Comportamiento epidemiológico de SARS-CoV-2 en población trabajadora afiliada al Instituto Mexicano del Seguro Social

Abstract: Objetivo. Describir el comportamiento de la epidemia de SARS-CoV-2 entre los trabajadores afiliados al Instituto Mexicano del Seguro Social (IMSS). Material y métodos. Se analizaron las incapacidades temporales para el trabajo por enfermedades respiratorias (ITT-ER), las hospitalizaciones y defunciones asociadas durante el periodo del 1 marzo al 31 diciembre 2020. Se estimó la tasa de ataque (TA) por SARS-CoV-2, así como los riesgos relativos (RR) de ITT-ER, hos­pitalización y defunción. Resultados. De los tra… Show more

“…15 In contrast, hospitalization rates during the Omicron wave were well below those reported during previous waves (3.8 vs. 28.4 per 1 000 SARS-CoV-2-positive workers). 16 Our results agree with observations suggesting that Omicron breakthrough infections were frequent among vaccinated populations but generally associated with less severe disease. 13,[23][24][25][26][27] During the Omicron-predominant period, we documented that full vaccination with any of the seven vaccines evaluated was associated with a 2.7-fold reduction in the risk of Covid-19-related hospitalization and a 4.2-fold reduction in risk of death (table I).…”

“…To identify evaluation participants (figure 1), using workers' Individual Population Registry Identifiers (Clave Única de Registro de Población, CURP, in Spanish), we first selected all respiratory-disease STDCs (RD-STDCs) authorized from January 2 to March 5, 2022 (n= 1 410 675) from the IMSS STDC database under specific ICD-10: Covid-19 [U070, U071, U072, U07E, U07S, B342, B972], acute respiratory diseases [J01, J04-J06, J20, J21], influenza [J10, J11], pneumonia [J12-J18], and other [J029, J00X, J02X, J039, J22X]. 15,16 We then linked the CURP to the IMSS Epidemiological Surveillance Online Notification System (Sistema de Notificación en Línea para la Vigilancia Epidemiológica, Sinolave, in Spanish) database to identify workers with a SARS-CoV-2 test and their information (i.e., sex, age, salary group, state of residency), date of RD-STDC authorization, previous RD-STDCs during 2020-2021, and ICD10 diagnosis (n= 928 590). Thirty-one percent of workers with a RD-STDC were tested for SARS-CoV-2 (1.7% RT-PCR and 98.3% antigen tests) at IMSS facilities; 92.3% tested positive for SARS-CoV-2.…”
