Is Bronchitis contagious?

🩺 What Is Bronchitis?

Bronchitis is a common respiratory condition characterized by inflammation of the bronchial tubes, which carry air to the lungs. It causes a persistent cough, chest discomfort, and mucus production. It can be either acute or chronic, and understanding the difference is key to determining whether it’s contagious.

❓ Is Bronchitis Contagious?

The answer depends on the type of bronchitis:

✅ Acute Bronchitis: Contagious

• Caused by viral infections like the common cold or flu.
• Spreads through coughing, sneezing, or touching contaminated surfaces.
• Contagious in the first few days after symptoms begin.

❌ Chronic Bronchitis: Not Contagious

• A form of COPD (Chronic Obstructive Pulmonary Disease).
• Caused by long-term exposure to irritants such as smoking or pollution.
• Not infectious and cannot be passed to others.
