Sexual Disease

Sexually Transmitted Disease

The Child Abuse Team at Cincinnati Children's Hospital Medical Center provides the following table as a guide for health care professionals in interpreting laboratory test results for Chlamydia, Chlamydia Trachomatis.

Infection SitesVagina, cervix, urethra, rectum

Incubation Period
and Symptoms

Most chlamydia infections do not cause symptoms. Tissue culture tests should be positive five to seven days after contact. Identification earlier than this is very unlikely.
TransmissionPerinatal infection may be unrecognized for years. Asymptomatic vaginal and rectal perinatal infections have been documented for up to three years.

A chlamydia infection should be presumed to be from sexual abuse if perinatal infection has been excluded.

Diagnostic TestsThe only acceptable method is positive bacterial tissue CULTURE. Misidentification will occur if other methods are used.
