title: Clinical data analysis of 19 cases of community-acquired adenovirus pneumonia in immunocompetent adults.
abstract: The aim of this study was to investigate the characteristics of clinical manifestations, laboratory tests and imaging changes of community-acquired adenovirus pneumonia in immunocompetent adults. A retrospective study was performed on 19 adult community-acquired adenovirus pneumonia cases in Yantai, whereby the clinical data were collected and analyzed. Of 19 cases, 14 (73.68%) had fever and 17 (89.47%) had cough symptoms. Moreover, 14 cases (73.68%) had normal white blood cell counts, while 11 cases (57.89%) exhibited a reduction in lymphocyte proportion. Among the 19 cases, 17 cases exhibited lesions in a single lung, while 2 cases involved bilateral lungs. The lesions predominantly exhibited ground glass-like changes. The clinical manifestations of adult community-acquired adenovirus pneumonia patients with normal immune functions were mild, with such presenting symptoms as fever, cough, and sputum; most patients did not exhibit high levels of white blood cells or low lymphocyte counts, and the imaging features (ground glass-like effusion) were indicative of single-lung involvement.
