COVID-19: Brookings Thresholds

UPDATED: May 7, 2021

  1. Is the epidemic controlled? Yes.  Rt was below 1.0 for 0 of the last 14 days; community spread is currently substantial per DOH definition based on last two weeks of cases.
  2. Is the health system able to cope with a resurgence of COVID-19 cases that may arise after adapting some measures? Based on current census data, Brookings Health System feels they can handle the lowest of the anticipated numbers (n = 2).  However, staffing will be challenged, thereby limiting the ability to sustain care for the long-term, with the highest anticipated number (n = 5).
  3. Is the public health surveillance system able to detect and manage the cases and their contacts, and identify a resurgence of cases in Brookings?
    a. Mitigation Level: Yes, according to BHS data (includes sentinel testing, multiple tests on same person, non-county residents) and state data using tests done, but not unique people tested.
    b. Suppression Level: No, test positivity is 5% based on BHS data and for state data there is a range of 2% based on tests done to 15% based on unique individuals tested.
    c. Approximate Time to Receive Test Results: 1 to 2 days
    d. Percent of Brookings population aged 16 years or older that has received at least one vaccine as of 5/5/21: 47%
