| Objective 1)To systematically and comprehensively investigate the epidemiological characteristics and sources of foreign-imported COVID-19 patients in Gansu Province,so as to carry out targeted prevention and control work in key populations and areas.2)to analyze the characteristics,clinical treatment and laboratory findings of imported COVID-19 patients in Gansu province,and provide guidance for the subsequent prevention,treatment and rehabilitation of COVID-19.3)Analyze the prevention and control policies,human resources allocation and related measures for the foreign-imported COVID-19 in Gansu Province,evaluate the effects,and provide reference for the regular epidemic prevention and control.Methods Collect imported COVID-19 cases in Gansu Province,and analyze the epidemiological characteristics of foreign-imported COVID-19 cases in Gansu Province using descriptive statistical analysis.2)Retrospective investigation method,collecting foreign-imported epidemic-related data and policies and measures from Gansu Provincial Health Commission,Gansu Provincial Center for Disease Control and Prevention,Gansu Provincial People’s Government official website and provincial designated treatment hospitals,and retrospectively summarize and analyze the Clinical manifestations,laboratory examinations and clinical treatment of foreign-imported COVID-19 patients.3)Comparative analysis,to compare the work related to the prevention and control of the imported epidemic situation of COVID-19 in other provinces in China,and to analyze the differences between the prevention and control of the foreign-imported epidemic in Gansu Province.4)Inductive synthesis method,through the analysis and summary of the prevention and control measures and treatment of imported COVID-19 epidemic situation in Gansu Province,and put forward suggestions and strategies for further improvement,to provide reference for the prevention and control of the imported epidemic situation in Gansu Province and even the whole country.Results As of December 31,2020,a total of 181 cases of COVID-19 were reported in Gansu Province,of which 90(49.7%)were foreign-imported COVID-19 cases.Among the imported COVID-19 patients in Gansu Province,41 cases were mild,45 cases were common type,4 cases were severe type,and there were no severe patients.80 patients were in good health and 10 patients were accompanied with basic diseases(hypertension,diabetes,etc.).The majority of patients were overseas students(53.3%),followed by migrant workers(20%),farmers(8.9%)and freelancers(8.9%).The average age of the imported patients was 27.38±11.1,ranging from 4 months to62 years old.There were 71 males and 19 females with a sex ratio of 4:1.The most common clinical symptoms included pharyngeal discomfort(33.3%),cough(23.3%),perceived fatigue(21.1%),and fever(20.0%).A few patients have symptoms such as dizziness,headache,muscle soreness and mild diarrhea.Laboratory examination results showed that hemoglobin,which is the most abnormal blood test index,was increased(37 cases,41.1%),white blood cell count decreased(15 cases,16.7%),lactate dehydrogenase increased(15 cases,16.7%)and neutrophils count decreased(11 cases,12.2%).The results of chest CT examination showed that 37 patients had no abnormalities,and 53 patients had different degrees of abnormalities in their lungs,mainly small nodules and ground glass density shadows.The location of lung involvement in patients was mainly unilateral(37.8%).The treatment of 90 imported patients was mainly antiviral and traditional Chinese medicine.Some patients were treated with antibiotics or glucocorticoids due to individual differences,and the treatment effect was remarkable.Now the patients have been cured and discharged from the hospital with normal indicators.The results of statistical analysis showed that there were significant differences in some clinical symptoms(pharynx discomfort,conscious fatigue and fever)among patients with different clinical types.Mild patients were mainly pharyngeal discomfort(48.8%).Common type patients were mainly cough and no obvious characteristics,both accounted for 31.1%.There were significant differences in imaging features(no obvious abnormality and ground glass density shadow)in patients with different clinical types.the common type of patients was mainly small nodule density shadow.There were significant differences in treatment methods among patients with different clinical types.Mild and common patients were mainly treated with antiviral and traditional Chinese medicine(85.4% and 66.7%),and severe patients were mainly treated with antiviral therapy(50%).An analysis of the manpower input by Gansu Province in responding to foreign-imported epidemics showed that as of December 31,Gansu Province has transferred medical personnel from all provinces,cities,prefectures,and counties,and sent a total of 15 batches of personnel,totaling 1362 medical staff to carry out the prevention and control of the imported epidemic.Analysis of the policies and measures for the prevention and control of foreign imported epidemics in various provinces,Shanghai issued 34 items,29 items in Guangdong Province,26 items in Gansu Province,24 items in Heilongjiang Province and 21 items in Inner Mongolia.The main features of Gansu’s measures focus on the establishment of a centralized isolation point for overseas returnees in Lanzhou New area,the implementation of "whole process closed-loop" management for overseas personnel,and the use of traditional Chinese medicine for most patients,supplemented by western medicine.Analyzing the number of imported confirmed cases and the cure rate in the sample provinces,the number of confirmed cases from high to low was 1167 in Shanghai,650 in Guangdong,389 in Heilongjiang,259 in Inner Mongolia,and 90 in Gansu.The cure rates from high to low were Gansu Province(100%),Heilongjiang Province(100%),Guangdong(95.7%),Inner Mongolia(95.4%)and Shanghai(91.7%).Conclusions This study analysis the whole process of the fight against the imported COVID-19 epidemic in Gansu,starting from the three aspects of epidemic history,prevention and control,and treatment.Taking the introduction of policies and measures for prevention and control of the imported epidemic situation,the intensity of implementation and the effect of treatment as indicators,and makes a comparison with other provinces(cities)in China.To study the core issues such as the response speed,decision-making arrangements,measures and implementation,prevention and control effectiveness of Gansu in response to the imported COVID-19 epidemic.Overall,Gansu Province has established the “Chinese standard” for the centralized isolation and screening of entry personnel across the country and accumulated the “Gansu experience” in the fight against the foreign-imported epidemic situation.Provide a reference for further improving the governance system for dealing with major public health emergencies and improving the management ability to deal with major public health emergencies.However,given that this study currently only focuses on the data of Gansu Province,it is urgent to expand the sample size and conduct a comparative analysis with large multi-center samples across the country to provide high-quality research evidence to support decision-making,to provide scientific evidence for the regular prevention and control of foreign-imported epidemics China. |
