"With donor money to fight HIV and AIDS falling, spending in sub-Saharan Africa must be targeted to get the best results," Bjorn Lomborg, director of the Copenhagen Consensus Center, writes in the Guardian's "Poverty Matters" blog, noting, "Sub-Saharan Africa has 10 percent of the world's population but is home to 70 percent of those living with HIV and AIDS." He continues, "The problem is neither beaten nor going away: new infections continue to outpace the number of people put on treatment," and writes, "One of the biggest impediments to the fight is the incorrect perception in developed nations that the epidemic is beaten. Thanks to donor fatigue and tougher economic conditions, many donor countries have reduced their contributions significantly."
