Chickenpox and shingles are the results of a virus called varicella-zoster. You may have had chickenpox as a child, so you could be immune to the virus. The virus can be spread by respiratory droplets, such as via coughing. It can also be spread if you come into direct contact with chickenpox blisters that still contain fluid.
Shingles is not a new infection. It’s actually the chickenpox virus that remains in the nerve cells and becomes reactivated. It’s only possible to develop shingles if you had chickenpox in the past. Shingles can be spread only if you come into direct contact with the rash of an infected person.
If you are planning to fall pregnant, it’s advisable to check your immunity to chickenpox with a blood test.
If you are pregnant and exposed to chickenpox or shingles, check your immunity to the virus. If your tests show that you are immune, then you will not contract the virus. If you are not immune, you may need preventative treatment with Varicella Zoster Immunoglobulin, which is an injection of antibodies to inactivate the virus. Immunoglobulin should be given within 96 hours of exposure and is safe in pregnancy.
