Abstract:Objective To investigate the epidemiological characteristics of influenza virus A (IVA), influenza virus B (IVB), respiratory syncytial virus (RSV), adenovirus (ADV), parainfluenza virus type 1(PIV 1), PIV 2 and PIV 3 in children of Wenling, so as to provide the data for the clinical diagnosis, treatment, epidemic surveillance, and preventive strategy. Methods From January 2014 to December 2016, Nasopharyngeal swab samples from 1826 children presenting influenza-like symptoms in Wenling were collected, and the samples were determined by direct fluorescent antibody staining (DFA) for the 7 common respiratory viruses. The positive rates, epidemiological characteristics of different month and age were analyzed. Results There were 496 cases of positive virus specimens in the specimens, with the total positive rate of 27.16%. Among the seven kinds of virus, the highest infection rate was RSV, and the lowest infection rate was PIV 2. There was no significant difference in terms of the constituent ratio for seven kinds of virus among 1826 cases of infected children (including girls and boys) (P > 0.05). The positive ratio of viruses were detected highly in January, February, March, which was found the highest in February (48.6%) and the lowest in October (21.4%). There was statistical significance for the positive rates of RSV, PIV3, ADV, and PIV1 among 0~1, 1~3, 3~6, and beyond 6 age groups (P < 0.05). Conclusion RSV and PIV 3 are the most common virus among children with influenza-like symptoms in Wenling. The epidemic of respiratory viruses could be obvious seasonal characteristics, and the highest rate of respiratory infection might be in February children under 3 years old are susceptible to these viruses.
