A friend of mine had several illnesses in a short time -- he was really worried, and the doctor diagnosed "rotten luck." Seems like a good diagnosis, as this was years ago and my friend is healthy. Maybe it's just chance?

Hand washing is my favorite preventive. I do think stress or worry wreaks havoc on the immune system; my mother went through a two-year terminal illness and I got cold after cold plus upset stomachs.

Hope you are healthy soon!
