Healthcare providers are particularly requested to promptly report and submit nasopharyngeal specimens to OCHCA for possible whole genome sequencing from any individuals with SARS-CoV-2 virus infection who meet any of the following criteria:

  • All patients hospitalized with SARS-CoV-2 infection
  • All cases associated with congregate living settings such as skilled nursing facilities and homeless shelters
  • Cases associated with unusual circumstances such as large outbreaks
