!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。即使已经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。</span></p><p style="outline: 0px;max-width: 100%;font-family: -apple-system,

!important;">（2）做好个人健康监测。在有疑似新冠肺炎症状，例如发热、咳嗽、呼吸短促等症状出现时，及时监测体温，主动就诊。</span></p><p style="outline: 0px;max-width: 100%;font-family: -apple-system, BlinkMacSystemFont, Helvetica Neue, PingFang SC,

!important;">（3）减少非必要出入境。短短数天时间，多个国家和地区陆续报告奥密克戎变异株输入，我国也面临该变异株输入的风险，并且目前全球对该变异株的认识仍有限。因此，应尽量减少前往高风险地区，并加强旅行途中的个人防护，降低感染奥密克戎变异株的机会。</span></p><p></p><section style="margin-right: 16px;margin-bottom:
