When you have asthma, any upper respiratory infection -- like a cold or the flu -- can affect your lungs, causing inflammation and airway narrowing. It is important to take measures to stay healthy and be aware of any asthma symptoms, even mild, so that you avoid a more serious asthma attack.
What Are the Symptoms of Infection?
Call your doctor if you experience any of the warning symptoms of a possible infection that can trigger an asthma attack (listed below). Also call your doctor if you have any other symptoms of an asthma attack that cause concern.
- Increased shortness of breath, difficulty breathing, or wheezing
- Coughing up increased amounts of mucus
- Abnormally colored mucus
- Fever (temperature over 101°F) or chills
- Increased fatigue or weakness
- Sore throat, scratchy throat, or pain when swallowing
- Sinus pressure or drainage, nasal congestion, or headaches
How Can I Prevent Infections That Trigger Asthma?
- Good hygiene can decrease viral infections. Prevent the spread of infection by making sure you and your family members wash their hands regularly with soap and warm water.
- Check with your health care provider about receiving a flu shot every year. In addition, discuss the possibility of getting a pneumococcus -- or pneumonia -- vaccine. Pneumococcus is a common cause of bacterial pneumonia, an illness that can be particularly serious in a person with asthma. Depending on your age and any risk factors you may have, you may need two different types of pneumonia vaccines.
- Sinusitis with asthma can be very serious. Be aware of the symptoms of a sinus infection and report them immediately to your asthma specialist to prevent asthma attacks.
- Keep breathing equipment clean. Do not let others use your asthma medications or asthma treatment, including your asthma inhaler, asthma nebulizer, and nebulizer tubing and mouthpiece.
