The good news: The number of people who die of malaria has been halved since 2000.
The bad news: The disease infected almost 200 million people and killed an estimated 548,000 last year.
The global fight against malaria has reached a critical phase, with the number of deaths from the disease falling by almost half since the turn of the millennium. But a third of households in sub-Saharan Africa still lack a treated mosquito net and dozens of countries are reporting insecticide resistance.
Between 2000-13, the worldwide malaria mortality rate decreased by 47%, and by 54% in Africa – where about 90% of malaria deaths occur. Children under five are particularly vulnerable, accounting for 78% of deaths.
Analysis by the WHO suggests that in sub-Saharan Africa, where there has been a 43% population increase, fewer people are becoming infected each year, with the number dropping from 173 million in 2000 to 128 million last year.
