Understanding Acute Bronchitis

What is Acute Bronchitis?

Acute bronchitis is an inflammation of the bronchial tubes, the major airways into the lungs. It may be caused by a variety of bacteria and viruses. These viruses can be spread in the air when a person coughs. They also can be spread through physical contact, such as through unwashed hands.

How Serious is Acute Bronchitis?

Acute bronchitis can last from a few days to 10 days. But the cough that comes with acute bronchitis may last for several weeks after the infection has gone.

What Causes Acute Bronchitis?

Acute bronchitis may develop on its own, or as a result of an upper respiratory infection, pertussis (whooping cough) or other infection.
