Seroepidemiología del virus Herpes simplex 2 en una población indígena Yukpa. Estado Zulia. Venezuela
Background: Yukpa aborigines start early in life their sexual activity and promiscuity with native and foreign individuals is common among women. This behavior allows the installation and propagation of Herpes simplex virus type 2 (HSV-2). Aim: To determine the presence of antibodies to HSV-2 in a Yukpa Amerindian community at Zulia State, Venezuela. Subjects and methods: We studied 96 natives, between 13 and 49 years old (62.3% of the whole population, 100% of individuals in fertile age). Control population consisted of 76 individuals, with similar sex and age range distribution, of the urban population from Maracaibo, Zulia State, Venezuela. HSV-2 serologic status was determined by an indirect fluorescent antibody test. Results: Antibodies to HSV-2 were detected in 53.1% of Yukpa population and 21.1% of urban population. Aboriginal women aged 21 to 40 years old had a prevalence of antibodies against HSV-2 of 66.7%. Among pregnant native women, the prevalence of antibodies against HSV-2 was 54.6%. Conclusions: There is a high prevalence of antibodies against HSV-2 among Yukpa natives in Venezuela. (Rev Méd Chile 2001; 129: 247-52).
