This is what emerges from a study by the Imperial College commissioned by the government. Between June 3 and June 7, infections increased by 50%, coinciding with the increase in cases of the Delta variant. Most of the infections were recorded among children between 5 and 12 years and young people between 18 and 24 years (in these age groups, there are five times the infections that over 65 years) .Covid cases double every 11 days .
