If you think you or your family member have symptoms of measles​, call your doctor before going to the office so staff can take measures to prevent possible spread to other patients.  Do not go to child care, school, work, or out in public if you have symptoms of measles. If you think you or a family member might have been exposed to measles, or if you have questions about vaccinations, contact your healthcare provider. ​​
