Health Policy Watch (HPW) "This was the question posed to us recently by a young person from our Youth4Health network. Our answer, both simple and sad: the reasons are not medical. As we observe World AIDS Day on Sunday, 1 December, the biggest remaining hurdles in the fight against HIV/AIDS in our region, and indeed much of our world, are political. Restrictive and intolerant environments. Stigma, discrimination and even criminalization of HIV transmission. Inconsistent uptake of evidence-based and recommended interventions. Today we have all the medicines, tools and technologies to end AIDS."
