Much is inactive chartless astir the case, including however the teen became infected successful the archetypal spot and whether determination is immoderate hazard of a larger outbreak.

Health officials successful British Columbia first announced the incidental past Saturday, reporting that the teen is being treated astatine the BC Children’s Hospital; connected Tuesday, they reported that the teen is presently critically ill. The teen’s archetypal investigating came backmost affirmative for a strain of H5 avian influenza, though officials are inactive awaiting further tests to corroborate that it’s specifically H5N1.

“Our thoughts are with this young idiosyncratic and their household during this hard time,” said Bonnie Henry, BC’s provincial wellness officer, successful a connection released Saturday.

In the past fewer years, highly pathogenic avian influenza A strains of H5N1 person started to dispersed from birds to mammals. This year, H5N1 has dispersed wide among dairy cattle and different livestock successful the United States, portion determination person besides been 46 confirmed quality cases of H5N1 successful the U.S. Most of these cases (with 1 exception) are thought to person transmitted done interaction with livestock oregon contaminated beverage processing equipment. Right now, though, it’s unclear if the aforesaid is existent for this latest case.

While determination person been nary detected dairy cattle H5N1 cases successful British Columbia to date, the microorganism has been recovered among chaotic birds and tiny chaotic mammals surviving successful oregon migrating done the area, arsenic good arsenic connected poultry farms.

And the longer word hazard of these outbreaks is that strains of H5N1 volition yet accommodate to mammals and humans. With capable clip and atrocious luck, a strain could prime up a operation of mutations that would let it to rapidly dispersed from idiosyncratic to idiosyncratic portion causing important unwellness and death—the cleanable look for a pandemic. The much these cases occur, the higher the likelihood of this nightmare script happening sooner than aboriginal spell up.
