In the bulletins, the total cumulative number of reported microcephaly cases are classified as being 1) under investigation (investigation not completed), 2) confirmed (by neuroimaging and/or laboratory testing), or 3) excluded (investigation with negative results); and among confirmed cases, whether or not they were associated with Zika virus infection during pregnancy (positive RT-PCR and/or serology for Zika virus in the mother and/or newborn). The incidence of microcephaly per 10,000 live births in Brazil and regionally was calculated from the beginning of the outbreak to December 2016 and then stratified in the periods before and after July 2, 2016. Since the beginning of the outbreak of microcephaly in November 2015, 23.6% of cases (2566/10,867) were reported in the second half of 2016 (EW27-52); from these, 40% (n = 1026) occurred in the Southeast region, and 36.8% (n = 944) in the Northeast region (Table 1). A marked decline occurred in the Northeast region from 25.4 to 8.9, while the incidence doubled in the Southeast (1.4 vs. 3.1), Midwest (3.4 vs. 7.2), and South (0.4 vs. 0.8) regions (Table 1). Since EW 11 in March, the reported cases of microcephaly had dropped to lesser than 150 cases per week. Nº of REPORTED cases of Zika virus infection Estimated number of inhabitantsa Incidence...
