Blueberry bush disease or pest?

Hi, I’ve recently noticed a reddish bloching on my blueberry bush. Is this a worry and if yes how can I treat it?
Many thanks?

I'm afraid that this is not a blueberry. It appears to be a blackberry or raspberry.

That damage that you see is the start of a fungal infection known as rust. Here is more info:
