Getting sick during a trip to China is not inevitable — but it's common enough that ignoring the risk is naive. The good news: most health issues travelers encounter are preventable with basic precautions, and the ones that aren't are usually manageable if you're prepared.
This guide covers the main risk categories, what actually matters versus what's overhyped, and what to do if you get sick anyway.
The Most Common Health Issues for Tourists in China
Before diving into prevention, it helps to know what you're actually guarding against.
Digestive problems are the most frequent complaint — stomach upset, diarrhea, or food poisoning from eating unfamiliar food, bacteria your gut hasn't encountered before, or simply eating at places with inconsistent hygiene. This affects a large share of first-time visitors to China and most other Asian countries.
Respiratory issues are the second most common. Air quality in many Chinese cities, particularly in winter and in inland industrial areas, can trigger or worsen respiratory symptoms. People with asthma or allergies tend to notice this most.
Dehydration and heat exhaustion are real risks in summer, especially if you're doing a lot of walking in cities like Chongqing, Guangzhou, or Xi'an during peak heat months.
Minor injuries — twisted ankles on uneven paving, blisters from more walking than expected — aren't illness exactly, but they take people off their feet more often than exotic diseases.
Serious infectious diseases that tourists sometimes worry about — like avian flu or severe GI infections — are statistically rare for short-stay visitors who stick to regular tourist areas and eat at reasonably clean establishments. Take them seriously, but they're not the main event.
Food and Water: What Actually Matters
Tap water
Don't drink tap water in China. This isn't negotiable and it isn't a matter of personal risk tolerance. The tap water in Chinese cities is not treated to drinking-safe standards for most people, including locals. Bottled water is cheap, widely available, and what everyone uses.
Use bottled or boiled water for:
- Drinking
- Brushing your teeth
- Making coffee or tea (if you're doing it yourself and not using a kettle that boils)
Ice in restaurants at most mid-range and above establishments is made from purified water and is generally fine. Street stalls and very low-end restaurants are more variable.
Food
The standard guidance is to eat at places that look busy and clean — not because dirtier-looking places are automatically dangerous, but because volume turnover means food is fresher and staff are more practiced.
A few specific things to watch:
Street food: Much of it is fine and cooked fresh in front of you — that's actually safer than pre-made food sitting out. Skewers, scallion pancakes, dumplings cooked to order: generally lower risk. Raw-adjacent items, cold dishes, or anything that's been sitting in ambient temperature for a while: more caution.
Raw or undercooked shellfish: Higher risk across China, particularly in inland cities far from the coast where freshness chains are less reliable. If you're somewhere like Chengdu or Wuhan, be more careful with shellfish than you would be in Shanghai or Qingdao.
Cold appetizers in small restaurants: These are a common source of digestive upset. The soy-marinated cold dishes (凉菜) at cheap local restaurants aren't inherently dangerous, but they sit at room temperature and the prep varies.
Fruit: Fine to eat, but wash it or peel it. Fruit sold at stalls is generally fine; the concern is surface contamination, not the fruit itself.
Hands
Wash your hands before eating, particularly in crowded tourist areas. Hand sanitizer is useful and widely sold. This sounds basic but it handles a lot of transmission risk.
Air Quality: Know Before You Go
China's air quality has improved significantly over the past decade, but it's still a real factor in some cities and seasons.
The worst times and places:
- North China in winter (November–March): Beijing, Xi'an, Shenyang, and other northern cities can have extended periods of poor air, particularly during heating season when coal combustion adds to traffic and industrial pollution.
- Chengdu and Chongqing: The basin geography traps particulates. Air quality here can be poor year-round but is typically worse in winter and autumn.
Better situations:
- Coastal cities in summer: Shanghai, Guangzhou, Shenzhen, and Qingdao tend to have better air in summer due to sea breezes and rainfall.
- Yunnan and southwest highlands: Generally good air quality, one reason Kunming and Dali are popular with people who are sensitive to pollution.
If you have asthma, COPD, or significant respiratory sensitivity:
- Check the AQI before you travel (IQAir and AirVisual have real-time data for Chinese cities)
- Bring your regular inhaler or medication
- Consider an N95 mask for days above 150 AQI — not surgical masks, which don't filter fine particles meaningfully
- Know where the nearest international-department hospital is before you go
For most healthy travelers, air quality in China is a minor nuisance, not a health threat. For people with existing respiratory conditions, it's worth planning around.
Vaccines: What You Actually Need
For most travelers to major Chinese cities, no special vaccines beyond routine ones are required.
What's recommended:
- Hepatitis A and B (standard for most international travel to Asia)
- Typhoid (recommended for adventurous eaters or rural travel)
- Routine vaccines: tetanus/diphtheria, MMR, flu
What may be considered depending on your itinerary:
- Japanese encephalitis: relevant if you're spending extended time in rural areas, particularly in summer. Urban tourists don't need it.
- Rabies pre-exposure: relevant if you're doing outdoor work, wildlife exposure, or extensive rural travel. Not relevant for typical city tourists.
COVID-19: Standard per whatever the current entry and health requirements are in 2026. Check current guidelines from your country's foreign affairs department before travel.
Consult a travel medicine clinic or your doctor before you go, particularly if you're visiting rural areas, doing outdoor activities, or traveling for longer than 2–3 weeks.
Pollution and General Environment
A few things that affect health that people don't always think about:
Altitude: If you're visiting Tibet, Yunnan highlands, or western China, altitude sickness is a real risk. Lhasa sits at 3,650 meters; acclimatization takes time. If you're headed to high altitude, plan extra days, avoid strenuous activity on arrival, and know the symptoms of acute mountain sickness.
Heat: Summer in southern and central China is genuinely hot and humid. Guangzhou in July is oppressive. Carry water, wear loose clothing, take breaks indoors, and don't underestimate how much energy you burn walking in heat.
Sun: Southern China, particularly Yunnan and Hainan, has strong UV. Use sunscreen.
Noise: Chinese cities, particularly street markets and entertainment districts, are loud. Not a health emergency, but worth knowing if you're sensitive to it.
Practical Kit for Staying Healthy
Pack the following:
- Water purification tablets or filter (useful for backup, not daily use — bottled water is the default)
- Oral rehydration salts — if you do get digestive trouble, rehydration matters more than most medications
- Loperamide (Imodium) — for acute diarrhea; widely available in China too, but useful to have
- Activated charcoal capsules — some travelers swear by these for food poisoning; the evidence is modest but they're harmless
- Antihistamine — air quality and unfamiliar plants can trigger allergic reactions
- Your regular prescriptions with enough supply plus a buffer — see our guide on managing medications in China
- Travel insurance that covers emergency medical — not optional if you're being sensible
What to Do If You Get Sick Anyway
Even with good precautions, some people get sick. Here's the practical path:
Minor digestive upset: Stay hydrated, rest, eat plain foods (rice, plain noodles, congee), use ORS if you're losing fluids. Most cases resolve in 24–48 hours.
Anything with fever above 38.5°C, blood in stool, severe abdominal pain, or symptoms that aren't improving after 48 hours: Go to a hospital. Major cities all have international departments at public hospitals and dedicated foreign-patient clinics. These are used to seeing travelers and can communicate in English.
Respiratory symptoms: If you have fever + cough + breathing difficulty, get checked. China's respiratory healthcare is strong. Don't tough it out.

The Short Version
- Don't drink tap water
- Eat at busy places, be cautious with cold/raw items and shellfish
- Check air quality if you're sensitive; bring an N95 if you're visiting northern China in winter
- Get Hep A, Hep B, and typhoid vaccines if you haven't
- Pack ORS, loperamide, and your regular medications
- Know where the nearest hospital is before you need it
China is not particularly dangerous from a health perspective for most short-stay tourists. A bit of preparation handles most of the risk. And if something does go wrong, the country's hospital system — at least in the major cities — is capable of handling it.
