RESUMEN
BACKGROUND: This study compared surveillance of cases of sickness absence due to illness caused by influenza and reported in Andalusia and Catalonia in the period 2007-2009. METHODS: A time series of incident cases of sickness absence due to influenza, by sex and age, in which episodes in Andalusia and Catalonia in a previous epidemic period (from 01/01/2007 through 30/09/2009) were compared to the pandemic period (last three months of 2009). The weekly number of new cases of sickness absence due to influenza was calculated, and the minimum, median and maximum values were plotted for each of these two periods. RESULTS: Unexpectedly, women had a higher proportion of new cases of sickness absence due to influenza during the pandemic period (52.2% in Catalonia and 49.7% in Andalusia). During both periods the 25 to 34 year old age group had a higher number of new cases of sickness absence both in Catalonia (37.439 in the epidemic period and 15.379 in the pandemic) and Andalusia (20.465 epidemic period and 9.630 pandemic period). The arrival of the pandemic was around November (approximately 10.000 cases in Catalonia and 5.000 cases in Andalusia), resulting in a significant increase of cases in contrast to the median of the epidemic period. CONCLUSIONS: During the 2009 pandemic, there was an increase in new cases of sickness absence due to influenza, somewhat greater in Catalonia than Andalusia, with an earlier peak in November, especially among women in these two autonomous communities.

Fundamentos: La gripe estacional es una causa frecuente de episodios de incapacidad temporal por contingencia común (ITcc). En este estudio se valora el impacto laboral de la gripe pandémica (H1N1) 2009 en Andalucía y Cataluña durante el periodo 2007- 2009. Métodos: Estudio de series temporales de los casos de ITcc por gripe, según edad y sexo. Se compararon los nuevos casos de ITcc por gripe en un primer periodo epidémico (de 01/01/2007 hasta 30/09/2009) y un segundo periodo pandémico (tres últimos meses de 2009). Se calculó el número semanal de nuevos casos de ITcc por gripe, representándose gráficamente los valores mínimo, mediano y máximo de los casos notificados durante el periodo epidémico y el pandémico. Resultados:Al contrario de lo esperado, las mujeres presentaron 52,2% en Cataluña y 49,7% en Andalucía de nuevos casos de ITcc por gripe durante el periodo pandémico. Durante ambos periodos, el grupo de edad de 25 a 34 años presentó mayor número de casos tanto en Cataluña (37.439 en el periodo epidémico y 15.379 en el pandémico) como en Andalucía (periodo epidémico 20.465 y periodo pandémico 9.630). La llegada de la pandemia se situó alrededor del mes de noviembre (aproximadamente 10.000 casos en Cataluña y 5.000 casos en Andalucía), produciéndose un importante aumento de casos respecto a la mediana del periodo epidémico. Conclusiones: La aparición de la pandemia de gripe produjo un incremento importante de casos de ITcc, algo superior en Cataluña que en Andalucía, adelantándose su acmé a noviembre, especialmente en las mujeres de las dos Comunidades Autónomas(AU)
