Emergency Preparedness & Mercer County Medical Reserve Corps
Mercer County Health Department has an all-hazards Emergency Preparedness program with plans for responding to bioterrorism events, pandemic influenza, and other types of emergency situations. The Mercer County Health Department Emergency Preparedness Partners include members from Mercer County Emergency Management Agency, area law enforcement agencies, EMS responders, healthcare facilities, public health officials, veterinarians, senior living facilities, and local government officials.  The Emergency Preparedness Program also manages the Mercer County Shelter Program which helps coordinate shelter activation, resource requests, and training countywide.  For more information on the Mercer County Emergency Preparedness Program, call the health department at (309)582-3759, or email

The program works closely with Mercer County Medical Reserve Corps volunteers.  The group is comprised of people with medical backgrounds, area business owners, and public officials, as well as everyday citizens of our community.  These volunteers take part in many types of preparedness training including weather spotting, psychological first aid, support during mass medical dispensing, shelter operations, and care for those with special needs to name a few.  In the past, they have volunteered to act as "victims" during training events for our emergency responders.  New recruits are always welcome.  For more information about MRC, call the health department at (309)582-3759, see the Mercer County Medical Reserve Corps Facebook page, or e-mail
