80,000 deaths caused by flu last season, CDC says

An estimated 80,000 Americans died of flu and its complications last winter, according to the US Centers for Disease Control and Prevention. This means it was the deadliest season in more than four decades -- since 1976, the date of the first published paper reporting total seasonal flu deaths, said CDC Spokeswoman Kristen Nordlund.
