SUMMARY OBJECTIVE: The aim was to determine the epidemiological profile of dengue fever in Brazil between the years 2014 and 2019. METHODS: This is an observational, descriptive, cross-sectional, and retrospective study, which was carried out through the analysis of secondary data collected from the National System of Notification Appeals (SINAN) and from SUS Computer Department (DATASUS). RESULTS: The total number of reported cases was 5,867,255, and 2015 was the year with the highest cases (1,696,340). The cases were predominant in the Southeast and Midwest macro-regions, the female sex (55.6%), brown people (48%), and clinical and epidemiological criteria of confirmation (63.8%). Regarding the age group, it was observed that during the study period, the highest prevalence occurred in individuals between 20 and 39 years (38.3%). There was a change of serotype from DENV-1 to DENV-2, and dengue was the most prevalent classification (95.2%). Concerning hospitalization rates, there was a limited necessity of admissions (5.7%), as well as few deaths due to the notified disease (3,444). CONCLUSIONS: There was a significant growth in the number of dengue fever cases in Brazil in 2019, which represents a public health problem.
SUMMARY BACKGROUND To determine the epidemiological profile of measles in Brasil from 2013 to 2018, and to evaluate the possible association between increased number of cases and vaccination coverage. METHODS This is an observational, descriptive, cross-sectional, retrospective study with quantitative approach, carried out through analysis of secondary data collected through the Notifiable Diseases Information System (SINAN), in the National Immunization Program (PNI). RESULTS The total number of reported cases was 10,886, with the year 2018 having the highest number (10,185). In the North macro-region (93.4%), male (55.53%), autochthonous cases from the city of residence (94.42%) and laboratory confirmation (99.09%) predominated. Regarding the age group, it was observed that in the period from 2013 to 2015 the highest prevalence occurred in <1 year, with 44.5%, 40.6% and 29.0%, respectively, while in 2018, the highest rate was in the 20-29 age group with 24.2%. Vaccination coverage was below 95%, except for SCR - D1 (first dose of triple viral) in the years 2013 to 2016. Regarding the outcome, there was a limited number of deaths secondary to measles (0.12%). CONCLUSIONS There was an exponential growth in the number of measles cases in Brasil in 2018, which represents a public health problem. In view of this, it is necessary to implement measures such as broad vaccination coverage and sanitary control at the borders, in order to reduce the incidence of this disease and, consequently, the number of deaths.
RESUMO OBJETIVO Determinar o perfil epidemiológico do sarampo no Brasil no período de 2013 a 2018, além da possível correlação entre incidência de casos e cobertura vacinal. MÉTODO Trata-se uma pesquisa observacional, com delineamento descritivo, transversal, retrospectivo e com abordagem quantitativa, feita por meio de análises de dados secundários coletados no Sistema Nacional de Agravos de Notificação (Sinan), no Programa Nacional de Imunizações (PNI). RESULTADOS O total de casos confirmados foi 10.886, sendo o ano de 2018 com o maior número (10.185). Predominou a macrorregião Norte (93,4%), sexo masculino (55,53%), casos autóctones do município de residência (94,42%) e confirmação laboratorial (99,09%). Com relação à faixa etária, observou-se que, no período de 2013 a 2015, a maior prevalência ocorreu em <1 ano, com 44,5%, 40,6% e 29,0%, respectivamente, enquanto que, em 2018, o maior índice foi na faixa de 20-29 anos, com 24,2%. A cobertura vacinal ficou abaixo de 95%, exceto a SCR – D1 (primeira dose da tríplice viral) nos anos de 2013 a 2016. Quanto ao desfecho, houve limitado número de óbitos secundários ao sarampo (0,12%). CONCLUSÃO Verifica-se um crescimento exponencial no número de casos de sarampo no Brasil em 2018, o que representa um problema de saúde pública. Diante disso, carece que medidas como ampla cobertura vacinal e controle sanitário, nas fronteiras, sejam implementadas, a fim de reduzir a incidência dessa enfermidade e, consequentemente, o número de óbitos.
