What is an upper respiratory infection?

An upper respiratory infection (URI) is also called an upper respiratory tract infection. It’s a contagious illness that affects your nose, throat and sinuses. It’s commonly caused by a virus but it can also be caused by bacteria.

Common types of upper respiratory infections include:

  • Common cold
  • Sinusitis
  • Pharyngitis (sore throat)
  • Laryngitis (voice box inflammation)

Upper Respiratory Infection Symptoms

Upper respiratory infection symptoms vary depending on the cause but often include:

  • Coughing and sneezing
  • Nasal congestion or discharge
  • Throat irritation or hoarseness
  • Low-grade fever
  • General fatigue or body aches

If your symptoms worsen after a few days or last more than 10 days, it could be a sign of a bacterial infection or another condition that needs medical attention.
