Providing antiretrovirals (ARVs) to all people with HIV worldwide who qualify for the meds would cost an additional $6 billion annually, bringing the yearly total to at least $22 billion, according to the United Nations and reported by Bloomberg News. The World Health Organization (WHO) recommends that HIV-positive people begin taking ARVs when their CD4 counts drop to 350 or below. About 34 million people have HIV globally. Only about 6 million people currently receive ARVs, but 15 million qualify for them under WHO guidelines. World leaders recently committed to the proposed increase: to boost funding from $16 billion a year to at least $22 billion a year by 2015. This would expand treatment to all 15 million people. But in today's economic climate, it remains to be seen whether the money and meds will materialize.
