@jakerosmarin A look inside my home for the next 35 days 🌊 This is the MV Hondius, the expedition ship I’m currently sailing on with @Oceanwide Expeditions as we make our way across the Atlantic I’m staying in a twin porthole cabin, and for my first time on board, I have to say… I’m genuinely so impressed. The ship is stunning and it really does feel like such a comfortable place to call home for the next few weeks I’ve previously sailed with Oceanwide on both the Plancius and Ortelius, so it’s really cool to now experience a third ship in their fleet and see how each one offers something a little different The Hondius was built specifically for expedition travel, carrying around 170 passengers, which allows it to access remote places that larger ships simply can’t reach ✨ Built in 2019 ✨ Designed to Polar Class 6 standards, meaning it’s made for navigating ice in both the Arctic and Antarctic ✨ Purpose built for exploration in some of the most remote regions on Earth What makes this experience so special is that the ship is designed to bring you closer to the destinations Oceanwide Expeditions specializes in polar travel and unique expedition itineraries, focusing on wildlife, remote landscapes, and immersive experiences That means things like: 🌊 Zodiac landings in remote locations 🐧 Wildlife focused itineraries 🧭 Expedition guides with deep knowledge of the regions we’re exploring And for this voyage… it means 35 days crossing the Atlantic to some of the most remote inhabited islands on Earth Still kind of surreal to say that out loud Also yes… this is officially my “semester at sea” 😂 . . . . . #oceanwideexp #semesteratsea #travelinspiration #shiptour #epicadventure ♬ Old Film – Kairo Vibe

An elderly passenger died on board early in the outbreak. His wife later became ill and died after being evacuated to a hospital in Johannesburg. A third person also died on the ship, while others required treatment, including intensive care.

What is hantavirus?

Hantavirus is rare but can be severe. It is usually spread through contact with infected rodents or contaminated dust. Symptoms can include fever, fatigue and serious breathing problems. There is no specific cure, but early medical care can improve outcomes.
