Fake drugs are one reason malaria still kills so many

Malaria, a mosquito-borne parasitic infection that affects about 3.2 billion people in 95 countries, has become largely a disease of the young and poor. Due to effective medications like chloroquine and artemisinins, malaria deaths dropped an estimated 60 percent worldwide between 2000 and 2015. The Americas and Africa saw the greatest improvements. Still, 216 million new cases of malaria were reported in 2016, the latest data available. Most of them occurred in Nigeria, the Democratic Republic of the Congo, Uganda, Ivory Coast and Mozambique. And of the 445,000 people who died from the infection, about 70 percent were children under the age of 5. If malaria is a curable disease with effective treatment, why does it still kill so many?
