Acute bronchitis is a contagious viral infection that causes inflammation of the bronchial tubes. These are the airways that carry air into your lungs. When these tubes get infected, they swell. Mucus (thick fluid) forms inside them. This narrows the airways, making it harder for you to breathe.
There are 2 types of bronchitis: acute and chronic. Chronic bronchitis is long-lasting and can reoccur. It usually is caused by constant irritation, such as from smoking. Acute bronchitis lasts only a short time. Most cases get better in several days, though the cough can last for several weeks.
You can help prevent acute bronchitis by staying healthy and avoiding germs. Wash your hands with soap often to kill any contagious viruses.
If you smoke, the best defense against acute bronchitis is to quit. Smoking damages your bronchial tubes and puts you at risk for infection. Smoking also slows down the healing process.
Other steps you can take to avoid acute bronchitis include:
Wear a mask over your nose and mouth when using lung irritants. These could include paint, paint remover, or varnish.
