They show "empirical genetic evidence supporting the windborne transmission of the H5N1 HPAI virus over a distance of 8 km, [...] combined with a detailed epizootiological investigation and strong correlation with weather conditions, confirms that wind can transport infectious virus particles over substantial distances and, thereby, facilitate the spread of HPAI between poultry farms."

To reiterate: ⚠️ "The veterinarians suggest the only possibility left is that the VIRUS WAS CARRIED ALOFT BY THE WIND and wafted into the barn, settling on the captive birds" and infecting them! ⚠️

Is H5N1 definitely airborne? Convincing proof would have to have unbelievable controls!
"veterinarians were conducting research on a highly secure chicken research farm—the birds there were not allowed out of their cages or barns. The water came from a secure well and was filtered to remove pathogens. The barns have large fans that create a one-way airflow, and the entire facility is surrounded by a highly secure fence.
Also, no employees came into contact with any other birds when not on duty. Still, the farm experienced an infection. The veterinarians suggest the only possibility left is that the virus was carried aloft by the wind and wafted into the barn, settling on the captive birds."
[1]Yup that would do it!

Possible evidence of windborne H5N1 viral infections in chickens
A team of government veterinarians with the State Veterinary Institute Prague in the Czech Republic has found possible evidence of windborne H5N1 infections in chickens.Bob Yirka (Phys.org)
Could H5N1 be spread for multiple kilometres by air?
"some reports have proposed that windborne spread plays a significant role in IAV [Influenza A Virus] transmission over longer distances under suitable weather conditions.
➡️ In studies of the severe H7N7 HPAI [Highly Pathogenic Avian Influenza] outbreak in the Netherlands in 2003, one study claimed that wind spread accounted for 18% and another 24% of transmission events up to 25 km.
➡️ Similarly, during the 2007 equine H3N8 influenza outbreak in Australia, 81% of infections within a cluster of 437 horse farms were attributed to windborne spread over a distance of 1-2 km.
➡️ Around the same time, the serological screening of turkeys in Minnesota in 2007-08 revealed that turkey premises within a 1.9 km radius of swine farms were most likely to test seropositive for H3N2 and H1N1 IAVs, thereby suggesting windborne transmission.
➡️ And during the 2014-15 multistate H5N2 HPAI outbreak in the USA, it was estimated that up to 39% of farms in Iowa alone could have experienced windborne infection within a radius of 8.5 km"
