WATCH: Dr. Marcia Johnson, Edmonton Zone Medical Officer of Health, speaks about the zones affected by the outbreak.

CALGARY- With a total of 22 cases of measles now confirmed in the province, Alberta Health Services (AHS) is officially declaring a measles outbreak in Calgary, Edmonton and central Alberta.

“Basically we’ve had a month of confirmed measles cases in three zones,” says Dr. Judy MacDonald of AHS. “It doesn’t change how we’ve been handling our response to measles cases, but what it does mean is that we have cases showing up and we can’t identify the source.”

We need to look at additional measures that can provide protection. Tweet This

AHS is now making new recommendations on measles vaccinations.

Children routinely receive measles vaccinations when they are one-year-old and between the ages of four and six. The additional shot will give infants between six and 11 months old added short-term protection because they may no longer be protected by maternal antibodies.

MacDonald warns that infants infected with measles are at an increased risk of complications, which can include pneumonia, hospitalization, and even death.

The province says it will announce plans on Wednesday for special immunization clinics for babies and young children. For more information visit: http://www.albertahealthservices.ca/9842.asp

AHS also says children aged four and up who are attending daycares or schools within the measles zones and who have not yet received their second dose of vaccine, should get it as soon as possible.

MacDonald says this will allow the children to remain in their school or daycare in the event of a measles case.
