Infectious Disease
Global warming is likely to increase the risk of some infectious diseases because rising temperatures and increased rainfall benefit insects and animals that carry human disease. Mosquitoes, for example, reproduce more rapidly and transmit disease more efficiently at higher temperatures. Warming temperatures also may allow mosquitoes and other insects to expand their range, which could put previously unexposed populations at risk of infection. More complex is the relationship between rainfall and disease transmission. Increasing frequency and intensity of droughts and floods, and more rapid swings between the two extremes could worsen the spread of disease. The mosquito that carries West Nile virus, for example, thrives in drought conditions, while the populations of its predators are reduced. Since it was introduced to North America just seven years ago, West Nile virus has infected more than 21,000 people in the United States and Canada. Lyme disease, malaria, dengue fever, yellow fever, and encephalitis could also spread as a result of global warming. Developing countries, which already experience a disproportionate share of the global infectious disease burden, are especially at risk.
