“… 19 Information about the community prevalence of anti-SARS-CoV-2 antibodies may be used as a gauge of community immunity before the introduction of vaccines. 20 Such a study was done in KSA among blood donors and the seroprevalence was 1.4% 21 which is similar to those reported among HCWs in most of the KSA studies. Another study that included over 6000 HCWs in Spain conducted in 17 hospitals across four regions in the country had a seroprevalence of 4.32% amongst the participants.…”

Background The nature of the healthcare workers’ jobs standing at the frontline against the coronavirus disease 2019 (COVID-19) puts them at a higher risk of unknowingly contracting the disease and potentially contributing to the spread. This study aims to assess the overall positive seroconversion prevalence of SARS-CoV-2. Methods This is a longitudinal cohort study of healthcare workers at Johns Hopkins Aramco Healthcare (JHAH). JHAH is a tertiary hospital located in Dhahran serving patients in several districts in the Eastern Province of Saudi Arabia. Participants were recruited between June and December 2020. Each participant had a serology blood test and completed the World Health Organization’s risk factor assessment questionnaire. Results This study included 682 participants working in JHAH, representing 15.7% of our population. Out of the 682 participants, 15.2% had a positive SARS-CoV-2 rt-PCR before taking part in the study. However, only 87 tested positive for SARS-CoV-2 antibodies, a prevalence of 12.7% of all participants. Out of the 87 positives for SARS-CoV-2 antibodies, 17 participants never tested positive for COVID-19 rt-PCR, a prevalence of 2.9%. Moreover, not properly using alcohol-based hand rub or soap and water after the risk of body fluid exposure and wearing personal protective equipment when indicated were found to be statistically significant to having a positive SARS-CoV-2 IgG assay. Conclusion Positive seroconversion rate was considerably low during the first wave of COVID-19 amongst JHAH’s healthcare workers and similar to other healthcare organizations in Saudi Arabia. Seropositivity correlated significantly with following infection prevention and control recommendations. Clinicaltrials.gov Identifier NCT04469647.

“…HCWs play a central role in handling the ongoing coronavirus disease 2019 (COVID-19) pandemic [ 3 , 4 ]. Monitoring HCWs, both symptomatic and asymptomatic, through screening programs is crucial to rapidly identify and isolate infected subjects and, consequently, to avoid hospital infection outbreaks and to allow healthcare workers to return to work promptly [ 5 , 6 , 7 , 8 ]. Moreover, alongside screening programs, the implementation of preventive measures and protocols in hospital settings has been shown to be highly effective in reducing the number of cases [ 9 ].…”

Background: SARS-CoV-2 has infected many healthcare workers and (HCWs) worldwide. The aim of this study was to determine, analyze, and compare the frequency and characteristics of COVID-19 cases among HCWs of the University Hospital of Bari. Methods: A retrospective observational study was conducted after preventive protocol implementation. The SARS-CoV-2 infection frequency was determined by real-time reverse transcription-polymerase chain reaction on nasopharyngeal samples. Results: Overall, 519 HCWs (9%) tested positive among a total of 6030 HCWs during the three waves. The highest frequency of COVID-19 cases (n = 326; 63%) was observed during the 2nd wave, from September 2020 to December 2020, and the lowest (n = 34; 7%) was observed during the 1st wave, from March 2020 to August 2020 (p < 0.001). Working in a designated COVID-19 department was not a risk factor for infection. Conclusions: The correct use of personal protective equipment and the early identification of symptomatic workers are still essential factors to avoid nosocomial clusters, even in this current phase of vaccine availability.

“…6 En el hospital, los médicos en formación son uno de los grupos más expuestos a SARS-CoV-2 presentando el tercer lugar de los casos, lo que difiere de lo reportado por Guarnieri y cols. 7 en donde refieren como hallazgo curioso que la población de médicos residentes fue la menos afectada, quizá porque no tuvieron contacto con familiares y amigos, y que estaban distribuidos por turnos lo que permitió una menor exposición a pacientes. 7 Un estudio en México refiere que la incidencia de COVID-19 en personal de salud es de 10.1%; sin embargo, en la institución fue mayor presentándose una incidencia de 35% tomando en cuenta la población de personal de salud en el periodo de estudio (3700 trabajadores).…”

Un brote en pandemia en personal de salud

et al. 2023

View full text Add to dashboard Cite

ANTECEDENTES: Un brote se define como el aumento de casos mayor a lo esperado con asociación epidemiológica entre sí. Durante la pandemia de COVID-19 10.1% de casos totales se presentaron en personal de salud en México, sin embargo, la circulación de la nueva variante Ómicron, con mayor transmisibilidad, representa un riesgo mayor para la presencia de brotes. OBJETIVO: Describir la presencia de un brote por infección por SARS-CoV-2 en personal de salud de un hospital pediátrico durante la pandemia.MÉTODOS: Se realizó un estudio de brote en personal de salud con diagnóstico de infección por SARS-CoV-2, en un hospital de tercer nivel pediátrico, del 1 de enero del 2021 al 30 de enero de 2022. Se analizó el aumento de casos confirmados por laboratorio en enero, mayor a lo reportado en el periodo anterior, considerando un brote y se reforzaron las medidas de prevención general en la población. RESULTADOS: Se corroboró un brote con 514 casos en personal de salud en enero de 2022 identificando 27.5% como intrahospitalarios. La circulación de una nueva variante con alta transmisibilidad, aunado a la relajación de medidas de prevención expresada por los trabajadores secundario al estado de vacunación y la percepción de menor riesgo ante la infección por SARS-CoV-2, probablemente llevaron a la ocurrencia del brote.CONCLUSIONES: La presencia de un brote determina la importancia de reforzar las medidas de prevención de manera continua y concientizar al personal de adoptarlas como una conducta cotidiana para evitar brotes.
