  • Participants must have smartphone access or internet access 
  • All participants must have a mailing address and plan to reside in Arizona for 12 months following enrollment 

Exclusion Criteria 

  • Have received the COVID-19 Vaccine

  • Unable to conduct study activities in English or Spanish 

All study participants will undergo weekly surveillance and self-collect a respiratory sample for COVID-19, via nasal swab, throughout the duration of the study. This testing is needed to detect when study participants are infected with COVID-19. This applies to both participants that have been infected with COVID-19 prior to the study and participants who are newly infected with COVID-19.  

All study participants will also be tested for antibodies to COVID-19 at three points in the study, once upon entering and twice at later points within a nine-month period, via blood & serum samples. The reason for this is to understand the length of time for the antibody response to COVID-19. Participants who have tested positive, via nasal swab, with new COVID-19 infection will be tested for antibodies again.   

AZ HEROES is working in coordination with the statewide AZ COVID-19 Antibody Testing Initiative (ATI) conducted by the University of Arizona. The ATI is funded by the State of Arizona to provide COVID-19 serological testing of up to 250,000 Arizonans, including healthcare care personnel, first responders and essential workers statewide.
