Investigation of the prevalence of influenza viruses in viral respiratory tract infections and it's role in other respiratory viruses

Respiratory infections can be easily spread through droplets thrown from infected people during coughing, sneezing and it can be resulted disease tables with high death rates (Cowling et al, 1935). The majority of these infections are caused by viruses like rhinovirus, influenza virus, parainfluenza virus, rsv, adenovirus and enteroviruses (Bozkaya, 2004). In this study, it was aimed to determine which virus was active in which age and gender groups, and to determine the location of influenza viruses among other respiratory viruses in patients with multiple real-time PCR and to determine which virus was present in the clinical and outpatient clinics of Istanbul University School of Medicine during the 2016-2017. As a result, viral infections were most frequently detected in the 0-5 age group, it has been occured especially in January and found more frequently in males as gender. The most common cause of virus infections are rhinovirus, followed by influenza virus. Although influenza A H3N2 is the predominant influenza strain. In this period, influenza A H3N2 was seen as predominant in the world and at the same time, it has been observed that the northern hemisphere countries and Algeria are also performing peaks in January as in Turkey. In this study, mix infections were also detected. The most common causes of these mix infections are rhinovirus, rsv and coronavirus. Influenza virus is also detected as a formed of mix infections. In these infections influenza viruses are being together with rsv, coronavirus, adenovirus, and parainfluenza viruses.
