Trends in Neisseria gonorrhoeae Incidence Among HIV-Negative and HIV-Positive Men in Washington State, 1996-2007.

Objectives: We assessed population-level trends in human immunodeficiency virus (HIV) and Neisseria gonorrhoeae co-infection among adult males in Washington State between 1996 and 2007.

Methods: Population-based categorical disease surveillance registries for gonorrhea and for HIV were electronically matched and merged at the record level and incidence rates were calculated for reported HIV-positive and presumed HIV-negative men.

Results: The incidence of gonorrhea infection increased significantly among both HIV-positive and presumed HIV-negative men from 1996 to 2005, and this trend has recently reversed for both groups.
