Is it possible that global warming could make diseases stronger and spread more quickly?

    Yes. Climate limits how far many diseases can spread. In the U.S., a warmer climate and the heavy, extended rains it brought likely helped spread the hantavirus, a lung disease spread by carriers like deer mice. In other places, a warmer world is helping expand the ranges of insects that carry diseases like dengue and yellow fever. People who historically had little or no risk of getting these diseases could soon have to worry about them. Furthermore, in 2008 the World Health Organization (WHO) chief Margaret Chan said the reality of climate change “can no longer be doubted. The effects are already being felt.” She cited climate-sensitive diseases such as dengue and cholera, which are currently present in South America and Angola, respectively, because of flooding.
