Abstract:
Objective To investigate the clinical characteristics of a clustering infection caused by human adenovirus-B type 7 (HAdV-B7) which occurred in one military camp located at the southeastern coastal region in January 2014.Methods All clinical characteristics of the 70 patients were collected for analysis,including clinical symptoms and signs,chest computer tomography (CT) scans and laboratory results.Throat swabs were collected and real time polymerase chain reaction (RT-PCR) was performed to detect viral nucleotide.Results The prominent symptoms of these patients with HAdV-B7 infection included fever (100.0％,70/70),cough (82.9％,58/70),productive cough (72.9％,51/70) and sore throat (61.4％,43/70).All patients showed posterior pharyngeal wall linear congestion with ovoid follicle.Fifty-four (77.1 ％) patients had enlarged tonsils and 46 (65.7 ％) patients had tonsils covered by white secretions.Fifty-eight (82.9 ％) patients had pharyngeal follicular hyperplasia.Fifty-one (72.9 ％) patients had abnormalities on chest radiograph,including lung-marking fuzzy,pulmonary interstitial inflammation and parenchymal serous exudation.Of the 54 throat swabs from patients,34(63.0％) were identified as HAdV-B7.All patients were cured.Conclusions The clinical features of patients with HAdV-B7 infection are different from other viral infection.HAdV-B7 is easy to cause clustering infection in particular populations.Early detection and early intervention are needed to avoid exacerbation and transmission.
