Shingles
About one out of three Americans will develop shingles, which is caused by the same virus that triggers chickenpox. Although anyone who’s had chickenpox is at risk for shingles at any point in their life, about half of all cases involve people 60 or older, according to the Centers for Disease Control and Prevention. The main symptom is a painful rash that develops on one side of the face or body, with blisters that scab over in about a week. The only way to reduce the risk is to get vaccinated, so the CDC recommends people 60 and older get the shingles vaccine regardless of whether or not they recall having had chickenpox.
