Is chickenpox infectious?

Yes, it is very infectious. The virus travels in the air and then settles on clothes, bedding, etc. It takes 11-20 days to develop symptoms after catching the virus (the 'incubation period').
Protecting others
A person with chickenpox is infectious from 2-4 days before the rash first appears until all the spots have crusted over (commonly about 5-6 days after onset of the illness). You can usually return to work after this time if you feel well enough. Whilst you are infectious, keep away from people who may get a severe illness if they get chickenpox. These are:
- Pregnant women who have not had chickenpox in the past.
- People with a poor immune system. For example, people with leukaemia, with HIV/AIDS, on high dose steroid medication, or are taking chemotherapy.
Healthy people who have not had chickenpox may also want to avoid catching it. So, friends and family who have not had chickenpox may wish avoid you whilst you are infectious. However, most healthy adults and many children have already had chickenpox, and so are immune.

Just found out today(20/02/08) that my 5 yr old daughter has chickenpox. I am thinking of returning to work at a primary school on monday where i have a pregnant collegue. I have already had chicken pox as a young child, but I am worried that i may be infectious because my friends daughter had it in the new year and my friends boyfriend caught it but he had no contact with her daughter. Please could somene give me some advise. I did call my Dr but wasn't much help. Thank you.

My husband was going to visit his family this weekend but his mother has said no as our 5 yr old is just recovering from chickenpox.The first spots appeared last Friday, when we saw the doctor on Tuesday he said that our son was not infectious from Wednesday.Is there any way my husband could carry this virus to his family (his sister is on chemotherapy)?thanks for your responses.Jane
