[HIV post exposure prophylaxis therapy - the experience of two major AIDS centers].

Background: During recent years, the use of antiretroviral therapy expanded beyond the treatment of HIV-infected patients. Since the outset of the HIV epidemic, antiretroviral drugs were also used for post-exposure prevention of HIV infection in health workers and implemented after possible exposure during sex. In this study, we summarize the cases from the AIDS center in the Kaplan Medical Center and the Sheba Medical Center after possible exposure to HIV (occupational or sexual).
