Live outbreak dashboard

This page provides context on how we track outbreaks. For real-time case counts, affected regions, and risk levels, visit the live dashboard.

How outbreaks are tracked

Hantavirus.app aggregates data from official public health sources in near real-time:

  • WHO Disease Outbreak News — global alerts and situation reports
  • CDC — US case surveillance and epidemiological updates
  • PAHO — regional updates for the Americas
  • ProMED — early warning reports from clinicians worldwide
  • AISStream — maritime vessel tracking for shipboard outbreaks

Understanding the data

  • Confirmed cases: Laboratory-verified by IgM serology, RT-PCR, or equivalent
  • Suspected cases: Clinically compatible illness with exposure history, awaiting lab confirmation
  • Active: Outbreak is ongoing with new cases in the last 30 days
  • Contained: No new cases for ≥2 incubation periods (≥16 weeks)
  • CFR: Case fatality ratio = deaths / confirmed cases × 100

Disclaimer

We aggregate official data; we do not generate primary epidemiological data. All case counts carry a source URL and verification timestamp. For official guidance, always consult your national health authority or the WHO.
