I just told my sitter not to come. She was vomiting for 3 hrs this morning. But now she says she's fine. Last evening she felt "tired and cold". She thought it was food, but no one else got sick. She's all afraid I'll fire her b/c lately she's missed a lot of work with back problems and stuff.

If it is a current virus, what are the symptoms and when do you think it would be ok to have her back?
