ABSTRACT

OBJECTIVE@#To understand the associated factors on human immunodeficiency virus (HIV) transmission via heterosexual contact and to provide evidence for decision-maker for prevention of HIV.
@*METHODS@#Questionnaire survey was conducted in 250 HIV-positive persons to understand their socio-demographic characteristics and sexual behavior. Meanwhile, 431 persons who had heterosexual contact with the HIV carriers were traced to their HIV infection status. The factors associated with continued HIV transmission were reviewed by case-control analysis.
@*RESULTS@#Among the 432 persons, 59 were HIV-positive because of heterosexual contact. The secondary attack rate and the growth rate was 13.7% (59/431) and 0.236 (59/250), respectively. The factors associated with the spread of HIV included the degree of knowledge on HIV/AIDS, psychological reflection after infection, the condition for condom usage among spouses, and regular sexual partners or non regular sexual partners.
@*CONCLUSION@#The secondary attack rate and the growth rate of HIV transmission by heterosexual contact are high. Improvement of the knowledge about HIV/AIDS prevention and control, enhancement of psychological education and promotion of condom usage can reduce the risk for continued HIV transmission.
