The World Health Organization (WHO) declared the hantavirus outbreak over on Thursday after the final exposed individual completed their quarantine period and tested negative. No further cases have been reported since May 25, marking the end of the 60-day monitoring period.
The outbreak originated aboard the MV Hondius cruise ship, with 12 confirmed and one probable case, including three deaths. Health officials suspected human-to-human transmission, likely involving the Andes virus strain, the only hantavirus known to spread person-to-person. The exposure may have occurred during land excursions in Chile, Uruguay, and Argentina, though the exact source remains under investigation.
The Dutch-flagged ship had set off on April 1 from Ushuaia, Argentina, visiting remote islands before arriving in Tenerife, Spain, where remaining passengers were evacuated. The WHO emphasized that while the outbreak is over, scientific work to understand the episode continues.
Key Facts:
- Final quarantine ended on Thursday after 60 days.
