BACKGROUND HIV Pre-Exposure Prophylaxis (PrEP) has been found to be efficacious in preventing HIV acquisition among seronegative individuals in a variety of risk groups, including men who have sex with men and people who inject drugs. To date, however, it remains unclear how socio-cultural norms (e.g., attitudes towards HIV; social understandings regarding HIV risk practices) may influence the ...
INTRODUCTION Antiretroviral treatment (ART) and pre-exposure prophylaxis (PrEP) have demonstrated efficacy as new human immunodeficiency virus-1 (HIV-1) prevention approaches for HIV-1 serodiscordant couples. METHODS Among Kenyan HIV-1 serodiscordant heterosexual couples participating in a clinical trial of PrEP, we conducted a cross-sectional study and used descriptive statistical methods to...
The aim of the present study was to evaluate the data on human exposure to potential rabies virus transmitters in Olinda, State of Pernambuco, Brazil. Data from 7,062 patients who underwent antirabies prophylactic treatment in Olinda between 2002 and 2006 were analyzed. As expected, dogs and cats were involved in most of the cases; i.e. 82.3 and 16.3%, respectively. Attacks by nonhuman primates...
Despite significant efforts, the rate of new HIV infections worldwide remains unacceptably high, highlighting the need for new HIV prevention strategies. HIV pre-exposure prophylaxis (PrEP) is a new approach that involves the ongoing use of antiretroviral medications by HIV-negative individuals to reduce the risk of HIV infection. The use of daily tenofovir/emtricitabine as oral PrEP was found ...
INTRODUCTION Studies examining the use of pre-exposure prophylaxis (PrEP) to prevent HIV transmission among people who inject drugs (PWIDs) have not been adequately summarized. Recently, the Bangkok Tenofovir Study has shown that PrEP may be effective at reducing new HIV infections among this high-risk group. This randomized controlled trial was the first study to specifically examine the effic...
Post-exposure prophylaxis (PEP) can be a secondary measure to prevent infection by human immunodeficiency virus (HIV) when primary prevention has failed. PEP is advised for people with sporadic and exceptional risk exposure to HIV. This consensus document about occupational and non-occupational PEP recommendations aims to be a technical document for healthcare professionals. Its main objective ...
Clinical trials have recently demonstrated the effectiveness of Pre-Exposure Prophylaxis (PrEP) in preventing HIV infection. Consequently, PrEP may soon be used for epidemic control. We model the dynamic interactions that will occur between treatment programs and potential PrEP interventions in resource-constrained countries. We determine the consequences for HIV transmission and drug resistanc...
Evaluating the impact of prioritization of antiretroviral pre-exposure prophylaxis in New York City.
OBJECTIVE: To compare the value and effectiveness of different prioritization strategies of pre-exposure prophylaxis (PrEP) in New York City (NYC). DESIGN: Mathematical modelling utilized as clinical trial is not feasible. METHODS: Using a model accounting for both sexual and parenteral transmission of HIV, we compare different prioritization strategies (PPS) for PrEP with two scenarios - n...
The HIV pandemic persists globally and travelers are at risk for infection by the Human Immunodeficiency Virus (HIV). While HIV-focused guidelines delineate risk stratification and mitigation strategies for people in their home communities, travel issues are not addressed. In this review, direct and indirect evidence on HIV risk among travelers is explored. The burgeoning practice of employing ...
