Sunny some good and some bad. I hope you don't mind. My sister in law teachers in a child care centre she caught InfluenzeA in 2008 and m/c during her illness at 11weeks. 6months later she fell pregnant again and had a healthy baby boy. I don't know if the influnzaA deinately caused the m/c but the Dr said it did. I am a nurse and have caught some things at work but usually when you first start working you might catch a few things but it does get better when you immune system increases from the exposure. And I must say there are a large number of childcare workers, teachers and nurses having babies so I think the risk is pretty low. I would go for the childcare position if thats what you want to do.
