7/2/2026, 11:57:19 PM
Outbreak Summary
The World Health Organization (WHO) announced on 2 July 2026 that the hantavirus outbreak linked to the cruise ship MV Hondius is over. It infected 13 individuals—12 confirmed and one probable—and caused three deaths. No cases have been reported since 25 May.
Background & Context
Outbreak involved Andes strain of hantavirus, a pathogen endemic to Argentina and Chile, only hantavirus known to spread between humans. MV Hondius departed on 1 April, visited South Atlantic islands, and docked in Tenerife, Spain, for evacuation.
Timeline of Key Events
WHO received an alert about severe respiratory illness on MV Hondius on 2 May. Passengers disembarked in Tenerife on 10 May and entered quarantine. Final monitored contact tested negative on 25 May, and WHO declared the outbreak over 2 July.
Data & Statistics
Thirteen cases—12 confirmed, one probable—caused three deaths. Least 11 confirmed Andes virus infections were reported. Over 650 contacts in 33 countries were traced and monitored, with a 42-day quarantine for exposure.
Official Statements & Responses
WHO Director-General Dr. Tedros Adhanom Ghebreyesus said exposed individual completed quarantine, tested negative, and returned home. He noted response involved contact tracing, testing, and monitoring by authorities. WHO will work with partners to advance understanding of hantavirus and support development of diagnostics, therapeutics, and vaccines.
Criticism & Opposition
Experts noted no vaccine or treatment exists for hantavirus, exposing gaps in preparedness for zoonoses. Reliance on quarantine and contact tracing is limited, prompting calls for accelerated research and surveillance.
On-the-Ground Reports
Four Canadian passengers after returning on 10 May; one tested positive but recovered. Passengers were transferred boat to Granadilla de Abona, Tenerife, repatriated, while ship docked in Rotterdam, Netherlands, on 18 May.
Conflicting Reports & Gaps
Sources report either 11 or 12 confirmed Andes virus infections, creating a discrepancy. The source of the infection—land before boarding or aboard the vessel—remains unclear.
