OP&R's Preparedness Surveillance & Epidemiology Team (PSET) conducts year-round surveillance on disease, weather-related illness and deaths across Maryland. This data is developed by our epidemiologists using the Maryland Department of Health's syndromic surveillance system, the Electronic Surveillance System for the Early Notification of Community-based Epidemics (ESSENCE).
SPECIAL NOTICE: The weekly Cold-Related Illness Surveillance Report, Heat-Related Illness Surveillance Report and Public Health Preparedness and Situational Awareness (PHPSA) Report have all been upgraded to interactive dashboards. This new format provides users with a more intuitive and engaging way to explore the data, providing users with real-time insights and customizable views. The new dashboards can be accessed by clicking the links below.
Data is gathered from November through March in collaboration with the Maryland Institute for Emergency Medical Services Systems (MIEMSS) and the Office of the Chief Medical Examiner. Updated every Wednesday, the data focuses on extreme cold conditions including temperature and wind chill, cold-related illness, and carbon monoxide exposure.
Data is gathered from May through September in collaboration with the Maryland Institute for Emergency Medical Services Systems (MIEMSS) and the Office of the Chief Medical Examiner. Updated every Wednesday, the report focuses on extreme heat conditions including temperature, heat index, and heat-related illness.
This data provides a snapshot of disease throughout Maryland. Information is gathered from local, state, national and international sources, looking for different types of illnesses or disease clusters which may warn of a larger public health issue, including the potential for a bioterrorism event.
