Zika New study finds some serious consequences for pregnant women
#Cosmoread: Zika virus, some pregnant women do not fare well, and neither do their fetus, a new study suggests.
Zika is a mosquito-borne virus which can be transmitted through unprotected sexual intercourse. Because of concerns that the disease microcephaly (small brain size) and virus-infected pregnant women can increase the risk of developmental disorders in embryos, the scientists of both healthy and infected pregnant women have decided to keep an eye on.
The researchers studied 88 pregnant women in Rio de Janeiro from September 2015 through February 2016, the study, published Friday (4 March), according to the New England Journal of Medicine. 72 of these women, their blood, urine, or both tested positive for Zika virus.
Zika between positive pregnant women, the most common symptoms, rash, joint pain, red eye and were headache, the researchers found. Doctors also Zika in women with and 42 women without the fetal ultrasound performed at all. Zika positive group them (29 percent) 12 16 Zika negative women with fetal abnormalities were compared by some.
12 fetuses with abnormalities in addition to the two of them were killed – 36 weeks and 38 weeks in the other. Five embryos were smaller than usual (and some had microcephaly), seven had lesions of the central nervous system, brain or umbilical artery and seven amniotic fluid or an unusual amount of flow, the researchers said. Microcephaly and other challenges of a fetus brain development, growth restriction and had additional problems, including a potential clubfoot, he said.
To date, eight of the 42 women who have given birth in ultrasound, and ultrasonographic findings are confirmed, the researchers said.
“Despite the slight clinical symptoms, Zika virus infection during pregnancy fetal death, placental insufficiency, fetal growth restriction and grave consequences, including injuries to the central nervous system appears to be associated with,” scientists in the study said.
The findings “very disturbing,” Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases reporters March 10.
Given that fetal abnormalities were found in 29 percent of Zika positive women, it may not be possible, “many more [abnormalities] that you do not realize until after the baby is born,” Fauci said.
In addition, the study shows that embryonic developmental problems even when their mothers late in their pregnancies had caught the disease.
“All the three trimesters of pregnancy, there were certain fetal effects,” Dr. Tom Frieden, director of the Center for Disease Control and Prevention told reporters the talks today. “What we are basically saying that the more we learn about Zika in pregnancy, the more concerned we are.”
