Bird Flu: A Strange Discovery in Arizona and Its Consequences

What happened?

On February 17, the Arizona Department of Agriculture (AZDA) and the United States Department of Agriculture (USDA) confirmed the presence of the H5N1 virus in MILK from cattle . The discovery of the virus was part of a national monitoring strategy launched in January. Importantly, the cows from which the milk was obtained did not show symptoms of the disease, which may indicate that the virus is not present in this animal population.

Quarantine and precautions

Due to the detection of the virus, a quarantine was established on the farm . This is standard practice in such cases, aimed at preventing further spread of the virus. HEALTH experts reassure the public, emphasizing that this genotype of the virus does not show signs typical for human infection. This means that the risk of transmission of the virus from animals to people in this case is extremely low. Health

risk

Although there is no immediate threat to people, cases of avian influenza in other regions of the United States are causing concern. In recent months, the H5N1 virus has caused numerous deaths of birds, including cases in zoos. Two people who had contact with infected poultry in Pinal County also tested positive. These events highlight the need for ongoing monitoring and control of the virus's spread.

Research and Monitoring

: To prevent further spread of avian influenza in the United States, the All-Russian Research Institute of Animal Health (ARRIAH) began screening cattle for the virus in 2024. No positive cases have been identified to date, and monitoring efforts are ongoing. The institute has also developed interim guidance for monitoring avian influenza in atypical animal species, expanding opportunities for early detection and outbreak prevention.

The avian influenza situation in Arizona and other states underscores the importance of vigilance and preparedness to respond to potential threats. While current data indicate a low risk to human health, it is important to continue research and monitoring to ensure the safety of both animals and people. The public should remain informed and follow expert advice to minimize risks and prevent potential disease outbreaks.
