The HPAI virus continues to spread and is severely impacting commercial farms in the US. From November 1st to December 8th, more than 7 million commercial laying hens, along with over 2 million commercial turkeys, were culled. The current policy in the USA still prohibits the use of vaccines as a means of controlling the disease. It appears that this policy is contributing to the ongoing spread of the virus in commercial farms.Dealing with such large farms cannot result in the rapid destruction of flocks. Consequently, the virus continues to spread in the environment, affecting more commercial flocks. Wild birds are becoming infected, perpetuating the spread of the virus and contributing to its evolution. There is an escalating risk of the virus adapting further to mammals. The widespread mortality of seals and sea lions on the coasts of South America, and more recently in Brazil, serves as evidence of this concerning trend.
