An evaluation of tick and Lyme disease information on health unit websites in Ontario
Climate change has allowed for the expansion and intensification of blacklegged ticks; the vector of Lyme disease. Projections estimate that by the year 2049 all health units in Ontario will have suitable environmental conditions for the establishment of this vector. A review of website content from health units in Ontario was performed to assess the quality of tick and Lyme disease information provided to the public and health care providers. Websites were evaluated based on criteria such as the provision of Lyme disease information (i.e., transmission, symptoms, treatment, etc.), the inclusion of misleading or incorrect information, and visuals provided. The quality of textual and visual information varied substantially across the 35 health units analyzed. Eleven health units were found to provide misleading or incorrect information. Disparities were found between areas with current Lyme disease risk and those without. The majority of health units did not include satisfactory visual content pertaining to ticks. Given the expected expansion and intensification of blacklegged tick populations across the province, all health units must ensure the information communicated to the public about ticks and Lyme disease is of high-quality and consistent. We conclude with specific recommendations to improve the textual and visual content of websites.
