My husband came down with a case of chicken pox a year ago. Our family doctor said he very rarely sees it anymore except with immigrants. We traced his whereabouts over the previous week and we think he got it from a food server at a deli in his office building.
Probably not. The incubation period of chickenpox is 3 weeks not one.
I have been blessed with excellent health my entire life. But the one thing that has from time to time gotten me has been chicken pox-related viruses. At first, no one connected them. I had chicken pox twice as a child (yes, it CAN happen), shingles as a teen-ager and an eye infection in college that was shown to be a herpes virus related to the above IIRC. So when I had my own child and she got chicken pox, I talked to her doctor about my health experiences, and he said that it seemed I was just vulnerable to this type of virus and to keep a watch out. Fortunately, I have no longer gotten anything else similar. We're all so different!
