Rabies Updates

In 2021, two bats have tested positive for rabies within the Middlesex-London area. One bat was from the City of London and the other was from Glencoe. Low numbers of positive bats have been seen over the past few years.


Why is rabies a concern?

Humans and other animals can become infected during a bite or scratch from a rabid animal (rabies infected).1 This can happen if the rabid animal’s saliva or the virus comes in contact with an open cut or the moist tissues of the mouth, nose or eyes.1 Once symptoms appear, rabies is almost always fatal in animals and humans.2

How is rabies transmitted?

In Canada, rabies is transmitted by wildlife. Foxes, skunks, and bats are the main carriers of the disease.2
