据《环球网》报道,“新冠肺炎不同于SARS,在前5天后5天无症状但有明显传染性。

31日,据《中国侨网》报道,“助力基层疫情防控万里行”活动在广州启动,中国工程院院士钟南山现场解答春节期间基层疫情防控的相关问题。

当前国内外疫情形势如何?

钟南山表示,目前国内局部出现了疫情蔓延的情况,国际疫情形势仍然居高不下,而且冬季在客观上也不利于疫情防控。

从近期国内出现的感染情况看,黑龙江、吉林、河北等地出现的感染案例主要在基层,基层群众和医务人员的疫情知识普及力度相对比较薄弱,检测能力也比较薄弱。“为什么局部出现了集聚性的感染,说明我们在一定程度上放松了警惕,要好好总结。”

中国的疫情防控还面临哪些挑战?

钟南山指出,当前中国的疫情防控遇到了一些挑战。首先是病例散发,主要在农村传播。此外,还遇到了一些病毒变种,科研人员最近对疫苗效果也进行了深入研究。随着确诊病例不断减少,疫情防控形势逐步好转,一些地方在一定程度上放松了警惕。目前,有些地方出现了散发性和局部性的疫情传播,值得警惕。

注射了新冠疫苗还用戴口罩吗?

钟南山表示,注射了新冠疫苗后,还要继续佩戴口罩。中国的疫苗主要是全病毒灭活疫苗,安全性很好。一般情况下,注射完第一剂后便会出现抗体,保护水平大约为60%至70%;第二剂注射完14天后,保护水平能达到近90%。

疫苗打完约两至三周后才有抗体,在注射疫苗和产生抗体的间隙,仍有感染风险,要注意个人防护。

核酸检测转阳病例有很强的传染性吗?

钟南山认为,转阳病例并不具有很强的传染性,这些病例可能还会有核酸片段的残余。但有核酸片段的残余不等于有活病毒,很少看到核酸转阳病例还会传染别人。

如何做好农村的疫情防控?

钟南山表示,现在农村是疫情防控的重点。从最近发病的情况来看,60%至70%的病例都在农村。做好防控需聚焦三个关键词:科普、培训、检测。

据《环球网》报道,“新冠肺炎不同于SARS,在前5天后5天无症状但有明显传染性。”钟南山院士今天表示,这是新冠肺炎研究的最新发现。

春节临近,高风险区就地过年,中风险区原则上就地过年,低风险区倡导就地过年,特别是在农村少点串门和聚会,要重点监测。

农村的科普一定要做到位,如果出现非常明显的疲劳、嗓子疼、发烧,一定要做核酸检测。

村民集合坐大巴去县城检测会造成相互感染,这种情况不应该再出现,现在检测车混检一天最高做50万,开到村头不要让老百姓来回奔波。
