The challenge is no longer limited to detecting spillover events, but requires continuous genomic surveillance to track an increasingly dynamic viral evolution.

From international flyways to the tire of a truck, H5N1 transmission is systemic and surveillance must match this complexity.

In the face of this complexity, responses must be integrated, ecological and structurally informed.

4/10 H5N1 has made "unprecedented leaps" to 50 mammal species - from rats to elephant seals to house cats.
The virus has infected over 1,000 dairy herds across 17 states, bringing it dangerously close to humans.
#H5N1 #DairyCattle
6/9 GLOBAL CONTEXT:
While U.S. dairy farms battle H5N1 in cattle (1,000+ herds infected), Asia continues seeing sporadic but deadly human cases.
The virus is active on multiple fronts globally - wild birds, poultry, mammals, and occasionally humans.
#GlobalSpread #DairyCattle #MultiSpecies
7/12 DAIRY CATTLE SHOCK: "No one expected the virus to hit U.S. dairy cows."
How it jumped from wild birds to farms remains mysterious, but genetic mixing in wild birds likely created the "new genotype" now infecting cattle.
Another milestone crossed.

6/20 Dairy cattle face mounting threats too.
Since March 2024, 31 Michigan herds across 13 counties confirmed infections.
Milk production drops dramatically, cows produce thick, discolored milk, and 1-2% die or exit herds permanently.

2/9 The findings come exactly one year after H5N1 avian flu was first confirmed in Texas dairy cattle.
Before that outbreak, cattle weren't typically considered natural hosts for influenza A viruses, making this research particularly significant.
#H5N1 #DairyCattle
2/7 Researchers traced the Ohio outbreak to the introduction of apparently healthy lactating cows from Texas, with decreased rumination & milk production beginning about 5 days before clinical diagnosis—suggesting a critical window when infections spread undetected.

600 dairy herds have been infected in California with bird flu. There are only 800 dairy herds in the entire United States. H5N1 is already everywhere. This is a pandemic. A lot of different species have have been infected. Polar bears to sea lions.
