Abstract
Objective: To describe the suspected cases of measles and rubella notified in the Notifiable Diseases Information System (Sinan), Brazil, from 2007 to 2016. Methods: Data were extracted from Sinan referring to the years 2007 to 2016. The variables used were the number of notifications of measles and rubella cases by region and year, age, gender, hospitalization, gestational status, vaccination history, vaccination blockade, serological collections (S1 and S2), signs and symptoms, adequate investigation, confirmation criteria or disposal and final case classification. Results: Between 2007 and 2016, there were 127.802 suspected cases of measles and rubella reported. Approximately 92% of cases were investigated, mostly in children under five years of age. The most frequent symptoms were cough (40%) and runny nose (38%). As a surveillance tool, blood was collected for laboratory confirmation in 87% of notifications. Most Measles cases occurred between 2011 and 2015, related to imported cases, totaling 1,443 cases; for Rubella 10,125 cases were confirmed. 1.3% (1,698/127,802) and 5.1% (6,555/127,802) of measles and rubella notifications, respectively, were discarded. 9.0% (11,523/127,802) for measles and 49% (62,978/127,802) for rubella were ignored. Conclusion: Surveillance of cases of exanthematous diseases allowed demonstrating the situation of cases of exanthematous diseases circulating in the country as an important public health tool. The large number of discarded cases classified as ignored deserves attention, in order to improve the closing of notified suspected cases.
