System overview
Thailand operates a dual public and private system. The public network sits under the Ministry of Public Health and runs from rural district hospitals up to large urban tertiary centres such as Siriraj and Chulalongkorn in Bangkok [1]. Universal Coverage (often called "30-baht") protects Thai citizens; foreign residents generally cannot use it unless enrolled through formal employment and the Social Security Office. Most Western relocators rely on the private sector, which is the largest and most internationally accredited in Southeast Asia. As of 2026 Thailand hosts the highest number of JCI-accredited organisations in the region [2].
Hospitals to know
Bangkok
- Bumrungrad International, Sukhumvit Soi 3. A 580-bed tertiary hospital that has held continuous JCI accreditation since 2002, the first hospital in Asia to do so. Strong cardiology, oncology, orthopaedics and a dedicated international patient centre with interpreters in over 20 languages [3].
- Bangkok Hospital (BDMS), Soi Soonvijai. Flagship of the BDMS network, JCI accredited, full range of specialities including a cardiac centre, neuro centre and cancer institute [4].
- Samitivej Sukhumvit, Soi 49. JCI accredited, well regarded for general internal medicine, paediatrics, geriatric care and rehabilitation [5].
Chiang Mai
- Bangkok Hospital Chiang Mai. Part of the BDMS group, the most expat-oriented private hospital in the north, with cardiology, oncology and orthopaedic centres and English-speaking staff [6].
- Chiang Mai Ram Hospital. Long-established private hospital, broad specialities, generally cheaper than the Bangkok Hospital brand and widely used by long-stay foreigners [7].
Routine care and chronic disease management
Booking a GP or specialist is generally walk-in or same-week at the private hospitals named above. Sub-specialists (endocrinology, cardiology, rheumatology) are available without referral. For someone managing hypertension, high cholesterol or type 2 diabetes, expect that:
- Most first-line agents are stocked. Atorvastatin, rosuvastatin, amlodipine, losartan, telmisartan, metformin, sitagliptin, empagliflozin, dapagliflozin and insulin glargine are all available, often as both originator brands and Thai or Indian generics [3].
- Originator brands cost noticeably more than generics. Many residents split prescriptions, taking originator brands for narrow-therapeutic-index drugs and generics for routine cover.
- Continuity is straightforward: bring a written summary from your home clinician with diagnoses, current medications, doses and recent lab values, plus 30 to 90 days of medication to cover the transition.
Pharmacy and personal medication
Pharmacies are common and competent. Many medicines that need a prescription in Europe you can buy over the counter in Thailand, including most antihypertensives, statins and basic antibiotics, though pharmacists may ask for a recent prescription for repeat dispensing. Controlled drugs (benzodiazepines, opioids, stimulants, certain sleep aids) face tight restrictions. You can generally import up to 30 days' supply of prescription medicines; carry the original prescription and a doctor's letter. Psychotropic and narcotic substances need prior authorisation from the Thai FDA [1,8].
Vaccinations
CDC and WHO recommend that long-term residents be up to date on routine vaccines (MMR, dTaP, varicella, pneumococcal, shingles and seasonal influenza) plus hepatitis A, hepatitis B and typhoid. Get Japanese encephalitis vaccination if you're a resident, staying a month or longer, or visiting rural areas. The CDC also recommends rabies pre-exposure vaccination for anyone living in Thailand long term because of the large stray dog population and uneven access to post-exposure immunoglobulin outside major cities [9,10]. Yellow fever vaccination is required only if arriving from a country with risk of transmission.
Endemic infectious risks
- Dengue is endemic countrywide, year round, peaking in the rainy season (roughly June to October). Outbreaks recur every few years. Use repellent and screens; there is no specific antiviral treatment [9].
- Malaria risk is concentrated along forested borders with Myanmar and Cambodia, in parts of Kanchanaburi, Tak, Trat and Ranong. Bangkok, Chiang Mai city, Phuket and the main beach areas are not malaria zones [9].
- Rabies remains present in stray dogs and cats; any bite or scratch from an unvaccinated animal should be treated as an emergency, washed immediately with soap and water, and followed by post-exposure prophylaxis at a hospital that stocks immunoglobulin (Bumrungrad, Bangkok Hospital, Samitivej, Chiang Mai Ram all stock it) [10].
- Hand, foot and mouth disease is common in young children; less relevant for older relocators unless living with grandchildren.
Water and food
Tap water in Bangkok is treated and chlorinated but is not generally consumed without further filtration; bottled or filtered water is the norm. Ice in reputable restaurants, hotels and cafes is industrially produced and safe; street stalls vary [8].
Air quality
PM2.5 affects anyone with cardiovascular or respiratory conditions. Northern Thailand, including Chiang Mai and Chiang Rai, experiences severe agricultural burning haze from roughly February to April, with PM2.5 routinely exceeding WHO 24-hour guidelines by a wide margin. Bangkok has a milder but still elevated dry-season pollution peak in December to March [11]. Practical mitigations: indoor air purifiers with HEPA filters, N95-equivalent masks outdoors on bad days, and tracking daily AQI before exercise.
Insurance
- Thai Social Security (SSO) covers formally employed foreigners; benefits are basic and tied to a designated public hospital.
- Private Thai insurers (AIA, Bupa Thailand, Pacific Cross, Luma) offer plans with direct billing at major private hospitals. Premiums rise steeply after 60 and insurers usually exclude pre-existing conditions for the first one to two years or permanently.
- Expats in Thailand commonly use international insurers like Cigna Global, Allianz Care, AXA Global Healthcare, William Russell and IMG. None is universally best; compare on geographic scope (does it include the US?), annual limit, outpatient cover, chronic-condition handling, and age-band premium escalation. For someone 60+ with existing conditions, full underwriting before signing is essential.
Emergencies
The national medical emergency hotline is 1669 for ambulance, 191 for police and 199 for fire; tourist police on 1155 [1]. Response times in Bangkok and major cities are reasonable; in rural areas private hospital ambulances (Bangkok Hospital, Bumrungrad) are often faster and the only realistic option for a foreigner needing English. Air or ground medevac to Bangkok is the regional standard for serious cases originating in Laos, Cambodia or Myanmar; from inside Thailand, transfer between provincial and Bangkok hospitals is straightforward.
