2022年1月5日，一名在英格兰家中饲养大量鸭子的人被证实感染高致病性甲型禽流感（H5N1）。该患者仍无症状。2021年12月22日，20只活禽样本中有19只确认感染H5N1。全面的接触者追踪（n = 11）显示没有额外的原发病例或继发性传播。对受感染者进行积极监测对于查明病例至关重要。鉴于禽流感流行病学的变化，无症状拭子有助于完善公共卫生风险评估，并促进病例管理。
On 5 January 2022, high pathogenicity avian influenza A(H5N1) was confirmed in an individual who kept a large flock of ducks at their home in England. The individual remained asymptomatic. H5N1 was confirmed in 19/20 sampled live birds on 22 December 2021. Comprehensive contact tracing (n = 11) revealed no additional primary cases or secondary transmissions. Active surveillance of exposed individuals is essential for case identification. Asymptomatic swabbing helped refine public health risk assessment and facilitated case management given changes in avian influenza epidemiology.
