Utahns of nearly every age have been affected in this outbreak. This includes kids who are too young for school (24 infections in kids younger than age 5), kids in elementary school (32 infections in kids 5-12), junior and high school students (30 infections in teens 13-18), young adults (28 infections in people 19-25) and adults (20 infections in people older than age 25).
And these infections are not minor. We have people of all ages being hospitalized. Fifteen people younger than 18 years old have had to either go to the hospital or the emergency department for medical care related to their measles. Most of these hospitalizations have been short, but I would prefer no one is hospitalized for this preventable disease.
Our team at the Utah Department of Health and Human Services is very careful about making sure people can’t be identified by the information we put out. Therefore, we have only been reporting the ages of people with measles on our website as 2 categories: Older than 18 and younger than 18 years old. We will continue to report ages in that way on our website and provide static updates when appropriate.
