Abstract

Background

Prevalence estimates from population-based surveys do not suffer from the same biases as case-report and clinic positivity data and may be better to monitor sexually transmitted disease morbidity over time.

Methods

We estimated the prevalence of Neisseria gonorrhoeae in a nationally representative sample of persons aged 14 to 39 years participating in the National Health and Nutrition Examination Survey.

Results

From 1999 to 2008, the overall prevalence of gonorrhea was 0.27% (95% confidence interval, 0.13%–0.47%). In the 2005 to 2006 and 2007 to 2008 cycles, prevalence approached 0% and was based on too few positive sample persons to obtain reliable estimates. In 2004, most infections were found in 1 survey location.

Discussion

Given the low prevalence and geographic clustering of disease, gonorrhea estimates from national probability surveys are often imprecise and unstable. In 2008, gonorrhea testing in National Health and Nutrition Examination Survey was discontinued. Continued surveillance of gonorrhea should include case reporting and prevalence estimates from local surveys and sentinel surveillance systems.
