New K Variant Flu Outbreak

Scientists have discovered a new type of flu called the K variant.

It's a mutated version of an already harsh flu strain called H3N2.

This new variant can change quickly and evade some of the protection from this year's flu vaccine.

It's especially dangerous for older adults.

The K variant isn't a completely new flu, but it's different enough to cause concern.

Scientists are studying it to understand how it spreads and how to protect people from it.
