If I were asked to guess a country where AIDS is exploding, China wouldn’t come immediately to mind, but it should. There was an 8.6% increase in the number of AIDS-related deaths in China last year; of those that were reported and/or acknowledged. The percentage of cases might appear low in a country with an enormous population, but the number of affected people is high: over 68,000 new cases of HIV/AIDS reported in the past year.
CNN provides an overview of the current situation in China, touching on the years that the government denied there was a problem and their current policies, in the article The price of blood: China faces HIV/AIDS epidemic.
For more information on the current state of global HIV/AIDS, the 2012 report from UNAIDS is full of interesting data and impressive infographics.
