Chapters 0:00 Introduction 0:30 Causes of Bird Flu 2:13 Symptoms of Bird Flu 2:59 Treatment and Prevention of Bird Flu Avian influenza, known informally as avian flu or bird flu, is a variety of influenza caused by viruses adapted to birds.[note 1] The type with the greatest risk is highly pathogenic avian influenza (HPAI). Bird flu is similar to swine flu, dog flu, horse flu and human flu as an illness caused by strains of influenza viruses that have adapted to a specific host. Out of the three types of influenza viruses (A, B, and C), influenza A virus is a zoonotic infection with a natural reservoir almost entirely in birds. Avian influenza, for most purposes, refers to the influenza A virus. Though influenza A is adapted to birds, it can also stably adapt and sustain person-to-person transmission. Recent influenza research into the genes of the Spanish flu virus shows it to have genes adapted from both human and avian strains. Pigs can also be infected with human, avian, and swine influenza viruses, allowing for mixtures of genes (reassortment) to create a new virus, which can cause an antigenic shift to a new influenza A virus subtype which most people have little to no immune protection against. Avian influenza strains are divided into two types based on their pathogenicity: high pathogenicity (HP) or low pathogenicity (LP). The most well-known HPAI strain, H5N1, was first isolated from a farmed goose in Guangdong Province, China in 1996, and also has low pathogenic strains found in North America. Companion birds in captivity are unlikely to contract the virus and there has been no report of a companion bird with avian influenza since 2003. Pigeons can contract avian strains, but rarely become ill and are incapable of transmitting the virus efficiently to humans or other animals. Between early 2013 and early 2017, 916 lab-confirmed human cases of H7N9 were reported to the World Health Organization (WHO). On 9 January 2017, the National Health and Family Planning Commission of China reported to WHO 106 cases of H7N9 which occurred from late November through late December, including 35 deaths, 2 potential cases of human-to-human transmission, and 80 of these 106 persons stating that they have visited live poultry markets. The cases are reported from Jiangsu (52), Zhejiang (21), Anhui (14), Guangdong (14), Shanghai (2), Fujian (2) and Hunan (1). Similar sudden increases in the number of human cases of H7N9 have occurred in previous years during December and January.
North American outbreaks of avian influenza A(H7N9) - often referred to as "bird flu" - have public health officials paying close attention. The Centers for Disease and Prevention (CDC) says the risk to the public's health from the H7N9 virus outbreak in commercial poultry in the U.S. is low. The U.S. Department of Agriculture says this is not the same virus that has impacted poultry and infected humans in Asia. In China, there have been recent confirmed cases of human infections of H7N9 virus. Mayo Clinic infectious diseases specialist Dr. Pritish Tosh says, "When we’re talking about avian influenza cases affecting humans, it is in people who have had close contact with poultry or other types of birds that could carry or get infected with avian influenza. Often in these outbreaks, you will see a handful of cases of people who have had no contact with a sick bird as part of the outbreak but instead got it from somebody else who got it from a sick bird." Dr. Tosh says, "It doesn’t suggest very efficient human-to-human transmission, but it does get us a little concerned. When we start to see really highly efficient transmission between people, human-to-human transmission of a novel strain, something that in our general population has not seen, that is when we get really concerned that this could be the next pandemic strain." Most avian influenza is spread worldwide by migratory waterfowl which then can pass it along to poultry. In humans, influenza is a respiratory illness. In birds, it is a gastrointestinal illness. Dr. Tosh says, "Avian influenza viruses infecting humans are similar in many ways to human influenza viruses infecting humans. It's often spread through respiratory droplets or other respiratory kinds of secretions from person- to-person. Often the person who’s getting it from a sick bird is getting it through their droppings. But when it’s spread from person-to-person it’s through their respiratory secretions, usually through droplets." The CDC offers these tips to prevent exposure. Avoid wild birds and observe them only from a distance. Avoid contact with domestic birds (poultry) that appear ill or have died. Avoid contact with surfaces that appear to be contaminated with feces from wild or domestic birds. "It’s important that if somebody were to go near poultry, whether in the U.S. or elsewhere in the world and develop some sort of respiratory infection, that they let their health care provider know," Dr. Tosh. Human infections with avian influenza A (H7N9) virus were first reported in China in 2013. More health and medical news on the Mayo Clinic News Network 🤍
BIRD FLU EPIDEMIC 2021 - Everything you need to Know about Bird Flu/Avian Influenza Support on Patreon : 🤍 Avian influenza, known informally as avian flu or bird flu, is a variety of influenza caused by viruses adapted to birds. The type with the greatest risk is highly pathogenic avian influenza. Bird flu is similar to swine flu, dog flu, horse flu and human flu as an illness. Avian influenza, known informally as avian flu or bird flu, is a variety of influenza caused by viruses adapted to birds. The type with the greatest risk is highly pathogenic avian influenza (HPAI). Bird flu is similar to swine flu, dog flu, horse flu and human flu as an illness After Delhi and Maharashtra reported confirmed cases of bird flu, the number of states and Union Territories recording avian influenza outbreak has gone up to nine. The other states to report bird flu are Himachal Pradesh, Haryana, Rajasthan, Madhya Pradesh, Gujarat, Uttar Pradesh and Kerala. Haryana has reported maximum deaths of birds — over 4 lakh in past few weeks. How serious is this bird flu outbreak? The bird flu outbreak became a worry in the first week of January after many states started reporting unusual deaths of large number of birds — wild, migratory and also poultry. The samples were tested and found to be a case of infection caused by Influenza Type-A virus, primarily H5N1, which is considered a Highly Pathogenic Avian Influenza (HPAI) variant. Other strains such as H7N1, H8N1 or H5N8 also cause bird flu and belong to the same HPAI category. While bird flu outbreak in Himachal Pradesh has been caused by H5N1, the samples from Kerala, Madhya Pradesh and Rajasthan have shown the presence of H5N8 variant. Wild birds are considered the natural reservoirs of the bird flu viruses and it is typical of an outbreak to coincide with the season of arrival of migratory birds, which also take the virus to poultry. According to the early warning system of the World Organization for Animal Health (WOAH), bird flu outbreaks were reported in several countries including Taiwan and Japan to a number of European countries and more than 48 lakh birds died or were culled in December 2020. In India, the Centre has asked state governments to follow the National Action Plan for Prevention, Control and Containment of Avian Influenza 2021. It has asked the state governments to take all the measures to make sure that the outbreak is curbed. State governments have started culling the birds in affected areas. For example, Kerala has planned to cull around 70,000 birds in the worst-affected Alappuzha district. Threat to humans The viral strain, H5N1 has a history of spreading over to humans from birds. Another variant H7N9 is considered very lethal to humans. However, the instances of bird flu among humans have been uncommon. The first recorded bird flu outbreak among humans was in 1996-97 in Hong Kong and China. The mortality rate has been high, however, in all human outbreaks. Six of 18 cases in Hong Kong had led to death. The World Health Organization (WHO) says human cases of bird flu occur “occasionally” but when it happens, the mortality rate is about 60 per cent. This is often seen with diseases caused by pathogens new or unknown to human bodies. The human-to-human transmission is “difficult”, according to the WHO, which, however, says there is a possibility of the H5N1 mutating and posing a pandemic threat among humans. According to the WHO data, 862 cases of bird flu among humans have been recorded in 17 countries since 2003. These are the cases confirmed through lab testing. Of these, 455 persons died. The last instance of human case bird flu infection was reported from China in October 2020. The patient was a three-year-old girl, who displayed mild flu-like symptoms. Economic impact of bird flu Every month, India consumes around 30 crore eggs and 900 crore chickens sourced from poultry farms. The poultry sector of India is worth Rs 80,000 crore, of which more than three-fourths is from the organised sector. Thousands of birds are being culled. Poultry farmers are compensated for the loss caused due to culling. The government had paid over Rs 26 crore to farmers between 2006 and 2018 on account of culling to contain spread of bird flu in India. The farmers, however, complain that compensations do not cover for their profit that they could have earned from regular business. During this period, India culled more than 83 lakh birds at 225 epicenters of bird flu across the country. India has adopted a practice of building bio safety bubble around poultry farms to mitigate the chances of wild birds coming in close contact with reared birds. About the safety concerns over eating eggs and chickens, scientists say it is safe to consume poultry products that are properly cooked at over 60-70 degree Celsius. Any temperature above this kills viruses.

What are Zoonotic Influenzas? Zoonotic influenzas spread around the world in yearly outbreaks, resulting in about three to five million cases of severe illness and approximately half a million deaths. ‘Zoonotic’ means they are caused by pathogens, in this case viruses, that have hopped from infected animals to humans.

A highly contagious strain of avian flu is spreading to several states in the U.S. Wisconsin is the latest state to report finding h5n1 – the scientific name for the avian flu – after discovering it in a commercial chicken flock. Avian flu has now been found in 15 states. Cross-species spread is possible, though not likely. Dr. William Schaffner of Vanderbilt University Medical Center told CBS News, “It's a very rare event, it requires very close association of the human with the bird.”
In addition to being a public health threat, avian influenza is also costly and potentially devastating to people whose livelihoods depend on raising poultry. To enable faster detection of bird flu and identification of its subtypes, scientists at Wageningen Bioveterinary Research in The Netherlands developed a multiplex assay using xMAP® Technology. In this 20-minute video presentation, veterinarian Evelien Germeraad reports on the development and validation of that assay. Wageningen Bioveterinary Research, part of Wageningen University & Research, is a national reference lab for infectious animal diseases, receiving samples for testing from all over the country. The lab tests cattle, poultry, goats, and other types of animals for illnesses ranging from rabies and tularemia to psittacosis and foot-and-mouth disease. Scientists there run as many as 300,000 assays per year, of which 20,000 are deployed for avian influenza, the main focus of Germeraad’s talk. 🤍

Back in 2014, “bird flu” was flooding headlines. And well this year, it’s happening again. 🤍ryuji_chua explains what you need to know. Just like humans and other animals, birds sometimes get sick. And sometimes, they have their own pandemics. That’s what that was. Birds everywhere got infected with the H5N1 virus, or bird flu, millions of whom were birds in factory farms like chickens, ducks, and turkeys. In fact, because factory farms cram so many animals tightly together in filthy conditions, they’re actually ideal environments for viruses like bird flu to break out. And so this year, unsurprisingly to experts, bird flu is back. Since January of 2022, the USDA estimates that over 47 million birds have been infected with it, just in the US. For perspective, that’s like the entire human population of Spain. Whenever this happens, the important thing to do is to contain the spread of the virus—so it doesn’t infect every other bird on the planet or start the next human pandemic. And the way that humans do this is that as soon as one bird on a farm tests positive, they take the entire flock they came from, and kill all of them. And this has just been an animal welfare disaster. According to a report by the 🤍AnimalWelfareInstitute based on 🤍UsdaGov data, the 3 main ways we’ve been doing this so far are suffocating the birds by filling barns with CO2, choking the birds by filling barns with foam and this thing called “VSD”. Now of those 3 methods, VSD is the cheapest and therefore also the most common, by far. But it’s also the one that causes the birds the most suffering. It stands for “ventilation shutdown” and it refers to the process of shutting down the ventilation in a barn, followed by turning up the heat, gas, or steam. This causes the barn’s temperature to skyrocket, essentially turning it into a giant oven, and the birds die by suffocating or overheating, often after suffering for hours. In fact, 🤍AnimalOutlook recently obtained public records from experiments that were testing VSD on chickens, and this is what those experiments looked like. One worker who helped do this to over 5 million birds called this cooking the animals alive, and due to the extreme suffering this causes the animals, vets have called this the most inhumane method available. So, if bird flu keeps spreading, will it cause the next human pandemic? Well historically, the bird flu virus hasn’t been very good at infecting humans. And since 2003, only 865 humans have been infected. However, over half those cases were fatal, and there’s no guarantee that things won’t change. Viruses mutate all the time, and it wouldn’t be all that surprising if one day bird flu became a big problem for us as well. To summarize, humans have crammed animals in conditions that not only cause them extreme suffering, but also create ideal environments for diseases to break out. Then, when diseases do break out, which by the way, causes them to suffer just like when we get sick, our solution is to kill them by using methods that cause them even more extreme suffering. And while the animal agriculture industry is responsible for this, so are consumers who endorse this cruelty by buying the eggs, chicken wings and other animal products that these animals are made to suffer for.

The Food and Agriculture Organization of the United Nations (FAO) has launched a Media Fellowship Project to document the evolution and impact of Avian Influenza (AI) in Viet Nam. The main objective of this fellowship is to bring about deeper understanding on the impact of AI on the livelihoods of the people through in-depth reporting. FAO has the honor of providing financial support for the selected journalists to enable them favorable condition for their creative job but the compiled products from the Media Fellowship do not reflect neither the opinion nor the official position of the Organization. The film "Danger of Avian Influenza" has expressed how the avian and human influenza caused human fatalities and a loss of poultry. The film has described the disease situations, outbreak control and prevention measures, reasons for disease spreading. The film has also highlighted the severity in human pandemic as well as the concern on public awareness for disease prevention and control. (c) FAO 🤍fao.org
Federal and state authorities say a case of avian influenza has been detected in a flock of commercial broiler chickens in Kentucky near the state’s border with Tennessee. Kentucky State Veterinarian Dr. Katie Flynn said the U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed the presence of highly pathogenic H5N1 avian influenza in samples taken from the premise in Fulton County, Kentucky. Another suspected case in Webster County, Kentucky, is waiting final lab confirmation. Avian influenza does not present a food safety risk; poultry and eggs are safe to eat when handled and cooked properly. There is no risk to the food supply, but birds from the flocks will not enter the food system. No human cases of avian influenza viruses have been detected in the United States.
