antenatal screening programme
Varicella zoster virus (VZV) is the virus which causes chickenpox. It usually occurs in children under 10 years old, causing a mild infection. If a woman catches the virus for the first time during pregnancy it can make her seriously ill. Her baby may also be affected.
Read more about chickenpox on the NHS website.
UK NSC screening recommendation
Screening is not recommended because:
- there is very little data on susceptibility to chickenpox in the UK or on the number of susceptible women who come into contact with the virus during pregnancy
- current tests have not been evaluated for use in the general pregnant population
- there is no evidence looking at whether a screening programme improves the delivery of VZIG, so there is uncertainty on the benefit of a screening programme
