Evidence of Zika’s risk to pregnant women continues to grow
06 March 2016, Nirapad News: Researchers report that the Zika virus may be linked to a wider variety of “grave outcomes” for developing babies than previously reported — threats that can come at any stage of pregnancy.
The findings released Friday are preliminary results from the first study tracking pregnant women in Brazil from the time they were infected, and do not prove that Zika is to blame. But they come as separate laboratory research released Friday strengthens the case that Zika causes a serious birth defect called microcephaly — babies born with abnormally small heads — by targeting embryonic brain cells. “It’s much more than microcephaly,” said Dr. Karin Nielsen of the University of California, Los Angeles, who led the pregnancy study with colleagues at the Fiocruz Institute in Brazil. “It seems like it can act on multiple fronts.”
The mosquito-borne virus, which is spreading in Latin America and the Caribbean, normally causes only mild symptoms, if any, in adults. But it raised alarm when Brazilian health officials reported an apparent surge in babies born with microcephaly, which can signal their brains didn’t develop properly. Reports have documented traces of the virus in the brains of affected babies who died soon after birth, and in fetal brain tissue after abortion.
