A new strain of bird flu has been detected in the United States, and it has sparked a lot of concerns among farmers and general population. Bird flu is a disease caused by 'avian influenza A virus' that usually spreads among birds, but one subtype of this virus which is A(H5) has caused an outbreak recently, not only among wild birds but US poultry and dairy cows as well. What really caused more issues is the fact that some rare forms of the virus has now spread to humans. While the risk of infection for humans is low, CDC has been monitoring people who have had exposure to animals and could get infected. There are 67 confirmed human cases, and one death reported with the H5N1 strain. A new strain of bird flu, called H5N9, has now been found in US for the first time. Like other viruses, there is always a chance for existing ones to mutate and become worse, like the current bird flu strain was found on a duck farm in California. This discovery means that we need to keep a close watch on bird flu to ensure it doesn't cause bigger problems, and learn more about this new type to understand how it spreads and if it's dangerous to people.Another Bird Flu Still Spreading The reason why this has caused so much panic is because US is already dealing with H5N1 bird flu and another strain, H5N1 began spreading quickly across the country. H5N1 is causing lots of problems for chicken and turkey farmers, and many birds have had to be killed. Cases of cows being infected with the virus are also worrying.Mixing and Changing Bird Flu Experts are worried about how bird flu can mix and mutate- this is called "reassortment". This is a phenomenon where two viruses mix and become something worse. We already know that this new strain can infect cows, so it is very likely that another mutation could become dangerous for human beings as well. Because we have two different bird flu types in the US right now, H5N1 and H5N9, there's a higher risk of reassortment happening. Scientists are watching closely to see if this happens and if any new, dangerous viruses pop up. The H5N9 bird flu found in California is actually a mix of the H5N1 bird flu that's already here and another existing bird flu. This is usually how viruses mix and mutate, which is a cause of concern for scientists, as the new virus could be immune to the existing vaccinations and treatments. The fact that H5N9 is a mix reminds us we need to keep studying these viruses to understand them and protect ourselves. Is there a Vaccination for Bird Flu?There is no bird flu vaccine currently available for people, but the U.S. is investing in emergency preparedness. Companies like CSL Seqirus, Sanofi, and GSK are developing vaccines, while Moderna works on an mRNA flu vaccine. To prevent infection, avoid contact with sick birds, contaminated surfaces, and raw animal products.Preventing Bird Flu Among PeopleA bird flu vaccine isn’t currently available for public use, but the U.S. is preparing for potential outbreaks. The government has invested in vaccine production with CSL Seqirus, Sanofi, GSK, and Moderna’s mRNA flu vaccine research. According to the CDC, in order to prevent infection, you must:Avoid contact with sick or dead birds, contaminated surfaces, and raw animal products. Use protective gear if handling animals suspected of infection. Wild birds can carry the virus even if they appear healthy. Maintaining a safe distance from wildlife and not consuming raw milk or its products from infected animals to minimize the risk of avian influenza transmission.
