A respiratory illness is a disease that affects a person’s lungs or breathing. Viruses are a common cause of respiratory illness, especially during fall and winter — sometimes called “cold and flu season.”

 

Examples of respiratory illnesses caused by viruses include:

  • Common colds (rhinovirus, coronavirus, and other viruses)

  • Flu (influenza viruses)

  • RSV (respiratory syncytial virus)

  • COVID-19 (novel coronavirus:  SARS-CoV-2)

Symptoms

Different respiratory illnesses have different symptoms. Runny nose, coughing, sneezing, tiredness, fever, and sore throat are all symptoms commonly associated with seasonal respiratory illnesses. Learn more about symptoms of colds, flu, RSV and COVID-19.

Note: "Stomach flu" or "stomach bugs" involving diarrhea and vomiting are not typically related to influenza (flu).  "Stomach flu" is often caused by norovirus, an extremely contagious virus that causes gastrointestinal illness.
