**Avian Influenza: What You Need to Know** **January 20, 2020** Avian influenza, also known as bird flu, is a disease caused by infection with avian influenza virus Type A. It primarily affects wild water birds, but can also infect domestic poultry and humans. **Who is at risk for avian influenza?** People who work with poultry or come into contact with infected birds are at highest risk for infection. Transmission to humans occurs through contact with infected bodily fluids or contaminated surfaces. **Symptoms of H5N1 avian influenza in humans:** * Fever * Cough * Sore throat * Muscle aches * Fatigue * Difficulty breathing **Is it safe to eat chicken, poultry products, and other meats?** Yes, it is safe to consume cooked poultry and poultry products. The virus is killed by heat when cooked to an internal temperature of 165 degrees Fahrenheit. **How to protect yourself from avian influenza:** * Avoid contact with sick or dead birds. * Wear gloves and a mask when handling birds or their feathers. * Wash your hands thoroughly with soap and water after handling birds or their products. * Cook poultry and poultry products thoroughly to kill the virus. * Avoid raw or undercooked poultry and poultry products. * Report any sick or dead birds to your local veterinary authorities. **Additional Resources:** * [Centers for Disease Control and Prevention (CDC): Avian Influenza](https://www.cdc.gov/flu/avianflu/avian-flu-and-you.htm) * [World Health Organization (WHO): Avian Influenza](https://www.who.int/en/health-topics/avian-influenza)
**Different Types of Avian Influenza: Understanding the Threat** **Introduction** Avian influenza (AI), also known as bird flu, is a highly infectious viral disease that affects birds. It is caused by type A influenza viruses, which are divided into different subtypes based on their genetic makeup. **Subtypes of Avian Influenza** AI type A viruses are divided into 18 hemagglutinin (HA) and 11 neuraminidase (NA) subtypes. The combination of these subtypes determines the specificity with which the virus binds to and enters host cells. The most common subtypes associated with avian influenza in poultry are H5, H7, and H9. **Low Pathogenic Avian Influenza (LPAI)** LPAI is caused by viruses that cause mild or no clinical signs in infected birds. These viruses circulate widely in poultry populations and can be transmitted through contact with infected birds, their secretions, or contaminated materials. LPAI viruses typically do not pose a significant risk to humans unless they mutate into a more virulent form. **Highly Pathogenic Avian Influenza (HPAI)** HPAI is caused by viruses that cause severe illness and high mortality in infected birds. These viruses can spread rapidly through poultry flocks and can have devastating economic consequences. HPAI viruses can also infect humans and other species, posing a significant public health risk. **Importance of Understanding the Different Types of AI** Understanding the different types of AI is crucial for several reasons: * **Monitoring and surveillance:** Knowing the specific subtypes of AI viruses circulating in poultry populations helps veterinary authorities monitor and control the spread of the disease. * **Vaccination strategies:** Developing effective vaccines requires an understanding of the genetic diversity of AI viruses. * **Public health protection:** Identifying the subtypes of AI viruses that pose a risk to humans allows public health officials to take appropriate preventive measures. **Conclusion** Avian influenza is a complex and evolving disease. Understanding the different types of AI viruses, their characteristics, and transmission patterns is essential for controlling the spread of the disease, protecting poultry populations, and safeguarding public health.
**Avian Influenza Spreads to Wild Mammals Amidst New Bird Flu Strain** Avian influenza, commonly known as bird flu, is no longer confined to the bird population. Wild aquatic birds, including gulls and terns, are known to carry the influenza Type A virus, which causes avian influenza. However, a recent development has raised concerns as the virus is now affecting wild mammals as well. Experts are closely monitoring a new strain of bird flu that has been spreading rapidly among migratory birds, especially waterfowl. These birds serve as natural reservoirs of the avian influenza virus, and they can carry the virus without exhibiting any symptoms. The virus has now jumped the species barrier and is infecting wild mammals, including foxes, seals, and bears. While the transmission from birds to mammals is not a common occurrence, it highlights the adaptability and potential threat of the virus. The Animal and Plant Health Inspection Service (APHIS) has issued a warning that this new strain of bird flu is highly contagious and can spread rapidly through wildlife populations. As wild birds can carry the virus without appearing sick, it is crucial to prevent contact between domestic animals and wild birds to minimize the risk of transmission. Researchers are closely studying the new strain to better understand its potential impact on wildlife and humans. It is important to note that avian influenza poses a low risk to humans, but proper hygiene practices and avoiding contact with infected birds remain essential precautions. The spread of avian influenza to wild mammals is a reminder of the interconnectedness of wildlife populations and the potential for viruses to adapt and cross species boundaries. Continued monitoring and research are crucial to mitigate the risks associated with this highly contagious disease.
