The World Health Organization (WHO) says the deadly hantavirus outbreak linked to the expedition cruise ship MV Hondius is expected to be formally declared over on July 2, provided no additional cases are detected.
WHO Director-General Dr. Tedros Adhanom Ghebreyesus said the outbreak has remained at 13 cases, including 12 confirmed infections and one probable case. Three people have died.
The outbreak was first reported in early May after several passengers who had traveled aboard the Dutch-flagged vessel became ill. Health officials later confirmed the infections were caused by the Andes virus, the only known hantavirus capable of limited person-to-person transmission through prolonged close contact.
More than 650 contacts across 33 countries and territories have been identified and monitored since the outbreak began. WHO said all but 54 contacts have completed the recommended monitoring period, with the remaining individuals expected to finish quarantine by July 2.
If no new infections are detected by then, WHO says the outbreak will be officially declared over.
Although the outbreak appears to be under control, health officials say investigations are continuing to determine how it began. Scientists are also studying virus samples to improve diagnostic tests, treatments and vaccines for future outbreaks.
The U.S. Centers for Disease Control and Prevention (CDC) has also ended its emergency response after all monitored passengers in the United States completed quarantine without any additional cases.
Health experts continue to emphasize that the risk to the general public remains low, noting that Andes virus spreads far less easily than common respiratory viruses and typically requires prolonged close contact with an infected person.
