But researchers in the central Brazilian state of Sao Paulo now say that Zika may be more likely to produce a miscarriage than a baby with a smaller than normal head.

Because Fonseca had 1,125 pregnant women enrolled in the study, he could see that the rate of miscarriage nine out of canada goose outlet orlando 178 Zika positive mothers was far higher than among the women who never tested positive for the virus. There were only two spontaneous abortions among the 947 Zika negative women. So roughly five percent of the Zika positive mothers had miscarriages versus fewer than 0.2 percent of the canada goose outlet miami other women.

„I thought we’d find a lot of microcephaly but I wasn’t expecting such canada goose outlet black friday sale a high rate of miscarriages,” Dr. Fonseca said just before presenting his findings this week at the American Society of Tropical Medicine and Hygiene’s annual convention in Baltimore.
„It’s true that babies with microcephaly will have a big impact in terms of long term care.

He warns that these mothers are at increased risk for infections and that Zika could potentially lead to a rise in maternal mortality.
Canada Goose Jackets Albert Ko, a researcher from Yale who’s canada goose outlet us been studying the Zika outbreak in Northeast Brazil since it first emerged, says there may have been a canada goose womens outlet rash of Zika related miscarriages in the spring and early summer canada goose outlet online reviews of 2015 that went unnoticed.

When Zika first hit in early 2015, the symptoms of the disease were fairly mild. It wasn’t until nine months later when babies started being born with abnormally small heads that health canada goose outlet online uk officials and the public became concerned. If during that first wave of the outbreak, Zika was causing a spike in miscarriages, that spike would have occurred before the public alarm about the disease had been raised.
„That adverse outcome [miscarriage] of Zika infection, we probably missed it,” Ko says. „We probably missed it because we don’t have very good surveillance systems especially for women in the public sector health care system in Brazil.” Some women may have miscarried canada goose outlet belgium at home and not gone to a doctor. A miscarriage can also look like an induced abortion, which is illegal in Brazil, so that too could have led to an under reporting of the phenomenon.
