The Prince Albert region in Saskatchewan is experiencing a concerning rise in the number of Lyme disease-carrying ticks, according to a University of Saskatchewan researcher. This trend is particularly alarming due to the potential health risks associated with these ticks. While the overall tick population remains low compared to eastern Canada, the presence of blacklegged ticks and their ability to carry Lyme disease cannot be ignored.
One of the key findings is that the eTick program, which allows residents to report ticks and receive information about potential diseases, has revealed a significant increase in tick submissions. Between 2009 and 2017, the region averaged around six to seven blacklegged ticks per year. However, in 2023, researchers received approximately 30 blacklegged ticks, and the number jumped to about 50 in 2024. This data suggests a growing tick population, which is concerning given the potential for Lyme disease transmission.
Dr. Zoordouw, the researcher leading the eTick program, emphasizes that the region still does not have an established blacklegged tick population. The absence of larvae and nymphs in the tick submissions indicates that migratory birds are likely bringing immature ticks from the United States, where they mature into adults in Saskatchewan. This highlights the interconnectedness of ecosystems and the potential for disease spread across borders.
Despite the relatively low number of ticks, the risk of Lyme disease should not be overlooked. The majority of Lyme disease cases in Saskatchewan are linked to travel to other provinces or countries where blacklegged ticks are more prevalent. Between 2019 and 2024, there have been 12 reported cases of Lyme disease in the province. This data underscores the importance of awareness and prevention measures.
The eTick program plays a crucial role in monitoring tick activity and providing valuable information to residents. By submitting tick photos, residents can receive species identification and disease risk assessments. Interestingly, most of the ticks submitted in Saskatchewan are American dog ticks, which do not carry Lyme disease but can transmit other illnesses like Rocky Mountain spotted fever. A recent case near Emma Lake serves as a stark reminder of the dangers associated with these ticks.
Zoordouw advises residents to be vigilant, especially during the fall months when blacklegged ticks are most active. Unlike American dog ticks, which are primarily active from April to July, blacklegged ticks can be found on people and pets as late as early December. This knowledge is essential for timely tick removal and potential disease prevention.
However, diagnosing Lyme disease in Saskatchewan can be challenging due to the region's perceived low-risk status. Doctors may not consider testing for Lyme disease if they believe there are no blacklegged ticks in the province. The eTick program can help bridge this gap by providing evidence of tick species, aiding in patient diagnosis and treatment.
In conclusion, the Prince Albert region's increasing tick population and the potential for Lyme disease transmission demand heightened awareness and proactive measures. By understanding the behavior of these ticks and utilizing programs like eTick, residents can take control of their health and contribute to a safer, more informed community.
