viruses like Zika exist exhorting damaged fetus according to a report conducted by the scientists. Contamination with two associated viruses also germinates fetal defects in mice. Some scientists have conjectured that Zika’s capability to mistreat a fetus might be one of its kind may be because of contemporary alteration in the virus’s genetic material. Some debate that this menacing ability was always prevalent. It was only in 2015 – 16 infestation in the Western Hemisphere that adequate pregnant women that got infected were affected for public health researchers to discover the relationship with fetal defects.
But recent work advocates this capability is not Zika’s alone. Pregnant mice infected with West Nile or Powassan virus — both flaviviruses, like Zika — also showed fetal harm. More than 40 percent of these fetuses succumbed to death. However, among the pregnant mice which were infected from one of the other two viruses other than Zika, survived. George Saade, an obstetrician-gynecologist and cell biologist at the University of Texas Medical Branch at Galveston said that numerous viruses involving that of Zika can contaminate the placenta and cells of the baby. This is an ever increasing phenomenon and underscores the risks from viruses with which we are not familiar.
Viruses, West Nile virus and Powassan virus are neurotropic meaning these pathogens target nerve cells. Both viruses can pose inflammation of brains or membranes surrounding the brain. West Nile is imparted to humans by mosquitoes that have bitten contaminated birds.
