Fatal Rabies Case in Ontario After Bat Encounter
An 11-year-old boy in Ontario, Canada, died from rabies 19 days after waking up with a bat lying over his nose and mouth. The child contracted the deadly virus despite having no apparent bite or scratch marks from the incident, according to a report published in the Canadian Medical Association Journal (CMAJ). This marks the first fatal case of rabies in Ontario in more than 50 years.
Symptoms and Medical Response
Nineteen days after the bat encounter, the boy began presenting symptoms consistent with rabies, including vomiting, facial 'pins and needles,' and numbness. He visited the emergency department, where he received supportive care. There is no cure once symptoms of the virus develop. The parents, who have not been named, agreed to share their son's story to raise awareness about the disease.
Expert Guidance on Prevention
Dr. Brian Hummel, a paediatric infectious disease specialist at McMaster Children's Hospital and McMaster University, co-authored the report. He emphasized that any direct human contact with a bat—even without a visible bite or scratch—is an indication for post-exposure prophylaxis (PEP). PEP involves a series of rabies vaccines and human rabies immune globulin injections and is highly effective if administered promptly before symptoms develop.
'Any direct human contact with a bat – even in the absence of a visible bite or scratch – is an indication for PEP and should be discussed with public health authorities,' Dr. Hummel said. 'This is especially important to consider as we approach the summer months, when human–bat encounters are at their peak.'
Rabies Risks and Recommendations
Bats are the most common carriers of rabies in North America, but the disease can also be transmitted by raccoons, skunks, and foxes. Bats pose a heightened risk because their scratches or bites can be small and difficult to detect. Dr. Hummel added, 'Bats may or may not show classic signs of rabies; hence, any direct human contact with a bat is considered high risk.'
In the case of possible rabies virus exposure, public health authorities should be notified and PEP should be started in consultation. 'Rabies is almost always fatal, with no established efficacious therapies, making prevention crucial,' Dr. Hummel noted. 'Rabies PEP is highly effective if administered promptly, in consultation with public health authorities, after any direct human contact with a bat, even in the absence of visible lesions. In people with neurological symptoms that may be compatible with rabies, clinicians should ask about exposure to potentially rabid animals.'
The report aims to provide critical guidance to help prevent future rabies deaths. Anyone who may have had contact with a wild animal that could potentially have rabies should seek medical attention promptly.
