teen was suspected of being the first person to get the virus in Canada and was critically ill in hospital as of Tuesday. It wasn\u2019t known how they were exposed.<\/p>\n<p>Human-to-human transmission of H5N1 \u2014 a strain of highly pathogenic avian influenza \u2014 is rare with no evidence of sustained transmission, experts say. The majority of human cases in the United States and around the world have been due to contact with infected birds, farm animals or wildlife.<\/p>\n<p>But the more people become infected by animals, the more opportunities the virus has to mutate and spread between humans, said Angela Rasmussen, a virologist at the University of Saskatchewan\u2019s Vaccine and Infectious Disease Organization (VIDO).<\/p>\n<p>\u201cThe longer a virus is able to get evolutionary experience with a particular host species, it\u2019s going to continue to adapt to being in that host,\u201d Rasmussen said.<\/p>\n<p>\u201cOne of those adaptations would potentially be increased transmission and increased transmission efficiency.\u201d<\/p>\n<p>Rasmussen said the Canadian government should build a stockpile of H5N1 influenza vaccines like the United States rather than rely on agreements with manufacturers to supply them on demand.<\/p>\n<\/section>\n<div aria-labelledby=\"SaskatoonStarPhoenixAfternoonHeadlines1635249757609824491267314834997248\" data-account-id=\"b9d3df2fccd108b5eff3c44f573b2cd6\" data-aqa=\"widget-newsletter\" data-newsletter=\"single\" data-newsletter-component data-target-list=\"SP_HeadlineNews\" data-widget=\"newsletter\">\n<p>By signing up you consent to receive the above newsletter from Postmedia Network Inc.<\/p>\n<\/div>\n<section>\n<p>Article content<\/p>\n<\/section>\n<section>\n<p>Article content<\/p>\n<p>Dr. Fahad Razak, an internal medicine specialist at St. Michael\u2019s Hospital in Toronto, agreed, noting it would take three to six months to deploy an H5N1 vaccine under existing contracts.<\/p>\n<p>\u201cIn the event that you\u2019ve had to rapidly start to protect people, the ramp-up period could just be too slow,\u201d said Razak, who was scientific director of a provincial advisory table during the COVID-19 pandemic.<\/p>\n<p>The Public Health Agency of Canada said by email that it is not stockpiling H5N1 vaccines because \u201cthe shelf-life of the vaccines is only up to 2 years.\u201d<\/p>\n<p>Razak countered that Canada doesn\u2019t need vaccine doses for the whole country.<\/p>\n<p>Keeping enough H5N1 vaccines on hand to immunize people at high risk because they come in contact with potentially infected birds and animals, such as agricultural workers, could be \u201ca middle of the road approach,\u201d he said.<\/p>\n<p>Finland is already offering H5N1 vaccination \u201cto individuals who have a high occupational risk of being exposed to avian flu,\u201d said Dr. Matthew Miller, the director of the Michael G. DeGroote Institute for Infectious Disease Research at McMaster University in Hamilton.<\/p>\n<\/section>\n<section>\n<p>Article content<\/p>\n<p>Miller said offering the shot to dairy workers, poultry workers or those who work with potentially infected wildlife to reduce their risk of exposure would also reduce the risk of a pandemic.<\/p>\n<p>\u201cThis is something that\u2019s being talked about in jurisdictions all over the world,\u201d said Miller.<\/p>\n<p>When it comes to surveillance, PHAC said provincial and territorial public health agencies must report both \u201cconfirmed and probable\u201d H5N1 cases within 24 hours. It said the National Microbiology Lab in Winnipeg can rapidly test and detect human cases for jurisdictions unable to test locally<\/p>\n<p>The Canadian Food Inspection Agency has also been testing milk for signs of H5N1 in dairy cows. There has not yet been any indication of the virus in Canadian cows, but bird flu has plagued many herds in the United States.<\/p>\n<p>Razak also called for wastewater testing \u2014 used during the COVID-19 pandemic \u2014 to scale back up for bird flu.<\/p>\n<p>British Columbia is actively looking for H5N1 in its wastewater, but Ontario halted its provincial wastewater testing program earlier this year.<\/p>\n<p>PHAC does wastewater testing for seasonal flu in several cities and towns across the country, including Toronto. But it doesn\u2019t check specifically for H5N1 bird flu because it\u2019s \u201cnot possible to differentiate positive wastewater signals that are due to wildlife versus human or livestock sources,\u201d the agency told The Canadian Press in an email.<\/p>\n<\/section>\n<section>\n<p>Article content<\/p>\n<p>That makes\u201dit challenging to accurately interpret results to inform risk assessment and potential actions,\u201d it said.<\/p>\n<p>Still, wastewater testing can be set up in targeted locations where the majority of waste comes from humans, Razak said.<\/p>\n<section aria-labelledby=\"moreTopicLabel5675289946250923085973358813118464\" data-aqa=\"embed-more-topic\" data-carousel-component data-carousel-icon-button data-carousel-type=\"list\">\n<p>Recommended from Editorial<\/p>\n<ol data-carousel-slide-list tabindex=\"0\">\n<li data-evt-val=\"{\"control_fields\": {\"mparticle\": {\"keys\": {\"click_source_type\": \"click_source_type\", \"data_source\": \"data_source\", \"anchor_text\": \"anchor_text\", \"widget_title\": \"widget_title\", \"target_url\": \"target_url\", \"target_article_title\": \"target_article_title\", \"target_article_id\": \"target_article_id\", \"target_article_position\": \"target_article_position\", \"layout_section\": \"layout_section\"}, \"mp_event_type\": \"Navigation\", \"extra_keys\": [\"click_vertical_position_percentage\", \"click_vertical_position_pixels\"]}}, \"click_source_type\": \"widget-list\", \"data_source\": \"editorial\", \"anchor_text\": \"Young Innovators: U of S PhD student takes animal pathogen research international\", \"widget_title\": \"recommended-from-editorial\", \"target_url\": \"https:\/\/thestarphoenix.com\/news\/local-news\/young-innovators-u-of-s-phd-student-takes-animal-pathogen-research-international\", \"target_article_title\": \"Young Innovators: U of S PhD student takes animal pathogen research international\", \"target_article_id\": \"012719d0-07e4-447c-a0da-a152c77acc67\", \"target_article_position\": \"0\", \"layout_section\": \"recommended-from-editorial\"}\" data-carousel-item data-evt=\"click\" data-evt-typ=\"click\"><a href=\"https:\/\/thestarphoenix.com\/news\/local-news\/young-innovators-u-of-s-phd-student-takes-animal-pathogen-research-international\"> <picture><img decoding=\"async\" alt=\"Kezia Fourie, a fourth-year PhD student enrolled in the Department of Veterinary Microbiology at the U of S's Western College of Veterinary Medicine (WCVM), is investigating Lawsonia intracellularis, a bacteria found in pig barns around the globe that mainly infects the intestines of pigs, but also has effects on many other species.
