Suspected or Confirmed Cases of Measles
Isolate suspected or confirmed cases of measles immediately into a single room with closed door. Refer to WECHU’s Clinical Office Checklist for Measles to prepare the clinical office for a patient with suspected measles.
HCPs are required to report suspected cases to the WECHU immediately and complete the Measles Investigation and Reporting form the SAME day as the initial patient visit.
If a patient’s immunization records are unavailable, immunization with measles-containing vaccine is preferable to ordering serological testing to determine immune status.
For support or consultation, please call 519-258-2146 ext. 1420.
