A new type of bird flu has been found in dairy cows in Nevada. The virus has jumped from birds to cows and raised some questions. The strain found in cows is different from what has been seen before. Scientists are concerned about how the virus could affect humans. The bird flu variant, called D1.1 genotype, had been in wild birds and led to severe illness in some people. It is the first time it has been found in cattle. The virus is believed to have spread from birds to cattle in late 2023 in Texas. This new variant in dairy cows could make it harder to eliminate the virus. Scientists are unsure how long the virus has been in cattle and how widespread it may be. This new strain raises new questions about the outbreak in cattle and its impact on humans. Vaccines may need to be adjusted to combat this new strain. The virus may not be much different in cows, but its impact on humans could be severe. Some cases have led to critical conditions and even death. Scientists are studying how the virus evolves and its effect on humans. Because so much attention has been on another variant, it may take time to fully understand the risks of this new strain. Researchers will continue to study the virus to protect both cattle and humans. In conclusion, a new type of bird flu has been found in dairy cows in Nevada, and scientists are working to understand its impact on both animals and humans.
