Pharyngitis and tonsillitis are infections in the throat that cause inflammation.

If the tonsils are primarily affected, it is called tonsillitis.

If the throat is primarily affected, it is called pharyngitis.

A child might even have inflammation and infection of both the tonsils and the throat. This would be called pharyngotonsillitis.

These infections are spread by close contact with other individuals. Bacterial infections are more common during the winter. Viral infections are more common in summer and fall.

Facts about Pharyngitis and Tonsillitis

Pharyngitis and tonsillitis are most commonly seen in school-aged children.

Children under age 2 rarely develop group A ß-hemolytic streptococcus (GABHS), or strep throat.

Causes of Pharyngitis and Tonsillitis

There are many causes of infections in the throat. The following are the most common infectious agents:

Viruses

• Adenovirus
• Influenza virus
• Epstein-Barr virus
• Herpes simplex virus  

Bacteria

• Group A ß-hemolytic streptococci (GABHS)
• Neisseria gonorrhea
• Haemophilus influenzae type B
• Mycoplasma

Fungal Infections

Parasitic Infections

Cigarette Smoke

Signs and Symptoms

The symptoms of pharyngitis and tonsillitis depend greatly on the cause of the infection and the person affected. For some children, the onset of symptoms may be quick; for others, symptom onset is slow. The following are the most common symptoms of pharyngitis and tonsillitis. However, each child may experience symptoms differently. Symptoms may include:

• Sore throat
• Fever (either low grade or high)
• Headache
• Decrease in appetite
• Not feeling well
• Nausea
• Vomiting
• Stomach ache
• Painful swallowing
• Visual redness or drainage in the throat

Diagnosis of Pharyngitis and Tonsillitis

In most cases, it is hard to distinguish between a viral sore throat and a strep throat based on physical examination. It is important, though, to know if the sore throat is caused by GABHS, as this requires antibiotic treatment to help prevent the complications associated with these bacteria.

As a result, when most children have these symptoms, they will receive a strep test and throat culture to determine if it is an infection caused by GABHS. This usually involves a throat swab (called quick tests or rapid strep tests) in the physician's office.

This may immediately become positive for GABHS and antibiotics will be started. If it is negative, part of the throat swab will be kept for a throat culture. This will further identify, in two to three days, if there is any GABHS present. Your child's physician will decide the treatment plan based on the findings.

Treatment for Pharyngitis and Tonsillitis

Specific treatment for pharyngitis and tonsillitis will be determined by your child's physician based on:

• Your child's age, overall health, and medical history
• Extent of the condition
• Cause of the condition
• Your child's tolerance for specific medications, procedures, or therapies
• Expectations for the course of the condition
• Your opinion or preference

If bacteria do not cause the infection, then the treatment is focused on the comfort of your child. Antibiotics will not help treat viral sore throats. Treatment may include:

• Acetaminophen (such as Tylenol, for pain)
• Increased fluid intake
• Throat lozenges
• Antibiotics (if the cause of the infection is bacterial, not viral)
