That's probably not the best idea.  Try sinking a length of the hose underwater till filled and then pull it out of the tank, towards your bucket, to start the siphon.  Much better.  
I'm with Pledo and Bill; Vibrio and Myco are really common, both in freshwater and saltwater systems.  Its not something to be totally paranoid about, but it is something to consider if you are otherwise immunosuppressed, have actively healing cuts, or are prone to infection.  
So now that we're all informed about the potential bacterial issues, lets talk about all the viruses that are floating out in the water alongside the bacteria!  :strooper:
Ok, not really.  But its like the bacteria, there's LOTS.
