Heat can cause serious illness. On very hot days, sometimes your body temperature can get dangerously high. This makes you at greater risk for serious heat illnesses.

Climate Change

In the past 50 years, Vermont's climate has been getting warmer and wetter. In the future, Vermont will continue to get warmer and experience more frequent heavy precipitation events.

Climate Change and Waterborne and Foodborne Diseases

Heavy rains can wash contaminants into drinking, recreational and irrigation waters that can make people sick. Harmful contaminants include human and animal waste, industrial chemicals, oil and other fuels, pesticides and fertilizers. Heavy rains can also result in overflows of combined sewer systems, which are designed to treat both stormwater and wastewater at the same time. During heavy rains, there may not be enough capacity in the system, leading to the discharge of untreated or partially treated wastewater. Flooding can make all of these problems even worse.

Climate Change and Mosquito-Borne Diseases

Mosquitoes can be a major annoyance during warmer months in Vermont and can occasionally transmit serious diseases. West Nile Virus (WNV) has been detected in every county of Vermont and typically infects three or fewer Vermonters each year. Eastern Equine Encephalitis (EEE) has also been detected in Vermont and caused two deaths in Rutland County in 2011.

Climate change is expected to affect mosquito-borne diseases in two ways:

Climate Change and Tickborne Diseases

The spread of tickborne diseases to humans, including Lyme disease and anaplasmosis, has been increasing in Vermont and many other northern states.
