First Canadian human H5N1 infection (?) https://afludiary.blogspot.com/2024/11/canada-bc-govt-announces-presumptive.html or https://afludiary.blogspot.com/2024/11/canada-bc-govt-announces-presumptive.html ;
Earlier today I blogged on the recent uptick in H5N1 outbreaks in poultry in British Columbia (see Canada: B.C. Reports 10 More Poultry Farm Outbreaks Of HPAI H5), and its growing prevalence in the environment. - This evening (h/t Treyfish on FluTrackers) the British Columbia Government has announced a presumptive positive H5 case in a teenager, hospitalized at B.C. Children's Hospital. Details are scant at this time - and there is no mention of contact with poultry, or the patient's condition - in this initial news release. Hopefully we'll learn more tomorrow. - The individual is a teenager from the Fraser Health region who is receiving care at BC Children’s Hospital. A public-health investigation has been initiated to determine the source of exposure and identify any contacts. - Public health is following up with contacts who may have been exposed in order to assess for symptoms and provide guidance on testing and prevention measures. There have been no further cases identified at this time. The source of exposure is very likely to be an animal or bird, and is being investigated by B.C.’s chief veterinarian and public health teams. https://flutrackers.com/forum/forum/canada/h5n1-tracking-ag/1000092-canada-british-columbia-health-statement-first-presumptive-positive-case-of-h5-avian-influenza-detected-in-b-c-confirming-test-pending-november-9-2024?view=stream or https://flutrackers.com/forum/forum/canada/h5n1-tracking-ag/1000092-canada-british-columbia-health-statement-first-presumptive-positive-case-of-h5-avian-influenza-detected-in-b-c-confirming-test-pending-november-9-2024?view=stream ; Raj Rajnarayanan @RajlabN · 27m #H5N1 #AvianInfluenza updates The recent #H5N1 human case reported from British Columbia, Canada is likely to be the same type as the one circulating in Washington, USA (and not the Dairy Cattle linked B3.13) https://x.com/RajlabN/status/1855105360136171955… DJ, So very likely poultry-to-human... 49m H5N1 #AvianInfluenza updates Quick analysis of the recently uploaded sequences to @gisaid from #BritishColumbia Canada [Cackling Goose, Canada Goose, Red tailed Hawk, Green Winged Teal] HA mutations: V11I, T52A, K341R, N491D Ref: HA A/Astrakhan/3212/2020 1/n x.com/RajlabN/status… DJ...if it turns out the Canada teenager did infect others the H5N1-virus "did get better" in spreading from mammal-to-mammal (and so H2H/Human-to-human)... Canada case also in https://flutrackers.com/forum/forum/flutrackers-high-pathogenic-h5n1-h1n08-h5n8-h5n6-h5n3-tracking-outbreaks-spread/749462-flutrackers-2016-global-h5n1-human-cases-list or https://flutrackers.com/forum/forum/flutrackers-high-pathogenic-h5n1-h1n08-h5n8-h5n6-h5n3-tracking-outbreaks-spread/749462-flutrackers-2016-global-h5n1-human-cases-list .... DJ-Mexico must have human cases of (cattle/raw milk consumption) linked cases of H5N1 (in farm workers send home frome the uS after getting ill ?) Start of flu-season is increasing further risk of dangerous types of flu...At least two pigs also tested positive for H5N1...Pigs can catch all four types of (known) flu (A,B,C, and D) -humans so far only A and B-type of flu...H5N1 may spread WITHOUT !!! symptoms in pigs...so very likely more H5N1-infections in pigs...The two detected cases were from a mixed farm with also cattle and/or poultry-infecting the pigs...
