"It's part of this study to investigate people who were not affected by microcephaly. Only after processing the collected blood samples, comparing cases and controls, can we estimate more clearly the risk of being affected by the disease and Zika's relationship with microcephaly, "said the aide Surveillance Secretariat of Health the Ministry of Health, Eduardo Hage, highlighting the commitment of the teams in the field phase of the research. "The study gave 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, Ministry of Health, Antonio Nardi.
