Key Takeaways

  • Schedule vaccinations 4-6 weeks before departure, as hepatitis A requires 2-4 weeks for immunity and yellow fever needs 10 days—some countries require proof of vaccination for entry.

  • Deep vein thrombosis risk increases 2-4 times on flights longer than 4 hours; walk every 2 hours and wear compression stockings rated 15-20 mmHg to maintain circulation.

  • Use insect repellents containing 20-30% DEET for 4-6 hours of protection against malaria and Zika-carrying mosquitoes, which are most active at dawn and dusk.

  • Traveler's diarrhea affects 20-40% of international travelers within the first week; stick to bottled water, avoid ice cubes, and choose thoroughly cooked foods from busy establishments with high turnover.

  • Pack a travel health kit with oral rehydration salts, antimotility medications like loperamide, broad-spectrum sunscreen (SPF 30+), and copies of prescriptions in both generic and brand names.

Summer is a popular time for travel, but it's important to prioritize your health and safety while on vacation. With a little preparation and some simple precautions, you can ensure a healthy and enjoyable trip for you and your family. Here are some expert tips to help you stay safe and healthy during your summer travels.

Plan Ahead and Be Proactive

Before you leave for your trip, think about your health needs in advance. If you have any chronic health conditions, schedule a checkup with your doctor to ensure you're in good health for travel. Research your destination to learn about any specific health risks and necessary precautions.

Pack a Travel Health Kit

Be prepared for the unexpected by packing a travel health kit with essential items such as:

  • Anti-inflammatory drugs (ibuprofen or naproxen)

  • Anti-diarrhea medication (Imodium)

  • Motion sickness medication

  • Band-Aids and antiseptic cream

  • Drugs for stomach upset

  • Spare pair of glasses (if you wear them)

  • Mosquito or bug repellents (if necessary)

If you take prescription medications, pack enough for the entire trip in your carry-on luggage in case your checked baggage is lost.

Get Vaccinated and Consider a Flu Shot

Ensure you have all the necessary vaccinations and medications before you leave, especially if you're traveling to developing countries where the risk of tropical and infectious diseases is high. Flu shots are also recommended for people traveling to developing nations, in groups, or on cruises, as they can help prevent influenza and avoid unnecessary scares related to SARS-like symptoms.

Practice Good Hygiene

Good hygiene is your first line of defense against viral and bacterial illnesses. Wash your hands frequently and thoroughly, especially before preparing or eating food, treating wounds, or tending to someone who is sick. Use hot water, scrub for at least 15 seconds, and dry your hands with a clean paper towel or air dryer.

Eat and Drink Sensibly

To minimize the risk of travelers' diarrhea, follow these guidelines:

  • Drink only bottled or boiled water

  • Eat well-cooked meat and seafood

  • Avoid food and drinks from street vendors or unhygienic establishments

  • Peel raw fruits and vegetables yourself

  • Avoid putting ice in your drinks

If you do experience diarrhea, consider taking antibiotics prescribed by your doctor to shorten the illness duration.

Prevent Blood Clots During Long Trips

Sitting in a cramped position for extended periods can increase your risk of blood clots. To minimize this risk, drink plenty of non-alcoholic fluids, move your legs frequently, and take deep breaths to improve circulation. Compression stockings and heparin injections may be necessary for those at higher risk.

Protect Yourself from Insect Bites

Mosquitoes and ticks can carry various diseases. To minimize your risk of being bitten:

  • Stay indoors at dawn, dusk, and evening when mosquitoes are most active

  • Wear long-sleeved shirts, long pants, and hats

  • Tuck your shirt into your pants and your pants into your socks

  • Wear boots instead of sandals

  • Inspect yourself and your clothing for ticks during and after outdoor activities

  • Use insect repellents containing DEET on skin and permethrin on clothing and gear

By following these expert tips and prioritizing your health and safety, you can enjoy a worry-free summer vacation. Remember, a little preparation goes a long way in ensuring a healthy and memorable trip.
