Ever heard of bird flu? It's a virus that's been making headlines recently. The virus, called H5N1, has been spreading through poultry and even dairy cows. In the United States, the Centers for Disease Control and Prevention has reported 66 human cases so far, with most being in California. The virus is a concern because it can mutate and become more easily spread among people.

Scientists are keeping a close eye on the situation. They're tracking the virus to understand how it's spreading and how it might change. So far, people have caught the virus from poultry and cows, but there's no significant evidence of it spreading from person to person.

One of the interesting facts about bird flu is that it can infect all sorts of animals, including cats and cows. Cats, in particular, seem to be more at risk for serious illness. But what about us humans? The symptoms of bird flu are similar to seasonal flu, but it can be more severe.

There's a vaccine for seasonal flu, but if bird flu becomes widespread, we might need a separate vaccine for that. That's why it's important to keep track of the virus and how it's changing.

You might be wondering about raw milk. Well, the Centers for Disease Control and Prevention warns against drinking raw milk because it can contain pathogens like the bird flu virus. Pasteurization, which is heating milk to kill pathogens, is a safe way to protect yourself.
