12 182 HIV The Impact of Pre-exposure Prophylaxis on HIV Infection Control Ming-Shen Lin, Wei-Lun Chang, Shu-Hui Sun Department of Pharmacy, Far Eastern Memorial Hospital, New Taipei, Taiwan The mortality associated with human immunodeficiency virus infection has declined with current treatment and public health policy. For better disease control, UNAIDS established a new strategy on HIV management and a new, ambitious treatment target. Achieving these targets by 2020 will potentially end the AIDS epidemic by 2030, which in turn will generate profound health and economic benefits. Although many strategies had been implemented to achieve these targets, further interventions are required. Pre-exposure Prophylaxis (PrEP) is key to promote current strategies. Current clinical trials indicate that PrEP offers great protection from HIV infection depending on various populations. But sadly, no strategy is perfect. PrEP with poor adherence provides not only poor protection but also potentially increase resistant mutations. For this reason, we need further education and support policy to enhance patient s adherence. PrEP is definitely a landmark for HIV infection control. It requires more support from different sectors to make it better. It also needs more empathy and tolerance given from others. I believe that we can bring us closer to the goal of zero HIV infection in the future. Key words: Human immunodeficiency virus (HIV), highly active antiretroviral therapy, HAART, Pre-exposure Prophylaxis (PrEP), tenofovir disoproxil/emtricitabine (TDF/FTC), acquired immune deficiency syndrome (AIDS)
