The CSTE Executive Board unanimously approved position statement Interim-20-ID-02 for COVID-19 on August 5, 2020 (superseding Interim-20-ID-01). Key updates to the standardized case definition for COVID-19, include:

  • Clarifications to clinical, laboratory, epidemiologic linkage, and vital records criteria for case identification and classification,
  • Updated probable case classifications to classify the detection of SARS-CoV-2 antigen as a probable case, and
  • New suspect case classifications that are intended solely for internal health department surveillance tracking purposes and not for official case counts at the state, local, or national level.

“CSTE works to advance public health policy and increase epidemiologic capacity. We also provide information, education, training, and developmental support of practicing epidemiologists in a range of areas, as well as expertise for program and surveillance efforts.”
