I thought I answered your question. If you're looking for stats, check Wiki, Google, or the FrontPage of this Site. As I stated Africa remains ground zero for most if not all the Zoonosis of the 20th century, can I tell you how many have died from Ebola, Malaria, Hantavirus, Bird Flu, how many may die from this Swine Flu? No! However, the source/cause (Factory Farming) of this most recent viral scare might spare the less industrialized nations in Africa. It is no surprise that Bird Flu was of greater threat to the Egyptian Nation compared to other Nations on the continent. Cause and Consequences. One might consider AIDS as the most deadly Zoonoses, if one does not buy the argument that the actual mutation was engineered in a lab and then transmitted to the human population.
