Why is flu a danger to those with heart disease?

Flu and lung infections pose greater dangers for people with heart disease. Lung infections prevent people from taking in oxygen as efficiently as they should. This makes the heart work harder to pump oxygen-rich blood through the body. This extra work can be dangerous for people with heart disease.

For in-depth information, see WebMD's Heart Disease and Flu.

What about HIV/AIDS and flu?

The human immunodeficiency virus (HIV) kills or damages cells in the body's immune system. It gradually destroys the body's ability to fight infections like the flu and the common cold. About 1.1 million people are infected with HIV in the U.S., according to the CDC. People with HIV are more likely to get complications from the flu, such as pneumonia. They are also at higher risk of dying from the flu.

For in-depth information, see WebMD's HIV/AIDS and Flu.

Are elderly adults at higher risk for flu complications?

More than 90% of flu-related deaths occur among the elderly (adults more than 65 years of age) In addition, many older adults suffer with illnesses such as diabetes, heart disease, and COPD, which also increase the chances of flu complications.

For in-depth information, see WebMD's Flu in Older Adults.

What about pregnant women and flu complications?

Pregnancy can increase the risk of flu complications. That's why it's important to understand flu symptoms and contact your physician immediately to avoid potentially serious flu complications. In addition, pregnant women and those who intend to become pregnant during flu season are urged to get a flu shot.

For in-depth information, see WebMD's Pregnancy and Flu.

How can you prevent the flu when you have a chronic medical condition?

Getting a flu shot is the best way to prevent the flu. The flu vaccine is highly recommended for healthy individuals who want to avoid flu and for those people who are in high risk groups. Only infants younger than 6 months should not get a flu shot.
