英国疫情怎么了

先看看英国官方发布的数据。到8月下旬，英国居民中约93%有了新冠抗体。有些来自自然感染，更多的来自疫苗。

An estimated 93.6% of the adult population in England, 91.2% in Wales, 91.9% in Northern Ireland and 93.3% in Scotland tested positive for COVID-19 antibodies in the week beginning 23 August 2021. The presence of antibodies suggests a person previously had COVID-19 or has been vaccinated.

按照一年多前的说法，当居民中有70%以上有抗体时，即可达到群免，能够控制疫情了。

可事实证明，快速增殖传播的delta变种，打破了群免的幻想。

 

下图显示，自八月以来，每日新冠病例数一直在增加。

 

值得一提的是，病死率远远低于前几波。

如果有了新药、或新疗法，病死率进一步降低，大家也许不在乎啥“阳性”了。

 

 

美国的数据也类似

CDC Finds Over 83 Percent of Americans Had COVID Antibodies Before Delta Surge

别指望群免啦，靠免疫别人来保护自己。

还得靠自己打疫苗，减少染病后的病死率。因为有充分数据证明：没打疫苗的，病死率比打了的高11.3倍。

 

重点：加强个人防护，有病及时就医。
