“…Surveillance data presented in this study represents all notified cases, included those probably not caused by enterovirus, since other causative agents are not uncommon in our country, such as Leptospira sp., dengue virus, Bartonella sp. and Herpes simplex virus [2,11,19]. Epidemiological data about the etiological agents responsible for AM in Rio de Janeiro are largely unknown, so the real extension of enterovirus involvement in cases of AM in our setting is an unresolved question.…”

Echovirus 30 belongs to the genus Enterovirus and is widely associated with aseptic meningitis (AM) outbreaks. In Brazil epidemics due to this serotype were reported in several states but in Rio de Janeiro, before this study, it was only involved in sporadic episodes. We retrospectively collected data from AM notifications charts and enterovirus isolation database from Rio de Janeiro State Health Department (RJSHD) and Enterovirus Reference Laboratory in the year of 2005. An outbreak of AM was detected during March, April and May associated with a high cell culture isolation rate for echovirus 30 (17.4%). Male children with ages varying from 1 to 9 years were more affected. Of the 22 patients with confirmed echovirus 30 disease, clinical information was available in eight; fever, headache and vomiting were the most common manifestations. CSF analysis showed a typical pattern of viral infection with median of cellularity of 100 cells/mm(3) and mononuclear cell predominance in 64.7% of the cases. The median of protein and glucose levels of 49 mg/dL and 56.5 mg/dL. The fatality rate was null. Despite its benign course and the lack of treatment options, aseptic meningitis surveillance is crucial for early identification of causative agents of outbreaks, which helps to avoid additional testing and inappropriate use of antimicrobials.

“…A espécie L. interrogans tem vários sorovares e, no Brasil, o sorovar icterohaemorrahagiae parece ser o mais comum. Em Recife, Salvador e São Paulo este sorovar foi identificado como agente causal em mais de 50,0% dos casos descritos 21 . Romero et al 22 …”

O objetivo deste trabalho foi verificar a ocorrência de infecção por Leptospira spp. em cães errantes de Itapema, Santa Catarina, Brasil. As amostras de soro coletadas em 590 cães de rua foram testadas contra 25 sorovares de Leptospira spp. usando-se o teste de soro aglutinação microscópica. A ocorrência de anticorpos antileptospiras para um ou mais sorovares foi de 10,5%. O sorovar mais freqüente foi pyrogenes com 26 (18,0%) amostras positivas, seguido pelos sorovares canicola 20 (13,8%), icterohaemorragiae e copenhageni com 18 (12,5%), com títulos de anticorpos variando de 1:100 a 1:3.200. Considerável prevalência (10,4-11,1%) também foi detectada para os sorovares castellonis, butembo e grippothyphosa.

“…For example, several studies have been conducted in Brazil and other parts of the world, using different geographical scales, producing distinct results. Most of the research has been done in urban areas, mainly slums, followed by rural and wilderness areas [ 2 , 3 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ].…”

Leptospirosis displays a great diversity of routes of exposure, reservoirs, etiologic agents, and clinical symptoms. It occurs almost worldwide but its pattern of transmission varies depending where it happens. Climate change may increase the number of cases, especially in developing countries, like Brazil. Spatial analysis studies of leptospirosis have highlighted the importance of socioeconomic and environmental context. Hence, the choice of the geographical scale and unit of analysis used in the studies is pivotal, because it restricts the indicators available for the analysis and may bias the results. In this study, we evaluated which environmental and socioeconomic factors, typically used to characterize the risks of leptospirosis transmission, are more relevant at different geographical scales (i.e., regional, municipal, and local). Geographic Information Systems were used for data analysis. Correlations between leptospirosis incidence and OPEN ACCESS Int. J. Environ. Res. Public Health 2014, 1110367 several socioeconomic and environmental indicators were calculated at different geographical scales. At the regional scale, the strongest correlations were observed between leptospirosis incidence and the amount of people living in slums, or the percent of the area densely urbanized. At the municipal scale, there were no significant correlations. At the local level, the percent of the area prone to flooding best correlated with leptospirosis incidence.
