In a concerning health alert for residents of British Columbia, officials are warning pet owners to steer their animals clear of ponds, as they investigate how a teenager recently contracted the potentially deadly H5N1 avian influenza virus.

During a briefing on Tuesday, provincial health officer Dr. Bonnie Henry revealed that genome sequencing revealed the adolescent was infected with the same strain wreaking havoc among wild birds and poultry farms across the province. The closest match identified so far came from two geese in the Fraser Valley, which tested positive for the virus last October.

Currently hospitalized in critical condition at BC Children’s Hospital, the teenager's case remains a baffling mystery for health officials, as an extensive investigation has yet to identify the source of infection or any additional cases linked to it.

Dr. Henry cautioned that avian influenza can persist in bodies of water frequented by wild birds, especially during the migration season, raising significant concerns. “We know that ponds that have ducks and geese in them right now can harbor the virus, as their droppings contaminate the water,” she explained. This highlights the need for pet owners to keep their animals away from both sick and deceased birds, as well as from stagnant water.

Adding to the concern, Dr. Henry advised families against engaging with poultry at petting zoos, particularly if children are involved. “Some of these farm visits where children handle chickens should be avoided at this time,” she warned, emphasizing the risks associated with direct contact.

For those who may come into contact with bird droppings, Dr. Henry stressed the importance of thorough handwashing to limit exposure. Additionally, she encouraged residents to get their flu shots this year, citing research suggesting that the vaccine could offer partial protection against avian influenza.

While human infections with avian influenza remain rare, they typically occur following close contact with infected birds or environments laden with contaminated materials. As authorities continue their investigation and monitoring efforts, the community is urged to stay informed and exercise caution during this critical time.
