초록

Objectives: Respiratory virus infections are the most common disease among all ages in all parts of the world and occur through airborne transmission. The purpose of this study was to detect and quantitate human respiratory viruses in residential environments. Methods: Air samples were collected from the residential space of apartments in the Seoul/Gyeonggi-do area. The samples were collected from indoor and outdoor air. Among respiratory viruses, influenza A virus, influenza B virus, parainfluenza virus, metapneumovirus, respiratory syncytial virus, and adenovirus were investigated by multiplex polymerase chain reaction. Among the virus-positive samples, we performed adenovirus quantification by real-time polymerase chain reaction. Results: Virus detection rates were 44.0%, 3.8%, 3.4%, and 17.3% in spring, summer, autumn, and winter, respectively. The virus detection rate was higher in winter and spring than in summer and autumn. Adenovirus was most commonly detected, followed by influenza A virus and parainfluenza virus. Virus distribution was not significantly different between indoor and outdoor environments. Conclusions: Although virus concentrations were not high in residential environments, residents in houses with detected viruses may have an increased risk of exposure to airborne respiratory viruses, especially in winter and spring.
