The last person to have come into contact with someone confirmed to have the Andes variant of hantavirus completed their six-week quarantine on Thursday, tested negative and returned home, triggering the World Health Organization to declare the cruise ship-linked outbreak officially over.

The outbreak, which infected 13 people and killed three, involved the Andes virus, a rare hantavirus strain.

There were 12 confirmed and one probable case stemming from the MV Hondius, including three deaths.
