Trump is directly responsible for the recent spike. He ordered agencies to stop communicating and sharing info and that includes the people who are working on the bird flu problem. A friend of mine from school is a professor at Georgia and works in the field, she's literally friends with multiple people directly involved in the bird flu issue right now. They're all absolutely horrified, and it's the entire reason the egg prices spiked. Everyone realized it's now much harder to determine where bird flu is prevalent so the odds of the problem getting bigger went up astronomically so so are the prices.
