<human>: I've heard that the swine flu outbreak is a serious concern. How dangerous is it?
<bot>: The current strain of H1N1 influenza virus is not as deadly as the 1918 pandemic strain, but it's still quite dangerous. It can cause mild to moderate symptoms such as fever, cough, sore throat and body aches, but in some cases it can lead to more severe symptoms including pneumonia, bronchitis, and even death.
