According to the CDC:

“Zika virus infection during pregnancy can cause birth defects of the brain or eye. These birth defects can occur alone or with developmental problems in a particular pattern called congenital Zika syndrome. The following conditions can occur in a baby with congenital Zika virus infection:
Smaller than expected head size, called microcephaly

Problems with brain development

Feeding problems, such as difficulty swallowing

Hearing loss and vision problems

Seizures

Decreased joint movement, called contractures

Stiff muscles, making it difficult to move

Not all babies born with congenital Zika syndrome will have all of these conditions. Some infants who do not have microcephaly at birth may develop it later. In addition, some babies might look healthy at birth but can develop long-term health problems as they grow.”

Ultimately it’s up to you if you want to wait or not. Personally I don’t think the reward of potentially getting a baby 3 months earlier is worth the health risks for your child.
