Kenya's president has announced that fees will be removed for anti-retroviral drugs (ARVs), which combat the effects of Aids. Correspondents say the fees are one reason why only 60,000 of the 200,000 eligible Kenyans are taking ARVs. The UN has said Kenya is one of the few countries to reduce HIV prevalence, from 14% in 1997 to 4% today. But charities now say that a hunger crisis in parts of Kenya could hamper the effectiveness of ARV programmes.
