Malaria transmission requires the presence of Anopheles mosquitoes; as such, conditions which favor the growth and persistence of these mosquitoes will also be hotspots for malaria transmission, provided the climate is also sufficiently warm for the development of the parasite within the mosquito. Contributing Factors and Foodborne Disease The health burden posed by foodborne dis-ease is significant. The time to illness may vary depending on many things such as the host’s overall fitness and age, the amount and serotype of Salmonella ingested (with some serotypes as few as 20 cells), and the presence of various “stress” factors such as whether the person is undernourished, etc. The best known examples are sexually transmitted diseases, and the ways in which such human behavior as sex or intravenous drug use have contributed to the emergence of HIV are now well known.
