text-indent: 2em; visibility: visible;">当前，国内疫情呈现多点散发态势，我市本轮疫情毒株经市疾控中心病毒基因测序显示，为奥密克戎变异株BA.5.2进化分支。10月21日，华中科技大学同济医学院公共卫生学院魏晟教授接受记者采访时指出，从武汉本轮疫情中感染者的发病情况来看，主要是上呼吸道感染为主，BA.5.2变异株容易大量增殖和排毒，潜伏期短，传播速度更快。鉴于该毒株的很强传染性，<span style="margin: 0px;

text-align: justify; text-indent: 2em; visibility: visible;">“综合近期国内外有关奥秘克戎变异株流行病学特点及代际传播间隔时间的研究结果来看，与既往毒株相比，BA.5.2进化分支具有两大特点。”魏晟指出，一是病毒载量较高，传染性极强。根据有关研究报道，该毒株的基本再生数为18.6，通俗地说就是平均1个感染者在其传染期内能够传染给18人，极易造成大面积传播，疫情处置、控制难度较以往成倍增加。</section><section style="margin: 0px 8px;

max-width: 100%; box-sizing: border-box !important; overflow-wrap: break-word !important; text-align: justify; text-indent: 2em; visibility: visible;">二是平均潜伏期较短，本轮疫情BA.5.2进化分支观察的潜伏期平均2~3天，多为2天，最短仅为1天，且无症状感染者比例较高，导致病例早发现、早控制难度增加。因此很容易“潜行”在人群中，造成隐匿性的传播。</section><section style="margin: 0px 8px;

overflow-wrap: break-word !important; text-align: justify; text-indent: 2em;">“鉴于本轮疫情毒株BA.5.2的极强传染性，科学佩戴口罩、不扎堆不聚集，可以有效降低传播风险，防止疫情扩散蔓延。”魏晟强调，疫情防控关键期，市民朋友应积极配合现阶段各项防控措施，非必要不到人员密集场所，尽量不聚餐聚会，增强个人防护意识，坚持勤洗手、常通风、分餐制、用公筷、保持1米线社交距离。</section><section style="margin: 0px 8px;

overflow-wrap: break-word !important; text-align: justify; text-indent: 2em;">其次，市民朋友还要积极参加常态化核酸检测。奥密克戎变异毒株BA.5.2在短时间内能快速传播，隐匿性强。由于存在感染病毒和病毒能够检出之间的时间差，因此只有在短期内反复检测，才能以最快的速度检出感染者。广大市民积极参与多轮常态化核酸检测是十分必要的。务必做到“应检尽检”，才可能以最快的速度做到“动态清零”，防控疫情蔓延。</section><section style="margin: 0px 8px;
