A 41-year-old man in Jiangsu has been confirmed as the first human case of infection with the H10N3 strain of bird flu, although health officials in China said the risk of large-scale spread remained low.
 

The man, a resident of the city of Zhenjiang, went to hospital on 28 April after developing a fever and other symptoms, China’s national health commission said.
 

He was diagnosed as having the H10N3 avian influenzavirus on 28 May, the commission said though it did not give details about how the man had been infected with the virus. The man was stable and ready to be discharged from hospital. Medical observation of his close contacts had not found any other cases.
 

H10N3 is a low pathogenic, or relatively less severe, strain of the virus found in poultry, and the risk of it spreading on a large scale is very low, the commission added.
 

Many different strains of avian influenza are present in China and some sporadically infect people, usually those working with poultry. There have been no significant numbers of human infections with bird flu since the H7N9 strain killed about 300 people during 2016-2017.
 

No other cases of human infection with H10N3 have previously been reported globally, the commission said.
 

江苏发现一例人感染H10N3禽流感病例!全球首例

国家卫生健康委通报,江苏省发现一例人感染H10N3禽流感病例。
 

患者,男,41岁,现居江苏镇江。
 

4月23日出现发热等症状,4月28日因病情加重收入当地医疗机构救治。目前,患者病情稳定,基本达到出院标准。5月28日,中国疾控中心对江苏省送来的患者标本开展全基因组序列测定,结果为H10N3病毒阳性。
 

江苏省对所有密切接触者进行医学观察,在当地开展应急监测,均未发现异常情况。
 

国家卫生健康委已指导江苏省按照相关方案开展防控,并组织专家风险评估。专家评估认为,病毒全基因分析显示,H10N3病毒为禽源性,未具备有效的感染人的能力。全球既往未见H10N3人间病例报道,禽间H10N3病毒对禽呈低致病性。此次疫情为一次偶发的禽到人的跨种属传播,发生大规模传播流行风险极低。
 

专家建议,公众在日常生活中应避免接触病死禽,尽量避免直接接触活禽;注意饮食卫生,提高自我防护意识,出现发热及呼吸道症状,应戴上口罩,尽快就医。
