Cows from Texas likely infected healthy cows in Ohio and probably spread the virus to cats, a racoon and wild birds on farms through their milk, scientists said, raising fears the virus may be changing to better infect mammals like humans.

U.S. health officials have announced two more bird flu cases among farmworkers. But here’s some good news: A new study in Michigan suggests the virus is not causing asymptomatic infections in people.

A new study provides evidence that a spillover of avian influenza from birds to dairy cattle across several U.S. states has now led to mammal-to-mammal transmission—between cows and from cows to cats and a raccoon.

Bird flu typically spreads among birds, but there have been recent outbreaks among cattle in the U.S., and one Texas man contracted the virus from sick cows. Here’s why so many experts are worried about a possible new pandemic.

U.S. health officials on Friday said a new study in Michigan suggested the bird flu virus is not causing asymptomatic infections in people, while also announcing two new human cases in Colorado.

They constantly mutate, producing new strains that challenge immune systems primed to fight earlier varieties. That’s what makes flu a life-long threat to humans and the animal species — mainly birds — that are vulnerable to it.
