This study examines the association between Internet use and (1) the number of close ties (people with whom a person is closely acquainted), and (2) the percentage of HIV-positive individuals in the personal network of people living with HIV/AIDS (PLHA) in an urban area of Peru. Ninety-four PLHA responded to a survey; 72% were male, and the average age was 36.65 (SD = 7.92). Internet use was not associated with the number of close ties or with a greater number of close ties who are HIV-positive in one's personal network. Internet use was higher among those with greater than a high school education and females reported more social ties than males. © Springer Science+Business Media, LLC 2009.
