Lower Respiratory Tract Infection due to coinfection of Influenza A Virus and Human Metapneumovirus in A 4.5-Month-Old Infant With

Abstract

Lower respiratory tract infections (LRTI) are mostly caused by respiratory syncytial virus (RSV), influenza, parainfluenza, rhinovirus and adenovirus. In recent years human other viruses such as human metapneumovirus (hMPV), parainfluenza 4 and bocavirus also have been reported to cause LRTI. Coinfection of more than one virus in childhood can develop bronchiolitis in children. In this study, we report a case of bronchiolitis developed by coinfection of hMPV and influenza A viruses in a 4.5-month-old male baby who admitted to our hospital with the fever and cough.

İnsan Metapnömovirüs’e İnfluenza A Virüsünün Eşlik Ettiği 4.5 Aylık Süt Çocuğunda Alt Solunum Yolu Enfeksiyonu

Abstract

Alt solunum yolu enfeksiyonları (ASYE) çoğunlukla respiratuvar sinsisyal virüs (RSV), influenza, parainfluenza, rhinovirüs ve adenovirüs kaynaklıdır. Ancak, son yıllarda bu virüslere ek olarak insan metapnömovirüs (iMPV), parainfluenza 4 ve bocavirüs gibi virüslerinde ASYE’ye sebep olduğu gösterilmiştir. Çocukluk çağında birden fazla virüsün ko-enfeksiyonu ile bronşiolit geliştiği unutulmamalıdır. Bu çalışmamızda, ateş ve öksürük şikâyeti ile hastanemize başvuran 4.5 aylık erkek bir bebekte iki farklı virüsün (iMPV ve influenza A) ko-enfeksiyonu sonucu gelişen bronşiolit olgu sunumu anlatılmıştır.
