The bird flu virus was discovered in dairy herds from Michigan to Idaho, indicating that the disease has spread to new regions of the United States.
The US Department of Agriculture (USDA) reported last Friday that the National Veterinary Services Laboratory confirmed the presence of avian influenza in a flock in Michigan that recently received animals from Texas.
According to the USDA, as in previous cases, the strain of the virus found in Michigan appears to have been introduced by wild birds and transmission between cattle cannot be ruled out.
Initial tests found no changes in the virus that would make it more transmissible to humans. However, the agency says there is still no concern about the safety of commercial milk supplies.
There is concern that the flu may have already spread across borders. Florian Krammer, a professor in the microbiology department at the Icahn School of Medicine at Mount Sinai, said on Europe”.
On March 27, Mexico’s National Agricultural Food Health, Safety and Quality Service, known as Senasica, detected the highly pathogenic AH5N2 bird flu on a family farm in the state of Michoacan, according to a statement from the Ministry of Agriculture.
