The Zika virus may stop brain development causing microcephaly and birth defects

mosquito_3DWhen a woman is pregnant and is infected with the Zika virus, it may cross the placenta and may stop the development of a baby’s brain. Zika infection during pregnancy causes a birth defect called microcephaly as well as other brain problems known as “fetal brain disruption sequence.”

Microcephaly means small (micro) head (cephaly) – a baby’s head is smaller than the heads of babies of the same age and sex. Microcephaly does not always cause serious problems for a baby. But in certain cases, microcephaly can cause lasting consequences, such as intellectual and developmental disabilities. Babies born with microcephaly may have cerebral palsy, poor growth, face deformities, feeding problems, seizures, problems with hearing or vision, and hyperactivity. They may face life-threatening medical conditions. Microcephaly caused by the Zika virus may be severe and is extremely concerning.

There is no cure for microcephaly. Babies with microcephaly will need regular medical check-ups and follow up care. Many will need specialized treatment by doctors such as a neurologist, developmental and behavioral pediatrician, and rehabilitation specialists. Early intervention services for babies and toddlers as well as special education services for children ages 3 and older, may be essential in helping a child develop.

Fetal brain disruption sequence refers to the halting of the development of a baby’s brain as a result of being exposed to the Zika virus. This stop in development can result in a wide variety of health problems for the baby, which can be lifelong.

The Zika virus may also be linked to growth problems in the womb, miscarriage and stillbirth.

Vaccine progress

Currently, there are no FDA-approved vaccines to prevent Zika. But, the FDA (The US Food and Drug Administration) has approved the first Zika vaccine study in human volunteers, ahead of schedule. Clinical trials should begin in the next few weeks. Although this is great news, it could take years before a safe vaccine is available to the public.

How can you stay safe?

The Zika virus is real and dangerous. Until a vaccine is available, learn all you can about how to stay safe.
