Asthma Symptoms, Causes, and Medications

What are the symptoms of upper respiratory infection?

Generally, the symptoms of upper respiratory infection result from the toxins released by the pathogens as well as the inflammatory response mounted by the immune system to fight the infection.

Common symptoms of upper respiratory infection generally include:

  • nasal congestion,
  • runny nose (rhinorrhea),
  • nasal discharge (may change from clear to white to green)
  • nasal breathing,
  • sneezing,
  • sore or scratchy throat,
  • painful swallowing (odynophagia),
  • cough (from laryngeal swelling and post nasal drip),
  • malaise, and
  • fever (more common in children).

Other less common symptoms may include

The symptoms of upper respiratory infection usually last between 3-14 days; if symptoms last longer than 14 days, an alternative diagnosis can be considered such as, sinusitis, allergy, pneumonia, or bronchitis.

Bacterial pharyngitis (strep throat due to group A Streptococcus) may be considered if symptoms continue to worsen after the first week in the absence of runny nose, cough, or conjunctivitis. Prompt testing and initiation of appropriate antibiotics is important due to the risk of developing rheumatic fever, especially in children.

Epiglottitis is an upper respiratory infection in children that may have a more sudden onset of sore throat, feeling of a lump in the throat, muffled voice, dry cough, very painful swallowing, and drooling.

Upper respiratory infections in the lower part of the upper respiratory tract, such as, laryngotracheitis, are more commonly featured with dry cough and hoarseness or loss of voice. Barking or whooping cough, gagging, rib pain (from severe cough) are other symptoms and signs. Continue Reading
