RESUMO
Objective@#To investigate the hepatitis C prevention and control knowledge among clinicians in Jiaxing City, Zhejiang Province, so as to provide the evidence for intensified training and improved diagnosis and treatment of hepatitis C among clinicians.@*Methods@#In November, 2021, clinicians were sampled using a stratified random sampling method from a city-level and a county (district)-level hepatitis C designated hospital in Jiaxing City. A questionnaire survey was performed using the Questionnaire for Hepatitis C Prevention and Control Knowledge among Clinicians, and the awareness of basic knowledge, professional knowledge and related knowledge about hepatitis C prevention and control among clinicians were descriptively analyzed. @*Results@# A total of 186 questionnaires were allocated and 179 valid questionnaires were recovered, with an effective recovery rate was 96.24%. The respondents included 107 men (59.78%) and 72 women (40.22%) and had a mean age of (37.06±9.46) years. There were 107 respondents with a bachelor degree (59.78%), 56 with junior professional titles (31.28%), and 170 from non-infectious disease departments (94.97%). The awareness of basic hepatitis C prevention and control knowledge was 96.09%, and the awareness of “Transfusion of blood containing hepatitis C virus may acquire hepatitis C” was high (98.88%), and the awareness of “Hepatitis C can be cured” was low (77.09%). The awareness of professional hepatitis C prevention and control knowledge was 3.91% to 100.00%, and the awareness of “Pathogens of hepatitis C” (100.00%) and “Recommended screening populations for hepatitis C” (86.59%) was high, while the awareness of “There are two categories of hepatitis C cases: clinically diagnosed cases and confirmed cases” (3.91%) and “Clinical diagnosis of hepatitis C: positive anti-HCV antibody + any one of abnormal liver function or epidemiological history or clinical symptoms” (3.91%) was low. The awareness rates of “The state has included antiviral agents against hepatitis C into medical insurance” was and “Antiviral agents against hepatitis C are reimbursed in outpatient and inpatient departments of our hospital” were 81.56% and 59.78%, respectively. There were 69 clinicians participating hepatitis C-related training within one year (38.55%), and the awareness of clinicians that had participated in hepatitis C-related training had a higher awareness rate of basic hepatitis C prevention and control knowledge than those without participation (100.00% vs. 93.64%, P<0.05).@*Conclusion@#The awareness of basic hepatitis C prevention and control knowledge is high among clinicians in Jiaxing City; however, the training on diagnosis and classification criteria of hepatitis C and related medical insurance policy require to be improved.
RESUMO
Objective@#To perform an epidemiological survey of the first case with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Pinghu City of Jiaxing City, Zhejiang Province on March 13, 2022, so as to provide insights into the management of coronavirus disease (COVID-19) epidemics. @*Methods@#According to the requirements of the Protocol on Prevention and Control of COVID-19 (8th Edition), epidemiological investigations were performed among 39 cases with SARS-CoV-2 infections in Pinghu City from March 13 to 20, 2022. Cases' demographics, clinical symptoms, history of immunization and exposure were collected, and close contacts were identified. Pharyngeal swabs were sampled from infected cases for detection of SARS-CoV-2 nucleic acid and whole-genome sequencing, and the source of infection and transmission route were investigated. @*Results@#The index case for this COVID-19 epidemic was an imported case from Shanghai Municipality, who infected 6 persons via aerosol transmission when playing in the badminton venue of Pinghu National Fitness Center on March 9; subsequently, one of these infected cases infected another 18 persons when playing in the badminton venue of Jiadian Village Resident's Fitness Center in Zhapu Township on March 12. Sixteen confirmed cases were reported, and all cases were mild; another 23 asymptomatic cases were diagnosed, with no death reported. This epidemic occurred from March 11 to 20, with 3 generations of spread and a median incubation period of 3 days. The SARS-CoV-2 infected cases had a median age of 33.5 (interquartile range, 12.0) years and included 36 cases with a history of COVID-19 vaccination. There were 16 cases with fever, cough, runny nose and sore throat, and 13 cases with imaging features of pneumonia. The effective reproductive number (Rt) of the COVID-19 epidemic was 7.73 at early stage, and was less than 1 since March 21. Whole-genome sequencing identified Omicron BA.2 variant among 33 cases, which had high homology with the index cases. @*Conclusion@#This epidemic was a cluster of COVID-19 caused by imported Omicron BA.2 variant infection from Shanghai Municipality, and the COVID-19 transmission was mainly caused by indoor aerosols.
