From the WHO’s “Malaria Elimination: A Field Manual for Low and Moderate Endemic Countries“:

“Malaria transmission is particularly difficult to interrupt in areas with efficient mosquito vectors, a long or year-round transmission season, poor state of overall development, marginalized populations and weak health systems with inadequate coverage of health services, as well as in areas with civil unrest, illegal cross-border movement, or areas that border high-burden neighboring countries and experience intense cross-border population movement. Each of these factors will reduce the feasibility of malaria elimination”

Shouldn’t this be completely obvious? They are describing every place where malaria is, outside a few exceptional cases at this point. The WHO is stating clearly that malaria elimination in Sub-Saharan Africa is absolutely impossible.
