Pregnancy in Thailand: Zika Risk, Dengue, and Antenatal Care
Thailand carries active Zika and dengue risks for pregnant travellers. Know the mosquito precautions, private hospital costs, and medication import rules before you fly.
What changes when you travel to Thailand during pregnancy
Thailand has active Zika virus and dengue transmission year-round, both of which carry specific risks during pregnancy[2][1]. Bangkok's heat index regularly exceeds 40°C in the dry season[7], tap water is not safe to drink, and the country has no reciprocal public healthcare agreement with most nationalities, meaning all private obstetric care is paid out of pocket[10].
This guide covers medication import rules under Thailand's Drugs Act[4], how to find an obstetrician or maternal-fetal medicine (MFM) specialist at private hospitals, what to do if you need emergency obstetric care, and the Thai phrases clinicians need to know your situation. Storing your clinical summary in Nomedic as an International Patient Summary (IPS) removes the need to reconstruct your history verbally at every appointment.

Key risks
Key risks for pregnant travellers in Thailand
Zika virus transmission
Zika virus circulates actively in Thailand, and there are regular documented cases of travellers acquiring congenital Zika syndrome after visiting the country, including cases reported from Phuket in 2024. Use DEET-based repellent of at least 20% concentration on all exposed skin, wear long sleeves at dawn and dusk, and stay in air-conditioned or well-screened accommodation throughout your trip.[1]
Dengue fever in pregnancy
Dengue is endemic throughout Thailand, with peak transmission during the rainy season (approximately May to October), though cases occur year-round. Dengue in pregnancy can cause premature birth and low birth weight; if you develop high fever, severe headache, or a rash during or after your trip, attend an emergency department immediately and tell clinicians you have been in Thailand.[2]
No public healthcare access for most international travellers
Thailand has no reciprocal public healthcare agreements with most countries, so all obstetric care at private hospitals is charged directly to you or your insurer. Private hospital delivery packages in Bangkok start at around ฿99,000 (~$3,030 / ~€2,590) and emergency neonatal intensive care adds significant additional cost. Comprehensive travel insurance with maternity and obstetric emergency cover is essential before departure.
Extreme heat and dehydration risk
Bangkok's heat index peaks at around 53°C on an average April afternoon and the tap water is not safe to drink. Limit environmental heat exposure to the management section of this guide.
Malaria in border regions
Malaria is endemic in rural forested areas near the borders with Myanmar, Cambodia, and Malaysia; Bangkok, Chiang Mai city, and Phuket carry minimal transmission risk. If your itinerary includes border provinces, discuss safe antimalarial options for pregnancy with your specialist before departure, as some antimalarials are contraindicated.[3]
Food and waterborne infection risk
Tap water is unsafe to drink throughout Thailand; use sealed bottled water for drinking and brushing teeth. Listeria and salmonella risks from street food are elevated in high heat; opt for freshly cooked hot food and peel all fruit yourself.
Preparation checklist
- Get a formal fit-to-fly assessment — Ask your obstetrician to confirm you are fit to travel, note any gestational age restrictions your airline applies, and obtain a written letter confirming your due date and absence of complications.
- Confirm your gestational age against airline rules — Most carriers restrict travel after 28 weeks on long-haul routes and 36 weeks on short-haul; check your specific airline's policy and carry written confirmation of your due date.
- Book a travel clinic appointment — Discuss Zika risk, safe mosquito repellent options, malaria prophylaxis if visiting border regions, and any vaccines that are contraindicated or recommended in pregnancy.
- Obtain insurance with explicit obstetric emergency cover — Confirm pregnancy complications, emergency delivery, and neonatal cover are named on the policy schedule before departure.
- Pack a 30-day supply of all medications in original labelled packaging — Thailand's Drugs Act permits a personal supply of up to 30 days; carry a doctor's letter listing each medication by INN and brand name.
- Identify your nearest private hospital with an obstetrics department — Research Bumrungrad International, Samitivej, or Bangkok Hospital before departure and save the address, phone number, and emergency line offline in Nomedic.
- Pack insect protection — Bring DEET-based repellent of at least 20% concentration, long-sleeved clothing for dawn and dusk, and a portable mosquito net if staying in less-screened accommodation.
- Store your IPS in Nomedic — Your International Patient Summary should list your gestational age, blood type, current medications, allergies, any high-risk classification, and your home specialist's contact details; share it at every appointment.
- Pack safe hydration supplies — Bring electrolyte sachets for use with sealed bottled water; tap water is unsafe throughout Thailand.
- Find a specialist — Search for obstetricians and maternal-fetal medicine specialists at your destination using the Nomedic provider directory before you travel.
Documents to carry
Documents to carry when travelling to Thailand during pregnancy
Carry all documents digitally on your phone using the Nomedic app and keep physical copies in your hand luggage. Thai clinicians at international private hospitals are accustomed to treating international patients and will expect to see documented clinical history on arrival.
Your International Patient Summary (IPS)
Your Nomedic IPS contains your gestational age, blood type, current medications with INNs, allergies, any high-risk pregnancy classification, and your home specialist's contact details in a format any clinician worldwide can read.
At Thai private hospitals, showing your IPS immediately at triage removes the need to reconstruct your obstetric history verbally and reduces the risk of missed information during language-barrier consultations. The QR code works offline.
Full document checklist
Keep the following accessible on your phone and ready to share. Your Nomedic IPS covers items 1 and 6 automatically.
- ·Your Nomedic IPS Gestational age, blood type, medications, allergies, high-risk classification, and home specialist contact. Offline and QR-accessible.
- ·Obstetrician's letter Must state gestational age, expected due date, any high-risk classification, current medications, and a statement that you are fit to travel.[5]
- ·
- ·Most recent antenatal scan and blood results Thai obstetricians will want to see your most recent ultrasound and lab work to continue your care without repeating tests unnecessarily.[6]
- ·Travel insurance schedule Policy number and insurer's 24-hour line saved in your Nomedic profile; confirm obstetric emergency cover is named.[8]
- ·Thailand emergency numbers Ambulance: 1669. Police: 191.[10] Fire: 199. Save these offline in Nomedic before you lose mobile data.
Medications advice
Bringing your medications to Thailand[4]
Under section 13(4) of Thailand's Drugs Act B.E. 2510 (1967), travellers may import a personal supply of any modern drug for up to 30 days in its original labelled container, accompanied by a valid prescription. For controlled psychotropic substances (Schedule II, III, or IV), a 30-day supply with a valid medical certificate requires no advance permit; a supply of 31 to 90 days requires a Form IC-2 permit from the Thai FDA obtained at least 15 days before travel. Postal import of medication is not permitted, all medications must be carried in person.[4]
Do not post your medication to Thailand.
Mailing prescription medication to Thailand is prohibited regardless of classification. Packages may be seized by customs, and the sender can face legal consequences under Thai drug law. Always carry medications in person in your hand luggage.
Common pregnancy-related medications: brand names and Thailand availability
Common pregnancy-related medications are available at private hospital pharmacies in Bangkok and major tourist areas; verify availability of your specific brand with the Thai FDA's Health Products Search tool before departure.
Widely available OTC at Thai pharmacies. No import permit required.
Available OTC. Keep in original packaging with prescription.
Requires prescription in Thailand. Storage varies by formulation: oral capsules (Utrogestan) and vaginal gel (Crinone) at room temperature; injectable forms (e.g. Susten) require refrigeration.
Available on prescription at private hospital pharmacies. Bring a 30-day supply; Thai formulations may differ in strength.
Cold-chain required (2–8°C). Carry in a medical cool pack. Available at major private hospital pharmacies; not routinely stocked at retail pharmacies.
Available OTC. Ensure dose is as prescribed; do not substitute with standard-strength aspirin products.
Caution: ibuprofen and aspirin at standard doses during pregnancy
Standard-dose ibuprofen (NSAIDs) and high-dose aspirin are contraindicated during pregnancy and are available over the counter at Thai pharmacies. If you present with fever from dengue or another infection, do not use ibuprofen. Paracetamol (acetaminophen) is the recommended antipyretic; confirm the brand name with the pharmacist, locally sold as Panadol or Sara.
Travelling with cold-chain medications
If you take progesterone, enoxaparin, or any other refrigerated medication, these steps apply regardless of your destination within Thailand.

At your destination
Healthcare and prescriptions in Thailand
Thailand operates a Universal Coverage Scheme (UCS, known locally as the Gold Card scheme บัตรทอง, bat thong) for Thai citizens, with a separate Social Security scheme (ประกันสังคม) for formal-sector employees; most international travellers cannot access either system. All obstetric care for travellers is accessed at private hospitals and billed directly. A single prenatal consultation at a private clinic costs approximately ฿800 to ฿3,000 (~$24 to $92 / ~€21 to €79); full delivery packages at Bangkok private hospitals start at ฿99,000 (~$3,030 / ~€2,590) for natural birth[5].
Foreign prescriptions are not directly transferable at Thai pharmacies; a Thai-licensed physician must issue a local prescription for you to receive medication from a Thai pharmacy. At private hospitals, the on-site pharmacy will fill prescriptions issued by the hospital's own obstetricians. Some medications commonly available over the counter elsewhere require a prescription in Thailand; confirm your specific items with the hospital pharmacist on arrival.
Cold-chain medications are dispensed through private hospital pharmacies
Refrigerated medications such as enoxaparin and progesterone are not routinely stocked at retail pharmacies outside major cities. For an emergency supply, go directly to the pharmacy of a private hospital with a maternity department, bring your IPS and prescribing doctor's letter, and ask the on-site obstetrician to issue a local prescription.
Finding an obstetrician in Thailand
Obstetricians and maternal-fetal medicine (MFM) specialists (สูตินรีแพทย์, sut-ni-rae-phaet) practice within the Women's Health Centres of major private hospitals including Bumrungrad International, Samitivej Sukhumvit, Bangkok Hospital, and BNH Hospital in Bangkok; Bangkok Hospital Phuket and Chiang Mai have dedicated MFM-led departments. These hospitals accept walk-in obstetric appointments, though booking in advance is recommended as high-risk pregnancy slots fill quickly. English-speaking staff are available at all named hospitals.[6]
Search for providers near your destination
Use Nomedic's provider search to find obstetricians and maternal-fetal medicine specialists in Thailand. Save the address and phone number offline before you travel.
If your cold chain breaks or medication runs out in Thailand
A brief temperature excursion does not automatically render a refrigerated medication unsafe. Check the specific product's SmPC (patient information leaflet) for the stated room-temperature tolerance window before discarding anything.
Managing heat, mosquitoes, and food safety day to day[7]
Bangkok's heat index peaks at around 53°C on typical April afternoons, and in 2024 Thailand's Department of Disease Control recorded 63 heatstroke deaths, with the majority occurring in April. Pregnancy compounds the risk of heat exhaustion, as blood volume is already expanded and thermoregulation is altered.[7]
Schedule outdoor activity before 10:00 or after 17:00. Bangkok has 255 designated cooling centres in schools, health centres, and district offices; BTS and MRT stations and 7-Eleven outlets also provide reliable air-conditioned relief. Drink only sealed bottled water and use it for brushing teeth. Apply DEET-based repellent of at least 20% concentration every four hours and sleep in air-conditioned or fully screened rooms to reduce dengue and Zika exposure. If you develop fever, rash, or joint pain, attend a private hospital emergency department the same day and inform clinicians of mosquito exposure.
Fever in pregnancy requires same-day assessment, not self-management
Dengue fever in the third trimester carries elevated risk of premature labour and perinatal complications. If you develop a temperature above 38°C with headache, eye pain, or rash, do not take ibuprofen, use paracetamol (Panadol) only and attend an emergency department immediately. If symptoms resolve within 24 hours of rest and hydration, you may have had a mild viral episode; if fever persists or fetal movement changes, follow the guidance in the Emergency tab.
Thai phrases for clinicians
Show your Nomedic IPS first, it removes the need to explain your diagnosis verbally. If verbal communication is needed:
“ฉันตั้งครรภ์อยู่”
I am pregnant.
“ฉันมีภาวะแทรกซ้อนในการตั้งครรภ์”
I have a pregnancy complication.
“ฉันต้องการพบสูตินรีแพทย์”
I need to see an obstetrician.
“ฉันกินยา [ชื่อยา] อยู่ระหว่างตั้งครรภ์”
I take [medication name] during my pregnancy.
“ห้องคลอดฉุกเฉินอยู่ที่ไหน”
Where is the emergency obstetric unit?
“ฉันต้องการยา [ชื่อยา] โดยด่วน”
I need an emergency supply of [medication name].
Insurance considerations
What to know about travel insurance
Thailand has no public health access for most international travellers, and private hospital obstetric packages start at ฿99,000 (~$3,030 / ~€2,590). Emergency complications, neonatal intensive care, or medical evacuation can cost many multiples of that, making comprehensive cover with explicit obstetric and emergency delivery clauses non-negotiable.
What to look for in a policy
Not just 'pre-existing conditions covered'. Emergency delivery, preterm labour, and obstetric haemorrhage should be listed on the schedule.
Covers medical repatriation if local obstetric or neonatal care is insufficient for your situation.
Neonatal ICU at Bumrungrad International Hospital costs ฿4,400 to ฿17,800 per day; confirm your policy covers the newborn from birth.
So your insurer can communicate directly with Thai-speaking clinicians on your behalf.
What to declare at application
Declare thoroughly. Incomplete disclosure can invalidate your entire policy, not just the pregnancy-related claim.
Insurers apply different cutoffs, typically 28 weeks or 32 weeks, after which obstetric cover is excluded or requires a fit-to-fly certificate.
Use the INN alongside the brand name for each item.
Include gestational diabetes, hypertension, placenta praevia, multiple pregnancy, or any MFM referral.
Pre-existing conditions such as autoimmune disease, thrombophilia, or cardiac conditions that are being managed alongside the pregnancy.
Your policy number and emergency assistance line, saved alongside your IPS and accessible offline.
Thailand is outside the EU and EEA, so EHIC and GHIC cards provide no coverage here. EU and EEA passport holders travelling to Thailand require a private travel insurance policy with explicit obstetric and emergency delivery cover, regardless of EHIC entitlement elsewhere.
Emergency protocol
Get to a private hospital emergency department immediately
A pregnancy emergency, including heavy bleeding, severe abdominal pain, reduced fetal movement, signs of preeclampsia (severe headache, visual disturbance, sudden oedema), or fever above 38°C, requires immediate emergency assessment, not a call to your travel insurer first. Call 1669 for an ambulance or go directly to the nearest private hospital emergency department. Contact your insurer's 24-hour line as soon as you are safely inside the hospital.
When you arrive, follow in order
Full clinical picture in seconds, gestational age, blood type, medications, allergies, and home specialist contact.
Hand your phone to the triage nurse:
ฉันตั้งครรภ์และมีอาการฉุกเฉิน ต้องการพบแพทย์ทันที
I am pregnant and have an emergency. I need a doctor immediately.
Tell the triage team your gestational age in weeks and whether you have any high-risk classification (e.g., placenta praevia, pre-eclampsia, twins).
If offered pain relief or antipyretics, confirm with the clinician that paracetamol is being used, not ibuprofen or aspirin at standard doses.
Calls and location
Ambulance: 1669. Police: 191. Fire: 199. If you cannot describe your location in Thai, use Google Maps to share your GPS coordinates with the operator or ask hotel staff to call on your behalf.
In hospital
Even a minor fall or impact to the abdomen during pregnancy can cause placental abruption or fetal distress without obvious external injury. Tell the emergency team you are pregnant, state your gestational age, and request a fetal heart rate assessment and ultrasound before any imaging involving radiation.
After any emergency
Before you leave the hospital if possible.
Required for insurer reimbursement and for your home obstetrician to continue your care.

Frequently asked questions
Can I bring my pregnancy medications into Thailand?
Under Thailand's Drugs Act B.E. 2510 (1967), travellers may bring a 30-day personal supply of any modern drug in its original labelled container with a valid prescription; controlled psychotropic substances at 31 to 90 days require a Form IC-2 permit from the Thai FDA obtained at least 15 days before travel.[4]
Do not post medication to Thailand
Postal import of prescription medication is prohibited. Always carry medications in person in your hand luggage.
Are pregnancy medications available at Thai pharmacies?
Basic supplements such as folic acid and iron are available over the counter at Thai retail pharmacies. Cold-chain medications such as enoxaparin and progesterone are stocked at private hospital pharmacies in Bangkok and major cities, not at typical retail outlets. A Thai-licensed physician must issue a local prescription before any pharmacy can dispense a controlled or prescription-only medication.

How can I communicate my pregnancy situation in an emergency in Thailand?
Show your Nomedic IPS first, it displays your gestational age, blood type, medications, and allergies in a format Thai clinicians can read immediately. If verbal communication is needed:
“ฉันตั้งครรภ์และมีอาการฉุกเฉิน ต้องการพบแพทย์ทันที”
I am pregnant and have an emergency. I need a doctor immediately.
“ฉันกินยา [ชื่อยา] อยู่ระหว่างตั้งครรภ์”
I take [medication name] during my pregnancy.
Is Zika virus a real risk for pregnant travellers in Thailand?
Yes. Zika virus is endemic in Thailand and there are regular documented cases of travellers acquiring congenital Zika syndrome (CZS) after visits, including a confirmed case of severe microcephaly following a trip to Phuket in 2024. The CDC recommends that pregnant travellers review current guidance before visiting, as there is no treatment or vaccine for Zika.[1]
Mosquito protection is your primary defence
Use DEET repellent of at least 20% concentration every four hours on all exposed skin. Sleep in air-conditioned or fully screened rooms. Zika-transmitting Aedes mosquitoes bite during the day, not only at dusk.
Do I need special travel insurance to visit Thailand while pregnant?
Standard travel policies commonly exclude pregnancy-related claims; you need a policy that explicitly names obstetric emergencies, emergency delivery, and neonatal cover on its schedule. Private hospital delivery packages in Thailand start at ฿99,000 (~$3,030 / ~€2,590), and neonatal ICU at major Bangkok hospitals costs ฿4,400 to ฿17,800 (~$135 to $545 / ~€115 to €466) per day, making comprehensive cover essential.
Declare thoroughly
Gestational age, expected due date, any high-risk classification, current medications, and associated pre-existing conditions. Incomplete disclosure can invalidate the entire policy, not just the pregnancy-related claim.
