Heart disease, diabetes, and COPD are among the most common long-term illnesses. Learn how each can elevate your risk for a life-threatening, flu-related complication.
People with heart disease, including congestive heart failure and coronary artery disease, have a higher risk for serious complications from the flu. During the 2018–2019 flu season, 47% of adults hospitalized with the flu also had heart disease.
In patients with heart failure,
flu vaccination may be related to a 50%
reduction in risk of dying from a flu-related illness during the flu season.
Diabetes can weaken the immune system, making it harder to fight the flu. Having the flu can make it difficult to control blood sugar levels, which can rise from the infection or fall if a person is not eating, causing risk for serious complications.
Diabetes patients who receive a flu vaccine have been
shown to reduce their risk of hospitalizations:
19% for heart attack, 30% for stroke, and 15% for pneumonia or flu.
Chronic lung diseases like COPD and ASTHMA cause airways to swell and become blocked with mucus. Influenza can also increase swelling of airways and lungs, leading to respiratory illnesses.
Flu vaccination has been shown to reduce hospitalization rates among people with chronic lung disease.
Other chronic conditions that can make adults more susceptible to complications from the flu include:
