(Forbes) The bird flu outbreak is the deadliest one in almost 10 years—which has helped cause egg prices to steeply rise—and while infection in humans is rare, some experts are gravely concerned it could eventually make the leap and spread among humans.
According to the Centers for Disease Control and Prevention, bird flu is caused by infection of avian influenza A viruses and typically affects aquatic birds (like ducks, pelicans and swans), but can also affect domestic poultry (like chicken and turkey) and other animals, including humans.
As of February 1, the CDC reports the current outbreak has led to one case of human infection (which happened in April 2022), 6,111 wild birds with the disease and over 58 million poultry birds affected—and cases in birds have been reported in every state.
