What’s the difference of malaria deaths between the subtropical and tropical regions and all the other regions?
I am assuming you are asking about the distribution of deaths caused by malaria between the tropics/sub-tropics and the rest of the world.
95% percent of all fatal malaria cases occur in sub-Saharan Africa, which lies entirely in the sub-tropics and tropics. Additionally, most of the deaths occur in Central, West and Eastern Africa (North Africa and South Africa have more advanced malaria prevention and control initiatives to the rest of the continent, and transmission is also less severe), and the other 5% of malaria deaths are mostly found in India and south-east Asia, so you could say that virtually all deaths due to malaria occur in tropical regions alone.
Indeed, there is almost no malaria in non-tropical or sub-tropical regions; the few cases each year in North America and Europe are usually due to imported cases from people who have traveled to tropical or sub-tropical regions.
