What you should know about this signal

  • Hantaviruses are usually transmitted to people through contact with infected rodents or their excreta.
  • The current cruise-ship cluster is linked to Andes virus, a hantavirus species for which limited person-to-person transmission has previously been reported after close and prolonged contact.
  • This is an active event, but current public-health assessments do not describe it as a COVID-like pandemic threat.
  • World Vitals distinguishes official counts from secondary reports and keeps source updates in an auditable timeline.

Processing notes

Counts are entered only when a source states the classification. Confirmed cases require laboratory confirmation. Probable and suspected cases are shown separately. Case fatality ratio is displayed as a crude early-cluster statistic and not as a stable disease-wide estimate.

Source updates will be archived with retrieval time, source URL, quoted numeric values, editor notes, and a machine-readable diff from the previous public dataset.
