The only cases of bird flu in the United States so far have been caused by a strain of flu virus differ from what is sweeping through Asia, Africa and Eastern Europe, killing thousands of wild and domestic birds . Wild birds carry a number of these viruses, but only one strain, H5N1, which has governments around the world who are concerned both about the risk to the poultry industry and because the H5N1 virus has killed 140 people a day. Countries around the world are making efforts to inform the public about the safety standards that can lead to the prevention of avian influenza.
Scientists hope to finally see the H5N1 bird flu in the United States, but may not appear. The concern is that migratory birds from Asia could spread the H5N1 virus to migratory birds in the Americas, when the two come together in Alaska. Therefore, the prevention of avian influenza H5N1, at this point focuses on Alaska. The U.S. Geological Survey and the Department of Agriculture have joined in an effort to prevent avian flu H5N1, which includes testing and stool samples of feathers from around 150,000 wild birds, especially waterfowl. Scientists believe that if the H5N1 bird flu found in U.S. is likely to waterfowl in the first place. Unlike poultry, wild birds may carry the avian influenza virus H5N1 in the United States and around the world without dying. In areas of the world where wild birds mingle freely with domestic poultry can infect your water supply or to transmit the virus through feces and other secretions, but the USDA in the United States, as well as industry standards decrease the likelihood that the avian influenza virus H5N1 in the United States, in particular the United States, will become a problem.
Large poultry farmers in the United States are now and have always been concerned about avian flu prevention, no matter what strain. They take precautions to protect their birds, because birds are their livelihood. The fences are designed to keep your birds and wild birds out. Workers wearing protective suits, boots and hats for the prevention of avian influenza and other diseases to prevent contamination of poultry.
While there have been some cases of some strains of avian influenza in the United States that led to the destruction of many flocks of chickens in Texas and Virginia, only one case of bird flu in the United States affecting a human being. Even if efforts to prevent avian flu can not deny the possibility of avian flu in the United States, farmers, scientists and government agencies around the world are making efforts to identify and contain outbreaks quickly. Cook meat thoroughly.
Although many different influenza viruses infect birds and who for many years, the history of H5N1 avian influenza in humans is relatively short, because the case was first observed in 2003 occurred in China and Viet Nam according to the “World Health Organization (WHO). The wild birds carrying the virus, but generally are affected by them. It is believed that the degree of difference in symptoms of avian influenza is related to virus strain infect birds. Microbes cause severe symptoms of avian influenza H5N1 in poultry and in many cases whole herds must be destroyed to prevent the spread of the disease.
Microbial infection of bird flu among humans is rare and usually occurs in people who handled infected poultry or farms of care and multiple strains, causing only mild disease. The history of avian influenza virus H5N1 has been shown that this strain can be fatal to humans. There have been 253 confirmed human cases since 2003, killing 148 people. This high percentage of deaths (58%) after infection with avian flu germs, scientists and public health officials around the world worried.
The virus usually change slowly over time and the human immune system can identify because they are very similar to existing viruses and respond quickly. On rare occasions in the past, viruses have changed suddenly, called antigenic shift, causing serious illness, a number of human deaths and epidemics worldwide. Sometimes, the virus has infected humans before, but had infected other animals like pigs and poultry. From the history of avian influenza virus H5N1 has been shown to infect humans, scientists believe they could become highly contagious among them, causing pandemics and epidemics in the world. Scientists believe that only two proteins in the microbes of the H5N1 avian influenza virus have to be changed, so it becomes easily transmissible among humans as seasonal influenza.
