by Jill Shuman, MS, RD, ELS
Acute bronchitis is a short term lung infection. Bronchi in the lungs become inflamed and start to make more phlegm than normal. It leads to intense coughing.
Viruses are the most common cause of infection. Bacteria can also cause it, but this isn’t as common.

Your risk is higher if you:
Common symptoms may cause:
The doctor will ask you about your symptoms and health history. Your answers may point to acute bronchitis. You may need further testing only if the doctor suspects something else such as pneumonia. This is normally not done.
The infection will go away on its own. Care focuses on making you feel better until the infection passes. The cough can last for up to a month.
Care may involve:
Note : Check with your child’s doctor before giving them aspirin. It’s not a good option if they have or had a viral infection. The Food and Drug Administration (FDA) advises not using cough suppressants in children less than 2 years old. The FDA also supports not using them in children less than 4 years old.
