Despite great progress made against HIV globally, the gains are not shared equally. The numbers are staggering. They show that teen girls and young women bear a greater risk than their male peers. Only by understanding the magnitude of the problem facing adolescent girls and young women can we accelerate the end of HIV as an epidemic. As a response, The Global Fund to Fight AIDS, Tuberculosis and Malaria has launched the 'HER' Initiative, which aims to reduce new HIV infections among adolescent girls and young women by 58 percent in 13 African countries, over the next 5 years.
