The virus that causes herpetic whitlow- usually HSV
-1 (but sometimes HSV-2) is related to the same virus that causes chicken pox. We call that virus VZV or varicella zoster virus
. These viruses are found in the 'herpes' family of viruses. Great observation. I hope though you're not suffering too badly from these nasty viruses. There is a chickenpox vaccine
out there BTW.
