An upper respiratory infection (URI) is an illness caused by an infection of the upper air passages from a virus or bacterial infection. URIs are the number one reason for doctor visits.

Causes

Respiratory-SystemURI is caused by a virus or bacteria in the upper air passages. The upper air passages include the sinuses, nasal passages, larynx and pharynx.

Viruses cause illnesses like the common cold and bacteria causes illnesses like strep throat. Both can start an URI.

The virus or bacteria is usually spread by breathing air or touching something with virus or bacteria germs.

Different viruses and bacteria take different lengths of time to make you feel sick and URIs can last 3-14 days.

Symptoms

  • Congestion
  • Cough
  • Facial pain or pressure
  • Fever
  • Headache
  • Runny nose
  • Sneezing
  • Sore throat

Risk Factors

Some risk factors for getting URI are:

  • Close contact with someone who is infected with URI
  • Not washing your hands after contact with a person who has a URI
  • Close contact with groups of children in a school or daycare centers
  • Contact with large groups in a closed setting like an airplane, bus, or boat
  • Smoking or second-hand smoke
  • Spending time in health care centers, hospitals, or nursing homes
  • Having a compromised immune system such as from having HIV, an organ transplant, congenital immune defects, or long term steroid use
  • Abnormalities in your upper airways from facial trauma, upper airway trauma or nasal polyps

Antibiotic Treatment

Antibiotics do work against bacteria and can be prescribed for bacterial infections. Antibiotics do not work against viruses and should not be used to treat viruses.

Although antibiotics are not used to treat viruses, your health health care provider may need to give you antibiotics to treat URI even if it was started by a virus.
