U.S. surveillance snapshot refresh
CDC's "Reported Cases of Hantavirus Disease" page—last updated with an banner—restates how surveillance began during the 1993 Four Corners outbreak, when HPS became nationally notifiable in 1995, and how expanded laboratory reporting captured non-pulmonary infections beginning in 2015. It continues to publish the cumulative total of 890 laboratory-confirmed infections nationwide from 1993 through year-end 2023 alongside demographic summaries.
Use this resource when you need official confirmation of surveillance scope—not media interpretations of annual totals.

Regional Americas epidemiological alert
PAHO issued an epidemiological alert regarding hantavirus pulmonary syndrome in the Region of the Americas on . WHO referenced this alert inside its May 2026 Disease Outbreak News as part of the broader regional situational awareness toolkit.
The alert is useful background on how hemisphere-wide institutions coordinate seasonal risk communication even when individual countries report only a small number of annual cases.

Clinical management references complement CDC guidance
NIH's StatPearls chapter on hantavirus pulmonary syndrome summarizes inpatient priorities such as careful fluid management, respiratory support, and monitoring for rapid deterioration—mirroring CDC's clinician brief, which explicitly notes intravenous ribavirin trials did not demonstrate effectiveness for treating HPS and should not be assumed to change outcomes.
Pair the StatPearls overview with CDC's clinician brief when discussing critical-care considerations with health professionals; patients should still defer treatment decisions to their care team.
