Climate Forecasting Systems Help Predict Malaria Risk in Africa
A recent study published in Nature shows that climate forecasts can help predict malaria epidemics many months in advance. These predictions can alert health service managers to changes in epidemic risk five months before the peak malaria season and four months earlier than predictions based on actual rainfall. The study appears in the February 2…
