Health risks like stomach bugs and viruses can disrupt your vacation. To minimize these risks, practice good hygiene by wiping down surfaces on planes and in hotel rooms, using antibacterial wipes, and avoiding potentially unsafe foods like raw vegetables or cold meats. Carry a medical kit with essentials like rehydration tablets, antihistamines, and insect repellent. Staying informed about travel advisories and vaccinations is also crucial for a healthy trip.
