What causes pharyngitis?

In most cases, pharyngitis is caused by viral infections, such as influenza (flu) and mononucleosis. However, it can also be the result of a bacterial infection such as strep throat, an allergic reaction, or gastric reflux. Pharyngitis can also develop from an environmental irritant or injury. Bacterial and viral pharyngitis are usually contagious. If you have lowered immunity, as in the case of HIV infection, you may be more susceptible to infections that lead to pharyngitis.

What are the risk factors for pharyngitis?

A number of factors increase the risk of developing pharyngitis. Not all people with risk factors will get pharyngitis. Risk factors for pharyngitis include:

  • Advanced or very young age
  • Closed-in work or living spaces
  • Exposure to chemical irritants
  • Exposure to highly populous areas
  • Gastroesophageal reflux disease (GERD)
  • Lowered immunity

Reducing your risk of pharyngitis

You can lower your risk for developing or transmitting pharyngitis to others by:

  • Avoiding contact with tobacco and chemical irritants
  • Avoiding sharing food and eating utensils, cups, and glasses
  • Treating any allergies conscientiously
  • Using sanitizing agents on shared surfaces
  • Ventilating work and living spaces as much as possible
  • Washing your hands frequently
