Very few doctors and clinics have been implementing screening guidelines. However, there are signs that things may be improving. When powerful data was released showing that reducing viral load reduces the likelihood of sexual transmission of HIV, policies changed. Large cities started recommending universal access to HIV treatment. They removed restrictions related to CD4 count which previously meant that individuals with HIV had to wait to start treatment.
This change could be a great boon to serodiscordant gay couples. Reducing an infected person's viral load is not only a very effective form of treatment, but it also helps keep their sexual partners safe from infection.
The discovery of this effect, known as " treatment as prevention " continues to reshape HIV policy in the U. It is also changing the way doctors and scientists look at HIV prevention around the world.

Still, remaining challenges continue to complicate HIV control efforts. Many people living with HIV or at risk for HIV infection do not have access to prevention, treatment, and care, and there is still no cure. HIV primarily affects those in their most productive years, and it not only affects the health of individuals, but also impacts households, communities, and the development and economic growth of nations.
Many of the countries hardest hit by HIV also face serious challenges due to other infectious diseases, food insecurity, and additional global health and development problems. Sub-Saharan Africa, 10 with more than two-thirds of all people living with HIV globally, is the hardest hit region in the world, followed by Asia and the Pacific see Table 1. Numerous prevention interventions exist to combat HIV, and new tools such as vaccines, are currently being researched.
HIV treatment includes the use of combination antiretroviral therapy ART to attack the virus itself, and medications to prevent and treat the many opportunistic infections that can occur when the immune system is compromised by HIV.
In light of recent research findings, WHO released a guideline in recommending starting HIV treatment earlier in the course of illness. Over time, new initiatives and financing mechanisms have helped increase attention to HIV and contributed to efforts to achieve global goals; these include:. The contributions of affected country governments and civil society have also been critical to the response. At the June U. Secretary-General emphasized these commitments, calling for the global community to reinvigorate global efforts to respond to AIDS.
