No evidence
There is no evidence bird flu is currently more easily spread human-to-human, although there is always a chance the virus may evolve to more easily transmit among humans. Most human infections with bird flu can be traced to unprotected close contact with ill or dead animals.
While human to human transmission of bird flu is reported to be very rare, I have no doubt Fauci has someone diligently working on a mutation that would work. Reminds me of the recent meme that they are at it again because we didn’t hang them the whole first time.
