For survival, the V. Cholerae need an optimum temperature and physicochemical circumstances (salinity, pH, humidity etc.) This blog is a part of a new series from Climate Reality on the many ways that climate change is impacting human health. Climate change may affect zoonoses (infectious diseases of animal origin that may be transmitted to humans) in 3 ways: it may increase the range or abundance of animal reservoirs or insect vectors, prolong transmission cycles, or increase the importation of vectors or animal reservoirs (e.g., by boat or air) to new regions, which may cause the establishment . Many disease-causing organisms are strongly influenced by environmental factors such as temperature, rainfall and humidity, which are in turn influenced by climate change. As one example, pregnant women are more vulnerable to Zika. Changes in humidity can lead to an increased risk of illnesses that spread through bodily fluids. Some existing health threats will intensify and new health threats will emerge. 7 Of this increase, 60,000 deaths/year will be . The distribution of several infectious diseases, including malaria, tick-borne diseases, and food- and water-borne diseases, is directly related to local environmental conditions. As another example, according to the WHO, the spread of disease due to climate change will result in 48,000 additional deaths from diarrhea for children under 15 years and 60,000 from malaria by 2030. Historic Perceptions of . For this reason it is widely expected that climate change will affect infectious disease patterns.
