A rare and potentially deadly rodent-borne virus, hantavirus, has resulted in the deaths of several passengers aboard the Dutch cruise ship MV Hondius, according to the World Health Organization (WHO). The virus, which is transmitted by rodents, has prompted a global health response as authorities work to contain the outbreak and prevent further infections.
Details of the Outbreak
The outbreak was first identified on May 2, when WHO was notified of a cluster of infections aboard the ship, which had departed from Argentina in April. The vessel had been traveling across the Atlantic Ocean when the first case was reported.
As of May 7, WHO Director-General Dr. Tedros Adhanom Ghebreyesus confirmed that eight passengers had been infected, including three deaths. Five of the cases have been confirmed as hantavirus infections, while the remaining three are suspected.
The virus involved in the outbreak is identified as the Andes virus, a species that is known to cause severe illness and is capable of limited human-to-human transmission.
Timeline and Victims
The first victim, an adult male passenger, developed symptoms on April 6, just five days after the ship left Argentina. Initially presenting with fever, headache, and mild diarrhea, the man’s symptoms worsened, and by April 11, he was in respiratory distress and died on the same day. His symptoms were initially thought to be related to other respiratory diseases, so hantavirus was not suspected at the time.
The second death involved the man’s widow, who was also symptomatic. She was removed from the ship when it docked on Saint Helena on April 24. She later flew to Johannesburg, where her condition deteriorated, and she passed away on April 26. Tests confirmed she had been infected with hantavirus.
The third victim was a female passenger, who developed symptoms on the ship on April 28 and died four days later.
Current Health Status and Further Infections
The WHO has confirmed that one other passenger remains in intensive care in South Africa, while three other passengers who fell ill aboard the ship have received treatment from doctors in Cabo Verde and have since been evacuated to the Netherlands for further care. An eighth case involved a man who disembarked in Saint Helena and later reported symptoms in Switzerland.
No additional passengers or crew members on the ship are reported to be symptomatic at this time. However, given the six-week incubation period of the Andes virus, further cases may emerge. Despite this, WHO has assessed the overall risk to the public as “low” and believes that the outbreak will remain limited if public health measures are properly followed.
Global Health Response
In response to the outbreak, several health organizations are working together to prevent further spread. WHO’s Director of Epidemic and Pandemic Preparedness, Maria Van Kerkhove, emphasized that while the outbreak is serious, it does not pose the same level of global threat as COVID-19, stating, “Most people will never be exposed to this.”
The U.S. Centers for Disease Control and Prevention (CDC) is also closely monitoring the situation, particularly for American travelers on board the ship. The CDC has stated that the risk to the U.S. public remains extremely low, urging Americans aboard to follow health officials’ guidance as the situation is managed.
Ship’s Status and Future Plans
The MV Hondius is expected to arrive at Tenerife, a Spanish island, on May 10, where quarantine and screening measures will be implemented for the remaining passengers. The ship is currently following protocols under the guidance of medical teams and continues to cooperate with international health agencies to contain the outbreak.
Ongoing Investigations
Investigations into the source of the outbreak and the potential spread of the virus are ongoing. As the situation develops, authorities are taking steps to ensure the safety of passengers and prevent further infections.
