visibility: visible;">5月8日国家联防联控机制发布会称全国发热门诊监测结果显示“五一”期间部分地区疫情出现小幅上升。国家卫健委组织专家研判，认为由于人群接种疫苗和新冠病毒感染后的免疫力存在随时间衰减的客观规律，全国疫情近期开始又出现缓慢上升的情况，这种变化趋势符合预期，也与全球奥密克戎病毒株波动流行的规律相似，短期内出现大规模疫情或大幅回升的可能性比较低。</span></p><p style="margin-top: 25px;

box-sizing: border-box !important; overflow-wrap: break-word !important; font-size: 16px;">监测数据显示，截至5月中旬，XBB系列变异株已成为我国新冠病毒的主要流行株，境外输入病例中占比达95.6%，和全球情况基本一致。陕西省近期监测数据也提示XBB系列变异株已成为我省绝对优势流行株。从我国和全球监测数据来看，XBB系列变异株其传播力和免疫逃逸能力均强于早期流行的奥密克戎变异株，但其致病力没有明显变化。</span></p><p style="margin-top: 25px;

box-sizing: border-box !important; overflow-wrap: break-word !important; font-size: 16px;">研究发现，新冠病毒感染后产生的抗体在早期能起到保护人体的作用，但随着时间的推移，对于已经“阳过”的人群或者接种新冠疫苗获得免疫的人群来说，体内的新冠病毒抗体水平在感染或接种疫苗4-6个月后逐渐衰减，免疫保护力下降，不足以对抗病毒来袭，从而发生二次感染。</span></p><p style="margin-top: 25px;

box-sizing: border-box !important; overflow-wrap: break-word !important; font-size: 16px;">无论是首次感染还是二次感染，奥密克戎变异株的临床表现一般集中在上呼吸道，大多数人对症处理即可。临床观察发现“二阳”比“首阳”症状普遍更轻，主要表现为发热、喉咙痛等上呼吸道症状。但对于脆弱人群如高龄老人、有严重基础疾病的重症高风险人群，一旦发生感染，及时及早就医。</span></p><p style="margin-top: 25px;

box-sizing: border-box !important; overflow-wrap: break-word !important; font-size: 16px;">保持良好卫生习惯 坚持做好个人防护可以一定程度减少新冠病毒的感染概率，不管是否“阳过”，可根据实际需要科学佩戴口罩；此外还要做到勤洗手，保持室内环境卫生，多通风、常消毒；保持社交距离，加强锻炼，合理饮食，提高自身免疫力。对于重点人群、脆弱人群如老年人、有基础疾病的人群更要加强防护。还应加强自我健康监测，若确定感染了新冠病毒，应避免带病工作、上学，如有高烧不退，呕吐、腹泻等症状，要及时就医和服药。</span></p><p style="margin-top: 25px;
