The Urgency of Expanding Pre-Exposure Prophylaxis (PrEP) for Global HIV Reduction

Abstract

Globally, an estimated 76.1 million persons have become infected with HIV since the start of the epidemic, with 35 million having died from AIDS-related illnesses. In spite of 19.1 billion dollars spent annually in low- and middle-income countries, with most of those funds going toward the provision of antiretroviral medications, only 56.9 percent of all HIV-infected persons are receiving these medications.
