While a number of countries in southern Africa have made great strides in improving access to antiretroviral (ARV) treatment for HIV-infected adults, progress in rolling out treatment for HIV-positive infants and children has lagged behind. Namibia is a notable exception. Over 7,600 children are receiving ARV treatment - 100 percent of those estimated to be in need of the life-prolonging medicine - according to Dr Angela Mushavi of the US Centres for Disease Control and Prevention (CDC), a technical advisor to Namibia's prevention of mother-to-child HIV transmission (PMTCT) programme.
