How common is fever in acute bronchitis?

Acute bronchitis involves inflammation of the breathing tubes, often after a viral respiratory infection. A raised temperature may occur with a cough, phlegm, sore throat, tiredness, wheeze, or soreness in the chest from coughing. The temperature and cough do not by themselves establish the cause of the illness.

Fever can also occur with influenza, COVID-like respiratory infections, pneumonia, and infections outside the chest. The overall pattern, how quickly symptoms change, and examination findings help a clinician distinguish between them.

Rest, take regular fluids, and use a room that is comfortably cool. A pharmacist can help you choose a fever or cough treatment that suits your age and any regular medicines. Avoid smoking and smoky environments, which can irritate already inflamed airways.

Keep track of breathing effort, hydration, and whether the cough or fever is getting worse rather than gradually settling. Contact a clinician if symptoms are not following an expected recovery course or you have underlying lung disease.

Seek urgent assessment for shortness of breath at rest, chest pain, coughing up blood, confusion, fainting, blue or grey lips, or inability to drink enough fluids. Prompt advice is sensible for a fever with worsening breathlessness, for symptoms in a very young child, or for people with significant heart, lung, or immune conditions.

Ask whether your breathing and chest examination suggest acute bronchitis or another condition, whether any tests are needed, and which fever or cough medicines are safe with your other treatments. Ask when persistent cough or new breathing symptoms should be reassessed.
