摘　　要：2024年2月,东莞市某镇发生一起人感染鹦鹉热衣原体疫情。为确定疫情源头,防止疫情蔓延,消除疫情传播风险,对确诊病例的疑似暴露点、活禽来源地三鸟批发市场和农贸市场及患者在生态园游玩线路开展畜禽间(野鸟)鹦鹉热衣原体流行病学调查。调查结果显示:在疑似暴露点和生态园游玩线路上采集的家禽、野鸟样品中未检出鹦鹉热衣原体核酸阳性,但在活禽来源地三鸟批发市场3个活禽档采集样品中检测到8份核酸阳性,阳性率为6.67%;在活禽来源地农贸市场2个水禽档口采集样品中检测到7份核酸阳性,阳性率为8.75%。调查认为:虽然在疑似暴露点未检出阳性样品,但在活禽来源地农贸市场和三鸟批发市场均检出鹦鹉热衣原体核酸阳性样品,疑似暴露点仍然存在一定鹦鹉热衣原体传播和感染风险;由于疑似暴露点存在栏舍分布不合理、活禽来源复杂、不同批次和不同禽类混养、人员防范意识薄弱等,进一步增加了人感染鹦鹉热衣原体的风险。In February 2024,a human infection with Chlamydia psittaci occurred in a town in Dongguan City.In order to determine the source of the epidemic,prevent its spread,and eliminate the risk of epidemic transmission,an epidemiological investigation of Chlamydia psittaci(Chlamydia psittaci)among livestock and poultry(wild birds)was conducted on suspected exposure points of confirmed human cases,sources of live poultry(1 three bird wholesale market,2 surrounding agricultural markets),and recent visits of patients to ecological parks.The survey results showed that no positive samples of Chlamydia psittaci nucleic acid were detected in poultry and wild bird samples collected at suspected exposure points and amusement routes in ecological parks.However,8 positive samples of nucleic acid were detected in samples collected from three live bird stalls in the Poultry Market,the source of live poultry,with a positive rate of 6.67%;Seven nucleic acid positive samples were detected in the samples collected from two waterfowl stalls in the source of live poultry,with a positivity rate of 8.75%.The investigation found that although no positive samples were detected at suspected exposure points,positive samples of Chlamydia psittaci nucleic acid were detected in both the agricultural market and Sanniao wholesale market in the source of live poultry,indicating a certain risk of Chlamydia psittaci transmission and infection;Suspected exposure sites have unreasonable distribution of pens,complex sources of live poultry,mixed breeding of different batches and types of poultry,and weak awareness of personnel prevention,further increasing the risk of human infection with Chlamydia psittaci.
