1 INTRODUCTION
Human adenovirus (HAdV) is a common pathogen among children and adults and HAdV infections can range in severity from unapparent clinical illness to severe, life-threatening disease, which vary depending on the cell tropism of the viruses. Pneumonia caused by HAdV7 infection commonly associated with lower respiratory tract disease is usually severe. According to the last global survey, approximately one-fifth of all HAdV infections reported to the WHO was attributed to HAdV7, and in a few cases can lead to death.1-3
HAdV7 outbreaks typically occur and the virus can spread rapidly in closed environments, such as hospital wards, military barracks, and chronic care facilities.4-7 In the study, a HAdV7 outbreak in a tertiary hospital that led to a death case and nosocomial infection was reported.
