Public Health & Epidemiology

Findings

Catalogue-native findings must describe the information grouped by each layer. This legacy version does not declare them separately.

Questions & artifacts

Questions, artifact requirements and serial naming rules are required by Vercy vNext; they remain unassigned in this reference version.

Dimension & namespace

• COMPOSE `world.personalHealth` (B10): consented or legally mandated notifiable facts arrive de-identified and are composed into cohort aggregates; the person-grain record never crosses into this model
• MIX-IN `world.statisticalDisclosure` (S5): cohort-grain aggregation, minimum cell sizes and suppression rules applied to every published series
• COMPOSE `world.eventRegister` (R3): surveillance series and outbreak timelines are kept as append-only event logs
• REFERENCE `world.attestationCertificateAndLicense` (R5): immunization certificates exist at person grain in R5/B10 and are only counted here at cohort grain
• REFERENCE `world.identityRegister` (R4): reporting institutions, not persons, resolve to anchored identities
• imports: who-icd (REFERENCE): condition classification as an externally governed code scheme
• imports: hl7-fhir (ALIGN): alignment of case and immunization semantics with clinical resource definitions
• imports: who-ihr (ALIGN): international notification obligations and event assessment vocabulary

Artifact formats & serial data

Format-independent core. Concrete artifact formats and naming prefixes are not declared in this legacy version.

Policies & accepted processes

• `notificationIntakeContract`: terms under which care providers submit notifiable reports, de-identified at intake
• `researchAccessContract`: cohort-grain access for accredited researchers under disclosure control
• `publicDashboardContract`: open publication terms for aggregate indicators
• `internationalReportingContract`: notification of qualifying events to international health bodies

Read / add / edit / delete

CRUD procedures and interface bindings are not declared in this legacy version.

Ownership, roles & access

The public health authority owns the surveillance series, outbreak records and measures, at cohort grain only: this model never holds person-grain data, and the S5 disclosure rules are part of its published shape. Access beyond open dashboards is granted via the S1/S2 access and consent models and audited via S4.

Objects

• `populationHealthIndicator`: one tracked series; key attributes: indicatorCode, cohortDefinition, area, cadence
• `notifiableCaseReport`: a de-identified report of a notifiable condition; key attributes: conditionCode, cohortBand, area, reportedAt, reporterClass
• `healthSignal`: an anomaly raised from surveillance; key attributes: source, detectedAt, severityGrade, status
• `outbreak`: a declared episode of elevated activity; key attributes: conditionCode, declaredAt, affectedArea, phase, closedAt
• `transmissionAssessment`: a cohort-grain characterization of spread; key attributes: outbreakRef, route, reproductionEstimate, severityProfile
• `immunizationCampaign`: a planned preventive effort; key attributes: antigen, targetCohort, area, period
• `coverageEstimate`: measured reach of immunization; key attributes: campaignRef, cohortBand, area, coverageRate, estimatedAt
• `publicHealthMeasure`: an intervention taken; key attributes: kind, scope, introducedAt, liftedAt, legalBasisRef

Relationships

• `notifiableCaseReport` -> contributesTo -> `populationHealthIndicator` (many-to-many): reports aggregate into several series
• `healthSignal` -> detectedFrom -> `populationHealthIndicator` (many-to-one): signals cite the series that raised them
• `outbreak` -> substantiatedBy -> `healthSignal` (one-to-many): a declaration rests on one or more signals
• `transmissionAssessment` -> characterizes -> `outbreak` (many-to-one): assessments are revised over an outbreak's course
• `publicHealthMeasure` -> respondsTo -> `outbreak` (many-to-one): measures cite the episode they address
• `coverageEstimate` -> measures -> `immunizationCampaign` (many-to-one): coverage is estimated repeatedly per campaign

Events

• `caseNotified`: a de-identified notifiable case report was received into surveillance
• `signalRaised`: surveillance detected an anomaly worth attention
• `outbreakDeclared`: an episode was formally declared on the basis of signals
• `measureIntroduced`: a public health measure came into force for a scope
• `measureLifted`: a measure was ended
• `campaignLaunched`: an immunization campaign began for a target cohort
• `coverageEstimated`: a coverage figure was computed and published for a cohort
• `outbreakClosed`: a declared episode was formally ended

Projections

• `publicDashboardView`: open aggregate indicators and active measures; omits any small-cell or re-identifiable slice
• `epidemiologistView`: fine-cohort series and outbreak detail under disclosure control; omits person-grain data, which never exists in this model
• `internationalReportView`: the notification subset required across borders; omits domestic operational detail
