This is the final installment of our five-part Summer Health Series. If you’ve been with us all summer, thank you. Catch up on Part 1: Ticks, Sunburn & Bug Bites, Part 2: Heat Illness, Part 3: Swimmer’s Ear, and Part 4: Summer Sports Injuries.
Summer Travel Is a Brooklyn Tradition. So Is Forgetting to Plan for It.
Summer in NYC means trips: a week back home with grandparents in Lahore or Lagos or Lima; a family beach week on the Jersey Shore; sleepaway camp upstate; a long-promised honeymoon in Thailand; a college kid trekking through South America. Every year, AG Urgent Care sees a wave of travel-related visits in May, June, and July — and another wave in August and September from people who came back with something they didn’t expect.
Most of those visits would have been shorter, easier, or unnecessary with a little planning. The single biggest mistake travelers make isn’t picking the wrong destination — it’s waiting until the week before the trip to think about health.
The single most important number in this post: the CDC recommends seeing a clinician at least 4 to 6 weeks before international travel — ideally 6 to 8 weeks. Some vaccines take two weeks to kick in, some need a second dose, and some prescriptions need to start days before you fly.
This guide covers what NYC families actually need to think about before, during, and after summer travel: vaccines, traveler’s diarrhea, mosquitoes and ticks, camp forms, what to pack in a travel kit, and what AG Urgent Care can handle same-day in Brooklyn and Queens — including for the inevitable last-minute trip.
Step One: Check Your Destination, Then Your Records
Different destinations carry different risks. A long weekend in Vermont needs nothing special; two weeks in rural India is a different conversation. The CDC keeps an excellent free tool at wwwnc.cdc.gov/travel — search your destination and it lists the recommended and required vaccines, current disease outbreaks, and travel notices. It is the single best starting point.
Once you know what your destination needs, check what you already have:
- Routine vaccines — make sure everyone in the family is up to date on MMR (measles, mumps, rubella), Tdap (tetanus, diphtheria, pertussis), polio, flu, and COVID. Measles in particular has surged in parts of Europe and Asia in recent years, and unvaccinated travelers are at real risk.
- Childhood vaccine series — kids traveling internationally sometimes need to start or accelerate their series earlier than the U.S. schedule (especially MMR for infants 6–11 months heading to high-risk areas).
- Records — find your immunization records before the appointment so you’re not paying for shots you’ve already had.
Travel-Specific Vaccines Worth Asking About
For trips outside North America and Europe, a few additional vaccines often come up. Whether you need them depends on the destination, the length of stay, the season, and what you’ll be doing.
| Vaccine | Often considered for | Notes |
|---|---|---|
| Hepatitis A | Much of Asia, Africa, Central & South America, parts of Eastern Europe | Spread through contaminated food/water. One dose protects for the trip; a second dose 6–12 months later extends protection long-term. |
| Typhoid | South Asia, Southeast Asia, sub-Saharan Africa, Latin America | Available as an injection or an oral capsule series. Especially important when visiting friends/relatives or eating outside hotels. |
| Yellow Fever | Parts of sub-Saharan Africa and tropical South America | Some countries require proof for entry. Only given at certified yellow fever vaccination centers. |
| Hepatitis B | Long stays, medical work, certain regions | Many adults under 50 had the series as kids; ask if you’re unsure. |
| Japanese encephalitis | Rural Asia, longer stays during rainy season | Two-dose series; rarely needed for short urban stays. |
| Rabies (pre-exposure) | Adventure travel, long stays where rabies post-exposure care is hard to access | Does not replace post-exposure shots if bitten — but buys time. |
| Cholera | Humanitarian or disaster-response travel; outbreak areas | Single oral dose; not routinely needed for tourist travel. |

This is meant as a conversation starter, not a checklist — every traveler’s risk profile is different, and a clinician will tailor recommendations to your specific itinerary.
Traveler’s Diarrhea: The Most Common Travel Illness, by Far
Even careful travelers get traveler’s diarrhea — it affects an estimated 30–70% of people traveling to higher-risk regions, depending on destination and season. It’s usually caused by bacteria (most often E. coli), occasionally by viruses or parasites, and almost always picked up through contaminated food or water.
Prevention: The Old Rule Still Holds
“Boil it, cook it, peel it, or forget it.” The riskiest items are the same everywhere:
- Tap water, including ice cubes, and brushing teeth with it
- Raw or undercooked seafood and meat
- Salads and raw vegetables washed in local water
- Unpeeled fruit, especially if you didn’t peel it yourself
- Unpasteurized dairy, soft cheeses, fresh juices from street stalls
- Food that’s been sitting at room temperature
Safe defaults: bottled or boiled water, food that’s served piping hot, fruit you peel yourself (bananas, oranges, mangos), and well-cooked staples. Hand hygiene matters too — soap and water when you can, hand sanitizer (≥60% alcohol) the rest of the time.
Treatment: Mostly Hydration. Sometimes Antibiotics.
Most cases resolve in a few days with rehydration alone. Oral rehydration salt packets are cheap, light, and worth packing for the whole family. For an adult with watery diarrhea and no warning signs, water plus electrolytes is the right call.
For moderate to severe cases — frequent stools that are disrupting travel, but no fever or blood — current guidelines support a short course of azithromycin (often a single 1,000 mg dose, prescribed in advance to carry “just in case”). Loperamide (Imodium) can be added to slow the diarrhea, or sometimes used alone for moderate symptoms.
Do NOT use loperamide (or other antidiarrheal medications) if:
- There’s blood in the stool
- There’s a high fever
- The patient is a child under 2
In those cases, get medical care. Bloody diarrhea, persistent high fever, signs of dehydration in a child, or symptoms lasting more than a few days all warrant evaluation — abroad, or as soon as you’re back.
Mosquitoes, Ticks, and Other Bites
Many of the most concerning travel illnesses — malaria, dengue, Zika, chikungunya, yellow fever, Japanese encephalitis — are spread by mosquito bites. Vaccines or prophylactic medications exist for some; prevention through bite avoidance is the foundation for all of them.
- Use EPA-registered repellents. Look for 20%+ DEET, picaridin, IR3535, or oil of lemon eucalyptus on exposed skin.
- Treat clothing with permethrin before the trip — it survives multiple washes and dramatically reduces bites and tick attachment.
- Cover up at dawn and dusk (peak mosquito hours for most species).
- Sleep under a permethrin-treated bed net in malaria zones if your room isn’t well screened or air-conditioned.
- Take malaria prophylaxis as prescribed. If your destination requires it, start before you go, take it during the trip, and continue after returning — exactly as directed.
For domestic trips — hiking in the Catskills, camp upstate, a Cape Cod week — the bigger bite-borne risks are Lyme disease and other tick-borne illnesses. Our Part 1 post on ticks covers prevention, tick removal, and when to come in.
For NYC Kids: Camp Physicals and Health Forms
Almost every sleepaway camp, summer program, sports league, and study-abroad program requires a recent physical and an immunization record. The forms always feel routine — until you realize the deadline is tomorrow.
AG Urgent Care can handle camp physicals, sports physicals, and most school forms as a same-day walk-in visit. We can:
- Complete the camp or sports form on the spot
- Update routine immunizations the child is due for
- Provide records you can email to the camp or program
- Flag any issues (a concerning heart murmur, new asthma symptoms) that need follow-up before camp starts
Bring the form, the camp’s vaccine requirements, and any past records you have. If your child has chronic conditions, allergies, or daily medications, also bring the medication list.
What to Pack in a Travel Health Kit
A small, water-resistant pouch in carry-on luggage is enough. The CDC’s recommended baseline, slightly adapted for real-world travel:
- Prescription medications — in original labeled bottles, with enough for the trip plus extra in case of delay
- Acetaminophen and ibuprofen — for pain, fever, headaches
- Loperamide (Imodium) — for travelers’ diarrhea, with caveats above
- Oral rehydration salt packets
- Antibiotic for travelers’ diarrhea — most commonly azithromycin, prescribed before you leave
- Antihistamines — for allergic reactions, bug bites, or sleep on long flights
- Hydrocortisone cream — for itchy bites and rashes
- Insect repellent with 20%+ DEET, picaridin, or oil of lemon eucalyptus
- Sunscreen (SPF 30+) and after-sun lotion
- Band-aids, gauze, medical tape, antibiotic ointment, blister care
- Thermometer (digital, compact)
- Hand sanitizer (at least 60% alcohol) and antibacterial wipes
- Masks — for crowded planes, trains, and medical visits abroad
- A copy of your vaccine records and a card with your insurance info, allergies, and emergency contacts
What AG Urgent Care Can Do — Before, During, and After Your Trip
Walk into any AG Urgent Care location in Brooklyn or Queens for:
- Travel consults — destination-specific guidance, recommended vaccines, and prescriptions for malaria prophylaxis, traveler’s diarrhea antibiotics, and altitude sickness
- Routine and travel vaccines we stock — including Hepatitis A, Hepatitis B, Tdap, MMR, flu, COVID, and typhoid (call your nearest location to confirm availability)
- Camp, sports, and school physicals — same-day walk-in, form completed on the spot
- Last-minute travelers — even one week out, we can often help with the highest-yield interventions: TD antibiotics, basic vaccines, and prescriptions you don’t want to be without abroad
- Telehealth visits — talk to an AG clinician from your couch (or your hotel room) without coming in. Helpful for pre-travel questions, prescription follow-ups, and getting eyes on a problem while you’re away. Learn more about AG telehealth →
- Post-travel illness — fever, persistent diarrhea, rash, or anything that doesn’t feel right after coming home
For yellow fever specifically, you’ll need a CDC-designated yellow fever vaccination center — we’ll point you to the nearest one. For complex, multi-country, or high-risk itineraries (months in remote regions, immunocompromised travelers, pregnant travelers), a dedicated travel medicine clinic is usually the right call; we can help you decide.
If You Get Sick While Traveling
Seek care abroad — don’t wait until you’re home — if:
- Fever over 102°F that doesn’t break with acetaminophen/ibuprofen
- Bloody diarrhea or diarrhea lasting more than 3 days
- Signs of dehydration: lightheadedness, very dark urine, dry mouth, sunken eyes in a child
- Severe abdominal pain or vomiting that won’t stop
- Animal bite or scratch — start the rabies post-exposure conversation immediately, even abroad
- Difficulty breathing, chest pain, fainting, severe headache, or any neurologic change
U.S. embassies and consulates can help you find reputable local providers. Your travel insurance (if you have it — and you should consider it for international trips) typically includes a 24/7 medical assistance line.
Reach Us From Anywhere: AG Telehealth
If something comes up while you’re away and you want to talk to a clinician you already know, AG Urgent Care’s telehealth service lets you connect with our team by video — without finding a clinic in an unfamiliar place. It’s especially useful for sorting out whether a symptom needs local care or can wait until you’re home, for follow-up on a prescription we sent you off with, or for triaging a minor issue with a kid. Telehealth has some state-by-state limits, so reach out to find out what we can do based on where you’re traveling. For anything serious or red-flagged above, get in-person care wherever you are.
When you get home, walk into AG Urgent Care if anything is lingering — especially fever, GI symptoms, rash, or unusual fatigue. Tell us where you went, what you ate or were exposed to, and what (if anything) was already treated. Some travel illnesses (malaria, dengue, typhoid) can present weeks after return; the travel history is a crucial clue.
Frequently Asked Questions
How far in advance should I see a clinician before international travel?
The CDC recommends at least 4 to 6 weeks before departure, and 6 to 8 weeks is even better. Some vaccines take two weeks to be effective, some require a second dose, and some prescriptions (like certain malaria pills) need to start days before you fly. If you’re a last-minute traveler, come in anyway — even a single visit a week out can meaningfully reduce your risk.
Do I need shots for a beach trip to the Caribbean?
For most all-inclusive resort trips to the Caribbean, the main recommendations are routine vaccines, plus Hepatitis A for some destinations and mosquito-bite prevention against dengue and Zika (especially important in pregnancy). Check the CDC’s destination page for your specific country.
Can I take antibiotics for traveler’s diarrhea preventively?
For most healthy travelers, the answer is no — routine antibiotic prophylaxis isn’t recommended because of side effects, resistance, and the fact that most cases of TD are mild. Carrying antibiotics to take only if symptoms develop is the standard approach. People with significant underlying conditions or short, mission-critical trips may be exceptions; talk to your clinician.
What about kids — is travel safe for infants?
Generally yes, with planning. Routine vaccines need to be up to date, some childhood vaccines can be given earlier than the U.S. schedule for travel, and a few things (malaria, certain destinations) deserve extra caution in infants and young children. Avoid yellow fever–risk areas with infants under 9 months whenever possible. A pre-travel visit is especially important when traveling with kids.
Should I get travel insurance?
For most international trips — yes, particularly a policy that includes medical evacuation coverage, which can run hundreds of thousands of dollars if needed. Your U.S. health insurance often won’t cover care abroad, and Medicare generally doesn’t outside the U.S.
I’m leaving in 5 days. Is it too late?
No. Last-minute travel visits are useful for getting any prescriptions you’ll want abroad (TD antibiotics, malaria prophylaxis if needed, an EpiPen refill), updating quick-acting vaccines, and reviewing the highest-yield prevention steps for your destination. Come in — even a short visit moves the needle.
Series Wrap-Up: Thanks for Reading This Summer
This was the last of our five-part Summer Health Series. Over the past few months we’ve covered the ground that lands most New Yorkers in urgent care between May and September — from ticks and bug bites to heat illness, swimmer’s ear, sports injuries, and now travel. If you missed any of them, the full series is linked at the top of this post.
We’ll be back in late summer with a Back-to-School Health series covering physicals, immunizations, sick-day decisions, and the new school year’s most common reasons for an urgent care visit.
