Sore throat:

A symptom of infection 1

Oral and throat infection is a common term used to define many different infections of the mouth and throat. A sore throat is a symptom of inflammation of the pharynx (pharyngitis) or tonsils (tonsillitis), or both (Pharyngotonsillitis). These infections spread through close contact with others. Pharyngotonsillitis can include irritation, itching, and pain that can make it difficult to swallow.





What causes oral and throat infections? 2,3


Did you know that there are two causes of a sore throat?

• 85% of sore throats in adults and children are caused by viruses (commonly called colds and flu)
• Less than 15% are caused by bacteria

Viruses commonly known to cause sore throats

Sore throat risk factors 3

Anyone can get a sore throat but these factors can increase your risk:
• Age (children and teens 5 – 15 years old are most likely to get a sore throat)
• Exposure to someone with an oral and throat infection
• Time of year (winter and early spring)
• Weather (cold air may irritate your throat)
• Irregularly shaped tonsils or large tonsils
• Pollution or exposure to smoke
• A weak immune system (prescription medication may weaken the immune system)
• Post-nasal drip or allergies
• Acid reflux disease

Sometimes there may be an overlap in clinical manifestations (how the symptoms present themselves). This means that differentiating between viral and bacterial infections can be challenging.

How to treat a sore throat?

The usual duration of a sore throat is 5-7 days. As most sore throats are viral they do not require an antibiotic prescription.3  In fact, oral or systemic antibiotics in common colds and sore throat are associated with marginal or no benefit to patients. 7,8
