Hey SG, when I was working at my last place everyone started coming down with the SV, at least 2 people a day were getting sent home sick. One guy threw up I overheard another woman saying she thought she was healthy but had been ill etc etc. I wasn't always careful at times. It's hard to be careful everyday for 2 months. But I didn't catch it the whole time I was there and nearly everyone did because they all brought food out, ate at their desks, touched food without washing their hands etc etc. It was kinda gross. Plus a lot of the sick people actually shared a communal kitchen (utensils etc) just b/c something is "going around" doesn't mean you will catch it.
Be courageous, believe in yourself, and be the best woman you can be. I'm with you all the way.
