Research shows that: the fetal brain damage than Zika microcephaly — technology — people currently on Zika virus mainly concerns may cause neonatal microcephaly, and researchers in Brazil and the United States 23 report that they use imaging technology reveals Zika virus damage to the fetal brain, showed the damage was more serious than previously thought. With the help of fetal magnetic resonance imaging, neonatal brain tomography and ultrasonic technology, the study published in the new issue of the United States "on the" radiology of 45 Brazil fetus or baby, of which 17 people confirmed infected Zika virus, 28 people suspected of Zika virus infection. The results showed that they have a series of brain abnormalities, except for microcephaly, including brain gray and white matter volume decreased, abnormal ventricular dilatation and brainstem. The researchers said, almost all the subjects appeared ventriculomegaly, although 3 fetal head circumference normal, but that is the result of the expansion of severe ventricle; most of the research object are corpus callosum abnormalities, the corpus callosum is connected with left and right hemispheres of the nerve fibers, most communication between the hemispheres is through the corpus callosum the. The results showed that in addition to a baby, all of the subjects had abnormal problem which means that cortical migration, the destination right transfer to the brain and neurons can not; almost all infants have intracranial calcification problems. Because all the baby have reduced brain volume, all cerebral cortex development are abnormal problems of different degree, some researchers worry that the infection of Zika virus at birth but seemingly normal babies may appear with the development of brain injury. The study, conducted by the University of Fed Rio De Janeiro and the Harvard University, also confirmed that women are most likely to be infected with the disease in the first 3 months of pregnancy and are most likely to cause severe brain defects in their babies. The virus is mainly spread through mosquito bites, and sexual behavior is also a way of transmission. Most of them have mild symptoms, and there is no effective treatment and vaccine for the disease.
