Lyme disease isn’t the only concern as tick-borne illness rises in Nova Scotia

Nova Scotia is experiencing a surge in tick-related illnesses beyond the well-known Lyme disease, with reports indicating a notable increase in cases of anaplasmosis. As of July 26, the province has documented 400 cases of anaplasmosis this year alone, surpassing the total of 681 cases recorded throughout 2025 and exceeding the 466 cases from 2024. The provincial health authorities attribute this upward trend to environmental factors, particularly the effects of climate change, which have led to milder winters and extended warm seasons, thereby enabling ticks to remain active for longer periods. This increased activity heightens the likelihood of human exposure to ticks, raising public health concerns. Experts such as Nicoletta Faraone, director of the Canadian Tick Research and Innovation Centre and professor at Acadia University, highlight the evolving nature of tick-borne threats. She notes that the black-legged tick, responsible for transmitting both Lyme disease and anaplasmosis, is becoming more effective at carrying multiple pathogens. This shift is attributed to several factors, including the reduction in winter severity, the growth of the deer population, and alterations in land use patterns that affect wildlife habitats. These changes create favorable conditions for ticks to thrive and expand their range. The data reveals a consistent rise in Lyme disease cases as well. In 2025, Nova Scotia reported 2,788 confirmed cases, marking an increase from 2,351 in 2024 and 2,057 in 2023. The provincial Department of Health emphasizes that the current environmental conditions, characterized by warmer temperatures and prolonged active seasons, are contributing to the proliferation of ticks and the subsequent spread of tick-borne diseases. This trend aligns with broader observations across Canada, where health officials have noted a steady increase in cases of various tick-related illnesses. Dr. Vett Lloyd, alongside health science reporter Jennifer Yang, addressed common queries regarding tick safety during a recent Q&A session. They explained that the current tick season is among the most severe in Canada, driven largely by the warming climate. Longer summers and milder winters provide ideal conditions for ticks to survive and reproduce. Additionally, migratory birds play a role in introducing ticks into new regions, with estimates suggesting millions of black-legged ticks are carried into Canada each year. These ticks can establish new populations once they detach from their avian hosts, leading to rapid population growth due to their high reproductive capacity. Prevention strategies emphasize early detection and prompt action. Individuals are advised to conduct regular tick checks after spending time outdoors, using tools like magnifying glasses or smartphone cameras to identify potential ticks. If a tick is discovered, immediate removal is recommended to minimize the risk of disease transmission. Public health experts stress that recognizing symptoms such as flu-like signs or characteristic rashes is crucial, though not all individuals will exhibit visible indicators of infection. Furthermore, researchers are monitoring emerging concerns associated with tick bites, including alpha-gal syndrome, a rare condition that can develop following certain tick bites and result in an allergic reaction to red meat. While currently uncommon, the awareness of such conditions underscores the importance of vigilance and proactive measures to mitigate the risks posed by tick-borne illnesses. As the situation evolves, continued research and public education will be essential in addressing the challenges presented by the rising prevalence of these diseases.
