Eliminating malaria — one of the world’s oldest and deadliest diseases — remains a critically important public health and biomedical research challenge. Despite remarkable advances in reducing malaria incidence and deaths since 2000, recent progress has become stagnant and has even reversed in some regions.

The World Health Organization (link is external) (WHO) estimates that in 2017 about 219 million cases of malaria occurred worldwide and approximately 435,000 people died of the disease. Unfortunately, malaria cases increased from 2016 to 2017 in the 10 highest-burden countries in Africa, and the number of cases per 1,000 in populations at risk remained at 59 from 2015 to 2017.
