cord-002972-ge7qt256	Torner, Núria	Descriptive study of severe hospitalized cases of laboratory-confirmed influenza during five epidemic seasons (2010–2015)	2018-04-14		.txt	text/plain	2674	139	47	OBJECTIVE: The Plan of Information on Acute Respiratory Infections in Catalonia (PIDIRAC) included the surveillance of severe hospitalized cases of laboratory-confirmed influenza (SHCLCI) in 2009. Surveillance of SHCLCI provides an estimate of the severity of seasonal influenza epidemics and the identification and characterization of at-risk groups in order to facilitate preventive measures such as vaccination and early antiviral treatment. Given the situation generated by the 2009 pandemic caused by the new influenza A (H1N1) pdm09 virus, the PIDIRAC sentinel network included surveillance of severe hospitalized cases of laboratory-confirmed influenza (SHCLCI) to assess severity. The aims of SHCLCI surveillance are to provide an estimate of the severity of seasonal influenza epidemics to identify and characterize the risk groups that may present serious complications as a result of infection by circulating influenza viruses or their association with some underlying diseases and to identify the virological characteristics of viruses associated with these severe cases, such as genetic changes and/or antigenic changes that lead to increased virulence.	./cache/cord-002972-ge7qt256.txt	./txt/cord-002972-ge7qt256.txt
