Key facts
A sore throat, or pharyngitis, is when the throat is red, swollen and painful, especially when you swallow.
The most common cause of a sore throat is a virus, but some sore throats are caused by the bacteria streptococcus pyogenes — this is a ‘group A streptococcus’, sometimes called ‘strep A’.
There is no way to cure a sore throat that is caused by a virus.
If the sore throat is caused by bacteria, you may benefit from antibiotics.
Sometimes, when the sore throat is caused by strep A, complications can occur, including an abscess at the back of your throat, rheumatic fever and problems with your kidneys.

What is a sore throat?
A sore throat, or pharyngitis, is when your throat is red, swollen and painful, especially when you swallow. It happens when the back of the throat, called the pharynx, is inflamed.
Sore throats are very common in children.
What symptoms are related to a sore throat?
A sore throat is pain or a scratchy sensation in the throat which may worsen with swallowing or talking. It may be difficult to swallow. The throat might also be red, with white patches or streaks of pus. If the sore throat is caused by a cold virus, you may also have a runny nose, cough, possibly fever and feel very tired.
Children with a sore throat may eat less than usual.
If the sore throat is caused by an infection with streptococcal bacteria, (strep throat) other symptoms may include:
swollen lymph nodes (glands) in the neck
swollen red tonsils
rash
fever
abdominal (tummy) pain
vomiting
What causes a sore throat?
The most common cause of a sore throat is an infection from a virus, such as a cold or the flu, COVID-19 or glandular fever.
Less than 1 in 3 sore throats is caused by a bacterial infection. Some sore throats are caused by the bacteria streptococcus pyogenes (strep A). This is sometimes called ‘strep throat’. If your sore throat is caused by bacteria, you may feel very unwell.
Sometimes a sore throat can be caused by tonsillitis (inflammation of the tonsils), mouth ulcers or allergies.
How is the cause of a sore throat diagnosed?
If you or your child has a sore throat and you are worried about the symptoms, see your doctor.
The doctor will look at your throat with a torch and feel your neck for swollen glands. They may take a throat swab to try and find the cause of infection. Swabs can test for a range of viruses and bacteria.
When should I see my doctor?
Usually, sore throats go away without treatment in 2 to 7 days.
You should see your doctor if your child:
has a sore throat lasting longer than 2 days
is drinking poorly, longer than 1 day
has difficulty swallowing
is snoring more when they’re asleep
has large tender lumps in their neck
has a new skin rash, or bruising
has ear pain
When to seek urgent care
Seek immediate medical help if you or your child:
have trouble breathing, or have fast, noisy breathing
have a stiff or swollen neck (rather than throat pain)
have a rash that does not fade when the skin is pressed
are very drowsy
have cold or discoloured hands and/or feet, with a warm body
have pain in your arms and/or legs
your lips, or the skin around your lips, are an unusual colour (pale or blue)
CHECK YOUR SYMPTOMS — Use the Symptom Checker and find out if you need to seek medical help.
How is a sore throat treated?
There is no way to cure a sore throat caused by a virus. Most sore throats will get better without treatment in 2 to 7 days.
Self-care at home
These self-care remedies may help you feel better, such as:
rest
staying well hydrated by drinking plenty of water
drinking hot water with honey and lemon
gargling with warm salty water
eating soft foods like yoghurt, soup, ice cream, ice blocks or jelly
avoiding foods that cause pain when you swallow
If you have an existing medical condition, check with your doctor about how much water and fluid is right for you.
Smoking or breathing in other people’s smoke can make symptoms worse. Try to avoid being around people who are smoking. If you are a smoker, try to cut down or quit. For advice on quitting smoking, visit the Quit Now website.
Find out more about self-care tips on what to do if you have a high temperature (fever).
Medicines for a sore throat
Pain relief medicines can ease the symptoms of a sore throat.
Adults and children older than one month can take paracetamol, and adults and children older than 3 months can take ibuprofen. Do not give aspirin to children under 16 years.
If the sore throat is caused by bacteria, you may benefit from antibiotics.
The Australian Commission on Safety and Quality in Health Care has developed a guide which can be used with your doctor to help you decide whether to use antibiotics when you or your child has a sore throat.
Other over-the-counter medicines might help, such as lozenges or throat gargles that contain local anaesthetic. If you are pregnant or breastfeeding, it is best to avoid products that contain iodine. Your pharmacist can give you more information.
Can a sore throat be prevented?
Sore throats are very common and can’t always be prevented. You can help prevent sore throats by doing your best to stay healthy, including:
washing your hands well and often
covering your nose and mouth when sneezing or coughing
keeping people with strep throat, out of school, childcare and work until they have been taking antibiotics for 24 hours and feel well
not sharing eating utensils, food or drinks
throwing away used tissues appropriately
Complications of a sore throat
Most sore throats go away without treatment and don’t cause complications. Sometimes, when the sore throat is caused by strep A, complications can occur.
One complication is an abscess (a pocket of pus), which develops next to the tonsils or in the back of the throat.
Another complication is rheumatic fever. Rheumatic fever can develop after the sore throat has gone away. You may have fever, joint pain, rash, inflammation of the heart and other symptoms.
You may also develop problems with your kidney after having a strep infection.
