The feet of HIV-infected Raphael Mbuzi, 51, are seen in Chilanga Mother of Mercy Hospice in Lusaka November 25, 2006. Mbuzi is suffering from a form of cancer symptomatic of HIV infection on his legs. Surveillance for the HIV virus is weak in most of the world and prevention and treatment programmes often fail to reach high-risk drug users, homosexuals and sex workers, the World Health Organisation said on Friday. In a message marking World AIDS Day, being celebrated under the theme of Accountability, the WHO's acting director-general Anders Nordstrom said that tackling the AIDS epidemic remained one of the world's most pressing public health challenges. Only 1.6 million people or 24 percent of the 6.8 million people worldwide who need the life-extending therapy receive it, according to the latest joint report of UNAIDS and the WHO.
