A estruturação do Sistema Nacional de Vigilância Epidemiológica do Brasil, em 1975, tornou obrigatória a notificação de algumas doenças transmissíveis com o objetivo de reduzir a carga destes eventos no país. Entretanto, as alterações no perfil epidemiológico destas doenças, associadas a características da sociedade contemporânea, determinam a constante adequação das atividades de vigilância a este cenário. Neste manuscrito, são descritos epidemiologia, tendências e diagnóstico diferencial das seguintes doenças dermatológicas de notificação compulsória no Brasil: aids, dengue, hanseníase, leishmaniose tegumentar americana, sarampo, rubéola e síndrome da rubéola congênita e sífilis. Também são apresentados os principais desafios atuais para o controle e prevenção para cada uma dessas doenças no BrasilThe development of a Brazilian National Surveillance System in 1975 led to a compulsory reporting of selected infectious diseases aiming to reduce the burden of these events in the country. However, shifts in the epidemiology of these diseases associated with modern life style, demand constant revision of surveillance activities. In this manuscript we present the epidemiology, trends and differential diagnosis of the following compulsory notifiable diseases in Brazil: Aids, dengue fever, hanseniasis, American tegumentary leishmaniasis, measles, rubella and congenital rubella syndrome and syphilis. Additionally, the current challenges for control and prevention of each disease are presented

Ten-valent pneumococcal conjugate vaccine (PCV10) was introduced in the National Immunization Program of Brazil in March/2010. Although there are recent reports of PCV10 impact on pneumonia hospitalizations, there is still uncertainty regarding the indirect impact in individuals non-targeted by vaccination. We assessed both direct and indirect effect of PCV10 on pneumonia hospitalizations and the impact on the economic burden of pneumonia hospitalizations.An interrupted time-series analysis was conducted considering monthly rates of pneumonia hospitalizations and comparison groups, in all age-groups, from January/2005-December/2015. We used records of the National Hospitalizations Information System. Observed pneumonia rates in the post-vaccination period (2011–2015) were compared to predicted rates, should PCV10 had not been introduced. Relative percent difference in rates and its 95% confidence interval were estimated. The number of pneumonia hospitalizations averted by vaccination was calculated as the difference between the predicted and observed cumulative number of pneumonia hospitalizations in the post-vaccination period. The impact of PCV10 on economic burden was presented as averted costs of pneumonia hospitalization.Significant decrease in rates of pneumonia hospitalization was observed in both children targeted by vaccination (17.4%–26.5%; p
