Public Health Emergency Preparedness

Public Health Emergency Preparedness (PHEP) is responsible for developing response plans to be used in the event of an incident that threatens the health of Mariposa County residents. Through planning, exercises, community education, and training, PHEP ensures that the county’s first responders and health care system prepare, respond and recover from public health emergencies in an effective manner. To do this, PHEP coordinates with agencies such as John C Fremont Hospital District, the Mariposa County Office of Emergency Services (OES), Mercy Medical Transportation, Mountain Valley EMS, as well as other county agencies and organizations.

Some examples of public health emergencies are:

Wildfire; infectious disease outbreak, such as the 2010 pandemic flu; prolonged power outages; biological terrorist attacks such as an anthrax release; chemical spills such as chlorine gas; severe weather such as extreme heat or cold; and natural disasters such as earthquake and floods.
