Exposure locations
Information about measles in Utah
As cases are reported, public health officials in Utah investigate to identify individuals who are at risk of infection and any locations where possible exposures may have occurred. These exposure locations can be found in the table above.
Measles symptoms typically appear 7 to 14 days after exposure. People who have a high fever (101°F (38.3°C) or higher) and a cough, runny nose, or red eyes may have early stages of measles. A rash will usually appear after 4 days of fever. If you do develop symptoms you should stay away from other people and call your healthcare provider. Call first before you go to a clinic or hospital to prevent other people from exposure.
