Bird Flu • Avian Influenza A(H5N2)

What is Avian Influenza (Bird Flu)?

Avian influenza, often called bird flu, is a respiratory illness that primarily infects birds. Different strains exist, with some causing mild illness and others highly contagious and deadly in birds. Outbreaks of these virulent strains can devastate poultry farms, leading to significant economic losses.

First Human Death from H5N2

In a concerning development, the World Health Organization (WHO) confirmed the first documented human death from the H5N2 strain of avian influenza. A 59-year-old resident of Mexico with underlying health conditions fell ill in April and later died from complications. This case highlights the potential of certain bird flu strains to jump to humans, although the WHO currently assesses the risk to the general public from H5N2 to be low.

News and Concerns

This first human fatality from H5N2 raises concerns about the potential for bird flu to spread to humans. The virus has been spreading among animals in various countries since 2020, with the H5N1 strain infecting dairy cows in the United States and causing mild illness in three farmworkers. While the current risk appears low, continued monitoring and research are crucial to understand the evolving situation.

Protecting Poultry Farms

Biosecurity measures are essential for preventing bird flu outbreaks in poultry farms. These measures include:

  • Controlling access: Limit entry to farms to authorized personnel only.

  • Disinfectant foot baths: Implement foot baths with disinfectant solution to prevent the spread of the virus on footwear.

  • Isolating sick birds: Immediately isolate and report any birds showing signs of illness, such as coughing, sneezing, or sudden death.

Protecting Yourself

While the current risk to humans appears low, practicing good hygiene can help minimize the chance of contracting bird flu. Here's what you can do:

  • Wash hands thoroughly: Wash your hands with soap and water for at least 20 seconds after contact with poultry or birds, especially before eating or drinking.

  • Avoid sick or dead birds: Don't touch sick or dead birds, and avoid areas where they have been present.

  • Cook poultry thoroughly: Ensure poultry is cooked to an internal temperature of 165°F (74°C) to kill any potential viruses.

Staying Informed

Staying informed about avian influenza developments is crucial. Reliable sources include the World Health Organization (WHO) and your local health department websites. By following these recommendations, we can protect ourselves, the poultry industry, and help prevent the spread of avian influenza.
