Mummy and Daddy’s little super spreaders back to school.
Students back to University.
Young people who are fed up starting to ignore the rules.
Social distancing and hygiene becoming more and more lax in general.
People going back to offices and workplaces.
Winter approaching
An inept government in charge.
This is definitely the start of a second spike and unless they are willing to put in place some of the draconian measures of the spring, I personally doubt it can be avoided.
There cant be another national lockdown or the country will collapse and millions of jobs will go and not come back.
