86);letter-spacing: normal;font-size: 16px;font-family: Helvetica Neue, Helvetica, Hiragino Sans GB, Microsoft YaHei, Arial, sans-serif;">张文宏介绍，根据数据显示，</span><span style="letter-spacing: normal;font-size: 16px;font-family: Helvetica Neue, Helvetica, Hiragino Sans GB, Microsoft YaHei, Arial, sans-serif;color: rgb(0, 122, 170);"><strong>如果新冠病毒发生变异，6个月后会慢慢出现二次感染，一般规模不大。但如果新病毒的变异，有效突破了人体应对前一波病毒形成的免疫屏障，第二波就会形成感染高峰。</strong></span></p><p style="margin: 0px;text-indent: 2em;line-height: 1.75em;"><span style="font-family: Helvetica Neue, Helvetica, Hiragino Sans GB, Microsoft YaHei, Arial, sans-serif;font-size: 16px;color: rgb(86, 86, 86);letter-spacing: normal;"><br/></span></p><p style="margin: 0px;white-space:

86);letter-spacing: normal;">张文宏解释，二次感染主要有两种情况：一是在第一波疫情中感染过的人免疫力逐渐衰减，二是在第一波疫情中未感染的人被感染。根据监测数据，目前我国很多感染者的情况都是后者。</span></p><p style="margin: 0px;white-space: normal;text-indent: 2em;line-height:

16px;color: rgb(86, 86, 86);letter-spacing: normal;">张文宏说：“新冠病毒会找到每一个人。当群体免疫的屏障建立起来后，新冠病毒会去寻找尚未建立起免疫屏障的人。所以第一波感染控制较好的国家，第二波感染的峰值就会比较高。”</span></p><section data-mpa-template="t"

normal;">张文宏介绍，6个月后如果再打疫苗，抗体水平就又开始变高，从而防止感染。抗体水平调高以后，免疫系统更加容易重新被唤醒，从而显著降低感染风险。此外，仍需进行抗病毒小分子药物的储备。一个很重要的举措是建立起可以在48小时内及早治疗的模式，市民可以就近到社区卫生中心测抗体或抗原，给予相应的药物。</span></p><p style="margin: 0px;white-space:
