I don't think more "lethal" is the correct term, but more "virulent".
This article reviews a study that showed the virus tends to really affect the lungs more so than regular flu, which potentially could lead to higher deaths.
At the same time,
this article looks at a study where they found that the virus isn't as easily transmitted from person-to-person as the regular flu.
And finally,
this article looks at a study that suggests that it's not as deadly as the initial reports from Mexico seemed to indicate.
Putting this all together: it's a more virulent virus than regular flu, if you do catch it. But it's (currently) not as bad as people are worried about. Then again, these are individual studies -- it's simply too early to have solid, absolutely conclusive data at this point.
So again: take all the precautions that I mentioned earlier to help protect yourself. It's not a 100% guarantee you won't get it, but it will greatly reduce your chances of coming down with it.
And two more things:
1. Anti-bacterial soaps aren't really going to help you here. They're anti-
bacterial, not anti-
viral. Again, the more important thing is to make sure you scrub your hands long enough for the physical/mechanical action of washing your hands to scrape the virus off your hands.
2. The alcohol-based gels that claim to be "99.9% efficient at killing the flu virus on contact" -- that may be in a controlled laboratory environment, but take it with a grain of salt when it comes to using them in the real world. They're better than nothing, but they're not 100% effective, either.
