67 Cases of microcephaly were already related to the Zika virus

Suspicious cases of microcephaly under investigation by the Ministry of Health and the states reach 4,107 across the country. The numbers are part of the Epidemiological Report of Microcephaly, released on Tuesday (23). The bulletin also indicates that 950 reports have already been discarded and 583 confirmed for microcephaly and other nervous system disorders, suggestive of congenital infection.

Of the total confirmed cases, 67 were notified by specific laboratory criteria for the Zika virus. However, the Ministry of Health points out that this figure does not adequately represent the total number of cases related to the virus. The folder considers that there was infection by Zika in the majority of mothers who had babies, whose final diagnosis was microcephaly.

It should be clarified that the Ministry of Health is investigating all cases of microcephaly and other central nervous system disorders, reported by the states and the possible relationship with the Zika virus and other congenital infections. Microcapnia may be caused by a number of infectious agents other than Zika, such as syphilis, toxoplasmosis, rubella, cytomegalovirus, viral herpes, and other infectious agents.

The 583 confirmed cases occurred in 235 municipalities located in 16 states: Alagoas, Bahia, Ceará, Maranhão, Rondônia, Espírito Santo, Goiás, Mato Grosso do Sul, Pará, Paraíba, Pernambuco, Piauí, Rio Grande do Norte, Goiás, Rio de Janeiro and Rio Grande do Sul. The 950 cases were discarded because they presented or the presence of microcephaly and / or changes in the central nervous system due to non-infectious causes.

The 4,107 cases under investigation represent 72.8% of the cumulative total of 5,640 cases reported since the initiation of the investigations on 22 October 2015 until February 20, 2016. The total notified is distributed in 1,101 municipalities of 25 units of the federation. Amapá and Amazonas are the only states of the federation that do not have any case records.

In all, 120 deaths due to microcephaly and / or central nervous system alteration after delivery (stillbirth) or during pregnancy (abortion or stillbirth). Of these, 30 were confirmed for microcephaly and / or central nervous system alteration. Another 80 are still under investigation and 10 have already been discarded.

To date, Zika virus has circulated with 22 units of the federation autochthonous. They are: Goiás, Minas Gerais, Federal District, Mato Grosso do Sul, Roraima, Amazonas, Pará, Rondônia, Mato Grosso, Tocantins, Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Bahia, Espírito Santo , Rio de Janeiro, São Paulo and Paraná. In the last few days, the Ministry of Health announced that, starting with Epidemiological Report No. 13 (released on February 17), the Ministry of Health announced that it had confirmed the transmission of the virus in 29 countries in the Americas.

Controversy with data

"will begin to disclose these confirmed cases without specifying the laboratory diagnosis for Zika virus, since these data do not adequately represent the number of cases observed (magnitude). In addition, from that moment, it will consider that all confirmed cases are related to infection congenital by the Zika virus. " Also according to this report: "a very small proportion of these cases, after follow-up and specific analyzes, is confirmed for other causes, but so few are children that this does not change the assessment of the trend (increase or decrease) in the number of cases (magnitude). "However, the reporter and columnist of Folha de S.Paulo newspaper Cláudia Collucci wrote on Tuesday (23) in her column an ​​open letter to WHO Director-General Margaret Chan, denouncing the absurdity of this "achism" of the Ministry of Health, which brings even more mystery and misinformation about the relationship between microcephaly and Zika virus.Thereafter, in the Epidemiological Bulletin today (23), the Ministry of Health again released the numbers of cases in which the relationship with the Zika virus was confirmed, although it is pointed out that "this figure does not adequately represent the total number of cases related to the virus.The folder considers that there was infection by Zika in the majority of the mothers who had babies, whose final diagnosis was microcephaly.
