An 11-year-old Canadian boy died of rabies 17 days after a bat landed on his face while he slept at an Ontario cottage, according to a case report published June 29 in the Canadian Medical Association Journal (CMAJ). The child, whose family did not seek immediate medical care because there were no visible bite marks, represents the first case of rabies acquired within Ontario since 1967.
Why small bat encounters require immediate medical attention
Medical experts emphasize that any direct contact with a bat warrants a discussion with public health authorities, even in the absence of a visible wound. According to doctors from McMaster Children’s Hospital and the University of Manitoba, bat bites can be too small to notice. While rabid bats may display atypical behavior—such as being active during the day or showing an inability to fly—the absence of these signs does not rule out the presence of the virus.
Rabies is nearly always fatal once clinical symptoms appear. Only 34 survivors have been documented globally, most of whom suffered significant long-term neurological damage.
The progression of symptoms and diagnostic challenges
The boy’s symptoms began seven days before his initial hospital admission, manifesting as numbness and tingling on the right side of his face. He was initially diagnosed with Bell’s palsy at an urgent care clinic and prescribed antivirals, but his condition worsened, leading to facial swelling and an inability to swallow. Upon returning to the emergency department, he presented with slurred speech and worsening neurological deficits.
According to the CMAJ report, doctors suspected rabies only after the family mentioned the bat encounter. Testing of the boy’s saliva confirmed the diagnosis four days after his admission to the pediatric intensive care unit. Despite the medical team considering experimental interventions, including antibody infusions and gene therapy, these were not pursued due to limited availability, lack of proven effectiveness and the child’s rapid clinical decline.
How rabies is prevented
Preventive treatment, which consists of a post-exposure vaccine series and, in specific cases, immune globulin, is highly effective if administered before the virus reaches the brain. Once neurological symptoms emerge, there is no proven cure. Since 1924, only 28 human rabies cases have been recorded in Canada. The rarity of the disease often complicates early diagnosis, as seen in this case where initial symptoms mimicked a common herpes-related infection.
If you or a family member has direct contact with a bat, contact local public health officials immediately to discuss post-exposure prophylaxis. Never assume a lack of visible injury means you are safe.
Frequently Asked Questions
What are the early signs of rabies?
According to the Mayo Clinic, initial rabies symptoms often mimic the flu. These can include fever, headache, nausea, vomiting, agitation, anxiety, and confusion.
Can rabies be treated after symptoms start?
No. Once the virus reaches the brain and clinical symptoms appear, the condition is almost always fatal. Treatment is only effective when administered as a preventive measure after exposure but before symptoms develop.
Why didn’t the family seek help sooner?
The family did not seek medical attention because the bat didn’t appear to be acting strangely and there were no visible bite marks or scratches on the boy’s skin.
