Really Weedpacket?? I hope you are joking!! 😕
The straight answer to your question is YES, malaria is a serious drain on resources. Those that it does not kill are debilitated by it periodically, unable to work and in need of care, and a serious drain on their families' and communities' resources.
I might also add that it is not population size that causes all the poverty and famine in Africa. It is BAD POLITICS: corruption at all levels, ethnic frictions, lack of infrastructure and organisation, interferance by the World Bank et al, exploitation by global corporations, and unfair trade practices by the developed nations that are at the root of the problem.
