Tonsillitis in Children: Signs, Causes, and Treatment

February 2, 2026

Tonsillitis is a common issue that affects children. The symptoms are very similar to a common cold, thus making it difficult to identify until the symptoms are severe or the child is in a lot of discomfort. Is tonsillitis very different from a regular sore throat? What are the signs, causes and treatment for this condition? Read on to know all about it.

What is Tonsillitis?

Tonsils are the two tissue masses at the back of your throat. These tissue masses are the filters that trap germs and protect your airways from infection. An infection of these tonsils is known as tonsillitis. It causes the tonsils to swell in size and become red and sore. Tonsillitis is common among children aged 5 to 15. As the tonsils reduce in size after puberty, tonsillitis in adults is quite rare. 

Types of Tonsillitis

Tonsillitis can be classified into three types – 

  1. Acute Tonsillitis – It is the most common type of tonsillitis to affect children. The symptoms occur suddenly and can persist for a few days. Often caused by viral or bacterial infection, this type of tonsillitis can last anywhere between 3-4 days or even up to 2 weeks. It causes inflammation of the tonsils, making it difficult to swallow. 
  2. Recurrent Tonsillitis – When acute tonsillitis recurs multiple times within a short period, it is known as recurrent tonsillitis. Suppose a child has 7 or more episodes of acute tonsillitis within a span of one year or 5 or more episodes per year for 2 consecutive years, or 3 or more episodes per year for 3 years in a row. In that case, it is diagnosed as a recurrent tonsillitis. 
  3. Chronic Tonsillitis – When the inflammation of the tonsils lasts for months, it is known as chronic tonsillitis. The symptoms are milder compared to acute tonsillitis, but they are more persistent. The sore throat, swollen tonsils, pain while swallowing, and even bad breath can last for months. When tonsillitis is not treated properly, it can become chronic. 

What Causes Tonsillitis?

As mentioned earlier, tonsillitis is the inflammation of the tonsils. Inflammation in the body happens when that body part is attacked, and it starts fighting the infection to protect itself. Tonsillitis in children can be caused by bacterial or viral infection. 

Bacterial Tonsillitis

Bacterial tonsillitis is mostly caused by the Group A Streptococcus bacteria, which also causes strep throat. It is very contagious and can be transferred easily through close contact or through respiratory droplets that are released when coughing or sneezing. In rare cases, bacterial tonsillitis can lead to quinsy – a complication where an abscess forms near the tonsil, thus pushing it to the centre of the throat, making it very painful and difficult to breathe freely.

Viral Tonsillitis

Viral tonsillitis is caused by various viruses and is less severe than bacterial tonsillitis. Viruses such as adenoviruses, influenza viruses, Epstein-Barr virus, Parainfluenza viruses, Enteroviruses, Herpes simplex virus, and HIV can cause inflammation of the tonsils, leading to tonsillitis.

Treating Tonsillitis in Children

So, how do you treat your child’s tonsillitis? Can you prevent it from recurring?

  • Home Remedies - Viral tonsillitis does not require any antibiotics. It can be treated with simple home remedies like hydration, plenty of rest, and drinking warm liquids to soothe the throat. Gargling with salt water is a very common home remedy for both tonsillitis and sore throat, as the salt can help fight the germs causing the inflammation. 
  • Humidifier - In case the atmosphere around you is too dry and is irritating the child’s throat, you can try using a humidifier in the room. The humidifier can help add moisture to the room atmosphere and, in turn, help with the sore throat.
  • Pain Killers - If your child’s discomfort or pain is too severe, the doctor might prescribe some child-safe over-the-counter pain relief medications. Never give your child such medications unless prescribed by a qualified doctor. 
  • Others - While throat lozenges are readily available for throat irritation, they are not safe for young children. Never give them to your child unless the doctor prescribes them. 
  • Antibiotics - Bacterial tonsillitis requires antibiotics like penicillin or amoxicillin. If your doctor prescribes these medications, ensure your child completes the prescribed course; it may lead to complications or recurrent infections. 
  • Tonsillectomy - If the infection is severe or recurrent in nature, the doctor might recommend removing the tonsils. 

Conclusion

Tonsillitis is quite common among children of school-going age. The proximity to other infected children and the weak immune systems increase the risk for children between 5 and 15 years of age. If symptoms persist, it is always advisable to get checked rather than ignore them as just a sore throat.

Frequently Asked Questions

What are the main signs and symptoms of tonsillitis in children?

The most common signs and symptoms of tonsillitis in kids are a scratchy throat, sore throat, and pain or discomfort while swallowing. Closer inspection of the tonsils can reveal red or swollen tonsils, possibly with white or yellow spots on them.

How is tonsillitis diagnosed in children?

Sore throat and other cold-related symptoms are regularly seen in young children. If they experience a sore throat, pain when swallowing, and swollen or red tonsils, it indicates an issue with the tonsils. The doctor will take a swab test to determine if it is a viral or bacterial tonsillitis and recommend treatment accordingly.

When should I take my child to the doctor for tonsillitis?

If your child presents the classic symptoms of tonsillitis, like a sore or scratchy throat, inflamed and red tonsils, spots on the tonsils, or difficulty in swallowing, you should consult a doctor immediately. Viral tonsillitis can go away on its own, but bacterial tonsillitis can worsen quickly and requires antibiotics for a full recovery.

When is surgery (tonsillectomy) required for tonsillitis in children?

Recurrent tonsillitis, persistent or worsening symptoms, causing too much pain for the child, requires a tonsillectomy - a surgery to remove the infected tonsils. Recurrent episodes of tonsillitis along with pus formation, fever, or swollen lymph nodes can cause breathing problems and other complications. Removing the infected tonsil is the only viable option.
