Answer:
1. It is a highly contagious disease transmitted from person to person and thereby it is expected that infected persons carried the virus to America
2. Microcephaly is a serious birth defect where a baby’s head is much smaller than expected.
3. Occipital bone. CNS malformations: ventriculomegaly, parenchymal and periventricular calcifications and cortical migration anomalies
Explanation:
The Zika virus (Flaviviridae) causes a contagious disease and it is transmitted by Aedes mosquitoes, which are also the main vectors of the dengue virus. Microcephaly is a condition where the baby’s brain has not developed properly during pregnancy, and it has been shown that this birth defect is associated with the Zika virus. During 2015 in Brazil, the incidence of infants with microcephaly born from mothers that contracted this disease during pregnancy was higher, thereby suggesting an association between both conditions. Baby health problems associated with Zika infection include microcephaly (skull partially collapsed), joints with limited motion, etc.
