Description:
The spread of chronic and infectious diseases is a serious threat to public health. Research has shown that many chronic and infectious diseases are related to environmental conditions. Organisms such as ticks and mosquitoes (called disease vectors) transport these diseases, and variability in rainfall and temperature has a major influence on the distribution and quantity of these pests. Recent outbreaks of West Nile Virus and other vector-borne diseases have illustrated the importance of having accurate and timely information to predict and respond to epidemics.
