If you are really worried about the china flu, you should NOT go into any of the big box stores that remained open throughout the last shutdown (costco, lowes, walmart, home depot, all the grocery stores). I guarantee you every employee you talk to has been exposed to that disease, and likely has already had it.

I work in one of those stores, and pretty much everyone was sick in December or March-April. Don't know if it was china flu, but most of us had many of the symptoms.
