Infection of the throat by streptococcus bacteria can cause acute pharyngitis or strep throat. This usually causes sore and scratchy throat in children. Although strep throat may occur at any age, children are most vulnerable to this infection and its complications. Seek prompt medical care if your child has strep throat.

Read this post to know more about the causes, symptoms, risk factors, diagnosis, and treatment of strep throat in children and ways to prevent it.

Causes Of Strep Throat In Children

Strep throat is caused by group A streptococcus (GAS) bacteria, also known as Streptococcus pyogenes. It is a highly contagious disease that can easily spread from an infected person to others through respiratory droplets expelled while coughing or sneezing.

Direct spread may happen by sharing drinks, food, personal items, or by touching contaminated surfaces, such as doorknobs. Touching the nose, mouth, or eyes with unwashed hands after handling the contaminated surfaces can be a significant cause of infection in children (1). It may take two to five days of the incubation period to develop symptoms after strep bacteria reach the body.

Children with an active infection, rather than asymptomatic carriers, spread bacteria to others. Usually, strep infection is not contagious 24 hours after starting antibiotics or once the fever subsides.

Risks Factors For Strep Throat In Children

Children aged five to fifteen years are more likely to get strep throat. Children younger than three years rarely develop strep throat, and usually have a condition called mucopurulent rhinitis and fever called streptococcosis or streptococcal fever (2).

Although it may occur in any season, winter and early spring have a high incidence of strep throat infection. The bacteria tend to spread between groups of people in close contact, such as children at school or daycare (3).

Signs And Symptoms Of Strep Throat In Children

The following symptoms and signs are seen in children with strep throat (4).

  1. Sudden onset of throat pain
  2. Pain while swallowing
  3. Swollen tonsils
  4. Red tonsils with white patches or pus
  5. Small red spots in the palate (roof of the mouth)
  6. Tenderness and swelling of the lymph nodes in the neck
  7. Headache and body ache
  8. Skin rash
  9. Fever
  10. Nausea and Vomiting
  11. Poor appetite

These symptoms and signs are also seen in other causes of sore throat, such as viral infection. Tests may be required to identify the cause of sore throat and begin antibiotic therapy for strep throat.

When To See A Doctor

If your child has signs and symptoms of strep throat, seek prompt medical care. Timely diagnosis can help in differentiating strep throat from other causes of sore throat in children. It can also help avoid any potential complications of strep infection.

Complications Of Strep Throat In Children

Strep throat in children can be cured with appropriate treatment. However, untreated strep throat infection may spread to other parts of the body to cause the following complications (5).

  • Peritonsillar abscess
  • Mastoiditis

Timely treatment with antibiotics could decrease the risk of complications.

The antibodies produced against bacteria by the immune system may cross-react with the body’s tissues, resulting in the following inflammatory reactions (6) (7) (8).

  • Scarlet fever or scarlatina is caused by strep bacteria and causes high fever, bright red skin rashes, and sore throat in children.
  • Post-streptococcal glomerulonephritis (PSGN) is an inflammation of the kidneys that develops about ten days after the development of strep throat infection. Sudden onset of hematuria (red blood cells in urine) and proteinuria (protein in urine) are seen in this disease.
  • Post-streptococcal reactive arthritis is inflammation of the joints due to immune reaction.
  • Rheumatic fever is a severe complication that affects the heart, especially the heart valves. It can also cause tender joints and skin nodules.

Rarely, strep throat may lead to pediatric neuropsychiatric disorders, such as tic disorders and obsessive-compulsive disorders. This condition is called PANDAS (pediatric autoimmune neuropsychiatric disorder associated with streptococcus infections). However, the relation of strep throat and psychiatric disorders requires more studies (9).

Diagnosis Of Strep Throat In Children

The following tests are often used to diagnose strep throat after the physical examination (5).

  • A rapid antigen test is done on the throat swab, and this gives results in minutes.
  • Throat swab and tonsil secretions are collected for culture, the results of which are usually available in a couple of days.

Symptoms such as cough, rhinitis, voice changes, conjunctivitis, etc. are usually seen in viral sore throat infection. Although rapid antigen tests give immediate results, a throat culture is the standard gold test for strep throat.

Treatment For Strep Throat In Children

The following medications can be used to cure the infection, relieve the symptoms, and prevent complications of strep throat in children (3).

  • Oral antibiotics can reduce the severity of strep throat, prevent spread, and reduce the risk of complications if taken within 48 hours of illness. Penicillins and amoxicillin are common antibiotics prescribed.
  • Symptom relievers such as ibuprofen or acetaminophen are given for pain and fever. Aspirin should be avoided since it may cause Reye syndrome in children.

After 24 hours of antibiotic treatment, children can go to school or daycare if there are no symptoms since the infection is not contagious beyond this time. Although the symptoms resolve and the child feels better, it is crucial to complete the prescribed treatment course to avoid recurrence and complications. Consult the doctor if there is no improvement in the child’s condition even after taking antibiotics for 48 hours or two days (10).

Home Remedies For Strep Throat In Children

Home remedies may help to ease symptoms in some children. However, it is advised to take an antibiotic course to fully cure strep throat and avoid future complications.

The following remedies may help ease symptoms and aid faster recovery (6). You may try these measures along with medical treatment.

  1. Getting enough rest during treatment could help in recovery.
  1. Stay hydrated to avoid dry throat that may worsen irritation and throat pain.
  1. Warm salt water gargles can help to soothe the throat.
  1. Try easy-to-swallow foods such as soup, mashed potatoes, yogurt, eggs, cooked cereals, broths, etc. You may also puree food in a blender to make them easy to swallow.
  1. Avoid spicy and acidic foods that may irritate the throat.
  1. Cold foods such as frozen fruit pop, yogurt, etc. can be soothing to the throat.
  1. Avoid irritants such as cigarette smoke, perfumes, fumes of cleaning agents and paints, etc.

Prevention Of Strep Throat In Children

The following tips may help to prevent strep infection in children (6).

  • Wash hands often using soap and water or alcohol-based sanitizer
  • Cover mouth while sneezing or coughing
  • Do not share personal items with infected family members
  • Wash utensils in soapy and hot water
  • Disinfect doorknobs, handles, etc. often

These preventive measures also help to avoid many other infections, such as influenza and COVID-19. Teaching  handwashing techniques and cough etiquette from an early age could protect your child from catching and spreading germs.

Timely diagnosis and treatment of strep throat could help relieve the symptoms and reduce the risk of complications. It is vital to complete the entire antibiotic course for a full recovery. Teach your child preventive steps so they can protect themselves from the infection even at school and daycare.
