Avian Influenza Outbreak in Cows

CDC Reports on H5N1 Prevalence in Milk

April 19, 2024

Widespread Outbreak

The Centers for Disease Control and Prevention (CDC) continues to monitor the ongoing outbreak of avian influenza, commonly known as bird flu, with a particular focus on its presence in cows. Recent tests have revealed that the H5N1 strain of the virus, known to cause severe respiratory disease in birds, is also widespread in the U.S. cattle population.

Transmission and Symptoms

H5N1 is a highly contagious virus that can spread rapidly through contact with infected animals, bodily fluids, or contaminated surfaces. In cows, the virus can cause a range of symptoms, including respiratory distress, fever, lethargy, and decreased milk production. In some cases, it can also lead to neurological problems, including blindness and death.

Public Health Concerns

While the risk to human health from the current H5N1 outbreak is considered low, the CDC is urging the public to take precautions. Consumption of raw milk from infected cows should be avoided, as it can transmit the virus to humans. Proper hygiene practices, such as handwashing and disinfection of surfaces, are also recommended to prevent the spread of infection.

Ongoing Research

Researchers are actively studying the H5N1 outbreak in cows to better understand its transmission, potential risks, and possible mitigation strategies. The CDC is collaborating with state and local health departments to monitor the situation and provide updates as they become available.
