Climate/Weather

Climate change, including major changes in temperature, sea level rise, and rainfall, can impact our health in many ways. Extreme weather like floods, droughts, and major storms can lead to:
- injury
- illness
- displacement of people
- worsening of chronic illness
More wildfires, smog, pollen, and mold can lead to asthma and allergy attacks.
More extreme heat outside can put you at risk for:
- dehydration
- heat cramps
- heat stroke, and even death.
Longer warm seasons and precipitation changes can lead to more vector-borne disease.
All communities can feel the effects of changes in our climate. Some people are affected by those changes more than others.
Who is at higher risk?
- Outdoor workers
- Infants and young children
- Pregnant women
- People aged 65 and over
- Those without access to air conditioning or heat
- People with chronic conditions including asthma, heart disease, and diabetes
Paying close attention to weather forecasts can help you plan. News reports can be a resource for shelters or evacuation information. Whenever possible, have a plan before conditions become severe.
Virginia EPHT provides data about heat in Virginia. You can explore:
- Number of extreme heat days each year
- Number of heat events each year
- HeatRisk forecast
- Cooling Center map tool
VDH also tracks visits to emergency departments and urgent care centers to help protect public health. VDH uses a system called ESSENCE to monitor these trends. From May through September, the Office of Epidemiology tracks heat-related illness. For data on heat-related emergency department visits, see Heat-Related Illness Surveillance.
VDH also shares data about heat-related incidents reported by Emergency Medical Services (EMS). These incidents include people who receive care from paramedics or other EMS responders. For heat-related EMS data, see Heat-Related Illness Incidents.
