Calling all first responders! If you are a member of a first responder organization responding to COVID-19 (including law enforcement, fire departments, and emergency medical services), please take a moment to complete this short questionnaire (about 6-8 minutes). A few minutes of your time now can help first responders facing pandemics in the future. This research is part of a larger study funded by the Department of Homeland Security’s Science and Technology Directorate to measure the impact of COVID-19, identify best practices organizations can put in place to protect themselves in the short term, and identify strategies to make first responder organizations more resilient.
