Nigeria has appointed Aliko Dangote, Africa’s richest man, to lead a committee commissioned with eliminating malaria in the West African nation as the mosquito-borne infection has made a comeback across the continent amid disruptions related to the coronavirus pandemic. Africa’s most populous nation, which also has the highest prevalence of malaria globally, can save 687 billion nairas (N$ 26 billion) this year, and 2 trillion nairas by 2030, if it were to put an end to the disease, President Muhammadu Buhari said on Tuesday.
