Four medical practitioners from the United States and a local doctor have been in police custody for three days in Zimbabwe for allegedly distributing AIDS medication illegally, dpa quoted officials and lawyers as saying on Sunday. The Americans - a doctor, two nurses and a community volunteer - are affiliated with a US Baptist church in Oakland, California. They are due to appear in court on Monday, according to their lawyer, Jonathan Samkange. A US embassy statement said they were arrested on suspicion of distributing antiretroviral (ARV) drugs without a licence. Consular officials have been in regular contact with the group. It is receiving adequate treatment from police, the embassy said. The Zimbabwean doctor is a senior physician based at a hospital 80 kilometres east of Harare. About 13 percent of Zimbabweans are infected with the HIV virus, which kills 1,030 people a week, according to official figures. The state health service, still struggling to recover from the 2008 economic collapse, can supply ARVs to only a small portion of those infected with AIDS, thus relying on local and foreign non- governmental organisations to meet the bulk of demand. The group was arrested at the Harare offices of the Zimbabwe AIDS Network, an umbrella organisation of groups working to contain the HIV-AIDS epidemic. They were not only involved in the distribution of ARVs, but also worked with AIDS orphans, the embassy statement said. Zimbabwe law requires that foreign-registered medical personnel obtain a certificate to practise medicine in Zimbabwe from the local medical association.
