I have lived in the Phx area for a little over 30 yrs. 28 was working construction. I have eaten tons of dirt & dust. Been caught in hundreds of dust storms. Never had a problem. Some friends were not as lucky. We even had a player for the Diamondbacks retire @ a young age because of it. I wouldn't let fear keep me from traveling through or visiting here. I may come down with it next week but so far I'm good. You can't live in fear or in a bubble.
DON"T PANIC..........
Now there is a lot of flu going around but that is all over the country.
