The McHenry County Department of Health (MCDH), along with the Illinois Department of Public Health (IDPH) and the Centers for Disease Control and Prevention (CDC), are closely monitoring information on COVID-19 (Coronavirus Disease 2019). MCDH continues to coordinate with local, regional, and state partners.

In an effort to provide the county with the most up to date guidance regarding COVID-19, we’ve developed the McHenry County Department of Health Resource Guide. This tool will provide guidance on seeking medical care along with recommendations on staying safe during this time. This tool is not designed to diagnose or treat COVID-19, but can assist you with more information about this new coronavirus. Visit the resource guide by selecting the image below.

Additional MCDH activities include:

  • Investigating positive cases and instructing patients on isolation
  • Providing guidance to household members/contacts regarding quarantine and how to monitor for symptoms
  • Working closely with hospitals, community organizations and McHenry County government entities to plan for ongoing needs in the emergency response to this new viral threat
  • Actively planning alternate housing for recovery of medically stable patients that need a safe place to stay to complete isolation or quarantine
  • Continuing to run needed MCDH services such as WIC, immunizations for children under 2, TB clinics and other programs to support our community
  • Sharing information with the public, partners and staff via email, website and social media.
