I know this subject has been discussed a number of times in the past, although there appears to be no official guidance on the Vasculitis UK website. Clearly the big risk in immunosuppressed people is if you have never had it and you are exposed to it. However if you have already had chickenpox a child the risk of re-activated infection and precautions to take are not entirely clear. I recently had a slight exposure to chicken pox from by grandson, shortly before his spots appeared. I did have chickenpox as a child but I have been staying clear of him since as a precaution. However I am supposed to be looking after him and is younger brother (who could well be in the disease incubation period by now) on Friday. Has anyone had any experience of being re-infected with chickenpox? Also I have heard that you should ask your Dr to be given Acyclovir if you are immunosuppressed and have been exposed to chickenpox as a precaution. However that might be applying to people who have not had the pox previously. Has anyone had any experience?
