The ongoing Ebola epidemic in parts of West Africa largely overwhelmed health-care systems in 2014, making adequate care for malaria impossible and threatening the gains in malaria control achieved over the past decade.

Mass drug administration can be an effective means to mitigate this burden and reduce the number of non-Ebola fever cases within health systems Open Access through Wellcome Trust
