Q

A woman aged 22 is 10/52 pregnant and is exposed to shingles. Her family is concerned about her safety and any potential problems the shingles might cause
for his unborn grandchild. What specific advice do you need to give for his daughter and the unborn child?

A

There is increased morbidity associated with Varicella in adults, including pneumonia, hepatitis and encephalitis. Pregnant women who develop chicken pox should contact their GP immediately. PO acyclovir should be prescribed if the rash is present within 24 hours of it appearing. If the woman develops varicella or shows serological conversion in first 28/7 of pregnancy she has a small risk of Fetal Varicella Syndrome (FVS).

Pregnant women with unclear history of chicken pox who have been exposed should be offered a blood test to determine immunity. If not immune they should be offered Varicella Zoster Immunoglobulin (VZIG). This is effective up to 10/7 after contact. The aim of VZIG is that it may prevent chicken pox or attenuate it and reduce risk of FVS.
