Weather, stomach bugs and climate change: Refining the model

Monitoring extreme weather, such as periods of high temperature, is one way to predict the timing and intensity of infectious diseases like cryptosporidiosis, an intestinal disease that causes upset stomach and diarrhea. Two public health researchers have created a model that takes into account weather and other factors that affect the number of people who will fall ill during an outbreak. With this model they show that the risk of weather-sensitive diseases may increase with climate variability or even gradual climate change. Better understanding of the ways in which climate can affect disease will help researchers forecast infectious disease outbreaks and design early warning systems.
