On H7-strains https://www.theatlantic.com/science/archive/2017/10/h7n9-flu-pandemic/543318/" rel="nofollow - https://www.theatlantic.com/science/archive/2017/10/h7n9-flu-pandemic/543318/ :“When you compare H5 and H7 viruses, I think H7 are more worrisome,” says Kawaoka. That’s because the H5 viruses need several further mutations to spread between mammals, as Kawaoka showed in controversial lab experiments where https://www.nature.com/news/mutant-flu-paper-published-1.10551" rel="nofollow - he engineered strains with those mutations . But H7 strains apparently don’t need such tweaks. The strains that are out there right now are already capable of spreading between ferrets.
