Hantavirus Outbreak on Cruise Ship Hondius – What Happened

Overview

In early May 2026, the World Health Organization confirmed that three people died aboard the MV Hondius while it was sailing from Ushuaia, Argentina, toward Cape Verde. One of the deaths was laboratory‑confirmed as hantavirus infection, a disease spread mainly by contact with rodent urine, feces, or saliva.

Timeline of Events

May 1‑2 – Early Signs

• A 70‑year‑old passenger developed fever and muscle aches while the ship was near St. Helena.
• His condition worsened and he passed away on board; his body remained on the island.

May 3 – Confirmation and Escalation

• WHO announced one confirmed hantavirus case and five suspected cases.
• Three people had died, one was in intensive care in Johannesburg, and two crew members needed urgent medical help.
• The ship’s operator, Oceanwide Expeditions, said Cape Verdean authorities had not yet allowed disembarkation for medical evaluation.

May 4‑5 – Ongoing Response

• The Dutch government began coordinating the repatriation of the two symptomatic crew members and the deceased passenger to the Netherlands.
• South Africa’s Ministry of Health reported a severe respiratory illness outbreak linked to the cases.
• After clearance from Cape Verde, the ship is expected to continue its route to the Canary Islands.

What Is Hantavirus?

How It Spreads

Humans usually catch hantavirus when they inhale dust contaminated with rodent droppings or urine. It is not spread from person to person under normal circumstances.

Symptoms to Watch For

Early Phase (Days 1‑5)

• High fever (> 38.5 °C) and chills
• Severe muscle pain, especially in thighs, hips, and back
• Abdominal pain, nausea, or vomiting

Later Phase (After Day 5)

• Shortness of breath and a dry cough (fluid builds up in the lungs)
• Decreased kidney function
• Possible internal bleeding

If any of these symptoms appear, seek emergency medical care right away.

How to Protect Yourself While Traveling

• Avoid rodents: Keep cabins and gear clean; report any signs of mice or rats to ship staff.
• Seal your belongings: Use zip‑lock bags or hard cases for food and clothing.
• Store food safely: Keep snacks in rodent‑proof containers and never leave food out overnight.
• Sleep off the floor: Use a bunk or cot; avoid sleeping directly on the deck or ground.
• Ventilate and disinfect: Before using a room that’s been closed for a while, open windows, let fresh air in, and wipe surfaces with disinfectant.

What Authorities Are Doing

Local and International Cooperation

Oceanwide Expeditions is working with the WHO, the Dutch National Institute for Public Health and the Environment (RIVM), embassies, and the Dutch Ministry of Foreign Affairs. Medical teams in Johannesburg are treating the critically ill passenger, while plans are underway to move the deceased and two symptomatic crew members to the Netherlands once Cape Verde grants permission.

Traveler Advice

If you’re booked on a cruise or planning a trip to regions where rodents are common, stay informed about the ship’s health protocols, practice good hygiene, and let crew know immediately if you feel unwell.

Conclusion

The hantavirus incident on the MV Hondius reminds us that even on a vacation cruise, basic precautions against rodents matter. Recognizing early symptoms, keeping living spaces clean, and following crew guidance can greatly reduce risk. As health officials continue to investigate and coordinate care, staying updated through reliable sources like WHO and local health departments is the best way to protect yourself and others.
