The environmental epidemiologist investigates vector born infectious diseases (i.e., rabies, mosquito-borne encephalitis, Lyme disease, etc.) as a means of monitoring trends, identifying factors influencing exposure, and determining optimal control measures. Field investigations are conducted as necessary to identify the source of disease and the appropriate measures to interrupt disease transmission. More recently, the scope of investigation has been expanded to include non-occupational environmental exposures to physical and chemical agents that have adverse health effects. Of particular interest are illness or conditions resulting from exposure to air or water containing toxic or carcinogenic agents. This includes assessment of reported cancer clusters with special assistance from the Iowa Health Registry, University of Iowa.
