Nearly 1 in 3 Americans will develop a shingles infection at some point in their lifetime, according to statistics from the Centers for Disease Control and Prevention. While shingles is often associated with those over the age of 50, anyone who has had chickenpox is at risk for developing the viral infection, even children on rare occasions.

Pneumonia is a respiratory condition that is caused by an infection of one or both lungs. This is an illness that affects more than a million people each year in the United States.
