Is shingles contagious?
It is not possible to catch shingles from someone else with the condition, or from someone with chickenpox.
However, it is possible for someone who has never had chickenpox to catch it from someone with shingles, as the shingles blisters contains the live virus.
In the UK, chickenpox is so common during childhood that 9 out of 10 adults have already had it and will not be at risk from someone with shingles.
Catching chickenpox
The blisters that develop as a result of shingles contain virus particles. If you have not had chickenpox before, you can catch it from direct contact with the fluid from the blisters of someone who has shingles, or from something that has the fluid on it, such as bed sheets or a towel.
If you have shingles, you are contagious until the last blister has scabbed over. This will usually occur after about 10 to 14 days.
Preventing the virus spreading
If you have the shingles rash, do not share towels or flannels, go swimming, or play contact sports. This will help prevent the virus being passed on to someone who has not had chickenpox.
You should also avoid work or school if your rash is weeping (oozing fluid) and cannot be covered.
Chickenpox can be particularly dangerous for certain groups of people. If you have shingles, avoid:
women who are pregnant and have not had chickenpox before as they could catch it from you, which may harm their unborn baby
people who have a weak immune system, such as someone with HIV or AIDS
babies less than one month old, unless it is your own baby, in which case your baby should have antibodies (proteins that fight infection) to protect them from the virus
Once your blisters have dried and scabbed over, you are no longer contagious and will not need to avoid anyone.
