Current status and trends of HIV/AIDS in Japan and the world

As of 2007, an estimated 33.2 million people are living with HIV infection in the world. In 2007 there were 2.5 million new HIV infections and 2.1 million AIDS deaths globally. The HIV/AIDS epidemics in the world continue to spread unequally and the responses to it raise increasingly complex issues as the patterns of HIV spread become more diverse within and across countries. The background of the recent epidemics is different in each region and country. Prevention and care must be adapted to reach migrant populations, especially in developed countries, and renewed safer sex campaigns targeted at particular subpopulation with risk behavior are needed in every country.
