**Avian Influenza Surveillance Dashboard Update** The USDA's Wild Bird Avian Influenza Surveillance Dashboard will be updated weekly on Wednesdays to reflect the latest data on avian influenza in North America. **New CDC Recommendations** The CDC has developed new interim recommendations for the prevention, monitoring, and public health response to avian influenza. These recommendations are based on the latest scientific data and best practices. **What is Avian Influenza?** Avian influenza (AI) is caused by an influenza type A virus that can infect poultry and other birds. The virus can cause a range of clinical signs, from mild respiratory symptoms to severe disease and death. **Distribution of Highly Pathogenic Avian Influenza** The USDA is currently tracking the distribution of highly pathogenic avian influenza (HPAI) in North America. HPAI is a highly contagious and deadly form of AI that can cause significant economic losses to the poultry industry. **USDA Resources** The USDA provides a variety of resources on avian influenza, including information on prevention, control, and response. These resources are available online at the USDA website. **For More Information** For more information on avian influenza, please visit the following websites: * USDA Wild Bird Avian Influenza Surveillance Dashboard: https://www.aphis.usda.gov/aphis/ourfocus/animalhealth/animal-disease-information/avian/avian-influenza/wild-birds * CDC Avian Influenza: https://www.cdc.gov/flu/avianflu/index.htm * USDA Avian Influenza: https://www.usda.gov/avian-influenza

**Avian Influenza: A Public Health Concern** Avian influenza, commonly known as bird flu, is a viral infection that primarily affects birds. However, there have been instances where the virus has jumped from birds to other animals, including humans, raising concerns about potential pandemics. **Transmission to Humans** While transmission of avian influenza viruses to humans is relatively rare, it can happen through direct contact with infected birds or their bodily fluids. Inhalation of airborne droplets or contact with contaminated surfaces can also lead to human infection. **Pandemic Risk** Over the past century, there have been four influenza pandemics, all caused by avian influenza viruses that mutated and gained the ability to spread easily among humans. These pandemics resulted in significant global morbidity and mortality. **Transmission to Animals** Avian influenza viruses can also spread to other animals, such as pigs, cats, and horses. In some cases, these viruses can infect multiple animal species, potentially creating a reservoir for human infection. **Symptoms in Humans** Human infection with avian influenza can range from mild to severe. Symptoms typically include fever, cough, sore throat, muscle aches, and fatigue. More severe cases may develop complications such as pneumonia, respiratory failure, and organ damage. **Prevention and Control** Preventing the spread of avian influenza is crucial for public health. Maßnahmen umfassen: * Avoiding contact with infected birds or their bodily fluids * Cooking poultry thoroughly before consuming * Practicing good hygiene, including handwashing and respiratory etiquette * Vaccinating poultry and livestock to reduce virus circulation * Surveillance and early detection of avian influenza outbreaks **Conclusion** Avian influenza remains a serious public health threat. Understanding the transmission and potential pandemic risk of these viruses is essential for implementing effective prevention and control measures. By working together, we can reduce the risk of avian influenza outbreaks and protect our communities from potential pandemics.
**Bird Flu Outbreak Raises Pandemic Concerns** **April 5, 2024** Multiple states across the US are experiencing outbreaks of bird flu among dairy cows, with at least one case of infection reported in a farmworker in Texas. These incidents have sparked fears that the virus could pose a significant threat to human health. **Potential for Zoonotic Transmission** Health officials are concerned that the highly pathogenic avian influenza (HPAI) A H5N1 viruses responsible for the outbreaks could potentially spread to humans. The emergence of zoonotic strains of bird flu viruses has been a growing concern worldwide. **Developing a Candidate Vaccine** In response to these concerns, researchers are working to develop a candidate vaccine virus (CVV) that could protect against the HPAI A H5N1 virus. The CVV is designed to be both safe and effective in preventing infection in humans. **Modernizing Flu Vaccination** The US government has set a goal of delivering first doses of a flu vaccine within 12 weeks of the declaration of an influenza pandemic. This plan, known as the "10-Year Playbook," aims to modernize the flu vaccination process to ensure a rapid response to potential emergencies. **Vaccine Safety Concerns** Traditional flu vaccines use inactivated or live attenuated viruses, which can pose biosafety risks. Subunit vaccines, on the other hand, offer higher biosafety and immunogenicity. Researchers are exploring the use of subunit vaccines to develop a safe and effective CVV for bird flu. **Conclusion** The recent bird flu outbreaks in the US are a reminder of the potential risks posed by zoonotic viruses. Researchers and health officials are actively working to develop effective vaccines and surveillance systems to mitigate the threat and protect public health.
**Avian Influenza Outbreak Affects Dairy Cows in the US** **April 3, 2024** An outbreak of avian influenza, commonly known as bird flu, is affecting dairy cows in the United States. The Centers for Disease Control and Prevention (CDC) has confirmed the presence of highly pathogenic avian influenza A viruses H5, H7, and H9 in dairy cattle. According to the CDC, avian influenza viruses can cause severe illness and death in poultry and other birds. However, human infections with these viruses are uncommon, although they have occurred sporadically worldwide. Scientists are closely monitoring the ongoing global avian influenza outbreak, which has resulted in the death of millions of birds. The CDC's H5N1 Bird Flu Technical Reports provide the latest information on this outbreak. The spread of avian influenza in dairy cows raises concerns about potential transmission to humans through the consumption of contaminated dairy products. However, there is currently no evidence to suggest that this is occurring. Dairy farmers are advised to implement strict biosecurity measures to prevent the spread of the virus to their herds. These measures include: * Restricting access to poultry and other birds * Using personal protective equipment (PPE) when handling livestock * Disinfecting equipment and surfaces regularly * Vaccinating cattle against avian influenza The CDC recommends that people avoid contact with sick birds and poultry products that may be contaminated with the virus. If you have any symptoms of avian influenza, such as fever, cough, or shortness of breath, contact your healthcare provider immediately. The USDA and state animal health officials are working to contain the outbreak and prevent its further spread. Consumers are advised to follow the CDC's recommendations for safe handling and consumption of dairy products.
