Ministry also released the microcephaly numbers in the country, which already amount to 1,761 notifications

Not only microcephaly is a threat to pregnant women and children exposed to the virus zika. Women infected with the disease during pregnancy are also at higher risk for miscarriage or babies born dead (stillborn). The warning was given yesterday by the Ministry of Health (MOH) during the launch of the "Surveillance Protocol and response to occurrence of microcephaly Related to infection Zika virus" in Brasilia, which also updated data on the occurrence of malformation in the country. There are already 1,761 suspected cases of the anomaly, 477 more cases in a week. Pernambuco continues with the highest number of notifications: 804.

The head of the Department of Communicable Disease Surveillance (DEVIT) of the Ministry of Health, Claudio Maierovitch, stressed that research on abortion and stillbirth is new between the protocols already in place at the federal or state level. "To date, we have not had official notification to MS on the increase of abortions, but with that protocol, of course, we will begin to see that," he said.

The doctor and head of childhood infectious diseases at the University Hospital Oswaldo Cruz (HUOC), Angela Rocha, said he has heard reports of women who lost babies after viral episodes with rash (red spots on the skin), but there is still no numbers attesting that the increase occurring in Pernambuco. However, this is more of a risk to be considered at the time to get pregnant.

"This (abortion) can happen with many other viruses, not only zika, especially if the mother falls ill in early pregnancy. Depending on the mother's defense system and other factors, this infection can lead to some defects in the fetus's structure, serious injury, and that end up being incompatible with the course of pregnancy, leading to miscarriage. It's a risk, yes, "he said.

The infectious disease also pointed out that other factors to be considered for abortion are problems in placental composition and the trend of women having previous episodes of abortion. Already suspicious deaths microcephaly in children who were born and died then now total 19 across Brazil. Most of the records were in Rio Grande do Norte (RN), which adds seven deaths.

According to the infectious disease specialist and professor, Kleber Light, so far those tests babies tested negative for various viruses, such as rubella, cytomegalovirus and toxoplasmosis. This reinforces the thesis infection zika. All potiguares mothers who lost their children had rashes during pregnancy.


PROTOCOL - The Surveillance and Response Protocol to the occurrence of microcephaly Related to Zika virus infection increases the case definitions for identification during pregnancy and postpartum. Now, to ascertain detection: pregnant women with possible infection zika virus; fetus with alterations of the central nervous system, possibly related to infection during pregnancy; miscarriage due to possible association with the virus; stillborn after possible infection zika; and live newborn (RNV) with microcephaly possibly associated with infection during pregnancy.


The Graduate Teacher vision in Environmental Management at the Faculty of Guararapes, Luis Cometti, the large presence of the Aedes aegypti may also explain the increasing curve of cases of malformation, but it is not the only factor. "Consumption of products with pesticides, for example, which is great in Pernambuco, may be a reason," he explains, adding that conditions of cities, which, in the Northeast, have historical infrastructure deficiencies also contribute to the setting.
