# HantaOSINT

> Independent OSINT-based global surveillance platform tracking hantavirus cases, outbreaks, and spillover events worldwide. Free public dashboard plus paid API tiers for institutional use. Data aggregated from WHO Disease Outbreak News, CDC Health Alert Network, ECDC, PAHO, ProMED-mail, and national health ministries.

## What this site is

HantaOSINT is a single-pathogen surveillance platform for hantaviruses. The public dashboard, Telegram alerts for confirmed clusters, and editorial content are free. Paid tiers (Pro and Enterprise) provide real-time API access, suspected case data, webhook alerts, and pre-publication signal feeds.

The site is operated independently. It is not a government source. Always defer to local health authorities for clinical guidance.

## Active outbreak (as of 11 May 2026)

- [MV Hondius cluster](https://hantaosint.com/outbreaks/2026-mv-hondius) — Multi-country Andes virus cluster traced to a polar expedition cruise that departed Ushuaia, Argentina on 1 April 2026. 9 confirmed cases, 3 deaths (33% case fatality rate), 14 countries tracking contacts. WHO IHR coordination active. R₀ for human chains <1.0 (Andes virus does not sustain transmission). Ship docked at Granadilla port, Tenerife, Spain on 10 May 2026 with passenger disembarkation underway.

## Editorial principles

- Source everything to primary public health authorities (WHO, CDC, ECDC, PAHO, ProMED, national ministries)
- Distinguish confirmed from suspected cases at all times
- Contextualize with base rates rather than headline numbers
- Correct openly when data shifts; archive previous versions
- Avoid panic framing; the job is information, not alarm
