Efficacy of rapid antigen self-testing for SARS-CoV-2 screening:Real-world evidence from a prospective cohort study

Genes & Diseases 2024年第5期11卷 88-90页

Antigen rapid diagnostic tests(Ag-RDTs)have been considered and implemented as an important diagnostic and screening tool to identify SARS-CoV-2 infections in community settings.1 Ag-RDTs are less sensitive,particularly in asymptomatic populations,compared with laboratorybased viral nucleic acid amplification tests(NAATs)such as reverse transcription polymerase chain reaction(RT-PCR).2 However,taking into account the facts that Ag-RDTs are effective for identifying most contagious individuals,they are faster and less expensive than RT-PCR,as well as that RT-PCR could produce positive results for weeks to months after the infection,2 WHO recommends Ag-RDTs be offered as COVID-19 self-testing for screening purposes in addition to professionally administered testing services regardless of the community transmission level.

中华民族共同体的形成,离不开各民族长期的交往交流交融实践。村落共同体作为中华民族共同体的有机组成,包含着一套既具象又抽象的空间生产逻辑。华丰坪村地处“三江并流”区域腹地,汉藏共居,随元明清时期边疆治理制度及滇藏茶马古道发展而逐渐形成。本文通过梳理该村从“徐加贡”“叙昌紫塘”“叙农巴”“换夫坪村”“华丰坪村”到“华丰坪社”的地名演进,探讨了汉族迁入后与当地藏族的互动关系,村里同一庙祠中汉族“五庙”与藏族“格萨尔拉康”的有机联结,呈现出汉藏文化交融的村落空间、信仰空间、记忆空间,形象阐释了村落共同体“合之又合”的空间生产逻辑及其“和合共生”的动力机制,为探索中华民族共同体的和融路径提供一个具体的范例。
