Hantavirus Outbreak Aboard the MV Hondius
A hantavirus outbreak linked to the Andes strain has struck the cruise ship MV Hondius, resulting in three passenger deaths and five confirmed infections. The vessel departed from Ushuaia, Argentina, on April 1 and is currently sailing toward Tenerife, with its arrival expected on Sunday, May 10. Health authorities across multiple countries are actively tracking individuals who may have been exposed to the virus.
The Andes strain causes hantavirus pulmonary syndrome, which carries a fatality rate of 38–40%. There is no vaccine or specific treatment available for this disease. Symptoms can emerge anywhere from one to eight weeks after exposure. The first case appeared on April 6 in a 70-year-old Dutch passenger, who died aboard the ship on April 11. His 69-year-old wife, who was hospitalized, passed away on April 26 at a hospital in Johannesburg. A molecular test conducted on May 4 confirmed hantavirus in her system. The third victim, a German national, died on the ship on May 2.
Current Situation on the MV Hondius
As of May 8, the MV Hondius carries 147 people, including 87 passengers and 60 crew members. The passengers represent 24 nationalities, with 17 Americans among them. In the United States, five states—Arizona, California, Georgia, Texas, and Virginia—are monitoring seven former passengers. New Jersey is additionally tracking two individuals. Seventeen Americans currently on board plan to return home via a charter flight and will be placed under quarantine in Nebraska.
The United Kingdom has confirmed two cases and one suspected infection. A 56-year-old British man, Martin Anstee, was evacuated on May 6 and is receiving treatment in the Netherlands. Some British passengers are currently on Tristan da Cunha island. Switzerland has also confirmed a case in a patient at the University Hospital Zurich, where the Andes strain was identified. The patient's wife, who was also on board, remains symptom-free and is in isolation.
Doctors emphasize that the risk to the general public is low.
Maria Van Kerkhove, a representative of the World Health Organization, stressed that 'this is not a virus that spreads like the flu or COVID. It is completely different.'Larry Gostin also noted, 'You won't catch it just by walking into a hotel lobby. The risk to people is very, very low.'
During a 2018–2019 outbreak in Argentina, each infected person transmitted the virus to an average of 2.12 individuals before quarantine measures were implemented, but that number dropped to 0.96 after isolation began. Five Ukrainian nationals aboard the MV Hondius show no signs of infection, further indicating a low risk of hantavirus spread among other passengers.
The hantavirus outbreak on the MV Hondius highlights the critical need for international monitoring and control of infectious diseases. While the risk to the broader public remains low, health services continue to actively track contacts and check the health status of individuals who may have been exposed. This incident also serves as a reminder of the importance of preparedness for potential infectious disease outbreaks on cruise ships and other confined spaces where people are in close contact.
As health authorities respond to the hantavirus outbreak on the MV Hondius, similar concerns arise regarding the risk of hantavirus exposure for military personnel in Ukraine. Living in trenches increases the likelihood of contracting this virus, which has severe health implications.
