目的对龙岗区呼吸道病毒感染病例样品进行检测,并对其流行特征进行分析。方法在区内哨点医院采集呼吸道感染病例咽拭子889份,用实时荧光定量PCR法对流感病毒(A型、B型)、腺病毒(ADV)、人鼻病毒(HRV)、副流感病毒(PIV-1、PIV-2和PIV-3亚型)、呼吸道合胞病毒(RSV-A和RSV-B亚型)、冠状病毒(CoV-229E、CoV-OC43、CoVNL63和CoV-HKU1亚型)和人偏肺病毒(hMPV-A和hMPV-B亚型)共7种呼吸道病毒15个亚型进行检测。结果流感病毒是龙岗区最常见的呼吸道感染病原,其次是人鼻病毒;1~7月呼吸道病毒阳性率保持较高水平;≤5岁儿童对各种病毒易感;鼻病毒和腺病毒是混合感染中最常见的病原。结论应继续加强常见呼吸道病毒的监测,对呼吸道传染病的预防和控制具有重要意义。
Objective To detect the cases of respiratory virus infection in Longgang District and analyze its epidemiological characteristics. Methods 889 throat swabs of respiratory tract infection were collected from sentinel hospitals in the district. The positive rate of influenza virus (A, B), adenovirus (ADV), human rhinovirus (HRV), parainfluenza virus (PIV-1, PIV-2 and PIV-3 subtypes), respiratory syncytial virus (RSV-A and RSV-B subtypes), coronaviruses (CoV-229E, CoV-OC43, CoVNL63 and CoV-HKU1 subtypes ) And human metapneumovirus (hMPV-A and hMPV-B subtypes) were detected in 15 subtypes of 7 respiratory viruses. Results The influenza virus was the most common respiratory infection in Longgang District, followed by human rhinovirus. The positive rate of respiratory virus was maintained at a high level from January to July. Children ≤5 years old were susceptible to various viruses. Rhinovirus and adenovirus were mixed The most common pathogen of infection. Conclusion The monitoring of common respiratory viruses should be continuously strengthened, which is of great significance for the prevention and control of respiratory infectious diseases.
