letter-spacing: 0.544px; box-sizing: border-box !important;'>奥密克戎变异株最早于2021年11月27日输入我国香港，12月9日首次输入我国内地。<p style='outline: 0px; max-width: 100%; font-family: -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; letter-spacing: 0.544px; box-sizing: border-box !important;'> <p style='outline: 0px; max-width: 100%; font-family: -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; letter-spacing: 0.544px; box-sizing: border-box !important;'>2.奥密克戎变异株的传播力<p style='outline: 0px; max-width: 100%; font-family: -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; letter-spacing: 0.544px; box-sizing: border-box !important;'> <p style='outline: 0px; max-width: 100%; font-family: -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; letter-spacing: 0.544px; box-sizing: border-box !important;'>多国流行病学数据提示，奥密克戎变异株传播能力较其他变异株有所增强。世界卫生组织于2021年12月23日关于奥密克戎的简报显示，其家庭续发率为15.8%，高于德尔塔的10.3%。英国卫生安全局数据显示，2021年12月19日至20日，伦敦90%和英格兰76%的新冠肺炎病例为奥密克戎变异株感染。美国疾控中心网站数据显示，在2021年12月26日至2022年1月1日的一周内，美国本土95.4%的新冠肺炎病例为奥密克戎变异株感染。<p style='outline: 0px; max-width: 100%; font-family: -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; letter-spacing: 0.544px;

letter-spacing: 0.544px; box-sizing: border-box !important;'>3.现有疫苗对预防奥密克戎变异株感染的效果<p style='outline: 0px; max-width: 100%; font-family: -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; letter-spacing: 0.544px; box-sizing: border-box !important;'> <p style='outline: 0px; max-width: 100%; font-family: -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; letter-spacing: 0.544px; box-sizing: border-box !important;'>目前已有的研究结果显示，奥密克戎变异株对现有疫苗并未完全出现免疫逃逸；现有疫苗对奥密克戎变异株仍有一定的保护效果，但对其预防感染的能力有所下降；未发现奥密克戎变异株引起重症率和死亡率的上升，针对奥密克戎变异株，现有疫苗预防重症和死亡仍有效果。<p style='outline: 0px; max-width: 100%; font-family: -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; letter-spacing: 0.544px;

letter-spacing: 0.544px; box-sizing: border-box !important;'>鉴于奥密克戎变异株在全球的快速流行趋势，近期美国、英国、俄罗斯和欧盟等均建议民众加强日常卫生防护（洗手、戴口罩和安全社交距离），卫生部门加强疾病监测、疫苗接种，尤其是为一线医护人员注射新冠病毒疫苗加强针。<p style='outline: 0px; max-width: 100%; font-family: -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; letter-spacing: 0.544px; box-sizing: border-box !important;'> <p style='outline: 0px;

letter-spacing: 0.544px; box-sizing: border-box !important;'>我国“外防输入，内防反弹”总策略和“动态清零”总方针，对奥密克戎变异株仍然有效。中国疾控中心已针对奥密克戎变异株建立了特异性核酸检测方法，并持续针对可能的输入病例及关联的本土病例开展病毒基因组监测，有利于及时发现可能输入或关联本土的奥密克戎变异株。<p style='outline: 0px; max-width: 100%; font-family: -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; letter-spacing: 0.544px; box-sizing: border-box !important;'> <p style='outline: 0px; max-width: 100%; font-family: -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; letter-spacing: 0.544px; box-sizing: border-box !important;'>7.世界卫生组织应对奥密克戎变异株的建议<p style='outline: 0px; max-width: 100%; font-family: -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif;

letter-spacing: 0.544px; box-sizing: border-box !important;'>世界卫生组织建议各国加强新冠肺炎病毒的监测、报告与研究工作，采取有效的公共卫生措施阻断病毒传播。建议个人在公共场所至少保持1米距离、佩戴口罩、开窗通风、保持手清洁、对着肘部或纸巾咳嗽或打喷嚏、接种疫苗等，同时避免去通风不良或拥挤的地方。目前，所有变异株都可能导致重症或死亡。因此，预防病毒传播始终是关键，新冠病毒疫苗对减少重症和死亡仍然有效。<p style='outline: 0px; max-width: 100%; font-family: -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; letter-spacing: 0.544px;

letter-spacing: 0.544px; box-sizing: border-box !important;'>（1）戴口罩仍然是阻断病毒传播的有效方式，对于奥密克戎变异株同样适用。即使在完成全程疫苗接种和接种加强针的情况下，也同样需要在室内公共场所、公共交通工具等场所佩戴口罩。此外，还要勤洗手和做好室内通风。<p style='outline: 0px; max-width: 100%; font-family: -apple-system, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; letter-spacing: 0.544px; box-sizing: border-box !important;'> <p style='outline: 0px;
