[Knowledge and practices in Aedes aegypti control among different social subjects in Salvador, Bahia State, Brazil].

Due to the persistence of dengue and other arbovirus infections in Brazil, the government has stepped up measures to combat the Aedes aegypti mosquito vector. The responsibilities of community endemic disease workers (CEDW) and community health workers (CHW) include acting as intermediaries and disseminating knowledge in the community. The aim of this study was to analyze knowledge and practices in dengue control by different social subjects: residents and CEDW/CHW. Interviews were held with residents, field and mobilization CEDW, and CHW in two neighborhoods in Salvador, Bahia State, using focus groups. Residents expressed uncertainty on the form of transmission and hazards of dengue. Field CEDW voiced conflicting feelings due to the need to inform the community on issues over which they lack any control, while expressing personal dissatisfaction with their work and a feeling of underappreciation due to their lack of training. Mobilization CEDW blamed the population and emphasized their own importance as the solution to dengue control. CHW failed to reflect their field experience in their discourse and felt they had no responsibility over vector control. All the groups agreed that government is to blame for dengue and that the solution lies in education. There is an evident need for regular educational interventions, based on dialogue and awareness-raising to deal with residents' daily reality, drawing individuals (residents and CHW) into the knowledge-building process. Under the prevailing methodology, the dissemination of information and knowledge is insufficient to promote community improvements for dengue control.

[Incidence and risk factors for congenital syphilis in Belo Horizonte, Minas Gerais, 2001-2008].

Congenital syphilis continues to be a public health problem in Brazil. The scope of this study is to describe the trends in the incidence of congenital syphilis in Belo Horizonte between 2001 and 2008 and determine risk factors associated with disease diagnosis. Data on cases of congenital syphilis and on the population of live births were obtained from the National Notifiable Diseases Information System (SINAN) and from the National Live Birth Information System (SINASC), respectively. Multivariate logistic regression analysis used the population of live births as the reference group to identify independent risk factors for congenital syphilis. The annual incidence of congenital syphilis revealed a rising trend from 0.9 to 1.6 cases per 1,000 live births between 2001 and 2008. Independent risk factors for congenital syphilis included: maternal schooling <8 years (OR: 1,3; 95% CI: 1,2-1,4); black or mixed maternal race (2,1; 1,5-2,8) and lack of antenatal care (11,4; 8,5-15,4). The strong association between the lack of antenatal care and congenital syphilis indicates that universalization of antenatal care is critical for the control of congenital syphilis. The effective control of the disease in Brazil will depend on actions to reduce social inequities in health.

Burden of group A streptococcal meningitis in Salvador, Brazil: report of 11 years of population-based surveillance.

Background: Over recent decades, a resurgence of invasive group A streptococcal (GAS) infections has been observed; GAS remains a rare cause of pyogenic meningitis. We report herein population-based findings of long-term surveillance for GAS meningitis in Salvador, Brazil, and estimate the overall burden of invasive GAS infections.

Methods: From February 1996 to February 2007 we conducted active surveillance for GAS meningitis in the state reference hospital for infectious diseases in Salvador, Brazil. Data on clinical presentation, laboratory records, and outcome were collected through interviews and chart review. GAS isolates were evaluated for antimicrobial susceptibility and emm type.

Results: We identified 20 cases of GAS meningitis, which accounted for 0.9% of all culture-proven bacterial meningitis in the study period. The mean annual incidence of GAS meningitis was 0.03 cases per 100,000 population in metropolitan Salvador and peaked in children <1 year of age (0.67 cases per 100,000 population). Among 17 cases with clinical information available, 41% required intensive care unit support and 25% died. Tested isolates were susceptible to penicillin and exhibited large emm type diversity. Based on the incidence of GAS meningitis, we estimate that the annual incidence of GAS infection is 3 cases per 100,000 population in metropolitan Salvador.

Conclusions: Although rare, GAS is a life-threatening cause of bacterial meningitis. Knowledge of the incidence and emm type variability of the disease is necessary for planning immunization strategies.
