“疫情比想象中更狡猾!”世衛組織發出警告,更危險的還在後面 – 有海水的地方就有中國人

“疫情比想象中更狡猾!”世衛組織發出警告,更危險的還在後面

“疫情比想象中更狡猾!”世衛組織發出警告,更危險的還在後面
2,073

据中国网报道,世卫组织向全球发出警告,新冠病毒变异毒株德尔塔有可能会再次席卷全球,造成第二波全球大规模疫情。德尔塔病毒最早在印度发现,也是印度本次疫情大爆发的罪魁祸首。它曾导致印度单日新增确诊病例达到40万例,直接惊呆世界各国。

那么,为何新冠病毒会变异呢?首先,病毒进入人体后,被免疫细胞所识别,然后传递信息,免疫细胞分泌抗体来对付病毒。在免疫细胞与病毒斗争的过程中也是双方强化的过程。还有一种情况是,病毒不进入人体,在自然界中为了生存适应周边环境产生变异。比如一开始在武汉爆发的疫情,那时候的病毒专家研究发现它不能忍受高温,气温升高它就会死亡。但是,现在的几种变异病毒均能在印度、东南亚等国自由传播。说明温度对它已经构不成太大的威胁了。

可怕!新冠病毒变异后更强!

尽管目前许多国家的疫苗接种工作正在有条不紊地开展,但是全球每日新增感染人数仍维持在50万大关。英美两国更是出现了疫苗大规模被接种但是感染人数不降反升的局面。

可能考虑到便捷性和通用性,世卫组织给新冠病毒的变种用希腊字母来命名。英国的Alpha、南非的Beta、巴西的Gamma、印度的Delta和Kappa、秘鲁的Lambda,还有最新出现的美国Epsilon。其中印度出现的德尔塔传播性、毒性最强,也是本次印度疫情失控和全球第二波疫情大爆发的元凶。该变异毒株已经在全球110多个国家和地区出现。

值得注意的是,最早在武汉检测出来的新冠病毒耐热性很差,气温一高就会导致死亡。而目前变异的毒株德尔塔好像更偏爱高温天气,东南亚各国也因此成为当前疫情的“新震中”。印度尼西亚已经赶超印度,成为亚洲疫情最严重的国家。

世卫组织也表示,即使是疫苗接种率高、公共卫生体系完善的发达国家,在复工复产复学方面仍面临较大压力。更不用谈那些卫生基础差的欠发达国家,他们能获得的疫苗数量都很有限。大部分国民仍然暴露在新冠病毒的风险之中。

新冠疫情仍是世界关注的突发公共卫生事件

由于疫情蔓延没有稍缓的趋势,世卫组织正在开展病毒全球溯源第二阶段工作。

近日,世卫组织总干事谭德塞重申,新冠疫情并没有结束,疫情比想象中更狡猾,所以仍是世界关注的突发公共卫生事件。世卫组织对新冠疫情的不降级是希望各国继续绷紧神经,团结起来、互帮互助、共同抗疫。世卫组织认为,病毒产生变异、全球疫苗分配不均以及社会流动性增加是全球疫情得不到控制的三大因素。加上病毒不断的适应新环境,更危险的恐怕还在后面。

突发事件委员会对疫情防控也提出了相关意见,首先各国应继续采取相关防疫措施以阻断病毒传播,尽量缩小全球“疫苗鸿沟”,加快建立疫苗认证、病毒检测等体系以便于国际间人员流动。此外,还应该继续加强对新冠病毒变异的监测以及全球溯源工作。

新冠疫情使全球近2300万儿童错过基础疫苗的接种

联合国儿童基金会在最新的报告中指出:受新冠疫情的影响,儿童常规免疫工作受到阻碍。百白破三联疫苗作为儿童疫苗接种率的关键指标,其接种率从2019年的86%下降到2020年的83%,这中间意味着有2270万名儿童错过接种该疫苗。此外,水痘、风疹、麻疹等可预防疾病的风险也在不断增加。甚至又出现了大批任何疫苗都没有接种的儿童,这种“零剂量”儿童应该引起社会的广泛关注。

世卫组织预测疫情有望在明年得到控制

根据不完全统计,全球累计确诊病例超1.9亿,累计死亡病例超410万。数据令人触目惊心,在短短不到两年的时间内,居然有这么多人感染病毒并致死。世卫组织预测:如果我们足够幸运,疫情有望在明年得到有效控制。我相信这种预测不是空穴来风,一定是专家们经过多次研究和调研才得出的。

“疫情比想象中更狡猾!”世卫组织发出警告,更危险的还在后面

疫情的走向无人可以预测,说不定明天在地球的某个角落又会出现新的变种病毒。也说不定,一觉醒来,病毒全部消失,人们又恢复到往常的工作中去。再也不用带着口罩与人沟通交往,再也不用保持一米以上的社交距离。当然,我们的希望是疫情朝着好的方向发展。作家刘瑜在给女儿小布谷的信中有这样一句话:“愿你有好运气,如果没有,愿你在不幸中学会慈悲。”疫情这样的黑天鹅事件,被我们这个时代的人碰上可以说是件不幸运的事,但是只要我们团结互助,相信不远的将来,一定会守得云开见月明!
