People at High Risk For Flu Complications
Most people who get sick with flu will have mild illness, will not need medical care or antiviral drugs and will recover in less than two weeks. Some people, however, are more likely to get flu complications that can result in hospitalization and sometimes death. Pneumonia, bronchitis, sinus infections and ear infections are examples of flu-related complications. Flu also can make chronic health problems worse. For example, people with asthma may experience asthma attacks while they have flu and people with chronic congestive heart failure may experience a worsening of this condition triggered by flu. Below are the groups of people who are more likely to get serious flu-related complications if they get sick with flu.
Following is a list of all the health and age factors that are known to increase a person’s risk of getting serious complications from the flu:
- Neurologic and neurodevelopment conditions
- Blood disorders (such as sickle cell disease)
- Chronic lung disease (such as chronic obstructive pulmonary disease [COPD] and cystic fibrosis)
- Endocrine disorders (such as diabetes mellitus)
- Heart disease (such as congenital heart disease, congestive heart failure and coronary artery disease)
