“…The health consequences of measles and rubella infections can be lifelong and include economic losses for individuals, families and societies. [ 31 ] This study analyzed publicly available annual summary data of reported imported and domestic measles and rubella cases from 2011 to 2020 published by the TCDC and is the first report covering such an area in Taiwan in the past 10 years. During the period of investigation, more than 90% of the cases of measles and rubella were imported from Asian countries.…”

The risk of geographic transmission of infectious diseases due to air travel varies greatly. Our aim is to survey empirical data that provide a retrospective historical perspective on measles and rubella. This study used the open data website provided by the Taiwan Centers for Disease Control (TCDC) to extract the reported numbers of measles and rubella case between 2011 and 2020. There were 306 cases of measles and 135 cases of rubella. The incidence of measles and rubella per million population were 0 to 6.0 and 0 to 2.6, respectively. There was a gradual increase in the numbers of cases in those aged 20-39 years, and distinct duration patterns. It indicated that the risk of contracting rubella has significantly decreased in the last 5 years. Measles cases aged 20 to 39 years accounted for 72.5% of all cases. Rubella cases aged 20 to 39 years accounted for 59.3% of all cases. The male and residency in the Taipei metropolitan area or northern area were identified as potential risk factors for measles and rubella. Coverage with the first dose of the measles, mumps and rubella (MMR) vaccine in Taiwan increased from 97.31% to 98.86%, and the uptake rate of the second dose of the MMR vaccine increased from 95.73% to 98.39% between 2010 and 2020. Furthermore, the numbers of imported cases of measles (n = 0) and rubella (n = 0) reported during the coronavirus disease 2019 (COVID-19) pandemic were lower than those from 2011 to 2019. Measles and rubella cases were imported most frequently from Cambodia and Vietnam. This study represents the first report of confirmed cases of acquired measles and rubella from surveillance data of the TCDC between 2011 and 2020, also demonstrates that the numbers of cases of measles and rubella significantly decreased in Taiwan during the COVID-19 pandemic.Abbreviations: COVID-19 = coronavirus disease-2019, MMR = measles, mumps and rubella, TCDC = Taiwan centers for disease control, TNIDSS = Taiwan national infectious disease statistics system.

“…Contact tracing has been adopted as a public health practice since the 19th century. It has been used for the containment of syphilis, tuberculosis, measles, smallpox, HIV/AIDS and Ebola ( Gyselen, 1994 ; Samoff et al, 2007 ; Lin et al, 2012 ; Greiner et al, 2015 ; Mbvinjo et al, 2021 ). It was adopted on a large scale around the world during the recent outbreak of COVID-19.…”

This article focuses on transformative interactional practice in COVID-19 contact tracing telephone calls in Flanders (Belgium). It is based on a large corpus of recorded telephone conversations conducted by COVID-19 contact tracers with index patients in the period mid-2020 to mid-2022. The calls were conducted through government-contracted commercial call centers. For nearly 2 years and applied country-wide, this was the most prominent strategy in Belgium for breaking transmission chains. COVID-19 telephone contact tracing with infected patients counts as transformative professional work in two ways. First, in addition to the registration of recent contacts in a relevant time window, the work is oriented to awareness-raising about how patients and their co-dwellers can and should adjust their behavior by attending actively to critical aspects of the pandemic during an individual period of (potential) infection. This is the terrain of advice, interdictions and recommendations about quarantine, isolation, personal hygiene, etc. In addition, the focus on interactional attention indexes patients’ affect and emotions (e.g., anxiety, worry, or anger) in a period of health uncertainty and social isolation. The transformative work thus depends on successfully established rapport and empathetic, responsive behavior. Our analysis of the recorded conversational sequences focuses on the complexities of client-sensitive and responsive transformative sequences and highlights the constraints and affordances which surround the interactional task of ‘instructional awareness raising’ which is central to telephone contact tracing. Specifically, we detail the following dimensions of transformative sequences: (i) how do contact tracers deal with the knowledge status of clients, (ii) their use of upgrading/downgrading formulations, (iii) the use of humor and other mitigating strategies, and (iv) how contact tracers attend to interactional displays of affect and emotion. In a final section, we tie together our observations about the communication of particularized advice in a context of general measures through the twin notions of categorization/particularization-work. The findings in this paper are limited to the first step in the chain of contact tracing, i.e., telephone calls with tested and infected citizens.

RESUMEN Objetivo. Describir las buenas prácticas en vigilancia epidemiológica implementadas en El Salvador entre el 2019 y el 2023 para sostener la eliminación de sarampión, rubéola y síndrome de rubéola congénita. Método. Informe especial descriptivo de la implementación de las buenas prácticas de vigilancia epidemiológica y de laboratorio para sarampión, rubéola y síndrome de rubéola congénita, durante los años 2019 a 2023. Resultados. Durante el período 2019 a 2023, El Salvador no registró casos confirmados de sarampión, rubéola y síndrome de rubéola congénita. La tasa nacional de notificación de sarampión y rubéola para el año 2023 fue de 8,4 por 100 000 habitantes, para el 2022 fue de 9, para 2021 fue de 5,6, para el 2020 de 2,9 y para el 2019, de 8,2 por cada 100 000 habitantes. Desde la notificación del primer caso confirmado de COVID-19 en el país hasta la declaración del fin de la emergencia sanitaria internacional el 5 de mayo del 2023 por la Organización Mundial de la Salud, la tasa de notificación de casos sospechosos de sarampión y rubéola se mantuvo por arriba del estándar establecido para la vigilancia de sarampión, rubéola y rubéola congénita. Conclusiones. La implementación de estrategias de vigilancia epidemiológica de forma permanente y obligatoria permitió la sostenibilidad de la eliminación del sarampión y rubéola en El Salvador durante la pandemia de COVID-19.
