and prevent sequelae of infection. (e.g., PID,
ectopic pregnancy, infertility)
-
To identify cases in a timely fashion in
order to interrupt the chain of infection through
patient-level interventions such as management of sexual
contacts and behavioral risk reduction counseling
