The 2013-2014 circulation of seasonal influenza in the northern hemisphere began officially in epidemiological week (EW) 40 of 2013, with an increase in the number of influenza-like illness (ILI) and hospitalizations reported starting in EW 50 of 2013. This is within expected levels for this time of year. Every year, an increase in influenza is reported primarily during the autumn and winter months in the northern hemisphere. Currently, the predominant virus is influenza A(H1N1)pdm09, which is considered a seasonal virus, signifying that it will continue to circulate like other influenza viruses. Clinical management and outbreak response is the same as for other seasonal influenza viruses. La temporada 2013-2014 de circulación de influenza en el hemisferio norte se inició oficialmente a partir de la semana epidemiológica (SE) 40 del 2013, registrándose un incremento a partir de la SE 50 tanto en el número de Enfermedad Tipo Influenza (ETI) como de hospitalizaciones por esta enfermedad. Esta situación está dentro de lo esperado para esta época del año. Cada año se registra un incremento en la actividad de influenza principalmente durante el otoño e invierno en el hemisferio norte. Actualmente, el virus predominante es el de influenza A(H1N1)pdm09, el cual es considerado un virus estacional, lo que significa que seguirá circulando como los demás virus de influenza. Su manejo clínico y respuesta a brotes es igual al de otros virus de influenza estacional.
