Published 4 months ago
Description
Welcome to H5N1 Global Scan: Avian Flu Worldwide. Im Dan from Quiet Please, bringing you the latest on this spreading threat.
H5N1 avian flu, clade 2.3.4.4b, has exploded globally since 2022, hitting birds, mammals, and rarely humans. PAHO reports 5063 outbreaks in 19 Americas countries through week 41 of 2025, up from 4713 earlier. Worldwide, WHO tallies 990 human cases since 2003 with 475 deaths, 48 percent fatality. Recent surges: 954 animal outbreaks in 38 countries since late September per FAO.
Continental breakdown: In the Americas, US leads with 2912 poultry outbreaks and 976 dairy herds hit by early 2025, plus 147 more in birds and mammals. Canada reports seven poultry cases; Argentina, Peru, others follow. Europe sees ongoing wild bird die-offs via ECDC. Asia reports 19 human cases June to September 2025 in Bangladesh, Cambodia, China, India, mostly poultry-linked. Africa and Middle East face HPAI in multiple subtypes per FAO. North America now detects H5N5 in wild birds and one US human case November 2025, first globally.
Major research: WOAH tracks mammal spillovers in 19 countries across three continents. CDC notes 71 US human cases since 2024, 41 from dairy cattle, no human-to-human spread. ECDC emphasizes rare human infections despite animal circulation.
WHO urges One Health surveillance, intersectoral response, and risk communication. FAO monitors zoonotic potential, calling for coordinated reporting. Global efforts include WOAHs outbreak portal and PAHOs Americas updates for prevention.
Cross-border issues: Migratory birds spread via flyways, as PAHO maps show. Trade impacts poultry exports; US culls millions, disrupting markets.
Vaccine status: Poultry vaccines used variably; human trials advance but no approved global shot yet. US focuses targeted surveillance of 15200 exposed workers.
National approaches differ: US emphasizes dairy monitoring and farm biosecurity, reporting 70 targeted human cases. Americas varyculling in Argentina, surveillance in Canada. Asia relies poultry vaccination; Europe wild bird focus without mass culls.
