Yellowknife (Rajeev Sharma): With measles cases on the rise in Alberta, health authorities in the Northwest Territories (N.W.T.) are warning residents about a potential risk of exposure, especially for those traveling through the neighbouring province during the summer.
Dr. Kami Kandola, the territory’s Chief Public Health Officer, emphasized the importance of checking vaccination records, noting that the virus’s resurgence in Alberta could impact northern travelers.
“We’re keeping a close eye on the situation,” Dr. Kandola said. “There’s concern that the infection could make its way north with returning travelers.”
According to Alberta’s latest health data (as of July 24), 1,511 measles cases have been recorded this year. Northern Alberta has reported 465 cases, making it the second most affected area after the south. The north is also a key travel corridor for residents of the N.W.T., further heightening concerns.
Measles Spreads Quickly, Even After Contact Has Left
Measles is a highly contagious airborne virus that can remain in the air or on surfaces for hours after an infected person leaves the vicinity. This makes casual transmission alarmingly easy.
“Measles is very efficient at finding unvaccinated individuals,” explained Dr. Lynora Saxinger, an infectious disease expert at the University of Alberta Hospital. “If you’re not immunized and come near an active case, there’s a 90% chance you’ll catch it.”
Dr. Saxinger also noted that the actual spread could be broader than official figures suggest, as many individuals may be recovering at home without seeking medical care. “We’re likely underestimating the true number of infections,” she added.
Local Vigilance and Community Awareness
Despite the concern, Dr. Kandola believes the situation in the N.W.T. may be easier to track due to the territory’s close-knit communities.
“In smaller communities, if someone shows up with a classic measles rash, red and blotchy, people will talk. Word spreads quickly,” she said. “That increases the likelihood that any case would be detected sooner rather than later.”
However, some areas remain more vulnerable than others. According to Kandola, the Tlicho region has the lowest childhood immunization rate, with just 77% of five-year-olds having received at least one dose of the measles vaccine. In contrast, other regions report rates above 90%.
As the summer travel season continues, health officials are urging residents to stay informed and ensure their vaccinations are up to date.
“Prevention is key,” Kandola stressed. “Vaccination remains our strongest tool in stopping the spread of measles.”
