How do I avoid getting sick on a cruise?

Question

Accepted Answer

Cruise illness is mostly stomach bugs and respiratory viruses moving through a dense, shared space, so your defense is boring hygiene done relentlessly. The CDC's Vessel Sanitation Program leads with handwashing: wash your hands often, especially after using the toilet and before eating, because handrails, elevator buttons, shared utensils, and other people spread illness. Use the sanitizer stations at dining entrances every time. On the food side, the CDC's travel food guidance says avoid lukewarm food: buffet hot food should be steaming and cold food properly chilled, so take fresh batches rather than the tray that has sat. Other high-yield moves: be current on flu and COVID vaccines before you sail, use your own cabin bathroom instead of the public ones near the buffet when you can, do not touch your face between handrail and handwashing, and stay in your cabin and report it if you do get vomiting or diarrhea, both to recover and because ships isolate sick passengers to stop outbreaks. Most cruise illness is a few miserable days, not a ruined trip, and the kit that helps is simple: rehydration salts, your usual painkillers, and any prescription medicine in your hand luggage.
