Methodology

Source-tiering, verification process, geocoding rules, editorial corrections policy, and named accountability. This page is the foundation for every claim made anywhere on HantaOSINT.

Verification commitment

Every map marker, daily report event, country aggregate, and outbreak record on this platform is sourced to a primary public health authority, a peer-reviewed publication, or a named wire service report. Click any data point's source link to read the original. If a claim cannot be sourced to one of these tiers, it is not published.

Data sources by tier

The HantaOSINT source-tiering framework prioritises primary public health authorities and peer-reviewed publications. Lower tiers exist for early-signal monitoring but do not produce case markers without corroboration.

Tier 1 — Authoritative

Tier 2 — National health authorities

Tier 3 — Named wire services with official attribution

What we do not source from

Confidence levels

Every case carries a status reflecting the strength of underlying evidence:

StatusMeaningSourcing requirement
ConfirmedPCR-positive, official health authority statementTier 1 or Tier 2 with named lab
ProbableClinical case + epidemiological linkage + serology, awaiting PCRTier 1 with named lab
SuspectedClinical case + exposure history, no laboratory confirmation yetTier 1 or Tier 2
Under investigationProvisional positive result, classification disputed or pendingTier 1 or Tier 2 with explicit classification dispute documented
MonitoringContact tracing, quarantine, asymptomaticTier 1 or named official
ResolvedRecovered, ruled out, or outbreak closedTier 1 confirmation

Update cadence

During active multi-country clusters, the dashboard is updated daily by 18:00 UTC at the latest with verified events from the preceding 24 hours. Daily reports are published the morning following the report date. Major case-count changes, deaths, or new country additions are pushed to Telegram subscribers as soon as a Tier 1 or Tier 2 source confirms.

Outside active cluster periods, the dashboard reflects endemic surveillance baselines from PAHO, ECDC, and CDC, refreshed weekly during routine periods.

This is a human-edited platform. We do not falsely advertise automated real-time ingestion. The "last verified" timestamp in the top bar reflects the most recent editorial verification pass.

Geocoding

Cases are geocoded to the most specific public-knowledge location available, typically the city or province of confirmed exposure or the city where the patient is hospitalised. We do not geocode to street-level addresses for privacy reasons. Approximate locations within a region are placed at the regional centroid.

Editorial corrections policy

When we get something wrong, we mark it visibly. We do not silently edit.

  1. If a daily report or outbreak file contained a factual error, we revise the content and add a banner at the top of the affected page noting the correction and the date.
  2. The original error and its correction are logged on the public corrections page, including: the original claim, the corrected claim, the source that prompted the correction, and the date.
  3. Schema dateModified is updated on any revised page.
  4. If a correction would meaningfully alter how a reader understood the situation, we send a corresponding notification via the Telegram channel.

This policy aligns with Wikipedia, BBC, and major newsroom standards. The corrections log is permanent and indexed. If you spot an error, email editorial@hantaosint.com or contact@hantaosint.com.

What we do not do

Independence and funding

HantaOSINT is operated independently. The public dashboard, Telegram alerts for confirmed clusters, and editorial content are free indefinitely. Paid Pro and Enterprise tiers fund infrastructure and editorial work. We do not accept advertising or sponsorship from pharmaceutical manufacturers, medical device companies, or political organisations.

Editorial accountability

Editorial decisions on this platform are made by Hristo Stanchev, based in Plovdiv, Bulgaria. Background: 12 years in technical SEO and AEO consulting, including OSINT platform builds (iranwarlive.com, ww3chance.com). Not a trained epidemiologist. The methodology on this page is constructed from primary-source reading of WHO, CDC, ECDC, and peer-reviewed publications, and modelled on ProMED-mail editorial conventions.

This methodology is open for review. Working epidemiologists, public health professionals, and infectious disease researchers are invited to email editorial@hantaosint.com with corrections, additions, or critique. Reviewer contributions will be acknowledged in this section if requested.

Open data

The dashboard's structured data layer (case markers, country aggregates, outbreak records) is available via the public API under a CC-BY-SA license. Researchers and journalists are welcome to reuse the data; we ask only that you credit HantaOSINT and link back to the source page.
