Scientists are tracking a deadly bird flu outbreak that has infected wild birds in more than 30 states. Purging the nation's poultry supply may not be enough to keep the virus from sticking around.
Nearly 23 million birds have died as a highly pathogenic bird flu virus tears its way through farms and chicken yards. It has spread to at least 24 states in less than two months.
Bird flu has been confirmed in poultry in 17 states since the start of the year. Whether the outbreak will affect the price of eggs and poultry depends on how widespread it becomes, an expert says.
