Travel Health Guide: Pakistan (Vaccines, Malaria, Polio Rules, and Karakoram Altitude)

Pakistan is one of a small number of destinations with a health entry-and-exit rule most travelers have never heard of: because wild poliovirus still circulates here, the government can require proof of polio vaccination when you leave the country. Beyond that, the core preparation is straightforward. As an emergency physician who treats returning travelers, the four things I tell every Pakistan-bound patient to lock down are a polio booster, typhoid vaccine, hepatitis A vaccine, and malaria prevention. The CDC lists malaria risk throughout Pakistan, typhoid risk is high (with drug-resistant strains circulating since 2016), and dengue surges after the monsoon. If you are heading to the Karakoram or Hunza Valley, add altitude planning. Most of this can be handled before you fly without a single clinic waiting room.

Overview: What Pakistan Asks of Your Body

Pakistan rewards travelers with extraordinary range, from the Mughal architecture of Lahore to the 8,000-meter giants of the Karakoram, but that range is exactly why health prep matters. A trip that mixes Lahore street food, a few days in Islamabad, and a trek toward K2 Base Camp touches three different risk environments: dense urban areas with foodborne and mosquito-borne disease, and high-altitude wilderness with thin air and limited medical access.

In my clinical experience, the travelers who get into trouble are not the ones who picked a "risky" destination. They are the ones who treated a complex itinerary like a simple one. The good news is that Pakistan's main threats, typhoid, hepatitis A, malaria, and traveler's diarrhea, are among the most preventable in travel medicine. The preparation is well-defined, and most of it is done weeks before departure.

Two scheduling notes shape everything below. First, the polio vaccine and typhoid vaccine work best when given ahead of time, so start at least two to four weeks out. Second, monsoon season (roughly July through September) drives both flooding and a post-monsoon dengue spike, so summer and early-fall travelers face higher mosquito-borne risk.

Polio: The Rule That Surprises Travelers

Pakistan is one of only two countries, alongside Afghanistan, where wild poliovirus transmission has never been stopped, according to the World Health Organization and the Global Polio Eradication Initiative. Because of this, the CDC recommends that adult travelers to Pakistan who completed their childhood polio series receive a single lifetime adult booster dose of inactivated polio vaccine (IPV).

There is a second, often-missed layer. Under WHO temporary recommendations adopted by Pakistan, long-term visitors (generally those staying more than four weeks) may be required to show proof of polio vaccination received between four weeks and twelve months before departure in order to exit the country. The documentation is recorded on an International Certificate of Vaccination or Prophylaxis (the yellow card). Rules and enforcement change, so verify current requirements with the CDC Pakistan page and official sources before you travel.

The practical takeaway: get your polio booster early, keep the documentation, and do not leave this to the last week. Polio vaccine is administered by a pharmacist, not prescribed, so it is a quick appointment rather than a doctor visit.

Typhoid and the XDR Strain You Should Know About

Typhoid fever is a serious, sometimes life-threatening bacterial infection spread through contaminated food and water, and Pakistan is a high-risk destination. The CDC recommends typhoid vaccination for most travelers to Pakistan, and there is an added reason to take it seriously here: since 2016, Pakistan has reported an ongoing outbreak of extensively drug-resistant (XDR) typhoid, first identified in Sindh province.

XDR typhoid is resistant to most oral antibiotics that once treated it reliably, which makes prevention far more valuable than treatment. Vaccination plus careful food and water habits is your front line. If typhoid is suspected during or after travel, this resistance pattern is why physicians often turn to azithromycin or injectable ceftriaxone rather than older first-line drugs. Tell any treating clinician about recent travel to Pakistan so they choose therapy with the resistance picture in mind.

Typhoid vaccine comes as an injection (good for two years) or an oral series (good for five years). Both are administered without a prescription. If you want the longer-lasting oral option, plan ahead, since the capsules are taken over about a week and must be finished before travel.

Malaria: Prevention Across the Country

Malaria risk is present throughout Pakistan, including in cities, according to CDC guidance, so antimalarial medication is recommended for essentially all travelers. The dominant species here is Plasmodium vivax, with Plasmodium falciparum also circulating, and chloroquine resistance is established, which rules out older chloroquine-based prevention.

The two antimalarials I most often prescribe for Pakistan are atovaquone-proguanil (Malarone) and doxycycline. Atovaquone-proguanil is taken daily, started one to two days before entering a risk area, and continued for seven days after leaving. Doxycycline is also daily, started two days before, and continued for four weeks after, which is a meaningful commitment that some travelers underestimate. Both require a prescription. Risk is generally lower at very high elevations, but do not assume the northern mountains are risk-free without checking your specific itinerary.

For a deeper comparison of the two main options, see our guide on Malarone vs Doxycycline and our decision guide on whether you need malaria pills. With Wandr, a clinician reviews your itinerary and calls your antimalarial in to your local pharmacy for pickup, so you can start on schedule.

Other Vaccines to Consider

Beyond polio and typhoid, build your vaccine plan around how and where you will travel.

• Hepatitis A: Recommended for essentially all travelers to Pakistan; spread through contaminated food and water.
• Hepatitis B: Recommended for many travelers, especially for longer stays, medical care, or anything involving needles, tattoos, or intimate contact.
• Rabies: Present in dogs and other animals. Pre-exposure vaccination is worth discussing if you will be in rural areas, cycling or running, working with animals, or far from reliable medical care, because post-exposure treatment can be hard to access locally.
• Japanese encephalitis: Low risk for typical short urban trips; consider it for extended stays in rural, agricultural areas.
• Cholera: Outbreaks occur; the oral cholera vaccine is worth discussing for aid workers or those heading to areas with active transmission or poor sanitation.
• Routine vaccines: Confirm MMR, Tdap, influenza, and COVID-19 are current before any international trip.

For vaccines like typhoid and hepatitis A, Wandr books your appointment at a partner pharmacy near you and a pharmacist administers them on-site, no separate doctor's visit required. Some specialized travel vaccines (such as Japanese encephalitis or rabies) may only be available at a dedicated travel clinic, so confirm availability when you plan. See our travel vaccines guidance and our dedicated typhoid vaccine guide and polio vaccine guide to map out what you need.

Dengue and Mosquito-Borne Illness

Dengue is endemic in Pakistan, with large seasonal outbreaks concentrated after the monsoon, typically from August through November, and heaviest in urban centers such as Lahore, Rawalpindi, Islamabad, and Karachi. There is no widely recommended dengue vaccine for most US travelers and no specific antiviral treatment, so prevention means avoiding bites.

The Aedes mosquitoes that spread dengue bite mainly during the day, which catches travelers off guard. Use an EPA-registered repellent (DEET 20 to 30 percent, picaridin, or oil of lemon eucalyptus), wear long sleeves and pants where practical, and treat clothing or gear with permethrin. These same measures reduce your malaria risk from the dusk-to-dawn Anopheles mosquitoes, so consistent bite protection does double duty across Pakistan.

Food, Water, and Traveler's Diarrhea

Traveler's diarrhea is the most common travel illness in South Asia, and Pakistan is no exception. The core rule holds: boil it, cook it, peel it, or skip it. Drink sealed bottled or properly treated water, skip ice of unknown origin, avoid raw salads and unpeeled fruit washed in tap water, and be cautious with dairy that may be unpasteurized.

For prevention, oral rehydration is the foundation, and over-the-counter bismuth subsalicylate (Pepto-Bismol) can reduce risk and symptoms. For treatment, because of high fluoroquinolone resistance and the XDR typhoid backdrop, azithromycin is the antibiotic I most often recommend for travelers to Pakistan, paired with loperamide for symptom control in the right situations. A short standby course you carry with you means you can act quickly instead of searching for care while ill. Our guide on traveler's diarrhea antibiotics explains how this works. With Wandr, a clinician can call a standby antibiotic in to your local pharmacy before you leave.

Worth a separate mention: hepatitis E is waterborne and present in the region, has no vaccine available in the US, and is particularly dangerous in pregnancy, which is one more reason rigorous water precautions matter here.

Altitude in the North: Karakoram, Hunza, and Beyond

Northern Pakistan holds some of the highest and most dramatic terrain on earth, including K2, the Karakoram Highway, Hunza Valley, Fairy Meadows, Deosai Plateau, and the Khunjerab Pass at roughly 4,693 meters. Altitude illness becomes a real risk above about 2,500 meters, and these routes climb well beyond that.

Acute mountain sickness shows up as headache, nausea, fatigue, and poor sleep. The prevention playbook is ascend gradually, avoid going too high too fast, stay hydrated, and recognize that fitness does not make you immune. Acetazolamide can speed acclimatization and reduce symptoms, and I commonly prescribe it for travelers heading to high passes or trekking objectives. The non-negotiable rule is that worsening symptoms mean you descend. For trip-level planning, see our altitude sickness guide. A Wandr clinician can call acetazolamide in to your pharmacy as part of your pre-trip prep.

Heat, Air Quality, and Other Practical Risks

Pakistan's summers are extreme. Cities in Sindh and southern Punjab regularly push into dangerous heat, and Jacobabad ranks among the hottest inhabited places on the planet. If you travel in late spring or summer, plan for heat: hydrate aggressively, schedule activity for early morning, and learn the warning signs of heat exhaustion. Winter brings a different problem to the Punjab plains, where Lahore frequently records some of the world's worst air quality, which matters if you have asthma or other respiratory conditions. Pack any inhalers or respiratory medications you rely on, and consider a high-filtration mask during smog season.

Travel Insurance for Pakistan

I rarely tell travelers insurance is optional, and for Pakistan I am emphatic about it. Quality medical care is concentrated in major cities, and the most spectacular parts of the country, the northern mountains, are exactly where you are farthest from it. A serious illness or injury on a Karakoram trek can require helicopter evacuation, which is extraordinarily expensive without coverage. Choose a policy that explicitly includes emergency medical care and medical evacuation, and confirm it covers your specific activities if you plan to trek or climb.

Pre-Trip Health Checklist for Pakistan

• Start vaccines two to four weeks before departure (polio booster, typhoid, hepatitis A at minimum)
• Keep your polio vaccination documentation, especially for stays over four weeks
• Fill your antimalarial and know when to start it
• Carry a standby course of azithromycin and oral rehydration salts
• Pack repellent (DEET or picaridin) and permethrin-treated clothing
• Add acetazolamide if heading above 2,500 meters
• Buy travel insurance with medical evacuation coverage
• Verify current entry and exit requirements on the CDC Pakistan page before you fly

Frequently Asked Questions

Do I need malaria pills for Pakistan?

Yes. The CDC lists malaria risk throughout Pakistan, including in cities, so antimalarial medication is recommended for essentially all travelers. Atovaquone-proguanil and doxycycline are the usual choices because chloroquine resistance is established. Start before you arrive and continue after you leave per your medication's schedule.

Is the polio vaccine really required to travel to Pakistan?

The CDC recommends a one-time adult polio booster for travelers, and Pakistan may require proof of polio vaccination to exit the country for visitors staying longer than about four weeks. The dose should generally be received four weeks to twelve months before departure and documented on the yellow vaccination card. Verify current rules before you travel.

What vaccines do I need for Pakistan?

At minimum, plan for a polio booster, typhoid, and hepatitis A. Depending on your trip, also consider hepatitis B, rabies, Japanese encephalitis, and cholera, and confirm routine vaccines like MMR, Tdap, influenza, and COVID-19 are current. A clinician can tailor the list to your itinerary.

Is the water safe to drink in Pakistan?

No, tap water is not considered safe for travelers. Drink sealed bottled or properly treated water, avoid ice of unknown origin, skip raw produce washed in tap water, and be cautious with unpasteurized dairy. These habits prevent typhoid, hepatitis A and E, and traveler's diarrhea.

What is XDR typhoid and should I worry about it?

XDR (extensively drug-resistant) typhoid is a strain resistant to most oral antibiotics that has circulated in Pakistan since 2016. It makes prevention through vaccination and safe food and water habits especially important. If typhoid is suspected, clinicians often use azithromycin or ceftriaxone; always mention recent travel to Pakistan so treatment matches the resistance pattern.

Do I need altitude medication for northern Pakistan?

If your itinerary goes above roughly 2,500 meters, which includes Hunza, the Karakoram Highway, Fairy Meadows, and high passes like Khunjerab, altitude sickness is a real risk. Gradual ascent is the main prevention, and acetazolamide can help acclimatization. Discuss a prescription with a clinician before you go.

When should I start preparing for a trip to Pakistan?

Begin four to six weeks before departure if possible. Some vaccines need lead time, the oral typhoid series takes about a week to complete, and antimalarials must be started before you arrive. Earlier is always better, but a clinician can still help even on a compressed timeline.
