Methods: Patients followed with a diagnosis of SARI between 15 December, 2015 and 22 May, 2016 were included in the study. The patients were evaluated for demographic and clinical characteristics. Respiratory tract multiplex polymerase chain reaction (PCR) test was performed for all patients’ nasopharyngeal smear samples. Results: A total of 107 patients were included in the study. Of the patients, 69 (64.5%) were male, and median age was 68 (range, 0-95) years. Mean duration of complaints before admission was 3.8 days. Mean hospitalization time was 11.7 days, and 23.4% of patients were followed in intensive care unit. Most frequent admissions were between second and seventh weeks of 2016. Viral agents were found in 41(38.3%) patients in respiratory tract multiplex polymerase chain reaction (PCR) test. Of the agents, 80.5% were influenza A virus (63.4% H1N1, 7.3% H3N2, 9.7% influenza A), 14.6% were influenza B virus, 2.4% were coronavirus OC43, and 2.4% were human metapneumovirus. Crude mortality was 15.9%, SARI-specific mortality was 8.4%, influenza A (H1N1)-related mortality was 11.5%. There were no significant differences for underlying diseases and laboratory findings other than presence of chronic obstructive pulmonary disease, and elevated alanine and aspartate aminotransferase levels. Admission to intensive care unit and mortality were similar for both groups. When patients were evaluated according to the duration of complaints prior to admission, PCR positivity, necessity for intensive care unit admission and mortality were not found to be significantly different between patients with ≤4 days and >4 days of complaints. Patients with mortality had an increased rate of admission to intensive care unit when compared with patients discharged with full recovery. Conclusions: Our regional findings for 2015-2016 influenza season were found to be similar with national and European data.
