Travel Medicine: Stay Healthy Before, During & After Your Trip

You’ve booked the flights, mapped out the itin­er­ary, and start­ed a pack­ing list. But tucked between ​‘sun­screen’ and ​‘trav­el adapter’ is one item many trav­el­ers skip: a vis­it to a trav­el med­i­cine provider. It’s easy to over­look when you’re excit­ed, but pro­tect­ing your health before you leave is just as impor­tant as plan­ning where you’ll eat.

Whether you’re head­ing to South­east Asia for two weeks or spend­ing a month on a human­i­tar­i­an trip in sub-Saha­ran Africa, the right prepa­ra­tion can mean the dif­fer­ence between a trip you’ll always remem­ber and one you’d rather forget.

What is Trav­el Medicine?

Trav­el med­i­cine is spe­cial­ized health­care focused on pre­vent­ing ill­ness dur­ing inter­na­tion­al trav­el. It’s not just about get­ting shots before you go — a trav­el health appoint­ment is a per­son­al­ized risk assess­ment based on where you’re head­ed, what you’ll be doing, and your indi­vid­ual health his­to­ry. A typ­i­cal vis­it includes: 

• Review­ing your des­ti­na­tion and planned activities
• Updat­ing rou­tine vaccines
• Rec­om­mend­ing des­ti­na­tion-spe­cif­ic vac­cines (the CDC’s trav­el health notices are a great start­ing point to under­stand risk lev­els by region)
• Pre­scrib­ing pre­ven­tive med­ica­tions when needed
• Pro­vid­ing safe­ty guid­ance on food, water, insects, and more 

If you’ve won­dered, ​“Do I real­ly need a trav­el clin­ic appoint­ment?” the hon­est answer is: it depends on where you’re going. But for many inter­na­tion­al des­ti­na­tions, the answer is yes. 

“I want patients to know that they should sched­ule an appoint­ment to see their PCP before embark­ing on an over­seas trip, espe­cial­ly to high-risk areas. Their PCP can guide and advise the patient on required and rec­om­mend­ed vac­cines, if malar­ia pro­phy­lax­is is required, and if the patient would ben­e­fit from hav­ing antibi­otics or anti-nau­sea med­ica­tions on hand. Patients should know that they can make an appoint­ment to see their PCP for this. They do not need to see a spe­cial­ist unless rec­om­mend­ed by their PCP. This can help ensure a smoother and health­i­er inter­na­tion­al trip.” — Dr. Matthew Strauch, Inter­nal Med­i­cine Provider with Duly Health and Care 

Plan­ning a trip abroad? Sched­ule your trav­el med­i­cine appoint­ment with a Duly pri­ma­ry care provider (PCP) at least 4 – 8 weeks before depar­ture so you have time for vac­cines and pre­ven­tive med­ica­tions to take effect. 

Who Should See a Trav­el Med­i­cine Provider?

Not every trip car­ries the same lev­el of risk. A week­end in Lon­don looks very dif­fer­ent from a trekking expe­di­tion in rur­al Nepal. You should strong­ly con­sid­er a trav­el med­i­cine vis­it if you’re:

• Trav­el­ing out­side the U.S., Cana­da, West­ern Europe, Japan, or Australia
• Vis­it­ing rur­al areas or small towns rather than major cities
• Stay­ing for an extend­ed period
• Trav­el­ing for human­i­tar­i­an, mis­sion, or health­care work
• Plan­ning adven­ture trav­el — hik­ing, wildlife expo­sure, or water activities
• Going on a cruise or group tour through mul­ti­ple countries

Some trav­el­ers face a high­er risk of com­pli­ca­tions from trav­el-relat­ed ill­ness and need extra planning: 

• Chil­dren and infants
• Adults over 60
• Preg­nant travelers
• Peo­ple liv­ing with dia­betes, heart dis­ease, lung dis­ease, or oth­er chron­ic conditions
• Any­one who is immuno­com­pro­mised: the CDC’s Immuno­com­pro­mised Trav­el­er resource offers help­ful guid­ance for this group.

Even if you’re trav­el­ing to a low-risk des­ti­na­tion, a con­sul­ta­tion ensures you have accu­rate, up-to-date guid­ance. Health risks can shift by sea­son, by region, and even by what’s cur­rent­ly circulating. 

When Should I Sched­ule a Trav­el Health Visit?

The sweet spot is 4 to 8 weeks before your depar­ture. That win­dow gives your body time to build immu­ni­ty and allows for vac­cines that require mul­ti­ple dos­es or med­ica­tions that need to be start­ed in advance.

Trav­el­ing soon­er than that? Still go. Some vac­cines and med­ica­tions can pro­vide mean­ing­ful pro­tec­tion even on a short­er time­line, and the safe­ty guid­ance alone is worth the vis­it. Last-minute trav­el­ers ben­e­fit from per­son­al­ized advice just as much as those with months to spare.

What to Expect at Your Trav­el Med­i­cine Appointment

Your provider will tai­lor the vis­it entire­ly to your itin­er­ary and health his­to­ry. Appoint­ments usu­al­ly run 20 to 40 min­utes, depend­ing on where you’re going and how com­plex your trip is. Here’s what the con­ver­sa­tion will cover:

• Your des­ti­na­tion in detail. This includes spe­cif­ic coun­tries and regions, urban vs. rur­al set­tings, length of stay, trav­el sea­son, and what you’ll be doing. Health risks can vary sig­nif­i­cant­ly even with­in the same country.
• Your med­ical his­to­ry. You’ll dis­cuss your vac­ci­na­tion sta­tus, any past reac­tions to vac­cines, cur­rent med­ica­tions, and chron­ic health con­di­tions. If you have vac­ci­na­tion records, bring them — but don’t stress if you can’t find them.
• Your per­son­al­ized plan. Based on all of that, your provider may rec­om­mend vac­cine updates, pre­ven­tive med­ica­tions, and spe­cif­ic safe­ty pre­cau­tions for your trip.

Trav­el Vac­cines: What You May Need

Trav­el vac­cines fall into two cat­e­gories: rou­tine and destination-specific.

Rou­tine vac­cines are ones you should already be up to date on before any inter­na­tion­al trav­el. These include Tdap (tetanus, diph­the­ria, and per­tus­sis), MMR (measles, mumps, and rubel­la), influen­za, COVID-19 if rec­om­mend­ed, and vari­cel­la (chick­en­pox). Out­breaks of vac­cine-pre­ventable dis­eases can occur in areas with low­er vac­ci­na­tion rates, so stay­ing cur­rent matters.

Des­ti­na­tion-spe­cif­ic vac­cines pro­tect against ill­ness­es that are rare in the U.S. but com­mon in oth­er parts of the world. Depend­ing on your itin­er­ary, you may need pro­tec­tion against hepati­tis A, hepati­tis B, typhoid, yel­low fever, Japan­ese encephali­tis, or rabies. Some coun­tries require proof of cer­tain vac­ci­na­tions, such as yel­low fever, for entry.

Sup­pose you’re won­der­ing whether trav­el vac­cines are safe: most cause only mild, tem­po­rary side effects, such as sore­ness or fatigue. Seri­ous reac­tions are rare. The World Health Orga­ni­za­tion’s Inter­na­tion­al Trav­el and Health guide pro­vides a thor­ough overview of vac­cine rec­om­men­da­tions by destination.

Med­ica­tions for Trav­el Protection

Vac­cines aren’t the only tool in your kit. Depend­ing on where you’re going, your provider may pre­scribe pre­ven­tive or just-in-case medications.

Malar­ia pre­ven­tion is one of the most com­mon trav­el med­ica­tion con­ver­sa­tions. If your des­ti­na­tion car­ries malar­ia risk, you’ll like­ly need pre­scrip­tion pills — start­ed before trav­el and con­tin­ued after you return. Accord­ing to the CDC, malar­ia remains a seri­ous risk in parts of sub-Saha­ran Africa, South­east Asia, and South Amer­i­ca, so don’t skip this con­ver­sa­tion if your itin­er­ary includes those regions.

Trav­el­er’s diar­rhea is one of the most com­mon ill­ness­es abroad, affect­ing an esti­mat­ed 30 to 70 per­cent of inter­na­tion­al trav­el­ers depend­ing on the des­ti­na­tion. Your provider can give you guid­ance on safe food and water prac­tices and can pre­scribe anti-nau­sea med­ica­tion, anti-diar­rheal med­ica­tion, or, in some cas­es, antibi­otics to have on hand.

Oth­er med­ica­tions worth dis­cussing include alti­tude sick­ness pre­ven­tion (espe­cial­ly for high-ele­va­tion des­ti­na­tions), motion sick­ness treat­ment, and pre­ven­tive med­ica­tion for spe­cif­ic region­al diseases.

Talk to your PCP about whether pre­ven­tive med­ica­tions are right for your trip. A quick con­ver­sa­tion before you leave can save you from a very mis­er­able week abroad. 

How to Stay Healthy Dur­ing Your Trip

Prepa­ra­tion sets the foun­da­tion, but what you do dur­ing your trip mat­ters just as much. A few sim­ple habits can dra­mat­i­cal­ly reduce your risk of get­ting sick.

Food and water safe­ty. In high­er-risk areas, drink bot­tled or treat­ed water; avoid ice unless you’re con­fi­dent it’s from a safe source; eat ful­ly cooked foods; skip raw seafood or under­cooked meats; and peel fruits your­self when pos­si­ble. It sounds straight­for­ward, but these habits can make a real difference.

Pre­vent­ing mos­qui­to-borne ill­ness. Mos­qui­toes can car­ry malar­ia, dengue, Zika, and oth­er dis­eases depend­ing on your region. Use an EPA-reg­is­tered insect repel­lent, wear long sleeves and pants in high-risk areas, sleep in air-con­di­tioned or screened rooms, and use bed nets when needed.

Sun, heat, and alti­tude. Stay well-hydrat­ed, use sun­screen dai­ly, and if you’re gain­ing alti­tude, do it grad­u­al­ly. Know the warn­ing signs of heat exhaus­tion and alti­tude sick­ness — both can esca­late quick­ly if ignored.

What If You Get Sick While Trav­el­ing or After You Return?

Some trav­el-relat­ed ill­ness­es show up days or even weeks after you’ve come home. If you feel off after an inter­na­tion­al trip, don’t brush it off. See a health­care provider — and tell them where you’ve been — if you experience:

• Fever after inter­na­tion­al trav­el (this is espe­cial­ly urgent)
• Severe or per­sis­tent diarrhea
• An unex­plained rash
• An ongo­ing cough
• Yel­low­ing of the skin or eyes

Dur­ing your trip, if you devel­op a high fever, severe dehy­dra­tion, or dif­fi­cul­ty breath­ing, seek imme­di­ate med­ical care at a local facil­i­ty. Ear­ly treat­ment can pre­vent com­pli­ca­tions that become much hard­er to man­age later.

Trav­el­ing With Kids? Plan.

Trav­el­ing with chil­dren requires extra prepa­ra­tion, and the ear­li­er you start, the bet­ter. Some vac­cines aren’t rec­om­mend­ed for infants, which means plan­ning is the only way to ensure your youngest trav­el­ers are protected.

Kids may need accel­er­at­ed vac­cine sched­ules, age-spe­cif­ic dos­ing, and addi­tion­al pre­cau­tions for food and water safe­ty. If you’re trav­el­ing with an infant, you’ll also want to think through safe for­mu­la prepa­ra­tion, access to clean water, and reli­able emer­gency care at your destination.

If you’re won­der­ing whether babies can receive trav­el vac­cines, the answer depends on age and des­ti­na­tion. A trav­el med­i­cine provider can walk you through what’s safe, what’s rec­om­mend­ed, and what to watch for on the road.

What Does Trav­el Med­i­cine Cost?

Trav­el vac­cine cov­er­age varies wide­ly by insur­ance plan. Rou­tine vac­cines are often cov­ered. Trav­el-spe­cif­ic vac­cines, like those for typhoid or Japan­ese encephali­tis, may not be. Con­sul­ta­tion fees vary by provider.

It’s worth check­ing with your insur­ance car­ri­er in advance and bud­get­ing accord­ing­ly. The upfront expense is almost always less than the cost of get­ting sick abroad — between emer­gency care, missed trav­el days, and the logis­ti­cal headaches of being ill in anoth­er coun­try, the math tends to favor prevention. 

Fre­quent­ly Asked Questions

• How ear­ly should I get trav­el vac­cines? Ide­al­ly, 4 to 8 weeks before depar­ture, but even last-minute appoint­ments are worthwhile.
• Are trav­el vac­cines required for all coun­tries? No, but some des­ti­na­tions do require proof of spe­cif­ic vac­cines (such as yel­low fever) for entry. Your provider can tell you which apply to your itinerary.
• Do I need malar­ia pills? Only if your des­ti­na­tion has malar­ia risk. This is a des­ti­na­tion-spe­cif­ic con­ver­sa­tion with your provider.
• Can I bring antibi­otics just in case? In some cas­es, yes. Your provider can deter­mine whether a just-in-case antibi­ot­ic pre­scrip­tion makes sense for your trip.
• What if I’m immuno­com­pro­mised? Extra plan­ning is essen­tial. Review the CDC’s guid­ance for immuno­com­pro­mised trav­el­ers and talk to your provider well in advance. 

Inter­na­tion­al trav­el opens up the world. A lit­tle prepa­ra­tion before­hand means you can actu­al­ly enjoy it — with­out spend­ing your dream trip sick in a hotel room. Talk to your provider, get the right vac­cines, and explore!
