PANORAMA CLÍNICO- EPIDEMIOLÓGICO DOS CASOS DE ZIKA VÍRUS NO MARANHÃO:ANÁLISE DOS ANOS DE 2018 A 2023

Arboviruses are endemic diseases and pose a significant challenge to public health. Among these arboviruses is the Zika virus, which can be transmitted by the bite of the Aedes aegypti mosquito and also via the placental route. This study aimed to evaluate Zika virus cases in the state of Maranhão between 2018 and 2023. This retrospective, descriptive, and quantitative study is based on secondary data provided by the System of Notifiable Diseases (SINAN) from the Department of Informatics of the Unified Health System (DATASUS). The study assessed reported cases of Zika virus in the Maranhão population from 2018 to 2023. The total number of confirmed Zika virus cases in Maranhão during this period was 5,831. The municipality of São Luís had the highest number of cases (n=2,573). The age group with the highest frequency of ZIKV cases was 20 to 39 years, accounting for 28.62% (n=1,668) of the cases. Most individuals had completed high school, representing 29.70% of the cases. The most frequent ethnicity in the sample was mixed race (parda), corresponding to 77.06% (n=4,462) of the cases. The sample was predominantly composed of female individuals (57.16%). The majority of cases received laboratory confirmation (75.66%), with an outcome of recovery (80.64%) (n=4,702), and without the presence of pregnancy (93.16%). In light of these findings, it can be inferred that further studies on the prevalence of ZIKV in the Maranhão population are extremely relevant for the development of public policies for vector control.  As arboviroses são doenças endêmicas e constituem um grande desafio para saúde pública. Dentre as arboviroses, tem-se o zika vírus, que pode ser transmitido pela picada do mosquito Aedes Aegypti e também por via placentária.O presente estudo teve como objetivo avaliar os casos de zika vírus, no estado do Maranhão, entre os anos de 2018 e 2023. A amostra avaliada trata-se de um estudo retrospectivo, descritivo e quantitativo, com base em dados secundários disponibilizados através do Sistema de Notificação de Agravos (SINAN), no Departamento de Informática do Sistema Único de Saúde (DATASUS). O estudo avaliou os casos notificados de Zika vírus na população maranhense, entre 2018 e 2023. O total de casos confirmados de zika vírus, no Maranhão, entre 2018 e 2023, foi de 5831.O município de São Luís foi aquele que apresentou maiores números de casos (n=2573). A faixa etária com maior frequência de casos de ZIKV foi a de 20 a 39 anos, correspondendo a um percentual de 28,62% (n=1668) dos casos. Os indivíduos, em sua maioria, apresentavam ensino médio completo, correspondendo a 29,70%. A cor/ raça mais frequente, na amostra analisada, foi a parda correspondendo a 77,06% (n=4462) dos casos. A amostra foi composta majoritariamente por indivíduos do sexo feminino (57,16% ). A maioria dos casos recebeu confirmação laboratorial (75,66%), com evolução para cura (80,64%) (n=4702)  e sem a presença de gravidez, (93,16%). Diante do exposto pode-se inferir que o desenvolvimento de mais estudos acerca da prevalência do ZIKV na população maranhense é extremamente relevante para o desenvolvimento de políticas públicas de controle de vetores.&nbsp

Neotropical freshwater fisheries : A dataset of occurrence and abundance of freshwater fishes in the Neotropics

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.
