• WHO declares an end to the hantavirus outbreak linked to the cruise ship MV Hondius.
• The outbreak resulted in 13 cases and three fatalities linked to the rare Andes virus.
• The final contact completed quarantine successfully, with no new cases reported since May 25.
• WHO continues research to enhance understanding and response to hantaviruses globally.
• Hantavirus predominantly spreads through rodent contact, presenting significant health risks.

The World Health Organization (WHO) has officially declared the hantavirus outbreak linked to the cruise ship MV Hondius over. This announcement comes after the completion of the quarantine for the last individual exposed to the virus, who tested negative, marking no further cases since May 25, as confirmed by WHO Director-General Dr. Tedros Adhanom Ghebreyesus during a press conference. The outbreak involved a total of 13 confirmed cases, including three deaths due to the rare Andes hantavirus, which is primarily found in regions of Argentina and Chile, according to Channel News Asia and South China Morning Post.

The cruise ship had embarked from Ushuaia, Argentina, on April 1, with subsequent stops in the South Atlantic before passengers were eventually evacuated in Tenerife. Importantly, WHO reported that over 650 contacts were traced across 33 nations, highlighting the extensive international monitoring efforts involved in managing the outbreak. Dr. Tedros emphasized that this is only the beginning in understanding the hantavirus and its implications, as the organization will lead a global study to further analyze the disease’s development, according to BBC and Al Jazeera.

Hantavirus is spread predominantly by contact with rodents or their excrete, which can lead to severe respiratory issues for infected individuals. Symptoms—including fever, muscle aches, and gastrointestinal discomfort—can present anywhere from one to eight weeks post-exposure, with severe cases potentially leading to lung complications. The Andes virus strain linked to this outbreak is especially notable for its ability to transmit between humans through close contact, thus posing ongoing public health challenges in the areas where it is present, according to BBC and Al Jazeera.
