Data sources, confidence levels, update cadence, geocoding rules and corrections policy. Built for the same standard of transparency you would expect from a public health agency or wire service.
HantaOSINT is built on the same principles that have made other independent OSINT trackers — like ncov2019.live during COVID-19 or Bellingcat's conflict mapping — useful and trustworthy: transparent sourcing, clear confidence levels, and rapid corrections when the data shifts.
We aggregate from primary public health authorities and recognized open-source channels. Every case marker on the map links back to its primary source.
We monitor wire services (Reuters, AP, AFP), national broadcasters, and reputable health journalism outlets for early signal. Tier 3 sources do not become case markers until corroborated by Tier 1 or Tier 2.
Every case marker carries a status reflecting our confidence in the data:
| Status | Meaning | Sourcing requirement |
|---|---|---|
| Confirmed | PCR-positive, official health authority statement | Tier 1 or Tier 2 with named lab |
| Suspected | Clinical case, exposure history, awaiting lab | Tier 1 or Tier 2 |
| Monitoring | Contact tracing, quarantine, asymptomatic | Tier 1 or named official |
| Resolved | Recovered, ruled out, or outbreak closed | Tier 1 confirmation |
The dashboard refreshes data every four hours during active outbreaks and every twelve hours during baseline endemic surveillance. Major case-count changes, deaths, or new country additions are pushed immediately to subscribers via email and Telegram.
Cases are geocoded to the most specific public-knowledge location available — typically the city or province of confirmed exposure. We do not geocode cases to street-level addresses for privacy reasons. Approximate locations within a region are placed at the regional centroid.
When data shifts — a suspected case is ruled out, a death count is revised, a strain identification changes — we update immediately and log the change in the Briefings feed. We do not silently revise. If you spot an error, email contact@hantaosint.com.
We do not aggregate social media posts, anonymous tips, or unsourced rumor. We do not publish identifying information about individual cases. We do not speculate about outbreak origins beyond what authoritative sources have stated. We are not a government source — always defer to your local public health authority for clinical guidance.
HantaOSINT is operated independently. The platform is currently self-funded; we do not accept advertising or sponsorship from pharmaceutical manufacturers, medical device companies, or political organizations. If subscriber tiers are introduced in future, the public dashboard remains free.
Aggregated case data — countries, strains, outbreak summaries — is available via the public API under a CC-BY-SA license. Researchers and journalists are welcome to use the data; we ask only that you credit HantaOSINT and link back.
