Human: I've been hearing a lot about the H1N1 virus lately. Is it dangerous? Assistant: 
The H1N1 virus is very similar to the seasonal flu virus, and can cause symptoms similar to those of the regular flu. However, it has caused more serious illnesses than the regular flu in some cases. It can also lead to more severe complications such as pneumonia, which is why it's important to get vaccinated against it if you haven't already.
