The influenza A virus type H5N1 responsible for the recent outbreaks of bird flu has been detected in swine. This has caused some alarm, as swine can also harbor human influenza viruses. There is a fear that a pig co-infected with avian flu and a human influenza A vitus may give rise to a new virus that is as lethal to humans as bird flu, and also capable of human to human transmission. What is this process that could allow this to happen?
