Flu and Chronic Medical Conditions
If you have a chronic medical condition such as heart disease, asthma, or diabetes, it's important to call your doctor when the first flu symptoms occur.

These complications can include bacterial pneumonia, dehydration, and worsening of chronic medical conditions such as congestive heart failure, asthma, or diabetes. When kids with asthma or allergies get flu, they often get complications such as sinus problems and ear infections.

- adults and children 6 months and older with chronic heart or lung conditions, including asthma
- adults and children 6 months and older who needed regular medical care or were in a hospital during the prior year because of a metabolic disease (such as diabetes), have chronic kidney disease, or have a weakened immune system -- including immune system problems caused by medicines or by infection with human immunodeficiency virus (HIV/AIDS)

- asthma
- diabetes
- emphysema
- heart disease
- HIV/AIDS
Why is flu more serious to those with asthma?
Asthma is a chronic lung disease. It affects more than 22 million Americans. Flu can make asthma symptoms much worse.
According to the American Lung Association, only 40% of adults with asthma and 10% of children with asthma actually get the flu shot, despite longstanding recommendations that they do so. A study by the American Lung Association estimates that if every child with asthma got the flu shot, it would prevent approximately 100,000 hospitalizations each year.

What about diabetes and flu?
While getting the flu is dangerous for anyone, it's extra risky for those with diabetes. People with diabetes are three times more likely to die with flu and/or pneumonia. Still, more than 50% of those with diabetes do not get an annual flu shot, according to the CDC.

How is COPD -- emphysema and chronic bronchitis -- worsened by flu?
Emphysema and chronic bronchitis, known together as chronic obstructive pulmonary disease (COPD), affect 10.7 million adults. Both conditions are marked by obstruction to airflow that interferes with breathing. Like asthma or any lung disease, COPD is worsened by the flu. if you have COPD, it's important to learn what you can do to avoid respiratory problems.
