Cruise ships and risky destinations pose health hazards for travelers

Cruise liners create ideal conditions for rapid spread of infections, as passengers share confined spaces, elevators, restaurants and ventilation systems. Past outbreaks such as the 2020 Diamond Princess incident illustrate how quickly viruses can circulate among thousands of people on board, especially in poorly ventilated areas and communal water facilities.

A separate travel‑risk assessment identifies the world’s most dangerous and safest countries for 2026. Nations including Afghanistan, Ecuador, Haiti, Myanmar, Pakistan, Somalia, Sudan, Ukraine and Venezuela rank highest for armed conflict, crime and limited medical care, while Australia, Denmark, Finland, Greenland, Ireland, Canada, Croatia, Norway, Portugal, Slovakia, Slovenia and the Czech Republic are highlighted as the safest for tourists. Both reports underline the importance of checking health and safety conditions before traveling, ensuring vaccinations are up to date, and following hygiene practices to reduce infection risk.
