Join the Fight Against COVID-19 on Tribal Lands!


AZ HEROES (Arizona Healthcare, Emergency Response, and Other Essential Workers Surveillance) is a study at the University of Arizona (UA) that wants to understand essential workers’ health related to getting or re-getting COVID-19. In addition, this study plans to partner with Tribal Communities to include Native American participants to ensure adequate representation in the study.


The UA College of Public Health is looking for tribal members, who are essential workers, to join the AZ HEROES Study. 

Essential Workers in Tribal Communities include, but are not limited to:

  • First responders (emergency medical technicians, firefighters, emergency preparedness personnel)
  • Health care personnel (CNAs, RNs, pharmacy technicians, physicians, etc.)
  • Tribal office workers
  • Convenient and grocery store workers
  • Casino workers 
  • Educators not working remotely
