Health Indicator Report of Chlamydia Infections

Infections caused by the bacterium Chlamydia trachomatis are the most frequently reported notifiable disease in the United States. Chlamydia infections in both men and women are commonly asymptomatic, yet screenings occurring mostly among females produce higher rates of reported infections. Females with chlamydia infection are at risk for developing pelvic inflammatory disease (PID) and pregnant women with chlamydia can pass the infection to their infant during delivery, potentially resulting in pneumonia or neonatal ophthalmia. Both men and women may become infertile as a result of untreated chlamydia infections and susceptibility to more serious infections such as HIV also increases when an individual is infected with chlamydia.


The Sexually Transmitted Disease Program (STDP) collects and compiles over 30,000 positive STD laboratory tests per year. The STDP has neither the authority nor the manpower to compel laboratories to report race or ethnicity, therefore data are not presented by race/ethnicity.   This is Healthy New Jersey 2020 (HNJ2020) Objective STD-1.

Data Source

Communicable Disease Reporting and Surveillance System (CRDSS); Sexually Transmitted Disease Program; Division of HIV/AIDS, STD and TB Services; New Jersey Department of Health; []


Rate of newly reported chlamydia trachomatis infections by diagnosis date per 100,000 females aged 15-24 years


Number of newly reported chlamydia infections among females aged 15-24 years


Total number of females aged 15-24 years in the population

Other Objectives

'''Healthy New Jersey 2020 Objective STD-1''': Reduce the proportion of females aged 15-24 years with Chlamydia trachomatis infections to 2,425 per 100,000 female population aged 15-24 years.

How Are We Doing?

Chlamydia infections are increasing and the Healthy New Jersey 2020 target was not met. Even with a decline in testing due to the COVID-19 pandemic in 2020, the provisional number of infections (2,584) was still above the target.

What Is Being Done?

The [ NJDOH Sexually Transmitted Disease (STD) Program] strives to prevent and reduce the effects of STDs in New Jersey through prevention, education, screening, treatment, and surveillance.
