摘要

Objective:To analyze the epidemiological and clinical characteristics of foreign-imported patients infected with SARS-CoV-2 in Chengdu City.Methods:A total of 290 foreign-imported patients infected with SARS-CoV-2 and discharged from Public Health Clinical Center of Chengdu were included in our study,they were divided into asymptomatic infection group(131 cases)and confirmed cases group(159 cases)in order to compare the epidemiology,clinical characteristics and laboratory tests between two groups.Multi-factor logistic regression analysis was used to investigate the influence factors of becoming a dominant infection after infected with SARS-CoV-2.Results:Among the 290 cases aged from 2 months to 68 years old,83.4%were males,62.1%came from Asia,and 43.8%were complicated with fatty liver disease,the age group of 14-49 years old had the largest number(247 cases).80.5%confirmed case group cases were general type,there was only 1 severe patient.Hospital stays in asymptomatic infection group was shorter than that in confirmed cases group,lymphocyte count,CD4+T count,CD8+T count,CD4+T/CD8+T creatine kinase in two groups half a month after discharge were relatively lower than those on admission,and alanine aminotransferase,aspartate aminotransferase,albumin,lactate dehydrogenase,creatine kinase isoenzyme were relatively higher than those on admission(P<0.05).Logistic regression analysis showed that increased age,decreased lymphocyte count on admission and increased lactate dehydrogenase on admission were associated with dominant infection.Chest CT of 13 general type cases indicated an increase in lesions compared with that at discharge and 3 of them had re-detectable positive RNA test.Conclusion:The majority of foreign-imported cases in Chengdu are mainly from Asia,fewer of them are severe patients.In the early stage of recovery,some SARS-CoV-2 infected patients still have intermittent viral replication.Early isolation and early treatment of imported patients is not only conducive to epidemic prevention and control,but also may change the natural course of the disease.
