摘要
目的 研究长春市猴痘病例的临床及流行病学基本特征,为今后的猴痘疫情防控工作提供参考.方法 选取长春市医疗机构发现的18例猴痘病例开展流行病学调查,分析病例的三间分布、高危暴露特点、就诊情况及临床表现,并采集病例咽拭子、痘疱液擦拭物标本进行核酸检测.结果 病例多为未婚青年男性、男男性行为人群(MSM);疾病通过同性接触的人传人方式传播,感染来源为非固定性伴,暴露地点较为隐匿,潜伏期平均值为9.06d;病例发现方式以主动就诊和密切接触者排查为主;首发症状以发热和皮疹为主,分别为38.89％(7/18)和50％(9/18);所有病例均出疹,部位涉及全身,无特殊顺序;发病到确诊的时间平均为5.88 d;病例多为HIV感染者,为50％(6/12).结论 猴痘疫情在MSM人群中流行,通过男男性接触经人传人方式传播;症状上一般为发热、皮疹、腹股沟淋巴结肿大,多数患者发病后能及时就医,部分患者初次就医难以确诊,导致病例无法及时发现并管控,疫情调查处置存在一定难度.
Abstract
This study conducted an epidemiological investigation of 18 mpox cases in Changchun City,to provide a refer-ence for the investigation and disposal of psittacosis cases,as well as prevention and control.Epidemiologie data were collected through field epidemiologic investigation,and throat swabs and acne blister fluid swab samples were collected for nucleie acid testing.The majority of cases were unmarried young men who have sex with men(MSM).Transmission occurred through ho-mosexual contact with casual sexual partners at relatively discreet exposure sites,with an average incubation period of 9.06 days.Active medical treatment and close contact screening were the main methods used to identify cases.The first symptom in the patient were fever(38.89％,7/18)and rush(50％,9/18).Rashes were present in all cases,affecting various body parts without specific order;the average time from onset to diagnosis was 5.88 days.Most cases had HIV infection(50％,6/12).Most patients can take the initiative to seek medical treatment after the onset of a disease.However,some face difficulties in re-ceiving an accurate diagnosis during their first visit to healthcare facilities,which may delay the identification and management of the condition.
