This condition is quite common in Vietnam, especially when enjoying the country’s vibrant street cuisine. If you contract this condition, try to avoid medications that arrest diarrhea unless it is absolutely necessary while on the move. Maintain a diet of bland foods or fluids only, avoiding dairy products. Keep your fluid intake high in small, frequent sips to avoid dehydration. If the illness lasts for more than a few days or if your condition worsens, contact us for medical advice—and if a child suffers from diarrhea, it is recommended to delay travel plans and let the child rest.
