"I doubt there is any clear cause of cases rising though tbh"
That's rather pessimistic
Track and trace in Germany found returning holidaymakers were a significant cause
The usual case from workplaces, family parties, places of worship etc continued at about the same level
However, cases have been falling in Germany for about the last 10 days, as those arising from holidaymakers have been tracked, traced & isolated
Uk holidays seem 2-3 weeks behind Germany, so hopefully the Uk will see the same downward trend,
as the returning vacationers work their way through the system
In the Uk and Germany, cases have - SO FAR - remained low enough for this downturn to happen fairly soon,
whereas in France & Spain the cases spread much further and will take longer to get back under control
