You asked: Where is malaria mostly found in Africa?

The highest transmission is found in Africa South of the Sahara and in parts of Oceania such as Papua New Guinea. In cooler regions, transmission will be less intense and more seasonal. There, P. vivax might be more prevalent because it is more tolerant of lower ambient temperatures.
