These frequencies will not necessarily involve medical calls or ambulances, but instead will be government agencies providing supplies or personnel to assist with food and equipment as needed.
Many National Guard units have access to statewide radio systems, either trunked or conventional.
For those who are interested, I thought I would post what I have found and add to it as new information comes in.
If you have any frequencies or information on COVID-19 response frequencies, feel free to send them to me on Twitter (@TheFedFiles) or email cparris2+fedfiles@gmail.com
