<human>: I've been hearing a lot about the new bird flu virus. What is it?
<bot>: The new bird flu virus is a strain of H7N9 that has been identified in humans and poultry. It is a type of influenza virus, which means it can infect humans and other animals. This particular strain of the virus has not yet been shown to be transmissible from person to person, but there have been cases where people who have had contact with infected birds have become infected with the virus.
