LONDON, June 26: Seven countries in sub-Saharan Africa, the world’s worst-hit region in the global AIDS epidemic, have cut the number of new HIV infections in children by 50 percent since 2009, the United Nations AIDS program said on Tuesday. The dramatic reductions – in Botswana, Ethiopia, Ghana, Malawi, Namibia, South Africa and Zambia – mean tens of thousands more babies are now being born free of HIV, UNAIDS said in a report on its Global Plan to tackle the disease in around 20 of the worst affected countries.
