Bird flu, also called avian influenza, is a virus that usually spreads among birds. But sometimes, it can affect people too. Let’s learn about how bird flu impacts humans and what we need to know to stay safe.

What is Bird Flu?

Bird flu is caused by influenza A viruses. These viruses normally infect wild birds and poultry like chickens and ducks. The H5N1 strain of bird flu is especially dangerous. It can make birds very sick and even kill them.

Types of Bird Flu Viruses

There are different types of bird flu viruses:

  • Low pathogenic avian influenza (LPAI): These don’t usually make birds very sick
  • Highly pathogenic avian influenza (HPAI): These can cause severe illness in birds

H5N1 is a type of HPAI virus. It’s the kind that health officials worry about most for humans.

Can Humans Get Bird Flu?

Yes, humans can get bird flu, but it’s rare. Most human cases happen after close contact with infected birds or their droppings. The virus doesn’t spread easily between people.

How Bird Flu Spreads to Humans

People can catch bird flu by:

  • Touching infected birds
  • Touching surfaces with bird droppings
  • Breathing in dust from bird droppings
  • Visiting live bird markets

You can’t get bird flu from eating fully cooked chicken or eggs.
