Travel Health Guide: China — Vaccines, Altitude in Tibet, Medication Import Rules, and What Most US Travelers Get Wrong

Most US travelers heading to China think the trip is a simple vaccine update plus a stomach plan. The reality is more layered. China combines a modern public health system, regional disease pockets, the world's most restrictive medication import rules among major destinations, and Tibet, a region where roughly one in two arriving tourists develops acute mountain sickness within hours of landing. According to the CDC, all travelers to China should be current on routine vaccines, hepatitis A, and typhoid, with Japanese encephalitis and rabies considered for higher-risk itineraries. Travelers heading to Lhasa or any Tibetan highland should plan for altitude sickness prevention well before departure. And anyone carrying common US prescriptions like Adderall, Vyvanse, or codeine combinations needs to plan around a hard border restriction, not work around it. This guide walks through every layer.

What every US traveler to China needs

China presents three concurrent travel health risks: vaccine-preventable disease in rural and mixed-itinerary trips, altitude illness on any itinerary that includes Tibet or western highland provinces, and medication restrictions that can result in arrest, denial of entry, or confiscation at customs. None of these are theoretical. The CDC's Yellow Book lists hepatitis A and typhoid as standard pre-travel vaccines for China, and Japanese encephalitis as a strong consideration for any traveler staying longer than one month or spending time in rural areas. The State Department's current travel advisory places mainland China at Level 2 (Exercise Increased Caution) and explicitly warns about arbitrary enforcement of local laws, which extends to medication possession.

In short, China rewards travelers who plan health logistics months in advance and punishes those who treat it like a generic Asia trip.

Routine and recommended vaccines for China

The CDC's current recommendation for travelers to China starts with routine vaccines. Every traveler should be up to date on measles-mumps-rubella (MMR), diphtheria-tetanus-pertussis (Tdap), varicella, polio, and the seasonal influenza vaccine. The CDC also continues to recommend COVID-19 vaccination for international travel.

Beyond routine, three travel-specific vaccines are commonly indicated for China itineraries.

Hepatitis A is recommended for nearly all travelers. Hepatitis A is transmitted through contaminated food and water, both of which are difficult to fully control even at upmarket hotels and restaurants. Two doses spaced six months apart provide long-term protection, and a single dose given at least two weeks before departure offers strong short-term coverage.

Typhoid is recommended for travelers visiting smaller cities, rural areas, or staying with friends and relatives, and for any adventure travel itinerary. Typhoid risk in China's largest cities (Beijing, Shanghai, Guangzhou, Chengdu) is low, but the moment an itinerary moves to smaller cities or rural provinces, risk rises sharply. Both an injectable typhoid vaccine and an oral capsule version exist; the injectable is more practical for last-minute travel because it produces protection in about two weeks rather than four.

Japanese encephalitis (JE) is a mosquito-borne viral infection that can cause severe brain inflammation. The CDC recommends the JE vaccine for travelers staying longer than one month, and for shorter-stay travelers who plan rural activities, outdoor evening exposure, or accommodations without air conditioning or screens. The vaccine is given as two doses 28 days apart (an accelerated 7-day schedule is approved for adults aged 18 to 65), so it has to be started weeks before departure.

Rabies is the wildcard. The CDC explicitly warns that any dog or mammal bite anywhere in China, including in urban centers, should be treated as a high-risk rabies exposure. Pre-exposure rabies vaccination is now a shortened two-dose regimen given one week apart, which has lowered the barrier for travelers. The reason pre-exposure matters: it eliminates the need for rabies immunoglobulin after a bite. Rabies immunoglobulin is often unavailable in rural China, and finding it can require evacuation to a major city, sometimes losing days of a tight itinerary.

For vaccines like hepatitis A, typhoid, and Japanese encephalitis, Wandr books your appointment at a partner pharmacy near you. The pharmacist administers your travel vaccines on-site, with no separate doctor visit required.

Tibet and the altitude question

If your China itinerary includes Tibet, the conversation changes. Lhasa sits at 3,658 meters (11,995 feet) above sea level, which is well above the 2,500-meter threshold where acute mountain sickness (AMS) commonly develops. Published cross-sectional studies of tourists arriving in Lhasa report symptom rates around 50% within the first 12 to 24 hours, and roughly a quarter of travelers in those studies used acetazolamide (Diamox) for prevention.

Symptoms of AMS include headache, nausea, fatigue, dizziness, and disrupted sleep. They typically begin 6 to 12 hours after arrival at altitude. Most cases resolve within 24 to 48 hours with rest, hydration, and avoiding alcohol or sleeping pills, but a minority progress to high-altitude pulmonary edema (HAPE) or high-altitude cerebral edema (HACE), both of which are medical emergencies that require immediate descent.

Acetazolamide is the standard prevention medication. The typical dose is 125 mg twice daily, started one day before ascent and continued for the first two days at altitude. It works by accelerating acclimatization through increased ventilation (about 10 to 20% more minute ventilation), which improves blood oxygenation. A 2025 randomized trial of an extended-release 500 mg once-daily formulation confirmed effective AMS prevention with better adherence than the twice-daily regimen.

Other parts of China to keep in mind for altitude:

• Shangri-La (Yunnan): 3,200 meters. Frequent AMS reports.
• Jiuzhaigou (Sichuan): 2,000 to 3,400 meters across the park. Borderline risk.
• Kashgar to Karakoram Highway (Xinjiang): passes climb above 4,700 meters.
• Everest Base Camp (north side, Tibet): 5,200 meters. High-risk; descent plans are essential.

For prescription medications like acetazolamide for altitude sickness prevention, Wandr's clinicians call the prescription in to your local pharmacy for pickup before your trip. This matters more for China than for most destinations because filling acetazolamide in Lhasa is unreliable and can delay your acclimatization plan.

Traveler's diarrhea: still the most common problem

Despite improved sanitation in China's major cities, traveler's diarrhea (TD) remains the single most common health issue among US visitors. Estimated attack rates for short-term travelers to China range from 10% to 20% depending on itinerary, food choices, and region. The risk is higher in rural areas, smaller cities, and during street food-heavy itineraries.

A reasonable TD plan for China includes three components.

First, food and water choices. Bottled or boiled water only. Avoid ice unless made from bottled water. Avoid raw vegetables that may have been rinsed in tap water. Hot, freshly cooked food from busy vendors is generally lower risk than reheated buffet food at hotels.

Second, an on-board treatment plan. Loperamide (Imodium) controls symptoms quickly. Bismuth subsalicylate (Pepto-Bismol) helps with mild cases and offers modest prevention if taken before meals. Pack both.

Third, a prescription antibiotic for moderate to severe cases. Azithromycin is the CDC's preferred antibiotic for travel to most of Asia, including China, because of growing fluoroquinolone resistance in Campylobacter, a common TD pathogen in the region. Azithromycin is dosed as 1,000 mg as a single dose or 500 mg daily for three days. For travelers with kidney issues, fluoroquinolone allergy, or significant Campylobacter concerns, the prescriber can adjust accordingly.

For prescription antibiotics for traveler's diarrhea, our clinicians call the prescription in to your local pharmacy for pickup before your departure date.

Malaria: low risk for most, real risk for a few

China was declared malaria-free by the World Health Organization in 2021 after four consecutive years with zero local cases, a public health achievement decades in the making. For nearly every US traveler today, including those visiting Beijing, Shanghai, Xi'an, Chengdu, and most mainstream tourist itineraries, malaria prophylaxis is not indicated.

The narrow exception is travelers visiting the rural southern border regions of Yunnan province, which share borders with Myanmar, Laos, and Vietnam. While China itself remains malaria-free, imported malaria cases continue to arrive across these borders, and roughly 300 imported cases per year have been reported in Yunnan. For backpackers, ecotourists, or longer-stay travelers planning extended time in rural southern Yunnan border counties, a CDC consultation is warranted to determine if antimalarials like Malarone (atovaquone-proguanil) or doxycycline are appropriate. Mefloquine is generally avoided in this region because of historical resistance patterns.

For most other Chinese itineraries, mosquito-bite prevention (DEET or picaridin repellent, long sleeves at dawn and dusk, treated clothing) is sufficient and also reduces risk of dengue and Japanese encephalitis.

Rabies risk in urban and rural China

Rabies deserves its own section because the risk profile in China is unusual. Unlike most developed countries where rabies is limited to wildlife in rural areas, in China rabies cases are reported in urban and suburban areas, and the primary reservoir is unvaccinated domestic dogs. Stray dogs are common in many smaller cities and rural areas, and even friendly-looking dogs in urban parks can pose risk.

Post-exposure prophylaxis (PEP) in China is widely available in city hospitals but depends on a series of vaccine doses and, for unvaccinated patients, rabies immunoglobulin (RIG) injected at the wound site. RIG can be in short supply outside major urban hospitals.

The pre-exposure rabies vaccine has been simplified. Recent CDC and WHO recommendations support a two-dose pre-exposure schedule (days 0 and 7), down from the older three-dose, three-week protocol. Pre-exposure vaccination still requires post-exposure boosters after any bite, but it eliminates the need for RIG, which is the harder element to source.

Practically: families traveling with children (who are at higher risk of dog bites), travelers planning extended rural stays, cyclists, runners, and anyone working with animals should strongly consider pre-exposure rabies vaccination before China travel.

Schistosomiasis and freshwater exposure

Schistosomiasis is a parasitic infection caused by Schistosoma japonicum in China, transmitted when larval forms in contaminated freshwater penetrate skin. The Yangtze River basin, particularly Dongting Lake (Hunan) and Poyang Lake (Jiangxi), has historically been the highest-risk area. China has made enormous progress on schistosomiasis control, achieving transmission control nationwide by 2015, but molecular surveillance studies between 2015 and 2019 confirmed the intermediate snail host (Oncomelania hupensis) still persists along the Yangtze.

For travelers, the practical rule is simple: avoid swimming, wading, or having extended skin contact with freshwater in the Yangtze River basin lakes and tributaries. Chlorinated pools and seawater are safe. If accidental freshwater exposure occurs, towel off vigorously (the parasite needs sustained contact to penetrate) and discuss symptoms (fever, rash, abdominal pain weeks later) with a travel medicine provider.

Air quality: the underrated risk

China's largest cities still experience seasonal PM2.5 levels that exceed WHO guidelines. Winter months (November through February) are typically worst in northern cities like Beijing, Tianjin, and Xi'an due to heating emissions and atmospheric inversions. For travelers with asthma, COPD, or cardiovascular disease, air quality should be part of the planning conversation.

Practical mitigation includes N95 or KN95 masks during high-PM days, avoiding outdoor exercise during pollution spikes, and ensuring an updated asthma action plan with rescue inhalers and, where indicated, oral corticosteroids on hand. The Air Quality Index (AQI) is widely reported within China and on apps; readings above 150 typically warrant precaution for sensitive groups.

Medication import rules: the part travelers underestimate

This is the section where well-prepared travelers still get caught off guard. China enforces strict controls on imported medications, and the consequences for noncompliance are not theoretical. Per current State Department guidance, "China restricts importation of medications common in the United States, including amphetamine medications like Vyvanse and Adderall. Exercise extreme caution when carrying these medications." The CDC's Yellow Book chapter on prohibited and restricted medications lists the consequences plainly: "Consequences for being caught traveling internationally with a prohibited or restricted medication include delay in travel, confiscation of the medication, denial of entry, or arrest."

Medications and ingredients that commonly cause problems at Chinese customs include:

• Amphetamine-based stimulants: Adderall, Vyvanse, Dexedrine. These are not legal to bring into China, even with a US prescription.
• Opioid pain medications: oxycodone, hydrocodone, codeine combinations (Tylenol #3), tramadol. Heavily restricted; documentation requirements are strict.
• Methylphenidate (Ritalin, Concerta): restricted with high documentation burden.
• Some sleep medications and benzodiazepines: Ambien, Xanax, Valium. Permitted in small quantities with prescription, but documentation is essential.
• Certain cold and allergy combinations containing pseudoephedrine: scrutinized at customs.

Before departure, travelers carrying any controlled-substance prescription should: (1) confirm current status with the Chinese embassy or nearest Chinese consulate; (2) carry the prescription bottle in original packaging with the pharmacy label intact; (3) carry a written prescription from the prescribing clinician including the generic name; (4) bring a signed letter from the prescriber explaining medical necessity. Even with all of this, amphetamine stimulants like Adderall remain functionally inadmissible. Travelers who depend on these medications should consult their prescriber about temporary alternatives.

Pre-trip timing: when to start

A reasonable timeline for China travel health prep looks like this.

Eight weeks before departure: schedule a pre-trip consult. This is when Japanese encephalitis (28-day standard schedule) and rabies (two doses, days 0 and 7) need to start, and when typhoid (oral) and hepatitis A need to be administered to reach full effectiveness.

Four weeks before departure: start any accelerated vaccine schedules. Confirm medication import status for any prescription you take regularly.

Two weeks before departure: pick up acetazolamide (if Tibet is on the itinerary), azithromycin or other TD antibiotics, loperamide, Pepto-Bismol, DEET-based repellent. Verify travel insurance covers China including medical evacuation, which is critical for Tibet, Xinjiang, and other remote regions.

Three to seven days before departure: pack medications in original packaging with prescription documentation. Take a phone photo of every label.

You can complete most of this through Wandr without a separate travel clinic visit. The pre-trip health check is free, and our clinicians can prescribe what's appropriate, while vaccine appointments are booked online at a partner pharmacy near you.

City-specific health notes

Beijing (44 m / 144 ft): low altitude. Winter air pollution is the main concern. Tap water is not safe; bottled water only. Hospital quality is high in international clinics.

Shanghai (4 m / 13 ft): low altitude, generally lower TD risk than rural China. International hospitals available. Yangtze delta freshwater exposure should be avoided.

Chengdu (500 m / 1,640 ft): gateway to Tibet and to Jiuzhaigou. Useful staging point for altitude acclimatization. Spicy Sichuan food triggers higher rates of mild GI upset, even when food is safe.

Lhasa, Tibet (3,658 m / 11,995 ft): see altitude section. Plan acetazolamide prophylaxis. Consider arriving by overland transit (train from Xining) for gradual acclimatization rather than flying direct.

Kunming (1,890 m / 6,201 ft): mild altitude. Gateway to Yunnan border regions where malaria consultation may apply.

Guangzhou and Shenzhen (subtropical, sea level): dengue activity has been reported in southern China during summer and fall. Mosquito-bite precautions matter.

Xi'an (400 m / 1,312 ft): low altitude, low health risk beyond standard TD precautions. Winter air quality can be poor.

What to pack

A reasonable travel health kit for China includes:

• Prescription antibiotic for TD (azithromycin preferred)
• Loperamide (Imodium)
• Bismuth subsalicylate (Pepto-Bismol chewables)
• Oral rehydration salts
• Acetazolamide if Tibet is included
• DEET 20-30% or picaridin 20% insect repellent
• Hand sanitizer (60%+ alcohol)
• N95 or KN95 masks (3 to 5)
• Prescription medications in original bottles with prescription documentation
• Written prescription copies (including generic names) and prescriber contact info
• Travel insurance card and emergency contact numbers
• Sunscreen SPF 30+ for high-altitude exposure

When to see a doctor in China

Most travel health issues in China can be managed with the medications you brought. Seek medical evaluation if you develop:

• Severe diarrhea with blood, high fever, or signs of dehydration that persist after 24 hours of self-treatment
• Symptoms of high-altitude pulmonary edema (severe shortness of breath at rest, frothy or pink sputum, persistent cough at altitude) or high-altitude cerebral edema (confusion, ataxia, severe headache unresponsive to medication) at altitude. These require immediate descent and medical care.
• Any animal bite, scratch, or saliva exposure to broken skin
• Fever above 102°F (38.9°C) lasting more than 48 hours
• Significant respiratory symptoms with chest pain or low oxygen
• Severe allergic reactions

International hospitals are available in Beijing, Shanghai, Chengdu, Guangzhou, and several other major cities; United Family Hospitals and Parkway Health are commonly used by US travelers. Outside major cities, care quality varies significantly, and evacuation to a major city or to Hong Kong may be necessary for serious conditions, which is why travel insurance with medical evacuation coverage is essential for China.

Frequently asked questions

Do US citizens need a yellow fever vaccine for China? Only if you are arriving from a country with risk of yellow fever transmission (parts of Africa and South America). Direct US arrivals do not need yellow fever vaccination. If your itinerary routes through a yellow fever country, you must present proof of vaccination at Chinese customs.

Is China still malaria-free? Yes. The WHO certified China malaria-free in 2021 after four consecutive years of zero locally transmitted cases. The only practical exception for travelers is rural southern Yunnan province border areas, where imported cases continue to arrive across the borders with Myanmar, Laos, and Vietnam.

Can I bring my Adderall to China? No. Amphetamine-based stimulants including Adderall, Vyvanse, and Dexedrine are not legal to import into China, even with a valid US prescription. Travelers who depend on these medications should consult their prescriber about temporary alternatives or non-stimulant ADHD treatments before departure.

How early should I get the rabies vaccine before a China trip? The current pre-exposure rabies vaccine schedule is two doses given seven days apart, so it can be completed in eight days. Allow at least two weeks before departure to complete the schedule comfortably and account for scheduling delays.

Is the tap water safe to drink in Beijing or Shanghai? No. Even in major cities, tap water is not considered safe for direct consumption by international travelers. Use bottled or boiled water for drinking and brushing teeth. Avoid ice unless you know it was made with bottled or filtered water.

How long do I need to be at altitude in Tibet before I'm acclimatized? Most travelers acclimatize substantially over two to four days at altitude. Acetazolamide accelerates this process. The first 24 to 48 hours after arrival in Lhasa are when AMS symptoms peak; if symptoms worsen after 48 hours or include shortness of breath at rest or confusion, descend immediately and seek medical care.

What's the most common health problem US travelers report in China? Traveler's diarrhea, by a wide margin. Attack rates range from 10% to 20% depending on itinerary and food choices. A prepared TD kit (loperamide, Pepto-Bismol, oral rehydration salts, and a prescription antibiotic) handles most cases without requiring medical care abroad.

Do I need Japanese encephalitis vaccine if I'm only going to Beijing and Shanghai? Probably not. JE is rare in major Chinese urban centers and primarily transmitted in rural rice-growing areas. The CDC recommends JE vaccine for travelers staying more than one month, or for shorter rural-heavy itineraries during transmission season (typically summer and fall in much of China).

Is dengue a risk in China? Yes, particularly in southern provinces (Guangdong, Yunnan, Fujian) during summer and fall. There is no dengue vaccine widely available for US travelers without prior infection. Mosquito-bite prevention with daytime repellent application is the primary defense.
