Gripe y otras infecciones respiratorias agudas en la población trabajadora. Impacto del brote de gripe A (H1N1) / Flu and other Acute Respiratory Infections in the Working Population. The Impact of Influenza A (H1N1) Epidemic

IntroducciónEl objetivo de este estudio fue evaluar el impacto que tuvieron la gripe y el resto de infecciones respiratorias agudas (IRA) en la población trabajadora catalana entre enero de 2007 y diciembre de 2009, periodo de tiempo que incluyó el brote de gripe por virus A (H1N1) en nuestro medio.MétodosSe analizaron todos los procesos de incapacidad temporal (IT) diagnosticados como gripe o como otras IRA en la población trabajadora de Cataluña, España, entre enero de 2007 y diciembre de 2009. Se calcularon la incidencia semanal y mensual y un umbral epidémico de IT por gripe a partir del cual poder definir el brote epidémico en la población trabajadora.ResultadosLa incidencia acumulada anual de IT por gripe por 100.000 trabajadores fue de 1.260,6 en 2007, 915,2 en 2008 y 2.377,2 en 2009. Las curvas de incidencia indican brotes epidémicos en los meses de enero o febrero de cada año, además de un segundo brote en el mes de noviembre de 2009, coincidiendo con la pandemia de virus A (H1N1) en nuestro país. En 2009 la incidencia de gripe y de otras IRA fue más alta en los trabajadores de los sectores salud-servicios sociales que en el resto de los trabajadores (p<0,001).ConclusiónEste estudio contribuye a conocer las consecuencias de la gripe y las otras IRA sobre la población trabajadora, durante un periodo de tiempo que incluyó el brote por virus A (H1N1)(AU)

IntroductionThis study aims to asses the impact of influenza and other acute respiratory infectious diseases (ARI) on the Catalan working population between January 2007 and December 2009, including the period of the influenza virus A (H1N1) pandemic in our region.MethodsAll certified sickness absence episodes (sick-leave) due to influenza and other ARI amongst the working population of Catalonia, Spain, were analyzed from January 2007 to December 2009. Monthly and weekly incidence was calculated, as well as an influenza sick-leave threshold, in order to identify the epidemic season in the working population.ResultsRegistered annual sick-leave incidence for influenza-like illnesses (ILI) per 100,000 workers was 1,260.6 in 2007, 915.2 in 2008 and 2,377.2 in 2009. Epidemic curves show monthly peaks in January-February each year, plus a second peak in November 2009 corresponding to the influenza virus A (H1N1) pandemic in our region. In 2009 sick-leave incidence for ILI and other ARI was higher in workers from the Health-Social Services sector than in the other workers (p<0.001).ConclusionThis study contributes to the knowledge on the impact of influenza and other ARI on the general workforce, during a period of time including the outbreak of influenza virus A (H1N1)(AU)

INTRODUCTION: This study aims to asses the impact of influenza and other acute respiratory infectious diseases (ARI) on the Catalan working population between January 2007 and December 2009, including the period of the influenza virus A (H1N1) pandemic in our region. METHODS: All certified sickness absence episodes (sick-leave) due to influenza and other ARI amongst the working population of Catalonia, Spain, were analyzed from January 2007 to December 2009. Monthly and weekly incidence was calculated, as well as an influenza sick-leave threshold, in order to identify the epidemic season in the working population. RESULTS: Registered annual sick-leave incidence for influenza-like illnesses (ILI) per 100,000 workers was 1,260.6 in 2007, 915.2 in 2008 and 2,377.2 in 2009. Epidemic curves show monthly peaks in January-February each year, plus a second peak in November 2009 corresponding to the influenza virus A (H1N1) pandemic in our region. In 2009 sick-leave incidence for ILI and other ARI was higher in workers from the Health-Social Services sector than in the other workers (p<0.001). CONCLUSION: This study contributes to the knowledge on the impact of influenza and other ARI on the general workforce, during a period of time including the outbreak of influenza virus A (H1N1).
