How sources are classified
Hantaflow ranks sources by authority. Rank 1 = official surveillance from a national or supranational public-health body (CDC, WHO, ECDC, PAHO, UKHSA, RKI). Rank 2 = expert-curated alert systems (ProMED). Rank 3 = reputable news outlets via Google News and GDELT, used as early-signal complement to official data. The map and feed display ranks for every signal.
Status semantics
- Healthy: last fetch succeeded; freshness within expected cadence.
- Degraded: partial response, format change, or stale.
- Blocked: rate-limited, 4xx/5xx, or access policy change.
- Unknown: first fetch not yet performed.
Licensing posture
Hantaflow only republishes links and short metadata (title, source name, timestamp, country tag). Full article content is never republished from news sources. Numeric surveillance data from public-domain sources (CDC, UK OGL, Datenlizenz Deutschland, Etalab) is republished with required attribution. The Hantaflow JSON API is offered under CC BY 4.0; underlying source licenses are unchanged.
Subscribe (RSS + JSON)
Every feed below is also exposed as a structured output you can subscribe to or query programmatically. Use the JSON API for dashboards and ad-hoc analysis; use RSS for Feedly / Inoreader / e-mail digests.
- Global signal feed — /feed.xml (RSS) · /api/signals.json (JSON, full snapshot)
- Per-country —
/feed/countries/<slug>.xml(e.g. /feed/countries/argentina.xml, /feed/countries/germany.xml, /feed/countries/united-states.xml). One feed per country we monitor. - Per-language —
/feed/<lang>.xml(e.g. /feed/en.xml, /feed/de.xml, /feed/ru.xml, /feed/zh.xml). ISO 639-1 language code, one of the 17 we ingest.
