Indicator Report - Chlamydia Cases

Why Is This Important?

Infections caused by the bacterium Chlamydia trachomatis are the most frequently reported notifiable disease in Utah, with 7,616 cases reported in 2012. Two-thirds of the reported cases were among persons between 15 and 24 years of age. The overall rate for chlamydia in Utah in 2012 was 266.7 cases per 100,000 persons.

Females with chlamydia infection are at risk for developing pelvic inflammatory disease (PID), and both men and women may become infertile as a result of untreated chlamydia infections. Untreated chlamydia infections can damage the reproductive systems of both males and females. Susceptibility to more serious infections such as HIV also increases when an individual is infected with chlamydia. In addition, pregnant women with chlamydia can pass the infection to their infant during delivery, potentially resulting in pneumonia or neonatal ophthalmia.
