How can I help prevent acute bronchitis?

You can help prevent acute bronchitis.

• Avoid cigarette smoke. If you smoke, stop. People who smoke or are around others who smoke have more frequent bouts of acute bronchitis. Smoke (including secondhand smoke) reduces the body's ability to remove bacteria and viruses that can cause infections in the lungs.
• Wear a face mask while working around irritants, such as dust. Specially designed masks are available to filter out dangerous chemicals or dust.
• Avoid contact with those who have an upper respiratory tract infection, such as a cold, especially if you have an impaired immune system or another medical condition. Wash your hands often during the cold and flu season. If you catch a cold or influenza (flu), you are at an even higher risk for getting bronchitis.
• Discuss with your doctor whether you should get a vaccine for the flu.

If you have an upper respiratory tract infection, it may help to:

• Get plenty of rest.
• Drink enough liquids to avoid getting dehydrated.
