CASES study:  COVID-19 Arapahoe SErosurveillance Study

What is the CASES Project?

The COVID-19 Arapahoe SErosurveillance Study (CASES) project aims to measure exposure to SARS-CoV-2, the virus that causes the disease called COVID-19, in Arapahoe County. The CASES project will be split into two phases. During phase 1 we will test Arapahoe County first responders (firefighters, emergency personnel, police officers, etc.) for history of SARS-CoV-2 infection through blood tests to measure antibodies to the virus. During phase 2 we will expand our testing to the Arapahoe County community. The objectives of phase 1 of the CASES project are to:

  1. Determine a baseline prevalence (the percent of people who were infected with the virus) of the novel coronavirus (SARS-CoV-2) antibodies among first responders in Arapahoe County.
  2. Determine if there is a change in prevalence of SARS-CoV-2 antibodies among this same population after the transition to the safer-at-home policy.
  3. Compare venous blood draw methods to finger prick methods for detection of antibodies to SARS-CoV-2.
