Ecological Change and Emerging Diseases

Ecological Change and Emerging Diseases

Ecological changes have increased the probability and severity of many diseases. Changes in the atmosphere, increased population densities, mobility and travel, toxins introduced into the nutrient cycles, the spread of still waters (reservoirs, ponds), the addition of drugs to the food web, megacities, and land use changes such as soil pollution and deforestation have all altered or added important vectors, hosts, and transmissions of disease. Dams, for instance, increase the transmission of water-related schistosomiases and malaria. Air conditioners can spread Legionnaire's disease. Reforestation can increase Lyme disease. Ozone-layer changes can increase cancers. The abusive use of DDT can produce pesticide-resistant malarial mosquitoes. Solutions may require global/local actions: heat waves, air pollution, and disease transmission by human migration (especially air travel) bring about new challenges to public health.
