Vancouver health authorities confirmed two new cases of measles in the city, separate from the ongoing outbreak linked to two francophone schools.
The two individuals contracted measles while travelling and are unrelated to the outbreak that began at École Jules‐Verne and École Rose-Des-Vents.
The update came the same day Alberta Health Services issued a measles exposure warning in that province, after a passenger with measles travelled from Vancouver to Edmonton on an Air Canada flight earlier this month.
According to AHS, an individual with a confirmed case of measles was found to have visited Leduc, Alta. while infectious. The person boarded Air Canada flight AC236 departing from Vancouver International Airport on Tuesday, Feb. 12 at 10:25 a.m. and landed at Edmonton International Airport around 12:54 p.m.
The infected traveller then took an airport shuttle, which dropped off travellers to Paradise Inn and Suites, Crystal Star Inn, Wyndham Garden Edmonton Airport, and Wingate by Wyndham between 2:30 to 3:30 p.m.
Other exposure times include Feb. 12 at Walmart Supercentre (5 to 7 p.m.); Feb. 13 on board an airport shuttle pickup from Crystal Star Inn (6:30 to 7a.m.), a Canadian North Flight #5T-444 to Inuvik departing from Edmonton airport around 7:45 a.m.; Feb. 12 and 13 at Stars Inn Hotel (3 p.m. to 6:30 a.m.)
“Given the timeframe of the potential exposure, post-exposure immunization is not effective,” read a AHS health advisory.
“Individuals are encouraged to monitor for symptoms for 21 days after the date of potential exposure, which could be up to March 5, 2019.”
VCH is expected to provide an update Sunday afternoon about the new cases of measles.
A measles outbreak is underway in Vancouver, after an unvaccinated child contracted the disease during a trip to Vietnam last month. The child visited B.C. Children’s Hospital and returned to school in late January and early February, prompting Vancouver Coastal Health to issue a warning.
Up to 36 people linked to the child’s school have been ordered to stay at home because they are either unvaccinated and are waiting out the incubation period, or have been able to provide proof of immunization.
