A global initiative, formed to mobilise society in the fight against AIDS, tuberculosis and malaria, has launched a campaign to force countries to drop import taxes on treated mosquito nets in an attempt to control the malaria epidemic. The initiative aims to hold governments accountable to commitments made in the Abuja Declaration signed two years ago, in which African states promised to reduce the costs of mosquito nets and insecticides. South Africa is one of several countries which has yet to make good on its promises. Anso Thom reports.
