Zika: Risk higher than first thought, say experts
The mosquito-borne Zika virus may be even more dangerous than previously thought, scientists in Brazil say. Leading doctors have told the
BBC that Zika could be behind more damaging neurological conditions, affecting one in five pregnant women who contract it.
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. And Zika continues to spread across the region. 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.
While it is estimated that one per cent of women who have had Zika during pregnancy will have a child with microcephaly, doctors in Brazil have told the BBC that as many as 20 per cent 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 per cent of scans showed abnormalities in babies in the womb, including growth restrictions, in women infected with Zika”.
