The World Health Organization (WHO) has detailed its rapid response to a hantavirus outbreak originating from a Dutch-flagged cruise ship, the MV Hondius, which has resulted in three deaths and multiple confirmed cases.
The incident, which began with a cluster of severe respiratory illnesses reported by the United Kingdom, highlights the critical role of international health regulations in managing global health crises.
The Outbreak Unfolds
The alarm was raised last Saturday when the UK notified WHO of a cluster of passengers on the MV Hondius exhibiting severe respiratory illness.
The ship had traveled from Argentina
to Cabo Verde. So far, eight cases have been reported, with five confirmed as hantavirus and three suspected. Three of these cases have been fatal.
Dr. Tedros Adhanom Ghebreyesus, the Director-General, in opening remarks at a media briefing, outlined the sequence of events and WHO’s actions.
The hantavirus involved is the Andes virus, known for its ability to transmit between humans through close and prolonged contact, a rare characteristic among hantaviruses, which are typically carried by rodents.
The first recorded case was a man who developed symptoms on April 6th and died on the ship on April 11th. Hantavirus not initially suspected due to symptoms resembling other respiratory diseases.
His wife, who disembarked in Saint Helena while symptomatic, later died in Johannesburg on April 26th, where tests confirmed hantavirus. The third fatality was a woman who succumbed to the illness on May 2nd after developing symptoms on April 28th.
Another passenger remains in intensive care in S’Africa after being evacuated from Ascension Island. The three other symptomatic passengers evacuated to the Netherlands, with two now stable and one asymptomatic in Germany.
International Cooperation and Risk Assessment
WHO has assessed the public health risk as low, despite the seriousness of the incident. This assessment is based on the contained nature of the outbreak and the swift international response.
The organization is working closely with multiple govts and partners, including Cabo Verde, the Netherlands, South Africa, Spain, and the United Kingdom, to manage the situation under the International Health Regulations.
The ship is currently en route, with WHO confident in Spain’s capacity to manage the risk, which is also assessed as low for the Canary Islands population.
Onboard Measures and Ongoing Investigations
To prevent further spread, all remaining passengers on the MV Hondius have been asked to stay in their cabins, which undergoing disinfection. Symptomatic individuals are immediately isolated.
They are conducting medical assessments and gathering information to evaluate infection risks. WHO is also developing operational guidance for the safe and respectful disembarkation and onward travel of passengers and crew.
Twelve countries whose nationals disembarked in Saint Helena have been informed, and health authorities in South Africa are being supported to follow up with individuals on a flight that carried one of the deceased.
WHO is collaborating with Argentine health authorities, leveraging their expertise with the Andes virus, and has arranged for 2500 diagnostic kits to be shipped from Argentina to laboratories in five countries.
A Testament to Global Health Preparedness
WHO DG expressed gratitude to all partners, including the NICD in South Africa, the Institut Pasteur Dakar in
Senegal, and the HUG in Switzerland, as well as the ship’s operator, passengers, and crew.
commending the captain’s efforts to protect those under his care.
This incident underscores the importance of the International Health Regulations and the effectiveness of a coordinated global response in mitigating potential pandemics.
WHO remains committed to providing care, ensuring safety and dignity for those affected, and preventing further viral spread.
