ObjectiveTo explore the epidemiological and clinical characteristics of patients infected with novel coronavirus, and to provide references for scientific prevention and control. MethodA total of 114 patients infected with novel coronavirus admitted to the Ninth People′s Hospital of Dongguan from January 23 to March 16, 2020, were selected as the research objects. The relative data of patients in the history of epidemiology, basic information, incubation period, hospital stays, clinical symptoms and signs, laboratory test results, CT examination results etc. were collected and statistically analyzed. ResultsAmong the 114 patients, 77 patients who returned from epidemic areas in Hubei Province (including Wuhan) or had a history of sojourn in epidemic areas within 14 days accounted for 67.5%, 35 patients who had a history of close contact to confirmed cases accounted for 30.7%, 1 patient who did not have a definite history of sojourn and close contact in epidemic areas accounted for 0.9%, and 1 patient imported from abroad accounted for 0.9%. 15 onset cases belonged to cluster disease, including 62 patients, among which 14 onset cases belonged to family cluster disease, including 56 patients. The patients had no specific clinical symptoms, of which 47 cases with cough (41.2%), 41 cases with fatigue (36.0%), 34 cases with expectoration (29.8%), 33 cases with headache (28.9%), and 27 cases with fever (23.7%). There were 16 mild patients (14.0%), 66 ordinary patients (57.9%), 10 severe patients (8.8%), 8 critical patients (7.0%), and 14 patients (12.3%) with asymptomatic infection. There were statistically significant differences in the age and hospitalization time of patients in different clinical types (P＜0.05), but the differences in gender and incubation period were not statistically significant (P＞0.05). There were statistically significant differences in the white blood cell counts, neutrophil counts, and CRP levels between the patients in different clinical types and the patients with asymptomatic infections (P＜0.05), but there were no statistically significant differences in lymphocyte counts and PCT level between them (P＞0.05). The chest CT examination of patients with asymptomatic infection (14 cases) and mild patients (16 cases) showed no abnormalities. The chest CT examinations of ordinary, severe and critical patients (84 cases) presented in patchy ground glass-like changes. ConclusionThe majority of patients infected with novel coronavirus in Dongguan are imported cases. The onset of family cluster disease is common. The patients have no specific clinical symptoms and most of them interpret in ordinary type. The chest CT examinations of ordinary, severe and critical patients all express patchy or ground glass-like changes.
