My brother is affected with chickenpox. Will my pregnant wife get the infection soon?

Hello,

Welcome to icliniq.com.

I have seen the report. (attachment removed to protect patient identity). I can understand your concern. I will answer one by one.

As you told me it is 8th week I would like to tell you that in the first 12 weeks the overall risk of transmitting infection to the child and development of severe disease in child is only 0.4 percent. In your case, the mother already has protective antibodies (IgG antibodies), cutting down the risk further. But still, we do not want to risk the child whatever risk may be. So I will advise for isolation of mother or patient until all the lesions of chickenpox get crusted because after they crust, they get noninfectious. The chance of getting chickenpox again in life is a rare phenomenon but at times if the immunity is low it may occur.

Equivocal in the report means that the mother has protecting immunity against chickenpox but not very strong. It would be strong if the levels were more than 12 but it is not negative. That means the mother can fight some infection. It is not very bad to get affected at this stage, but if it happens near the delivery time or within five days of delivery then it is very bad. Right now, even if she gets infected, she will develop immunity and pass on to the baby. Some antiviral drugs can be given if infected, but I do not think she requires it now. And yes definitely, until the infective stage of your brother and sister vanishes you should think of isolation.
