Health Indicator Report of Chlamydia Rates

Chlamydia is the most common bacterial sexually transmitted disease. Even though symptoms of chlamydia are usually mild or absent, serious complications that cause irreversible damage, including infertility, can occur "silently" before a woman ever recognizes a problem(1). It is the leading preventable cause of infertility, and screening and treatment are the best means of preventing it.

Data Interpretation Issues

Rates are partly a function of how much testing is done - the more you test, the more you find - which is why females have roughly three times the number of reported cases as males. Testing increased throughout the 1990s, and the number of new cases jumped in 2004 due to new nucleic acid amplitude testing (NAAT) technology which is much more sensitive than previous culture tests. NAAT has been the primary testing method to date.

How Are We Doing?

Overall, chlamydia rates have been increasing from 2011 (547.0 per 100,000 population) to 2017 (645.1 per 100,000 population). In 2017, chlamydia rates were highest in the Black/African American race/ethnicity category (1097.8 per 100,000), second highest in the American Indian/Alaska Native population, (817.4 per 100,000 population), and third highest in the Hispanic category (497.9 per 100,000). The lowest rates were found in the White category (268.8 per 100,000 population) and Asian/Pacific Islander category (133.5 per 100,000) respectively. By county, the highest Chlamydia rate for 2017 was found in McKinley county (904.2 per 100,000), followed by Cibola County (898.4 per 100,000) and San Juan County (864.8 per 100,000). It is unknown whether this is an actual increase in rates or due to better testing and detection activities.

How Do We Compare With the U.S.?

Chlamydia rates in New Mexico have consistently ranked higher than U.S. rates from year 2011 to 2017. In 2017, New Mexico had the 4th highest Chlamydia rate in the U.S.

What Is Being Done?

Chlamydia testing is performed on females under age 26 at approximately 200 test sites including 54 public health offices and family planning and other provider agreement sites, in addition to routine treatment and surveillance activities.

Evidence-based Practices

Despite an a recommendation from the U.S Preventive Services Task Force to annually screen all sexually active females under age 25, data from health plans shows that fewer than 50% of that group actually gets screened each year. Chlamydia is the leading preventable cause of infertility, and screening and treatment are the best means of preventing it.
