The aim of this study was to evaluate the impact of index case vaccination on SARS-CoV-2 transmission to household contacts. In our epidemiological cohort study (May 2022–November 2023), we surveyed registered index case vaccination status and test results for contacts (testing on day 0, and on day 7 for negative contacts) and calculated the secondary attack rate (SAR), i.e., newly infected contacts/susceptible included contacts. The association of the independent variable, index case COVID-19 vaccination (yes/no), with household contact infection was determined using the adjusted odds ratio (aOR) and its 95% confidence interval (CI). We recorded 181 index cases and 314 contacts, of whom 250 agreed to participate; 16 contacts were excluded upon testing positive on day 0. Of the 234 included contacts, 49.1% were women, and the mean (SD) age was 51.9 (19.8) years. The overall SAR of 37.2% (87/234) was lower in the contacts of both vaccinated index cases (34.9% vs. 63.2%; p = 0.014) and index cases with a previous SARS-CoV-2 infection history (27.0% vs. 46.3%; p = 0.002). Index case vaccination showed a protective effect against infection for their household contacts (aOR = 0.21; 95% CI: 0.07, 0.67). The household SAR was high when the Omicron variant circulated. Vaccinated index cases were less likely to transmit SARS-CoV-2 to their contacts.

Assessment of the level of knowledge and attitudes regarding COVID-19 and preventive measures in household contacts of COVID-19 cases after the acute phase of the pandemic. Survey among household contacts of COVID-19 cases conducted in healthcare centers in Navarre (1) and Catalonia (8) between May 2022 and July 2023. The frequency of use of preventive measures and the knowledge and attitudes towards COVID-19 were assessed through 12 items. 215 contacts participated who correctly used the preventive measures (>85%), except for facemasks (35.8%) and interpersonal distance (47%); >85% showed adequate knowledge (5/6 items) and >80% had a positive attitude (3/6 items). Moreover, 54.7% considered that COVID-19 negatively affected their life and 54.1% that it is better to develop immunity by getting infected than by vaccination. Household contacts show a correct level of knowledge and positive attitude towards the disease and its preventive measures.

Background: Burnout syndrome is an occupational phenomenon that affects the health and well-being of workers. However, its frequency in populations referred to specialized occupational health units in specific territorial contexts is poorly documented. Objective: To estimate the frequency of suspected burnout syndrome and to explore its association with sociodemographic, occupational, and lifestyle variables in workers referred from Primary Care to the occupational health unit of Lleida, Alt Pirineu, and Aran during 2024. Methodology: A cross-sectional observational study was conducted among 51 workers referred from Primary Care to the occupational health unit in Lleida, Alt Pirineu, and Aran in 2024. Sociodemographic data were collected, and the Maslach Burnout Inventory – General Survey (MBI-GS) was administered. The main outcome was MBI-GS positivity. Odds Ratios (OR) with 95% confidence intervals were calculated to explore the association between positivity and the independent variables. Main results: Nineteen of the 51 workers (37.3%) presented positive results, indicating suspected burnout in this referred population. Most of the associations analyzed were not statistically significant. Workers aged 26 to 45 years showed a lower risk of positivity. Conclusion: In this specific sample of workers referred to the occupational health unit, suspected burnout was a frequent occurrence. The findings should be interpreted with caution due to the small sample size and the selected nature of the population; therefore, the results are considered exploratory.

This study aims to describe the long-term changes in the knowledge of, and attitudes towards, COVID-19 and its preventive measures in northern Spain. A telephonic survey was performed among household contacts of COVID-19 cases in Catalonia and Navarre between May 2022 and December 2023. Knowledge and attitudes were assessed through 12 questions using a Likert scale, and responses were grouped as correct or incorrect. The change from baseline to the 6-month follow-up was evaluated with the absolute difference (AD) using the proportion of correct answers. At baseline, 299 subjects were contacted, of whom 63.2% (189) completed the 6-month follow-up. Correct knowledge of transmission (>85%) and the use of preventive measures (>92%) were observed at baseline and maintained over time. The attitudes towards face mask use remained adequate over the course of six months (>79%). However, attitudes regarding the use of face masks indoors (AD = −16.4%; p < 0.001) and those who thought that COVID-19 had a negative impact on their lives (AD = −16.5%; p < 0.001) decreased after 6 months. In the post-acute phase of the pandemic, household contacts maintained the correct level of knowledge towards COVID-19, while some attitudes decreased. These results should serve as a guide for health policy makers in decision-making in case of a new increase in the incidence of SARS-CoV-2.

Introducción: el síndrome de burnout en trabajadores ha sido ampliamente estudiado, especialmente en profesionales sanitarios durante la pandemia. Objetivo: proporcionar una descripción general de la evidencia existente sobre el síndrome de burnout en colectivos de trabajadores no dedicados a la salud humana entre 2020-2024. Métodos: revisión de alcance realizada de acuerdo con la Extensión de Revisión de Alcance de las Directrices PRISMA. Búsqueda bibliográfica en las bases de datos PubMed y Web of Science el 2 de enero de 2025. Se utilizó la herramienta de Joanna Briggs Institute para estudios de cohortes en la valoración de la calidad metodológica. Resultados principales: 12 de los 494 estudios obtenidos cumplían los criterios de inclusión, sumando 12612 participantes de diferentes profesiones, los estudios de origen asiático aportaron la mayoría de participantes, 77.1% (N=9723). El 42% de los estudios se realizaron en Europa. El 50% utilizó el Maslach Burnout Inventory o alguna de sus variantes en la determinación del burnout i un 58.3% de los estudios correlacionaron el burnout con otros problemas psicosociales y otras variables. Conclusión general: los factores intervinientes en el burnout van más allá de la COVID-19, también en colectivos de trabajadores no sanitarios, sugiriendo causas estructurales e intrínsecas organizacionales. La futura investigación debe enfocarse en estudios longitudinales que identifiquen las relaciones causales y que permitan diseñar y evaluar intervenciones en las empresas, para prevenir y evitar problemas de salud psicosocial en los trabajadores, implicando a otros colectivos y regiones para obtener una perspectiva global completa.
