The Office of Preparedness and Response develops regular reports with information about disease, weather-related illness, or deaths across Maryland.​ These reports are largely 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).

This weekly report is provided from November through March. Data is gathered in collaboration with the Maryland Institute for Emergency Medical Services Systems (MIEMSS) and the Office of the Chief Medical Examiner. The report focuses on extreme cold conditions including temperature and wind chill, cold-related illness, and carbon monoxide exposure. 

This weekly report is provided from May through September. Data is gathered in collaboration with the Maryland Institute for Emergency Medical Services Systems (MIEMSS) and the Office of the Chief Medical Examiner. The report focuses on extreme heat conditions including temperature, heat index, and heat-related illness.
