Share this article

Summer travel season is here — and whether you’re heading to the beach, boarding a plane, camping outdoors, or attending large events, preparation can go a long way toward keeping you healthy while away from home.

In the latest episode of Transmission Interrupted, host Jill Morgan (Emory University Hospital) shares practical, prevention-focused advice on infectious disease risks, food and water safety, vector-borne illnesses, and general summer preparedness. Here are some of the top takeaways from the episode.

1. “What’s common is common.”

One of the most important reminders from the episode is that the illnesses most likely to affect travelers are often the same ones people encounter at home — respiratory viruses, gastrointestinal illnesses, dehydration, and foodborne infections.

Basic prevention measures still matter:

• Wash your hands frequently
• Avoid touching your face
• Cover coughs and sneezes
• Stay home or mask if you’re sick
• Carry hand sanitizer for situations where soap and water aren’t available

2. Travel vaccines matter.

Before traveling, especially internationally, make sure you’re up to date on recommended vaccines. Depending on your destination, that may include routine vaccines as well as region-specific immunizations.

The episode also highlights the importance of remembering that diseases such as influenza, COVID-19, and measles continue to circulate globally — even during the summer months.

3. Respiratory etiquette is still important.

Travel often means crowded airports, airplanes, buses, cruise ships, and tourist destinations. Morgan emphasizes that masking while symptomatic and practicing good respiratory hygiene can help protect fellow travelers.

The episode encourages listeners to:

• Carry masks while traveling
• Use tissues or cough into your elbow
• Practice hand hygiene after coughing or sneezing
• Be considerate of others if you develop symptoms during travel

4. Mosquito-borne illnesses are a major summer concern.

Travelers heading to tropical or subtropical destinations may encounter mosquito-borne diseases that are uncommon in many parts of the United States.

The episode discusses several illnesses travelers should be aware of, including:

• Dengue
• Chikungunya
• Yellow fever
• Oropouche virus

Preventive strategies include:

• Wearing insect repellent
• Using long sleeves and pants when possible
• Staying aware of local outbreaks and travel advisories
• Avoiding mosquito-heavy areas when feasible

5. Food and water safety can make or break a vacation.

Gastrointestinal illnesses remain one of the most common travel-related health problems.

The episode highlights the importance of:

• Cooking foods thoroughly
• Keeping cold foods cold
• Avoiding undercooked seafood and meats
• Washing hands before eating
• Knowing whether water sources are safe, especially while camping or traveling internationally

Morgan also discusses risks associated with pathogens such as:

• Salmonella
• Vibrio
• Norovirus

6. Norovirus isn’t just a cruise ship problem.

Although norovirus often makes headlines because of cruise ship outbreaks, the episode explains that it spreads in many settings and is highly contagious.

Key prevention tips include:

• Frequent handwashing with soap and water
• Careful cleaning of contaminated surfaces
• Avoiding food preparation when ill
• Staying mindful of shared spaces during travel

7. Summer heat can be dangerous.

Infectious diseases aren’t the only travel health concern. The episode also addresses heat exhaustion and heat stroke, which become increasingly common during summer travel and outdoor events.

Important reminders include:

• Stay hydrated
• Monitor children and older adults closely
• Recognize signs of heat illness early
• Take breaks from direct sun exposure
• Carry water wherever you go

As Morgan notes throughout the episode: hydrate, hydrate, hydrate.

8. Water safety deserves attention too.

The episode emphasizes that drowning risks are often underestimated and may not look the way people expect.

Travelers are encouraged to:

• Closely supervise children around water
• Remain attentive at pools, lakes, and beaches
• Avoid distractions while supervising swimmers
• Stay aware of changing conditions in open water

9. Pack a simple travel health kit.

Preparation can make a big difference when minor illnesses or injuries happen away from home.

Morgan recommends travelers consider packing:

• Hand sanitizer
• Masks
• Sunscreen
• Insect repellent
• Bandages and basic first aid supplies
• Fever reducers/pain relievers
• Allergy medication
• Reusable water bottles

10. Responsible travel helps protect everyone.

A recurring theme throughout the episode is community responsibility. Travel safety isn’t just about protecting yourself — it’s also about protecting the people around you.

Simple actions like masking when sick, washing your hands, staying home when possible, and practicing good hygiene can help reduce the spread of illness during busy summer travel months.
