2 years ago a boy died of rabies from a bat. Doctors are reminding the public to be aware

Doctors ar urging people to seek medical attending if they feature any middleman with bats to forestall potential rabies infection.

In Monday's issue of the Canadian Medical Association Journal, infectious disease physicians described the case of a child who died of rabies almost two years ago.

"It was important to us and to the family to take the opportunity to find learning experiences and lessons that we could take from his case to try and help spread awareness and understanding of rabies infection and risks," said Dr. Brian Hummel, the case report's senior author and a pediatric infectious disease physician at McMaster Children's Hospital in Hamilton.

The 11-year-old boy was at a cottage in northern Ontario in the summer of 2024 and was awoken by a bat lying on his nose and mouth, the case report said.

He swatted the bat away and his father caught it in a pot and released it outside.

The parents didn't see any scratches or bites on their son's face and didn't think the bat had been behaving oddly so they didn't think of rabies or take him to a doctor at that time.

Almost three weeks later, the boy developed tingling, numbness and swelling on the right side of his face. His neurological condition deteriorated in the following days, following trips to an urgent care clinic and emergency department, where he was eventually taken off life support and "died peacefully with his family at his bedside," the case report said.

Once symptoms of rabies start, there is no treatment or cure, Hummel said.

But the virus has a relatively long incubation period — usually weeks — before symptoms of illness start to show.

That means that in the days after exposure, a series of vaccines and a dose of antibodies can stop the infection.

"If you get symptomatic rabies infection, it is near universally fatal. But if you get the prevention before symptoms develop, it is near universally successful," Hummel said.

The rabies virus infects the nerves around the site where it entered the body and then makes its way into the spinal cord and brain, ultimately leading to death.

It's "an extraordinarily rare infection" for humans in Canada, with only 28 cases reported since 1924, he said.

The most recent rabies case before the 11-year-old boy was a man who died after exposure to a bat in British Columbia in 2019. There hadn't been a case reported in Ontario since 1967.

When humans do get exposed in Canada, it's usually through contact with a bat, Hummel said, although rabies can also be carried by skunks, raccoons and foxes. But bats are the primary concern, so any physical contact with them is considered high risk.

Bats have tiny teeth, so people can be bitten and not even realize it. Even without a bite or scratch, a bat's saliva can get on someone's skin and find its way into a cut or into the eyes, nose or mouth.

"Any time a bat has touched the human skin, that would be a reason to go and see your health care provider right away," Hummel said.

Primary-care providers often work with public health to determine if post-exposure prophylaxis — the series of vaccines and the antibody injection — is warranted.

The first rabies vaccine shot is given immediately, followed by shots on days three, seven and 14.

Vaccination helps the body mount an immune response to the rabies virus, Hummel said.

But it takes time for that response to happen, so the patient also gets an injection of immunoglobulin, a ready-made antibody that starts fighting the virus right away.

Side effects of the vaccine are usually mild and temporary. They can include fever, chills, sweats and feeling unwell, he said.

Like any vaccine, there is a very rare risk of anaphylaxis, which is why patients have a short waiting period before they leave their health-care provider after the shot.

"Given the near certainty of death with rabies infection, the benefits almost always outweigh the risks," Hummel said.
