In 2025, the Region of Waterloo witnessed an unprecedented surge in potential rabies exposures, with a staggering 1,642 cases reported to public health officials. This marks a significant peak in a five-year upward trend, starting from 1,209 cases in 2021. The region's public health authorities responded by conducting the highest number of rabies investigations ever, with a notable 18% of these cases requiring rabies post-exposure prophylaxis (rPEP) for 291 individuals. This figure represents a substantial increase from the 229 people who received rPEP in 2024. The complexity of these investigations has grown, reflecting the rising number of cases necessitating post-exposure prophylaxis. Despite this heightened exposure, it's reassuring to note that no human cases of rabies were reported between 2021 and 2025, and only five animals tested positive for the disease: four bats and one skunk. The report emphasizes the importance of pet vaccination and encourages residents to promptly report any animal bites or scratches. Public health staff will continue to advocate for these measures and provide necessary post-exposure prophylaxis when required. This situation underscores the critical role of public health initiatives in safeguarding communities against potential rabies outbreaks.
