Then there’s the issue of susceptibility. Flu virus need to be able to latch onto cells before they can invade them.“If it doesn’t get into a cell, nothing happens. ... The virus just swims around,” explained Juergen Richt, a researcher at Kansas State University.

But those docking spots — sialic acid receptors — aren’t found uniformly throughout the body, and differ among species. One recentdocumented the presence of bird flu-friendly receptors in dairy cattle mammary glands.Eye redness has been a common symptom among people infected by the current bird flu strain. People who milk cows are eye level with the udders, and splashes are common. Some scientists also note that the human eye has receptors that the virus can bind to.

published this month found ferrets infected in the eyes ended up dying, as the researchers demonstrated that the virus could be as deadly entering through the eyes as through the respiratory tract.Why didn’t the same happen in the U.S. farmworkers?

Some experts wonder whether people have some level of immunity, due to past exposure to other forms of flu or to vaccinations. However, a study in which human blood samples were exposed to the virus

there’s little to no existing immunity to this version of the virus, including among people who’d had seasonal flu shots.“He sent me a message saying he wasn’t going to take part and I responded and then talked to him by phone,” Spalletti said. “There are players who deserve to be here just as much as he does.”

Acerbi said on Instagram that he felt disrespected.“I don’t want to stay where I’m not really wanted and it’s clear that I’m not part of the coach’s plans,” Acerbi wrote.
