What are the statistics of malaria in South Africa from 2002-2011 for males and females?
It is difficult to find statistics across time that are detailed enough to distinguish between the sexes. However, I have found a website collates information about malaria in southern Africa specifically, and this link will take you to a figure on that site which shows the number of cases for three regions of South Africa for almost the last 20 years: Malaria in Southern Africa.
Another source to look at is the World Health Organisation World Malaria Report from 2011, which for the first time, presented information on malaria cases and deaths from 99 individual countries. The website for that report, which can be freely downloaded can be accessed via this link: WHO World Malaria Report 2011.
