In recent decades, countries around the world have made great progress against malaria. However, a new report from the World Health Organization (WHO) says that progress is at risk. This WHO annual report looks at the global fight against the disease. It says that malaria cases are on the rise in several countries. Many countries are moving toward eliminating malaria, among them Madagascar, Senegal and Zimbabwe. However, the WHO report warns that in others, progress has stalled. Malaria cases increased by more than 20 percent from 2015 to 2016 in eight African countries, including Rwanda, Nigeria and the Democratic Republic of Congo. At the same time, funding for malaria prevention and treatment has leveled off, reaching $2.7 billion in 2016. This amount is less than half of the 2020 target.
