Italian newspaper REPUBBLICA claiming the Oxford study to be shocking, because
” Coronavirus may have infected 50% of UK population”…

In the original FT article, one can read the complete analysis of the author of the research paper, Prof. Sunetra Gupta:

…fewer than one in a thousand of those infected with Covid-19 become ill enough to need hospital treatment…The vast majority develop very mild symptoms or none at all.
…I am surprised that there has been such unqualified acceptance of the Imperial model.
If the findings are confirmed by testing, then the current restrictions could be removed much sooner than ministers have indicated.
