Procurement and supply chain management is a key element of successful transitions. The procurement of affordable and quality medicines for prevention, treatment and care of patients is at the core of national HIV / AIDS, malaria and TB programmes. However, transitioned countries with small caseloads of patients sometimes lose timely access to quality prevention tools, diagnostics and treatments at affordable prices, as their orders are considered too small by major pharma companies to raise commercial interest, thus putting transitions at risk. To prevent such difficulties, the Global Fund has recently piloted access to wambo.org (an online platform that allows eligible countries to purchase quality-assured medicines and medical products at negotiated prices) to transitioned countries.
