Maryland Department of Health Launches New Weather-Related Illness Data Dashboard

Baltimore, MD — As Maryland officially enters the 2026 heat season, the Maryland Department of Health has launched a Maryland Weather-Related Illnes​s Data Dashboard to provide a weekly snapshot of health data during the heat and cold seasons in Maryland.

The new dashboard, which replaces document-formatted reports, allows users to view and analyze data collected by the Department’s Office of Preparedness and Response on illnesses related to the state’s heat season (May through September), as well as its cold season (November through March). The dashboard is updated every Wednesday with data on emergency department (ED) visits, emergency medical services (EMS) calls and weather-related deaths. 

“We are seeing more extremes in weather in our state,” said Maryland Health Secretary Dr. Meena Seshamani. “The Weather-Related Illness Data Dashboard will help the Department and partner agencies support at-risk communities faster, allocate resources better, and monitor local needs during extreme heat and cold.”

The Weather-Related Illness Data Dashboard provides a comprehensive set of features, including:

Emergency Department and Emergency Medical Services Data:

  • Trends in Emergency Department visits for illnesses related to hypothermia and hyperthermia.
  • Trends in Emergency Department visits for unintentional carbon monoxide-related exposures during the cold season.
  • Trends in Emergency Medical Services calls for weather-related illness.
Illness Trends and Demographics:

  • Graphs illustrating hypo- and hyperthermia-related visits by week or season.
  • Detailed graphs for hypo- and hyperthermia-related visits, segmented by demographics (age group, sex, race/ethnicity) and geographic jurisdiction.
Weather-Related Death Data (Office of the Chief Medical Examiner Reports):

  • Graphs tracking weather-related deaths.
  • Analysis of conditions co-occurring with hypo/hyperthermia among weather-related deaths.
  • Data on the housing status of decedents from weather-related deaths.
  • Weekly trends for the date of death.
