What to Know About Pneumonia and Older Adults

Over 50,000 people in the U.S. die from pneumonia in a typical year.

Clinton's doctor said that the presidential hopeful "became overheated and dehydrated" and that "she is now rehydrated and recovering nicely," adding that she was advised to rest and modify her schedule.

For many Americans, getting pneumonia can lead to serious consequences, especially for young children and the elderly.

Globally, pneumonia kills nearly 1 million children younger than 5 years of age each year, but most people seriously affected by pneumonia in the U.S. are older adults.

The overall death rate for pneumonia in the United States is 16.9 per 100,000 people, and that rate rises dramatically with age, to 27.9 for people from 65 to 74, 98.6 for people 75 to 84 and 414.7 for people 85 or older.

The CDC says you can lower your risk for getting pneumonia by getting vaccinated and doing the following:

Wash your hands regularly.

Clean surfaces that are touched a lot.

Cough or sneeze into a tissue or into your elbow or sleeve.

Limit contact with cigarette smoke.
