New York's JFK Airport top germ spreader: study

Gross, wear gloves.

...and a mask?

Oh, great, I'm going there later this week. Can I hold my breath for the entire 2h40m transfer time...? ;-)

I've had friends who have become extremely sick from transportation air-conditioning systems while traveling ... mainly in the United States. These include the systems in buses and ships. Now we've got the airports to worry about, too. I've often wondered what kind of diseases are roaming about while seeing all the international travelers at some of these airports over the years. Now we know bugs do flow the air at these places. As Gardner and Viking recommend above, if you are of the nervous kind, wear gloves and a mask ...

As for me, I'll take my chances while mingling with the germs and whatever else floats through the air at these and other airports. So far so good ...
