An 11-year-old boy in Ontario, Canada, has died after being bitten by a rabid bat that was resting on his face as he slept. The boy had no obvious bite or scratch marks and didn’t show symptoms for the first 19 days after the incident, his doctors report.
While on vacation with his parents at a cottage in northern Ontario in 2024, the boy was woken up in the night by a bat on his nose and mouth, according to a report published in the Canadian Medical Association Journal on June 29. His father caught the bat in a cooking pot and released it outside, and because the child had no visible injuries and the bat did not seem to be particularly aggressive, his parents decided not to seek a medical assessment, the report noted.
A few weeks later, the child began to experience tingling, numbness and swelling on the right side of his face. When he was examined at his local hospital his vital signs appeared to be normal, aside from an elevated heart rate and white blood cell count.
The next day, the boy’s symptoms worsened: he lost feeling in the right side of his face and his speech was beginning to slur. While waiting in hospital, he developed a fever, confusion, hallucinations and difficulty swallowing, followed by excessive production of saliva.
After four days in intensive care at McMaster Children’s Hospital in Hamilton, Ontario, the child tested positive for rabies, and after five days his brain stem reflexes were absent, indicating a total loss of brain stem function. Seventeen days after admission, following a consultation between his family and medical experts, he was taken off life support and died.
Rabies is a viral disease that primarily affects the central nervous system, according to the CDC. It is mainly spread through bites and scratches from infected animals, with bats accounting for the majority of cases in North America, according to the boy’s doctors.
“Bats pose a particular risk because bites or scratches may be small and are easily overlooked, and patients may not recollect or recognize a bat exposure,” the medical team wrote in their report.
According to a report in the Journal of Virology in 2013, silver-haired bats (Lasionycteris noctivagans), are responsible for the majority of rabies cases in Canada. Skunks, foxes and raccoons also often carry the disease.
The rabies virus must travel to the brain before symptoms can occur, but once a patient develops symptoms the infection is almost 100% fatal, with most deaths occurring within one to two weeks of symptom development. However, prompt treatment after exposure — including wound cleaning, antibody administration and a series of vaccines — is nearly always effective at preventing the disease, according to the CDC.
Rabies in humans is very rare in North America, with fewer than 10 deaths reported in the U.S. every year, according to the CDC. In Canada, only 28 human fatalities have been reported since 1924, according to the Canadian Veterinary Medical Association. Even so, the boy’s doctors have emphasized the importance of prompt medical attention following exposure to bats and other animals that could carry the disease.
“Early recognition of exposure and timely PEP [postexposure prophylaxis] remain the only effective means of rabies prevention,” they wrote. “Any direct human contact with a bat, even in the absence of a visible bite or scratch, is an indication for PEP.”
They added that rabid bats do not always display the classic symptoms commonly associated with rabies, such as aggressive behavior and frothing at the mouth. “Any direct human contact with [a] bat is considered high risk,” they added.
