In the last of a series of posts on the U.K. Department for International Development’s (DfID) blog examining the department’s work in Malawi, Neil Squires, DfID head of profession for health, looks at the sustainability of the country’s HIV/AIDS program. “Malawi’s success in increasing access to antiretroviral drugs for HIV is highly dependent on donor funding for medicines,” he writes, adding, “Malawi has to actively consider its resource allocation in order to maximize the benefits and the health gained from the limited resources available.” He notes a report commissioned by UNAIDS on Malawi concluded that “unless Malawi can reduce the incidence of new infections, the scale up in access to antiretroviral drugs will not be sustainable in the medium to long term.” He concludes, “This is an important issue for the Government of Malawi, but also for the key donors who have supported the massive scale up in access to drugs, particularly the Global Fund. Malawi will need to maintain high levels of funding from the Global Fund if it is to maintain its supply of antiretroviral drugs” (10/23).
