Background: Herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) are common infections worldwide. HSV-2, in contrast to HSV-1, is usually sexually transmitted. In many localities prevalence estimates for HSV-1 and HSV-2 are not available. This study presents prevalence estimates for Los Angeles County (LAC) among participants aged 14-49 years.

Methods: Data from the 1999-2004 National Health and Nutrition Examination Survey (NHANES), a cross-sectional, nationally representative survey of the US civilian non-institutionalized population, were used in the analysis. Sample weights were recalculated for participants examined in Los Angles County (LAC) using population totals provided by the local Department of Public Health.

Results: Seroprevalence of HSV-1 in LAC was 64.6% (95% CI, 57.4%-71.4%). Age and race adjusted estimates were 50.6% (95% CI, 40.5%-60.7%) for LAC compared with 57.8% (95% CI, 56.1 %-59.5 %) for the US. Seroprevalence of HSV-2 in LAC was 21.9% (95% CI, 14.3 %-31.3 %). Age and race adjusted estimates were 24.4% (95% CI, 14.2 %-37.3%) for LAC compared with 17.3% (95% CI, 16.3 %-18.3 %) for the US. Seroprevalence for HSV-1 and HSV-2 was consistently higher among older participants (age 30-49 years), females, and those below poverty for both the US and LAC although statistical significance (p<0.05) was not always reached within the LAC sample.

Conclusion: Almost two-thirds of LAC residents were HSV-1 seropositive and one-fifth HSV-2 seropositive. No significant differences were found in either HSV-1 and HSV-2 seropositivity when comparing the LAC sample to the US and trends by age, gender and poverty were similar.
