Data from research conducted in Paraíba by the Ministry of Health and the CDC from the USA.  According to the new bulletin, 4,046 cases are under investigation for microcephaly, 1,046 have been confirmed and 1,814 discarded.

The control case study carried out in Paraíba shows, preliminarily, that mothers who have had Zika virus in the initial three months of pregnancy presented higher probability to have children with microcephaly.  The Ministry of Health, in partnership with the Government of Paraíba and the Centers for Disease Control and Prevention (CDC) of the United States, continues the analysis of blood samples collected from the mothers and babies from Paraíba. Only after this phase, the final results will be announced. The initial result of the study, presented in João Pessoa (PB), has also found no association of microcephaly with exposure to products such as insecticides, for example.

"The investigation of people who have not been affected by microcephaly is part of the study.  Only after processing the collected blood samples, comparing cases and controls, we will be able to estimate more clearly the risk of being affected by the disease and Zika's relationship with microcephaly", said the adviser of the Surveillance Secretariat in Health of the Ministry of Health, Eduardo Hage, highlighting the commitment of the teams in the field phase of the research. "The study was conducted in an agile, ethical and effective manner. The teams have taken important steps in the search for answers to the problem that concerns the world", the Secretary of Health Surveillance, from the Ministry of Health, Antonio Nardi, added.

The research, which began on 22 February, featured the work of eight teams - composed by the institutions involved - that investigated the proportion of infants born with Zika-associated microcephaly, in addition to the risk of virus infection in 56 municipalities of the state. Overall, 165 cases of mothers who had babies with microcephaly were interviewed, and 446 control (mothers and babies in the same area without microcephaly). Among the babies, 52% are female and 48% male, in the age group from 0 to 7 months.

NEW RELEASE - All over Brazil, 4,046 suspected cases of microcephaly are under investigation, according to a new report released on Tuesday (5) by the Ministry of Health. Since the beginning of the investigations, in October 2015, until April 2 - there were 6,906 notifications in 1,307 municipalities in all federative units. Out of completed cases, 1,814 have been discarded and 1,046 were confirmed to microcephaly and other nervous system disorders, suggestive of congenital infection.

Out of these, 170 have already had laboratory confirmation for the Zika virus.   In those cases, specific lab tests for Zika virus have been done.  However, the Ministry of Health highlights that this data does not represent, properly, the total number of cases related to the virus.  That is, it is considered that there has been infection through Zika for most mothers who have had babies with a final diagnosis of microcephaly.

Up to Abril 2, 227 deaths were registered (fetal or neonatal) with suspected microcephaly and/or alterations in the central nervous system after delivery or during pregnancy (abortion or stillbirth).  Out of these, 51 were confirmed to microcephaly and/or alteration of the central nervous system.  The other 148 are still under investigation and 28 have been discarded.

It should be noted that the Ministry of Health is investigating all cases of microcephaly and other central nervous system disorders, informed by the states, and the possible relationship with the Zika virus and other congenital infections. Microcephaly may be caused by various infectious agents in addition to Zika, as Syphilis, Toxoplasmosis, other infectious agents, Rubella, Cytomegalovirus and Viral Herpes

The Ministry of Health advises pregnant women to adopt measures to reduce the presence of the Aedes aegypti mosquito, with the elimination of breeding sites, and to protect themselves from the mosquito exposure, keeping doors and windows closed or screened, wearing pants and long-sleeved shirts and using repellents allowed for pregnant women.

RESEARCH - Another study carried out by a research group about Zika epidemics (MERG) has pointed out that out of 100 mothers of children with microcephaly interviewed in the state of Pernambuco, 59 noticed the presence of exanthema (skin rash) during pregnancy, a common symptom in people infected by the zika virus.  The research was published in a scientific journal of the Centers for Disease Control and Prevention (CDC), United States.

Among the members of this group are specialists of the Osvaldo Cruz Foundation Pernambuco - Aggeu Magalhães  Research Center (Fiocruz/CPqAM), from the Pan American Health Organization/ the World Health Organization (PAHO/WHO), from the Ministry of Health,  from Professor Fernando Figueira Integral Medicine Institute (IMIP), from the Federal University of Pernambuco, the Federal University of Rio Grande do Sul, from the State Health Secretariat of Pernambuco, the Federal University of Fronteira Sul, from the University of Pernambuco, from the Institute for Health Technology Assessment, and from the London School of Hygiene & Tropical Medicine.
