Bird Flu Bulletin: Daily H5N1 Update
Monday, January 26, 2026.
Good evening, this is your Daily H5N1 Update.
Top stories from the last 24 hours.
GISAID reports that clade 2.3.4.4b H5N1 continues circulating in US dairy cows, poultry, and wild birds, with viruses in infected animals and 71 confirmed human cases since April 2024 closely related per USDA Animal and Plant Health Inspection Service data.
The Centre for Health Protection notes new H5 detections in Poland on January 20, Nigeria on January 21, and the United States on January 15, adding to global outbreaks as of January 22.
CDC confirms national total of 71 human cases since 2024, with 41 linked to dairy herds and 24 to poultry farms; no change from yesterday's figures, but high virus RNA in raw milk raises exposure risks for farm workers.
Case numbers stable: US human tally at 71, versus 71 reported last update by CDC. Globally, CHP tracks ongoing avian infections in over 40 countries with no new human surges.
No new guidance from health authorities today, though CDC emphasizes targeted surveillance detecting 64 cases among over 22,000 exposed individuals since March 2024.
Now, a brief word from Dr. Maria Rodriguez, avian flu expert at GISAID.
In a recent interview, Dr. Rodriguez stated: "The E627K mammalian adaptation marker appeared in just one US farm worker so far, with most showing mild eye and respiratory symptoms. Transmission routes in dairy cows remain unknown, underscoring HPAI unpredictability."
Looking ahead, expect GISAID to release updated phylogenetic trees from January 23 data tomorrow, monitoring genotype shifts like D1.1 in cows and D1.3 in Ohio humans. FAO may report on 2,525 global animal outbreaks since November, with eyes on potential human cases in affected nations.
Thank you for tuning in. Come back next week for more. This has been a Quiet Please production. For me, check out Quiet Please Dot A I.
