A sudden severe sore throat with fever is one of the most common reasons travellers walk into our clinic in Patong. Most sore throats are viral and settle on their own, but around one in ten adults and three in ten children with sore throat have true strep, which does benefit from antibiotics. A two-minute throat swab tells us which group you are in, so we treat only when treatment is genuinely needed.
What strep throat is and how we test for it
Strep throat, or streptococcal pharyngitis, is caused by Group A Streptococcus, a bacterium that spreads in respiratory droplets and on shared cutlery, glasses and surfaces. It is distinct from the viral pharyngitis that causes seventy to eighty percent of sore throats, where antibiotics do not help. To decide who needs testing, we use the Centor and McIsaac criteria, scoring one point each for tonsillar exudate (white patches), tender swollen glands at the front of the neck, a history of fever above 38 degrees Celsius, and the absence of cough. Age adjusts the score: under fourteen adds a point, forty-five and over subtracts one. Three or more points justifies a rapid antigen detection test, which gives a result in five to ten minutes with around eighty-five percent sensitivity and ninety-five percent specificity. A positive test confirms strep; a negative result, combined with the clinical picture, points strongly to a viral cause.
Antibiotic treatment we provide
First-line treatment, following CDC, NICE and NHS guidance, is penicillin V 500 mg four times daily for ten days. Amoxicillin 500 mg three times daily for seven to ten days is equally effective and easier for children to take. For patients with a penicillin allergy, we use azithromycin 500 mg on day one followed by 250 mg daily on days two to five, or cephalexin 500 mg twice daily for ten days when the allergy is mild. Symptoms usually improve within twenty-four to forty-eight hours of starting antibiotics, and you are considered non-infectious after a full day of treatment. We always pair antibiotics with paracetamol or ibuprofen for pain and fever, salt-water gargles, throat lozenges and plenty of cool fluids. If a rash develops on amoxicillin, particularly in a teenager or young adult, we reconsider the diagnosis because this can indicate undiagnosed glandular fever (Epstein-Barr virus) rather than true allergy.
Centor score and differential diagnosis
| Feature or condition | Clinical clues | What we do |
|---|---|---|
| Centor 0 to 1 | Cough, runny nose, mild sore throat, no fever. | Likely viral. Symptomatic care, no swab, no antibiotics. |
| Centor 2 | Fever or exudate or tender glands, but not all. | Clinical judgement. Often swab if symptoms severe. |
| Centor 3 to 4 | Exudate, tender adenopathy, fever, no cough. | Rapid antigen test. Treat if positive. |
| Glandular fever (EBV) | Prolonged fatigue, large glands, splenomegaly, teenagers. | Monospot or EBV serology. Avoid amoxicillin (rash). |
| Peritonsillar abscess | One-sided swelling, trismus, muffled “hot-potato” voice. | Urgent referral, drainage and IV antibiotics. |
| Epiglottitis | Drooling, stridor, sitting forward, very unwell. | Airway emergency. Do not examine the throat. Hospital. |
When to see a doctor
A sore throat lasting more than three to five days, or any sore throat with high fever, very swollen glands, white patches on the tonsils, difficulty swallowing your own saliva or a rash, deserves a clinical assessment. The reason we worry is not the throat itself but the rare complications of untreated strep: acute rheumatic fever (which can damage heart valves), post-streptococcal glomerulonephritis (kidney inflammation that can present a week or two later with dark urine), peritonsillar abscess and scarlet fever.
You cannot swallow your saliva and are drooling. You hear noisy breathing or stridor. You can only open your mouth a small amount (trismus). You have a one-sided neck or throat swelling with a muffled voice. Fever stays above 38.5 degrees Celsius for more than five days despite antibiotics. You develop dark cola-coloured urine or facial swelling one to two weeks after a sore throat. These can mean peritonsillar abscess, epiglottitis or post-streptococcal kidney disease, all of which need urgent care.
Your sore throat is severe, you have a fever, your glands are tender, or you simply want to know whether you need antibiotics before flying home. A fifteen-minute visit with a rapid antigen swab settles it. WhatsApp +66 95 073 5550 for a same-day clinic appointment or hotel visit, day or night.
Prevention and early self-care
Group A Streptococcus spreads through respiratory droplets from coughing, sneezing and talking at close range, and through shared drinks, cutlery and toothbrushes. The most effective prevention is straightforward: wash hands with soap and water for twenty seconds, cover coughs and sneezes with a tissue or elbow, avoid sharing glasses or utensils with anyone who has a sore throat, and replace your toothbrush after starting antibiotics. While you are recovering, rest the voice, drink cool fluids, gargle warm salt water several times a day, and use paracetamol or ibuprofen for pain. Stay home from work, the gym or the dive boat for at least twenty-four hours after the first antibiotic dose, since you remain infectious until then.
Summary
Most sore throats are viral and do not need antibiotics, but a minority are true Group A streptococcal infection that benefits from a ten-day course of penicillin or amoxicillin. A five-minute rapid antigen swab at our Patong clinic tells us which is which, and antibiotic treatment, when indicated, shortens symptoms by about a day and prevents rare but serious complications. If you have severe one-sided pain, drooling, stridor or symptoms returning weeks later with dark urine, that is a different conversation and we will see you the same day.
“The point of antibiotics in strep throat is not to make you feel better one day sooner. It is to prevent the small number of patients who would otherwise go on to rheumatic fever or kidney complications. That is why we test, and why we finish the course.”

Frequently asked questions
How do I know if my sore throat is strep or just a virus?
The classic strep picture is sudden severe sore throat with fever, white patches on the tonsils, tender swollen glands at the front of the neck and no cough or runny nose. Viral sore throat usually comes with cough, blocked nose and hoarseness. Only a rapid antigen swab gives a definite answer, and we keep these in stock at the clinic for same-visit testing.
How long does strep throat last with antibiotics?
Most patients feel significantly better within twenty-four to forty-eight hours of starting penicillin or amoxicillin. The full course is ten days for penicillin and amoxicillin, five days for azithromycin. Finish the full course even if you feel well, because stopping early raises the risk of relapse and of rheumatic complications.
Can the clinic come to my hotel for a strep test?
Yes. Our doctor and nurse can perform the rapid antigen swab, write a prescription and deliver the first dose at your hotel anywhere in Patong, Kalim, Kamala, Karon and Surin, day or night. WhatsApp +66 95 073 5550 to arrange a visit.
Is strep throat contagious, and when can I return to work or diving?
Strep is contagious through droplets and shared items. You are considered non-contagious after twenty-four hours on appropriate antibiotics and once your fever has settled. We usually advise resuming normal activity at forty-eight hours, and we ask divers to avoid the water for at least seventy-two hours because of ear and sinus pressure during recovery.
What if I am allergic to penicillin?
We prescribe azithromycin (a five-day course) or cephalexin where the penicillin allergy is mild and not anaphylactic. Tell us the exact nature of the previous reaction, because a childhood rash is often not a true allergy and broadens your options. If anaphylaxis or severe blistering has ever occurred, we avoid all beta-lactam antibiotics.
When is a sore throat a medical emergency?
Drooling, noisy breathing, inability to open the mouth more than a finger-width, severe one-sided swelling with a muffled voice, or a stiff neck with high fever are red flags for peritonsillar abscess or epiglottitis. These need hospital assessment, not a clinic visit. Call us first on +66 81 718 9080 and we will arrange transfer.
