What are the worldwide trends in the HIV/AIDS epidemic?
2.1 At the end of 2005, about 38.6 (32*) million people were living with HIV worldwide. That year, 4.1 (2.9*) million became newly infected and 2.8 (2.2*) million died because of AIDS, so the overall number of people living with HIV has continued to rise. Today, about one adult in a hundred is living with HIV, but the extent of the epidemic varies greatly across countries and regions. More… Note: The 2008 Report on Global AIDS epidemic by UNAIDS/WHO provides better estimates of the number of people living with AIDS. Better data collecting and estimation methods led to revised figures : the total estimated number of people living with AIDS at the end of 2007 is 33.2 millions, with 2.5 million new infections and 2.1 million deaths (see the 2008 UNAIDS report ). This decrease from previous numbers does not represent a trend in the epidemic, which is still progressing, but a refinement in the data. For example, the new estimate puts the number of people that were living with AIDS in 2005
