From a Korean War mystery fever to a Patagonian super-spreader event, here's how hantavirus shaped — and was shaped by — global public health.
1951–1954
Korean Peninsula · 3,000+ UN soldiers
During the Korean War, more than three thousand UN troops fell ill with an unknown hemorrhagic fever near the Hantan River. The agent — later named Hantaan virus — wasn't isolated until 1976 by Dr. Ho Wang Lee.
1976
South Korea · —
Dr. Ho Wang Lee isolated the virus from striped field mice (Apodemus agrarius) and named it after the Hantan River. The discovery launched the entire field of hantavirus research.
1993
New Mexico, Arizona, Utah, Colorado (USA) · 24 cases · 12 deaths
An unexplained cluster of healthy young Navajo adults dying of acute respiratory failure. Within weeks, CDC identified a new hantavirus — Sin Nombre — carried by deer mice. This was the discovery of Hantavirus Pulmonary Syndrome (HPS).
1995
Argentina (El Bolsón) · 20+ cases
An outbreak in Patagonia revealed Andes virus — the only hantavirus with confirmed person-to-person transmission. A medical doctor became infected after treating patients, alerting researchers to the unique risk.
1998–1999
Southeastern USA · Sporadic
New hantavirus species identified in cotton rats and rice rats. Demonstrated that HPS wasn't limited to the Southwest — surveillance expanded nationwide.
2012
Yosemite National Park, California (USA) · 10 cases · 3 deaths
Visitors who stayed in 'Signature Tent Cabins' contracted HPS from deer mice nesting in the double-walled insulation. The park notified ~10,000 international visitors. Cabins were dismantled and the design banned.
2018–2019
Chubut Province, Argentina · 34 cases · 11 deaths
A super-spreader event in a small Patagonian town confirmed sustained person-to-person transmission of Andes virus. Authorities imposed quarantine — the first ever for hantavirus.
2024
Santa Fe, New Mexico (USA) · 1 death
The high-profile death of actor Gene Hackman's wife, Betsy Arakawa, from HPS brought renewed public attention to deer mouse exposure risk in rural Southwest homes.
2026
Atlantic / South Africa / Saint Helena · 7 cases · 3 deaths
WHO DON 599 documented a hantavirus cluster among cruise passengers and crew, including Saint Helena's first-ever recorded case. Investigation is ongoing.
