摘要

Adult forms of lepidopterans can cause health problems. This type of incident is known as Lepidopterism, which is caused by contact with urticating setae released by adults, such as those from the Hylesia Hübner (Saturniidae) genus. In this study, the objective is to document a new occurrence of lepidopterism caused by specimens of Hylesia nigricans(Berg, 1875) (Lepidoptera: Saturniidae). The outbreak took place in the summer of 2017 in the municipality of Três Coroas, Rio Grande do Sul, Brazil. During this period, approximately 300 people were affected by dermatitis in the municipality.The outbreak resulted from the release of two types of urticating setae by female moths in the area. We want to emphasize that in case of proliferation of this moth species, it is essential to instruct the population to avoid direct contact with these insects. Monitoring these groups of lepidopterans is fundamental in facilitating decision-making and ensuring public health. (AU)

Neste estudo, o objetivo é registrar uma nova ocorrência de lepidopterismo causado por espécimes de Hylesia nigricans (Berg, 1875) (Lepidoptera: Saturniidae). O surto ocorreu no verão de 2017, no município de Três Coroas, Rio Grande do Sul, Brasil. No período, aproximadamente 300 pessoas foram acometidas por dermatite no município. O surto foi causado pela liberação de dois tipos de setas urticantes das mariposas fêmeas no ambiente. Ressaltamos que na ocorrência da proliferação dessa espécie de mariposa, é importante instruir a população a evitar o contato direto com esses insetos. O monitoramento desses grupos de lepidópteros é fundamental para facilitar a tomada de decisões e garantir a saúde pública. (AU)

摘要

BACKGROUND In Brazil, the yellow fever virus (YFV) is maintained in a sylvatic cycle involving wild mosquitoes and non-human primates (NHPs). The virus is endemic to the Amazon region; however, waves of epidemic expansion reaching other Brazilian states sporadically occur, eventually causing spillovers to humans. OBJECTIVES To report a surveillance effort that led to the first confirmation of YFV in NHPs in the state of Minas Gerais (MG), Southeast region, in 2021. METHODS A surveillance network was created, encompassing the technology of smartphone applications and coordinated actions of several research institutions and health services to monitor and investigate NHP epizootics. FINDINGS When alerts were spread through the network, samples from NHPs were collected and YFV infection confirmed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and genome sequencing at an interval of only 10 days. Near-complete genomes were generated using the Nanopore MinION sequencer. Phylogenetic analysis indicated that viral genomes were related to the South American genotype I, clustering with a genome detected in the Amazon region (state of Pará) in 2017, named YFVPA/MG sub-lineage. Fast YFV confirmation potentialised vaccination campaigns. MAIN CONCLUSIONS A new YFV introduction was detected in MG 6 years after the beginning of the major outbreak reported in the state (2015-2018). The YFV strain was not related to the sub-lineages previously reported in MG. No human cases have been reported, suggesting the importance of coordinated surveillance of NHPs using available technologies and supporting laboratories to ensure a quick response and implementation of contingency measures to avoid YFV spillover to humans.

摘要

INTRODUÇÃO: A vigilância entomológica tem se mostrado uma importante estratégia de monitoramento da fauna de culicídeos com vistas a predizer o risco de exposição a espécies vetoras de patógenos. Esse trabalho apresenta uma lista de mosquitos identificados pela primeira vez no Rio Grande do Sul e discute o potencial epidemiológico de algumas espécies ocorrentes no Município de Maquiné com registros em outras regiões do Estado. MÉTODOS: Os mosquitos foram coletados com aspirador de Nasci e armadilhas CDC, entre dezembro de 2006 e dezembro de 2008, em área silvestre, rural e urbana do Município de Maquiné. RESULTADOS: Foram verificadas 55 espécies, das quais 22 são registradas pela primeira vez no estado e 10 são potencialmente vetoras do vírus Saint Louis, Oropouche, Aura, Trocara, Ilhéus, Rocio, Una, West Nile e encefalite equina do leste. CONCLUSÕES: Esses dados demonstram a importância da Vigilância Entomológica como ferramenta de informação e ação para a Vigilância em Saúde.


INTRODUCTION: Entomological surveillance has proven to be an important strategy for monitoring culicidae fauna, aimed at predicting the risk of exposure to pathogen vector species. The present work reports species identified for the first time in the State Rio Grande do Sul and discusses the epidemiological potential displayed by mosquito species occurring in Maquiné municipality and in other regions of the State. METHODS: Mosquitoes were collected with Nasci vacuum and CDC light traps between December 2006 and December 2008, in the wild, rural and urban areas of Maquiné. RESULTS: Fifty-five species were verified, of which 22 were registered for the first time in the state and 10 are potential vector species for the Saint Louis, Oropouche, Aura, Trocara, Ilhéus, Rocio, Una, West Nile, and eastern equine encephalitis viruses. CONCLUSIONS: These data demonstrate the importance of entomological surveillance as a tool for gathering information and promoting Health Surveillance actions.
