[Pandemic influenza A/H1N1/2009 virus RNA isolation rate in specimens of patients diagnosed as flu in a University Hospital in Eastern Black Sea Region, Turkey].
Swine origin influenza virus (S-OIV) has been of global concern towards the end of 2009 with its high morbidity rate and pandemic aspect. In this study, the presence of pandemic influenza A/H1N1/2009 virus RNA was investigated in patients clinically diagnosed as influenza infection in the university hospital in Trabzon province (located at Eastern Black Sea Region, Turkey). Oropharyngeal and nasal swab samples were collected from 211 patients (mean age: 18.5 years) who were admitted to our hospital between 16 November 2009 and 10 January 2010. Pandemic influenza A/H1N1/2009 virus RNA in the samples was investigated by real-time polymerase chain reaction. Viral RNA was detected in 41 of the patients (19.4%). The mean age of the cases was 11.7 years old. The highest positivity rate (44%) was seen in samples collected between 23-29 December 2009, while no positive samples were detected after 29 December 2009.
