The FLU

[S. Frog]

	Hi, and all that.

	I'm not sure if this is the proper place to raise this question, 
and forgive me if it isn't, but I have a question about the flu.
	Actually, three questions:
	Is the flu a retrovirus?
	If it isn't a retrovirus, do I have a faulty definition of what a 
retrovirus is?
	Lastly, is it true that the flu has only been around for like a 
hunred years or so?  And that it mutated from something else, which is 
why human has so little resistence to it when the influenza epidemic 
roared through just after world war I?


	Thanks. :)
