description: Active encounters where the encounter diagnosis is suspected or confirmed COVID-19, or a Condition of confirmed COVID-19 was created during that encounter. This includes the patients with laboratory-confirmed or clinically diagnosed COVID-19.

Criteria

-	Description	Name	Language	Expression
*	This expression finds encounters that were active or finished in the reporting period, and their referenced Patient, Condition and Observation resources. It filters these based on cases where Encounter reports a reason or condition in the ConfirmedCOVID19Diagnoses value set, or where a positive lab test from the Covid19Labs valueset, or where the patient has any such associated Condition or Observation resources in the prior two weeks.	ConfirmedC19Pats	text/fhirpath	findAll('Encounter', including('subject','condition','reasonReference'), with('status').equalTo('in-progress,finished'), with('date').within(%ReportingPeriod) ).onServers(%Base). where( iif( (Encounter.reasonCode | Condition.code).member0f(%ConfirmedCOVID19Diagnoses.url) | Observation.where(code.member0f(%Covid19Labs.url) and value.member0f(%PositiveResults.url)), true, iif( Patient.distinct() .whereExists('Observation', for('patient', $this.id), with('status').equalTo( 'registered,preliminary,final,amended,corrected'), with('date').greaterThan(%ReportingPeriod.start - 1 'year'), with('code').in(%Covid19Labs), with('value-concept').in(%PositiveResults) ).onServers(%Base), true, Patient.distinct() .whereExists('Condition', for('patient', $this.id), with('verification-status').notEqualTo('refuted,entered-in-error'). with('date').greaterThan(%ReportingPeriod.start - 1 'year'), with('code').in(%ConfirmedCOVID19Diagnoses.url) ).onServers(%Base) ) ) ) .ofType(Encounter) .distinct() .aggregate( iif($total.subject contains $this.subject, $total, $total | $this ) )
