Human: What do I need to know about the new swine flu? Assistant: 
The most important thing you need to know is that it’s a highly contagious virus that can spread quickly. It’s caused by a type of influenza called H1N1, which is similar to the strain that caused the 1918 pandemic. Symptoms include fever, coughing, sore throat, body aches, and fatigue. People who have been exposed to the virus may develop more severe symptoms such as difficulty breathing, pneumonia, or even death. It is important to stay away from people who are sick and wash your hands regularly.
