Acute Bronchitis is usually caused by viruses, typically the same viruses that cause colds and flu (influenza). Antibiotics don't kill viruses, so this type of medication isn't useful in most cases of bronchitis.

The most common cause of chronic Bronchitis is cigarette smoking. Air pollution and dust or toxic gases in the environment or workplace also can contribute to the condition.

Risk Factors

Factors that increase your risk of bronchitis include:

• Cigarette smoke. People who smoke or who live with a smoker are at higher risk of both acute bronchitis and chronic bronchitis.
• Low resistance. This may result from another acute illness, such as a cold, or from a chronic condition that compromises your immune system. Older adults, infants and young children have greater vulnerability to infection.
• Exposure to irritants on the job. Your risk of developing bronchitis is greater if you work around certain lung irritants, such as grains or textiles, or are exposed to chemical fumes.
• Gastric reflux. Repeated bouts of severe heartburn can irritate your throat and make you more prone to developing bronchitis.

During Sick Visits, healthcare providers offer a range of Services aimed at diagnosing and treating acute illnesses or conditions. These services typically include a thorough evaluation of your child's symptoms, a physical examination, and, if necessary, diagnostic tests such as throat swabs, blood tests, or imaging studies to determine the cause of the illness. Depending on the diagnosis, the provider may prescribe medications, such as antibiotics or antivirals, or recommend over-the-counter treatments to alleviate symptoms.

In addition to diagnosing and treating the illness, the provider will offer guidance on how to care for your child at home, including advice on managing symptoms, administering medications, and when to seek further medical attention. Sick visits also provide an opportunity to address any concerns you may have about your child's health, and the provider may recommend follow-up visits to monitor your child's recovery and ensure that the treatment is effective.
