O viajante como agente ativo na transmissibilidade do SARS-CoV-2: uma revisão sistemática / The traveler as an active agent of SARS-CoV-2 transmission: a systematic review

O objetivo deste trabalho foi evidenciar o papel dos viajantes na transmissão e na disseminação do novo coronavírus. A busca pelos artigos foi realizada nas bases de dados PubMed®, SciELO, MEDLINE®, Cochrane, Center for Disease Control and Prevention e UpToDate. Foram incluídos artigos relacionados à transmissibilidade, principalmente aqueles associados à disseminação realizada por viajantes, do novo coronavírus. Excluíram-se artigos relacionados a outros surtos de coronavírus. Todos os estudos foram lidos e analisados integralmente. Onze artigos foram selecionados e tabulados, dos quais se pôde desenvolver uma fundamentação teórica, que expõe o grande impacto dos viajantes perante o crescimento da pandemia relacionada ao SARS-CoV-2, levando em consideração as diversas formas com que esse vírus pode se propagar, sendo elas por contato com superfícies contaminadas ou pessoa a pessoa, visto que a infecção pode ser decorrente de gotículas, aerossóis, fômites e, possivelmente, contato sexual, estando os indivíduos sintomáticos ou não.

The objective of this study was to highlight the travelers role in the transmission and dissemination of new coronavirus. The search for the articles was carried out in PubMed®, SciELO, MEDLINE®, Cochrane, Centers for Disease Control and Prevention, and UpToDate databases. Articles related with transmissibility of the new coronavirus were included, mainly those linked with the dissemination from travelers. Articles related with other coronavirus outbreaks were excluded. All of the studies were read and analyzed in their entirety. Eleven articles were selected and tabulated, from which a theoretical framework was developed, which exposes the great impact of travelers in the face of the growth of the pandemic related to the SARS-CoV-2, considering the several ways in which this virus can spread, either through contact with contaminated surfaces or person-to-person, since the infection may occur through droplets, aerosols, fomites, and possibly sexual contact, whether individuals are symptomatic or not.

Una consideración sobre el artículo: Brotes, epidemias, eventos y otros términos epidemiológicos de uso cotidiano / Considerations on the article: Outbreaks, epidemics, events and other epidemiological terms of frequent use

Hemos leído con sumo interés el trabajo de Peláez y Más1 publicado recientemente en su revista. A raíz de los datos expuestos en su contenido, quisiéramos, primeramente, puntualizar la importancia de tener en cuenta el marco legal de la Organización Mundial de la Salud (OMS), como lo es el Reglamento Sanitario Internacional (RSI).2 El RSI es un instrumento jurídico internacional de carácter vinculante para 194 países, entre ellos todos los Estados Miembros de la OMS. Tiene el objetivo de ayudar a la comunidad a prevenir y afrontar riesgos agudos de salud pública, susceptibles de atravesar fronteras y amenazar a poblaciones de todo el mundo. Actualmente el RSI vigente tiene el objetivo de ayudar...(AU)

Diagnostic algorithm for the confirmation of cases of measles and rubella in Mexico

Due to the successful implementation of measles and rubella elimination strategies, Mexico announced the interruption of endemic transmission of measles in 1996 and that of rubella in 2008. After a verification process, the region of the Americas was declared free of rubella and congenital rubella syndrome in 2015 and of measles in 2016. In order to maintain the elimination status in Mexico, it is essential to continue laboratory surveillance within the framework of the Global Measles and Rubella Laboratory Network. The Institute of Epidemiological Diagnosis and Reference, through the National Network of Public Health Laboratories, guarantees timely and reliable results in view of the possible reintroduction of these and other emerging pathogens.
