The easiest way to participate in the AZ HEROES study is to take part in the University of Arizona – State of Arizona COVID-19 Antibody Testing Initiative (ATI). It is also possible to join AZ HEROES if you have tested positive for COVID-19 through another lab-based serology test or a PCR (nasal swab or saliva) or antigen test.

1) To assess the incidence of asymptomatic and symptomatic re-infection in frontline workers in Arizona (healthcare personnel, first responders and other frontline and/or essential workers); and
2) To identify patterns of COVID-19 immunity over time in previously and newly infected individuals who test positive for COVID-19 antibodies.
COVID-19 is caused by infection with the SARS-CoV-2 virus. It is highly contagious and transmitted primarily through respiratory droplets. Those infected can experience serious illness and death, although some people will have no symptoms at all even though they can still transmit disease. Health care workers, first responders, frontline workers and other essential workers are all at increased risk for COVID-19, given their exposure to the public and/or coworkers through work. We need to learn more about COVID-19 risks in each of these groups. We also need to determine how long immunity to COVID-19 lasts, or in other words, when a person can become infected again after repeat exposure toSARS-CoV-2, and how severe repeat infection will be. This information is critical to being able to protect our workforce and to our understanding of this pandemic disease.
