H5N1 Avian Influenza ("Bird Flu")
You may have heard a lot about avian flu, or “bird flu,” in the media. There are actually many kinds of flu that can infect birds – wild birds as well as domestic birds, like chickens or turkeys. But recently, health officials have been especially concerned about one particular strain of bird flu. Known as “H5N1,” it can make people – as well as birds – severely ill.
The H5N1 flu virus has affected hundreds of thousands of birds, and more than 500 humans worldwide. Health officials are concerned that it could become the next pandemic influenza strain in humans.
However, it’s very hard for people to get H5N1 bird flu from each other. Most people get it from direct contact with birds or their droppings. That’s why there have been so few human cases.
