Abstract:

Respiratory infections caused by Parainfluenza viruses (PIV) are among the main causes of morbidity and hospitalization in babies and young children. This retrospective study aims to investigate the frequency and seasonal distribution of Parainfluenza virus infections in children who are traced due to infection of the lower respiratory tract. Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: Patients and Method: The findings: The study found that 224 of the children in 1983 were diagnosed (11%). 3) any of the types of PIV has been detected in the respiratory path sample. In terms of the distribution of the subtypes, the factor is most frequently identified as PIV-3 (75%). This is followed by 15.17% with PIV-4, 5.8% with PIV-1 and 4% with PIV-2. 75.9% of patients were under 5 years of age. When seasonal distribution was studied, it was found that PIV-3 was frequently (53.6%) in the summer months, while PIV-1 and PIV-2 were closely observed in the autumn and winter months. The patient group has often identified PIV-3, which is a sub- respiratory infection factor. The determination of the factors of respiratory infection caused by PIV by the m-PZR method will be beneficial for clinics in the treatment and protection of these viral infections.
