Risk of Zika virus higher than first thought: Scientists
May 2, Brasilia: The mosquito-borne Zika virus may be even more dangerous than previously thought. Scientists have said that Zika could be behind more damaging neurological conditions, affecting the babies of up to a fifth of infected pregnant women.
Rates of increase in Zika infection in some parts of Brazil have slowed, thanks to better information about preventing the disease. But the search for a vaccine is still in the early stages, media reports said.
Most doctors and medical researchers now agree that there is a link between the Zika virus and microcephaly, where babies are born with abnormally small heads because of restricted brain development, BBC reported.
It is estimated that one percent of women who have had Zika during pregnancy will have a child with microcephaly, leading doctors in Brazil have told the BBC that as many as 20 percent of Zika-affected pregnancies will result in a range of other forms of brain damage to the baby in the womb.
A separate study, reported in the New England Journal of Medicine, said that "29 percent of scans showed abnormalities in babies in the womb, including growth restrictions, in women infected with Zika".
