世界卫生组织宣布结束新冠疫情紧急状态

世界卫生组织宣布结束三年的新冠疫情紧急状态。

新冠疫情造成了全球确诊新冠死亡七百万人，全球超额死亡人数约两千万人，经济损失万亿美元数量级。

这个是公共卫生系统的灾难性战略失败。

如果各国政府放任自流什么都不做，新冠疫情在大约两个月结束，全球超额死亡人数约两百万而不是现在的两千万，经济损失也要减少100倍。非洲比较接近放任自流，死亡和经济损失较少。

如果采用我的反向隔离战略效果更好。放任自流是自发的反向隔离。反向隔离就是正常健康人群自然感染新冠病毒，而有基础病的高危人群自愿居家隔离。

压平曲线是最差的战略。这是我2020年四月就预测过的，没有人相信。

世界卫生组织还没有醒悟过来。总干事谭德赛说，最坏的情况就是一个国家以新冠疫情紧急状态结束为借口而取消疫情防控措施。其实，真相恰恰相反，最好的情况就是取消之前的错误的防控措施。

即使只有少数人继续压平曲线的战略，新冠病毒可以持续低强度地在人群中传播和变异，最终变异到原来的免疫失效，新冠疫情卷土重来。勿谓言之不预。

谭德赛原话如下：

"Yesterday, the Emergency Committee met for the 15th time and recommended to me that I declare an end to the public health emergency of international concern. I've accepted that advice. It is therefore with great hope that I declare Covid-19 over as a global health emergency," Dr Tedros said.

He added that the decision had been considered carefully for some time and made on the basis of careful analysis of data.

But he warned the removal of the highest level of alert did not mean the danger was over and said the emergency status could be reinstated if the situation changed.

"The worst thing any country can do now is to use this news as a reason to let down its guard, to dismantle the systems it has built, or to send the message to its people that Covid-19 is nothing to worry about," he said.
