Source tier system
Official
Authoritative public health bodies. Lowest signal volume, highest credibility.
Academic
University centres or expert-curated outlets. Medium volume, expert-reviewed.
News
General media reporting. Highest volume, requires triage.
How we process signals
- Each source's RSS or API is fetched on a schedule. Items are filtered for hantavirus mentions in title or body.
- Multilingual classifier identifies the kind: local case reported, imported case, policy/monitoring only, or quiet signal. Country detector matches the strongest geographic mention.
- Cross-source deduplication via normalised title hash. Each surviving signal is published with its tier, kind, country attribution and link back to the primary source.
What we explicitly do not do
- We do not generate primary epidemiological data — every figure here is sourced.
- We do not claim signals are confirmed cases. Numbers reflect signal volume, not patient counts.
- We do not provide medical advice or replace official health guidance.
Known limits
Hantavirus is a sparse disease (~150–300 globally reported HPS + ~150,000 hospitalised HFRS per year, dominated by China). Real-time confirmed case feeds do not exist; we surface signals and label confidence with the tier system. Several feeds (CIDRAP, original ProMED RSS) returned 404 during integration and are awaiting replacement endpoints.
