I was super careful the whole trip in Bali cooked food only, bottled water, no ice, sanitizer, the works. Thought I dodged it… then at 1 a.m. on departure day I started vomiting and, yeah, the other thing.
Did a 13-hour flight home like that. Needed an IV after landing and took almost a week to feel normal again.
Be extra careful and have a plan: carry meds, rehydration salts, and a change of clothes in your carry on. If it hits, focus on fluids and rest.
