Brazil MOH: Epi Week 10 Microcephaly Report







#11,155


The Brazilian MOH hasn't posted an English language version yet, but thanks to Greg Folker's tweet, we have a link to a PDF version (albeit, in Portuguese).  Some translated snippets (and my comparison to last week) follow.


EPIDEMIOLOGICAL BULLETIN # 17 - EPIDEMIOLOGICAL WEEK (IF) 10/2016 (05/03 A 3/12/2016) MONITORING OF MICROCEPHALY CASES IN BRAZIL

This document contains the epidemiological information related to microcephaly and / or changes in the CNS, provided for in the existing definitions in the "Surveillance and Response Protocol to the microcephaly of occurrence and / or changes in the Central Nervous System (CNS) - Version 2/2016" available in www.saude.gov.br/svs site. The overall objective of this monitoring is to describe the epidemiological pattern of occurrence of microcefalias related to congenital infections in the country.

I - MICROCEFALIAS SURVEILLANCE AND / OR CHANGES OF THE CENTRAL NERVOUS SYSTEM (CNS)
1. General information
Until March 12, 2016 (SE 10), 6,398 cases were reported, according to the surveillance protocol settings (newborn, stillbirth, abortion or fetus). Of these, 4,201 (65.7%) cases remain under investigation and 2,197 cases were investigated and classified, with 854 confirmed for microcephaly and / or abnormal CNS suggestive of congenital infection and 1,343 dropped (Table 1).


Although the number of cases under investigation decreased by 30 this week (to 4201), the overall number of suspected cases increased by 240.

Last week 109 microcephaly cases were confirmed, and 161 previously suspected cases were discarded, which effectively removed 270 cases from the investigational pool.
This was a much larger weekly clearance rate than we've seen before. The report also notes:

Information on cases that have evolved to stillbirth or neonatal
Of the reported cases, 182 (2.8%) total of 6,398 cases have progressed to fetal or neonatal death. Of the 182 fetal or neonatal deaths reported, 124 (68.1%) remain under investigation, 40 (22%) were confirmed to microcephaly and / or abnormal CNS suggestive of congenital infection and 18 (9.9%) were discarded (Table 3).
