EDMONTON – Measles disease activity in the Edmonton Zone of Alberta Health Services (AHS) has decreased to such an extent as to meet criteria necessary to lift the measles outbreak first declared on April 29, 2014. Effective immediately, AHS has declared this measles outbreak over in the Edmonton Zone of AHS.
Though standard measles surveillance and followup work undertaken by AHS will continue across all Zones, temporary changes to the routine childhood immunization schedule – implemented for the duration of this outbreak only – are no longer in effect in the Edmonton Zone.
Effective immediately, AHS will no longer offer an early additional dose of measles vaccine to infants six months of age to less than 12 months of age who are living in or travelling to the Edmonton Zone of AHS. This additional early dose of measles vaccine was recommended while the outbreak was active in the Edmonton Zone as a means of offering short-term added protection during that time of increased risk of exposure to disease.
As the outbreak declaration has been lifted in the Edmonton Zone, requests for early additional doses of measles vaccine will no longer be accommodated. Appointments (for this additional early dose) that had already been booked prior to July 4, 2014, will be honored, going forward. Additionally, infants travelling to other areas (within Canada or abroad) in which measles outbreaks are occurring will also remain eligible to receive an additional early dose of vaccine if this travel cannot be avoided.
A measles outbreak can be declared over when 42 consecutive days have passed since the last date of infectiousness of the last confirmed case of measles in a Zone, and no new cases of measles have been confirmed in that Zone in that same 42 day period.
Although it has been more than 42 days since the last date of infectiousness of the last confirmed cases of measles in the Edmonton Zone, and no new cases of measles have been confirmed, measles does continue to circulate in Alberta and worldwide. Without immunization, Albertans may be at risk of contracting this potentially severe illness.
AHS continues to advise all Albertans to ensure they are up to date on their immunizations, including measles vaccine.
Measles vaccine is available, free of charge, through Alberta’s publicly-funded immunization program:
Additionally, Alberta children age four and older who are attending daycares/dayhomes and schools, and who have not yet received their second dose of measles vaccine are recommended to receive this second dose as soon as possible. By ensuring children who attend daycares/dayhomes and schools receive this second dose as close to the age of four as possible, the ongoing risk of these children being excluded from these facilities if exposed to measles is greatly reduced.
Albertans uncertain about their immunization history, or their child’s immunization history, are reminded to contact their local public health office or Health Link Alberta (1-866-408-5465) to discuss immunization needs.
