A child in Canada died from rabies after waking to find a bat on his face, in a rare case that doctors say shows why possible exposure should be treated seriously even when no bite or scratch can be seen.
The 11-year-old boy was staying with his family at a cottage in northern Ontario in 2024 when he woke up with a bat resting on his nose and mouth. According to a report published in the Canadian Medical Association Journal, he swatted the animal away before his father caught it in a pot and released it outside.
His parents did not notice any wounds on his face and did not think the bat had been acting unusually. They therefore did not seek medical help at the time and did not consider rabies as a possible risk.
Nineteen days later, the boy developed tingling, numbness and swelling on the right side of his face. He was initially discharged from hospital with a presumed diagnosis of herpes gingivostomatitis, an infection that can cause painful mouth and gum symptoms. The earlier bat contact later prompted a doctor to ask the local public health authority whether rabies treatment should be given.
By the next morning, his condition had deteriorated and he was admitted to intensive care. Doctors reported that rabies was then strongly suspected. Brain imaging showed lesions affecting the brain stem and laboratory tests supported the diagnosis.
The medical team considered giving rabies antibodies directly into the brain, but the report said the invasive nature of the procedure and the lack of established evidence that it would work led the family and clinicians not to proceed with further treatment. The child later died.
Rabies is a viral infection that affects the brain and nervous system. It is usually passed to humans through the saliva of an infected animal, most often by a bite, but it can also enter through scratches, broken skin or the eyes, nose or mouth.
The doctors described the case as “exceedingly rare” in Canada. The journal report said only 28 human cases had been documented in the country since 1924, with the last confirmed case in Ontario dating back to 1967. Rare events can still carry serious consequences because rabies is almost always fatal once symptoms begin.
The report said bats are the main source of human rabies exposure in North America, although skunks, raccoons and foxes can also carry the virus. It noted that bat bites and scratches may be very small and easily missed, particularly if contact happens while a person is asleep or involves the face.
Doctors also warned that people should not rely on an animal’s behaviour to decide whether there is a risk. Rabid bats may appear during the day, lie on the ground, have trouble flying or allow people to approach them. However, the authors said the absence of these signs does not rule out infection.
The practical issue for families is that prevention depends on acting before illness develops. Rabies post-exposure prophylaxis, often called PEP, is a course of treatment given after a possible exposure. It can include wound cleaning, vaccine doses and, in some cases, rabies antibodies. The Canadian report said PEP is nearly always effective when given promptly after exposure.
Once symptoms start, however, there is no established cure. Rabies often has an incubation period of several weeks, although timing can vary. Early symptoms can be vague and may include unusual sensations near the exposure site, fever, headache or weakness before more severe neurological symptoms develop.
The case is relevant beyond Canada because bats are common in many countries and close contact can happen in homes, holiday accommodation, outbuildings or outdoor settings. Public health advice in many places is to seek urgent medical or public health assessment after a bat bite, scratch or possible saliva contact, especially if the person was asleep, is a child, or cannot reliably say whether contact occurred.
This does not mean most bat encounters lead to rabies. Human rabies remains very uncommon in countries with strong public health systems and access to preventive treatment. The concern is that the window for effective prevention is before symptoms appear, so a risk assessment needs to happen early.
The Canadian doctors said the boy’s death probably could have been prevented with greater awareness of how rabies can be transmitted and when treatment is needed. They concluded that early recognition of exposure and timely PEP remain the only effective means of preventing rabies after possible contact.
The current position is that the case remains an exceptional but important public health warning. Anyone who has had direct contact with a bat, particularly around the face or while asleep, should treat it as a matter for prompt medical assessment rather than waiting to see whether marks or symptoms appear.
