Abstract

Human metapneumovirus (hMPV) is a recently recognized human respiratory pathogen, which is known to be associated with upper and lower respiratory tract infections mainly in children, immunocompromised patients, and the elderly. The clinical manifestations of hMPV infections are similar to those of the human respiratory syncytial virus infection, which range from mild upper respiratory tract infection to severe bronchiolitis and pneumonia. Recently, hMPV has come to be thought of as the cause a similar spectrum of disease in adults as that seen in children; however, most of the reports of hMPV infections have focused on infection in children. We report a case of severe hMPV pneumonia requiring mechanical ventilation in an immunocompetent adult in Korea.

Figure 1
(A) The initial chest radiograph showed bilateral diffuse hazziness in both lower lung fields. (B) After a few hours, bilateral diffuse consolidation on chest radiograph progressed rapidly.
