More than half of the cases of bronchitis that are due to an infection have been reported to be associated with viruses. Of course, the number of bronchitis infections due to viral infections can vary depending on the time or season of the year. Antibiotics are unlikely to be of great benefit to treat bronchitis caused by a virus. Initial treatment for a majority of bronchitis cases should be directed towards symptom control. Staying hydrated, avoiding noxious inhaled stimuli (for example, tobacco smoke) and other over-the-counter cough medications can be beneficial during the recovery phase.
