By Katherine Hughes Malaria is spread by the mosquito Anopheles gambiae.
Analyses show malaria outbreaks outside tropical regions becoming more common in the future.
Climatic changes related to global warming could foster dangerous outbreaks of cholera, dengue fever and malaria, according to a report released recently by World Wildlife Fund. Children and the elderly would be particularly vulnerable. Climate experts and environmental officials from 180 countries are currently meeting in Buenos Aires, Argentina, to agree on a work plan for implementation of the 1997 Kyoto protocol, signed by developed countries in Japan last December. The WWF report was issued on the first day of the conference. According to the report, the spread of infectious diseases has accelerated not only because the world is warming, but because nighttime temperatures are rising faster than daytime temperatures.
