Background: Genital herpes is one of the most common sexually transmitted diseases. As a leading cause of genital ulceration, herpes genitalis plays a role in facilitating the transmission of HIV. Although HIV infection is most prevalent in Cameroon, information is lacking about prevalence of herpes simplex virus (HSV) type 2 infection in this country. Goal: The goal was to determine the prevalence of HSV-2-specific antibody in blood specimens from individuals in Cameroon. Study Design: Blood specimens were randomly collected from 410 clinic attendees (215 males, 195 females) in Douala, the most populous city in Cameroon. One hundred fifteen of the individuals (28.0%) were HIV-infected. Samples were tested by a type-common HSV IgG enzyme immunoassay not discriminating between HSV-1 and HSV-2 antibodies and by two glycoprotein G-2-based enzyme immunoassays for detection of HSV-2-specific antibody. Results: All but three blood samples were positive for type-common HSV IgG antibodies. Sixty-seven specimens (16.3%) were concordantly negative for HSV-2 antibody by both assays, and 287 (70.0%) specimens were concordantly positive. Fifty-six specimens (13.7%) yielded discrepant results between the two assays. Conclusion: On the basis of specimens with concordantly positive results, the overall HSV-2 seroprevalence was 70.0%. HSV-2 seroprevalence was significantly higher among HIV-infected individuals than among HIV-negative ones. Because of the serious morbidity and mortality caused by HSV-2, effective programs are needed to halt the spread of HSV-2 infection in Cameroon.
