Patients were eligible to be included in the study when they were hospitalised for at least 24 hours, but not longer than 48 hours, had a swab taken ≤7 days after self-reported disease onset, did not test positive and were not hospitalised for any influenza virus in the current season before the inclusion, and were suffering from SARI with at least one of the systemic symptoms (fever, malaise, headache and myalgia) or deterioration of general condition or deterioration of functional status, and at least one of the respiratory symptoms (cough, sore throat and shortness of breath). This study aimed to estimate SIVE against laboratory-confirmed influenza virus infection in patients admitted to the hospital due to SARI in Lithuania during the 2015-2016 season. ./cache/cord-318556-a28bowqy.txt ./txt/cord-318556-a28bowqy.txt
