COVID-19 Treatment in Phuket: Testing, Antivirals and Travel Advice
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician, Takecare Clinic Phuket. Last reviewed: September 2026.
“Most people who come to us with COVID-19 now are not seriously ill. What worries them is the practical side: whether they can still fly home on Saturday, whether their elderly parent on the same trip needs medicine, and what their insurer will want to see. Those are the questions a good consultation should answer, alongside checking that the lungs are fine.” Dr. Ponlawat Pitsuwan
COVID-19 today: what it is and who is at risk
COVID-19 is an infection caused by the SARS-CoV-2 coronavirus. It spreads mainly through the air when an infected person breathes, talks or coughs, especially indoors. Symptoms usually start two to five days after exposure. Years of vaccination and previous infection mean most people now have a mild illness similar to a cold or flu, but it can still cause pneumonia and serious illness in some groups.
The people most likely to become seriously unwell are adults over 60 to 65, and people of any age with conditions such as diabetes, heart or lung disease, chronic kidney disease, obesity, cancer or a weakened immune system, as well as those who are unvaccinated or pregnant. Identifying whether you fall into one of these groups is the most important part of a COVID-19 consultation, because it decides whether antiviral treatment is worthwhile.
Symptoms, and how COVID-19 compares with look-alikes
Common symptoms are a sore or scratchy throat, blocked or runny nose, cough, fever, tiredness, headache and muscle aches. Loss of smell or taste is less common than earlier in the pandemic. Many patients describe it simply as “a bad cold”. Because influenza and dengue are both common in Phuket, a positive home test is helpful, but fever with severe body aches and no cough should also prompt a dengue check. Our flu treatment in Phuket page explains how we tell flu apart, since the two viruses often circulate together in the rainy season.
Testing for COVID-19 in Phuket
An antigen test kit (ATK), the rapid lateral flow test sold in Thai pharmacies and 7-Eleven stores, is accurate enough for diagnosis when you have symptoms. It is most reliable from day two or three of symptoms, so a negative result on day one should be repeated 24 to 48 hours later if you still feel ill. At the clinic we perform a professional rapid antigen test and, where it makes sense, a combined swab for influenza.
A PCR test, which detects the virus’s genetic material, is more sensitive but is rarely needed for treatment decisions now. Some travellers still need one because an employer, cruise line or destination asks for it. If that applies to you, tell us when you message us, and we will advise on the right test and paperwork.
| Your situation | Usual approach | Where to be seen |
|---|---|---|
| Healthy adult under 60, mild symptoms | Rest, fluids, paracetamol, throat lozenges; antivirals usually not needed | Home care; clinic if not improving after 5 days |
| Over 60, or with a risk condition, within 5 days of symptoms | Doctor review for nirmatrelvir with ritonavir, after checking medicines and kidney function | Clinic or hotel visit the same day |
| Fever above 39°C, persistent cough, oxygen level borderline | Chest examination, pulse oximetry, consider chest X-ray | Clinic today |
| Breathless at rest, chest pain, confusion, blue lips | Oxygen and hospital treatment | Emergency department or call 1669 |
How we treat COVID-19 at Takecare
The doctor confirms the diagnosis, asks when your symptoms began, reviews your medical history and every medicine you take, and examines your throat and chest. We measure your oxygen saturation with a pulse oximeter, a clip on the finger that shows how well your lungs are delivering oxygen. A normal reading at rest is 95% or higher.
For higher-risk adults seen within five days of symptom onset, international guidance from the WHO and CDC recommends nirmatrelvir combined with ritonavir, taken twice a day for five days. It lowers the risk of hospital admission in people who are most vulnerable. Ritonavir interacts with many common medicines, including some statins, blood thinners, heart rhythm drugs and sedatives, so bring your tablets or a list, and we may adjust or pause other medicines during the course. The dose is reduced for people with moderate kidney disease. Some patients notice a metallic taste. Where it is unsuitable, the doctor will discuss alternatives available in Thailand.
For everyone else, treatment focuses on symptoms: paracetamol for fever and aches, lozenges or warm drinks for the throat, and rest. Antibiotics do not act on the virus. If your throat is the worst part, our sore throat treatment page describes what helps most. Recovery usually takes about a week for most healthy adults, although tiredness and a cough can linger for several weeks; symptoms that last beyond 12 weeks deserve a review with your own doctor.
Isolation and flying after COVID-19
Thailand ended mandatory isolation in 2022 and now manages COVID-19 as a communicable disease under surveillance, so the rules are advice rather than law for most visitors. We advise staying in your room while you have a fever or feel unwell, and wearing a well-fitting mask around others for about five days after a positive test, especially near older people. Your hotel or tour operator may have its own policy. Check with them, and we can document your diagnosis if they need it.
Long-haul flights add three considerations. Cabin air pressure is lower than at sea level, so if your oxygen level is borderline, a long flight can make breathlessness worse. Sitting still for many hours raises the risk of blood clots in the legs, which infection increases further, so walk the aisle and keep hydrated. And airlines can refuse to board passengers who look acutely unwell. If you are due to fly within a few days of a positive test, a fit-to-fly certificate from our doctor, after a check of your chest and oxygen level, can make the journey smoother.
When to see a doctor
See a doctor within a day or two of a positive test if you are over 60, pregnant, or have any long-term health condition, because the antiviral window closes at five days. Also come in if your fever lasts more than three to four days, if you start to improve and then get worse, or if a cough becomes productive with discoloured phlegm. People with asthma who notice more wheeze should be seen early.
Go directly to a hospital emergency department or call 1669 if you are breathless at rest or while talking, have chest pain or pressure, blue or grey lips, confusion, a new inability to stay awake, or an oxygen reading below 94% on a home oximeter.
Prevention and early detection
Staying up to date with a COVID-19 vaccine remains the best protection against severe illness, particularly for people over 65 and those with chronic conditions. Check your home country’s booster advice before you travel. On the trip itself, a mask in crowded airports and on flights reduces your risk, and good ventilation matters more than surface cleaning.
Early detection is what makes treatment possible for vulnerable travellers. Pack a few antigen tests, or buy them locally, and test as soon as symptoms start rather than waiting. If you are travelling with an older relative, agree in advance that they will test and contact a doctor on the first day of symptoms.
Visiting Takecare Clinic in Phuket
We are open 24 hours a day at our Bangtao (Cherngtalay) branch, Takecare Clinic Kata-Karon and the Patong clinic. Please message us before arriving if you have tested positive, so we can see you in a way that protects other patients. Most visits take under 30 minutes.
Many people with COVID-19 prefer not to travel at all. A hotel room visit from a doctor lets us test, examine and treat you where you are staying. You can reach us on WhatsApp at +66 95 073 5550 or by phone on 081-718-9080.
We confirm the price before your visit, provide direct billing with most travel insurers, and give you a medical report and itemised receipt for any claim or for your airline.
Related services and treatments
COVID-19 can leave a cough that lasts for weeks. If it becomes chesty, our bronchitis care page explains what to expect, and people with asthma should see our asthma treatment in Phuket page, since viral infections are a leading cause of flare-ups. Severe throat pain with white patches may be tonsillitis needing treatment rather than COVID-19 itself.
A blocked nose from COVID-19 can cause ear pain on the flight home, which our ear infection treatment page covers. Sneezing and itching without fever are more likely to need allergy treatment. For any other health issue, a walk-in doctor in Phuket can see you at any branch.
Summary
COVID-19 is now mild for most travellers, and a professional antigen test confirms it quickly. The key decision is whether you are at higher risk, because nirmatrelvir with ritonavir, started within five days, reduces serious illness in that group. Everyone else needs symptom care and sensible distancing from vulnerable people. Breathlessness, chest pain or low oxygen levels mean hospital care, and a doctor’s check before a long flight is worthwhile if you tested positive recently.
“Test early, and if you or someone you are travelling with is older or has a chronic condition, contact us on the first day of symptoms rather than the fifth. Bring every tablet you take, because checking interactions is what makes the antiviral safe.” Dr. Ponlawat Pitsuwan
Frequently asked questions
Do I have to isolate if I have COVID-19 in Thailand?
Thailand no longer has legally mandatory isolation for most people with COVID-19. Current advice is to stay away from others while you have a fever or feel unwell, and to wear a mask around other people for about five days after a positive test. Hotels, tours and employers may have their own rules. We can advise at your visit and provide documentation if you need it.
Who should take Paxlovid for COVID-19?
Paxlovid, the brand name for nirmatrelvir with ritonavir, is recommended for adults at higher risk of severe illness, such as those over 60 or with diabetes, heart, lung, kidney or immune conditions, when started within five days of symptoms. It interacts with many medicines, so a doctor must review everything you take before prescribing it. Healthy younger adults rarely need it.
Can a doctor come to my hotel to treat COVID-19?
Yes. Our doctors visit hotels and villas across Phuket 24 hours a day. The doctor can perform the test, examine your chest, check your oxygen level and start treatment in your room. This is often the best option if you have tested positive, because it avoids taxis and waiting rooms and protects other people.
Can I fly home with COVID-19?
Most airlines no longer require a negative test, but they can refuse passengers who appear unwell, and a long flight with low oxygen levels or a high fever can be risky. Ideally, fly when your fever has settled and you feel well enough to travel. If you need to fly sooner, a doctor’s assessment and fit-to-fly letter is sensible. Check your airline’s rules.
Will travel insurance cover COVID-19 treatment in Phuket?
Many travel insurance policies now cover COVID-19 like any other illness, but some have specific exclusions, so check your policy wording. We offer direct billing with most travel insurers and provide a medical report, test result and itemised receipt for claims. Message your insurer’s name on WhatsApp and we will check before your visit.
How long will COVID-19 symptoms last?
Most people feel clearly better within a week, although tiredness and a cough can linger for two to three weeks. A small number develop longer-lasting symptoms, known as long COVID, that persist beyond twelve weeks. If you are getting worse rather than better after five days, or breathlessness develops, see a doctor rather than waiting it out.
