Infection Prevention And Control (IPAC) Measures

• Continue to screen patients over the phone for signs/symptoms of measles at the time of booking an appointment, making efforts to arrange appointments for symptomatic patients at the end of the day, when no other patients are present. Encourage patients to wear a well-fitting, high-quality mask when seeking medical assessment.
• 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.
• Use your point of care risk assessment to determine the safest testing process.   
• Encourage measles vaccination for all unvaccinated and at-risk individuals and continue to ensure that clients are kept up to date and vaccines are given on time, in accordance with the publicly funded schedule, to ensure protection as early and effectively as possible.
• Remind parents/guardians to submit up-to-date immunization records for their children to the WECHU as required in the Immunization of School Pupils Act (ISPA).

Post-Exposure Prophylaxis

For contacts of measles cases, ensure any individuals identified as having been exposed to 

measles are instructed to contact the WECHU to be assessed for eligibility for post-exposure prophylaxis.
