As stomach bugs surge, medical experts are advising travelers to pack certain essentials to mitigate the impact of gastrointestinal illnesses, which commonly affect those on the go. Travelers' diarrhea, often caused by bacteria, is the most prevalent travel-related ailment, affecting a significant portion of individuals depending on their destination and the season.
The Centers for Disease Control and Prevention (CDC) recommends carrying oral rehydration salts or electrolyte packets to replenish fluids and electrolytes lost due to vomiting or diarrhea. Over-the-counter anti-diarrheal medication, such as loperamide, can be used for mild cases, but should be avoided if fever or bloody stools are present. Bismuth subsalicylate, like Pepto-Bismol, may also help prevent or alleviate travelers' diarrhea, though it is not suitable for everyone, including those with aspirin allergies or pregnant individuals.
Hand sanitizer with at least 60% alcohol is also advised for situations where soap and water are unavailable. Hydration is paramount if illness strikes, as dehydration can become a serious concern.
Preventing and Managing Illness
While most common stomach bugs resolve within one to three days without medical intervention, dehydration can necessitate professional care. Beyond packing specific medications, smart food choices can also reduce the risk of gastrointestinal illness. Thoroughly cooking produce, especially leafy greens and fresh herbs, to temperatures above 160 degrees Fahrenheit can eliminate parasites like Cyclospora, which is resistant to standard washing and chlorine.
To minimize risk, experts suggest opting for fruits and vegetables with thick skins that can be washed and peeled, such as bananas, avocados, and melons. However, it's important to note that even with careful food and beverage selections, the risk of gastrointestinal illness cannot be entirely eliminated due to factors like restaurant hygiene and local sanitation, which are often beyond a traveler's control.
Travelers should seek medical attention if diarrhea persists or worsens, especially if accompanied by fever, bloody stools, or signs of dehydration. Travelers' diarrhea can affect an estimated 30% to 70% of individuals during a two-week trip, underscoring the importance of preparedness.
