Alberta researchers are using wastewater to detect measles amid growing outbreaks. Experts hope it could become a key early-warning tool for public health.
Researchers Monitor Measles in Alberta Wastewater
In response to Alberta’s escalating measles outbreaks, scientists have begun analyzing the province’s wastewater for traces of the virus—hoping to use it as an early warning system.
Detection Linked to COVID-Era Surveillance Network
Starting in April 2024, a team of researchers from the University of Alberta and the University of Calgary adapted existing COVID-19 wastewater testing infrastructure to include measles detection. Using samples from 12 municipal wastewater treatment sites, they identified signs of measles virus activity—confirming the virus has been circulating for several months.
Rising Infections Fuel Public Health Concern
As of mid-July, over 1,300 measles cases have been reported since the outbreak began in March. Scientists believe the real number may be higher, citing underreporting in affected areas. According to health experts, most of the infections are in unvaccinated individuals, with more than 100 people hospitalized so far.
Potential for Early Outbreak Detection
Dr. Xiaoli Pang, a key developer of Alberta’s COVID-19 wastewater monitoring system, also created the test now used for measles. She believes the incubation period of up to two weeks may allow health officials to detect virus trends before clinical cases surge—just as they did with SARS-CoV-2 during the pandemic.
Limitations and Need for Continued Investment
Although promising, the researchers emphasize that wastewater surveillance should be used as a complementary tool, not a standalone solution. Current limitations include weekly—not daily—testing and a lack of real-time data. With waning funding post-pandemic, researchers stress the need for renewed investment to support broader and more frequent testing.
Government Reviewing Early Findings
Preliminary data has been shared with Alberta’s public health authorities. The provincial government acknowledged it is reviewing the information to determine its role in ongoing outbreak management.
Future of Wastewater Surveillance
Experts say wastewater monitoring could help identify emerging pathogens in the future, potentially detecting outbreaks before they spread widely. As concerns grow over infectious disease threats, researchers advocate for its integration into Canada’s long-term public health strategy.
“Wastewater is a powerful tool. We can’t afford to lose it,” said Dr. Pang.
