RESUMO
The aim of this study is to describe an outbreak of dermatophilosis at an equestrian center in Castilla la Mancha (central Spain), which affected 16.6% (5/30) of the animals. Research was carried out to establish the mode of transmission and spread to other horses in the herd. Clinical features, diagnostic methods and treatment are also described.
O objetivo deste estudo é descrever um surto de dermatofilose em um centro equestre em Castilla la Mancha (centro da Espanha), no qual 16,6% (5/30) dos animais foram afetados. Foi realizada uma pesquisa para estabelecer o modo de transmissão e a disseminação para outros cavalos do rebanho. As características clínicas, os métodos de diagnóstico e o tratamento também são descritos.
RESUMO
Resumen: Objetivo: Identificar evidencia científica sobre la transmisión indirecta del SARS-CoV-2 en espacios extrahospitalarios y medidas poblacionales para su prevención. Material y métodos: Una revisión rápida de lo publicado en PubMed y MedRxiv entre 01/12/2019 y 24/04/2020 sobre los temas 1) la contaminación y viabilidad del SARS-CoV-2 en distintas superficies inanimadas; 2) la efectividad desinfectante ante SARS-CoV-2 de productos accesibles a nivel domiciliario; 3) los casos y brotes de contagio de SARS-CoV-2 por medio de superficies. Resultados: Una alta proporción de los objetos de personas infectadas con SARS-CoV-2 (inodoro, ollas y tabletas electrónicas) se encuentran contaminados. Este virus permanece viable desde horas hasta días en papel, cartón, tela, vidrio, madera, plástico, acero y cubrebocas. El etanol, 2-propanol, cloro y jabón son efectivos para desactivarlo. Existe poca evidencia sobre casos y brotes por contagio indirecto. Conclusiones: Se requieren estudios que determinen la dosis mínima infectante por autoinoculación. Apelando al principio precautorio, se incluyeron recomendaciones para reducir el riesgo de contagio indirecto.
Abstract: Objective: To identify scientific evidence on the indirect transmission of SARS-CoV-2 in out-of-hospital spaces and population measures for its prevention. Materials and methods: A rapid review of what has been published in PubMed and MedRxiv between 12/01/2019 and 04/24/2020, on the topics: 1) the contamination and viability of SARS-CoV-2 in different inanimate surfaces; 2) products accessible at home level with disinfectant efficacy against SARS-CoV-2; 3) the cases and outbreaks of SARS-CoV-2 transmitted through surfaces. Results: A high proportion of the objects people infected with SARS-CoV-2 use (toilet, pots and electronic tablets) are contaminated. This virus remains viable from hours to days in paper, cardboard, cloth, glass, wood, plastic, steel and face masks. Ethanol, 2-propanol, chlorine, and soap are effective in deactivating it. There is little evidence on cases and outbreaks by indirect contact. Conclusions: Studies are required to determine the minimum infectious dose by autoinoculation. Appealing to the precautionary principle, we include recommendations to reduce the risk of indirect contagion.
