Eastern Europe and Central Asia have the world’s fastest-growing HIV epidemic, IPS reports. New HIV cases have risen 22 percent in the region since 2005, according to the World Health Organization. The WHO estimated about 170,000 new infections last year in the region, and advocates said the epidemic there is concentrated mostly among injection drug users. Experts blame punitive drug policies, discrimination and trouble accessing treatment. They say the situation will not be contained until local governments affected by the epidemic change their AIDS policies.
