absolutely this.
The story is more about just how bad seemingly quite a lot of journalism be that local or national has become.

Looking at Sunderland over the last six weeks ending each Sunday
w/e 14/6 9 cases; 3.2 per 1000,000 population; in the same week the North East overall was around 8.9 cases per 100,000 and England overall 11.5 cases per 100,000; then
w/e 21/6 5 cases; 1.8 per 1000,000 vs region 4.8 and England 10.1
w/e 28/6 5 cases
w/e 5/7 2 cases; 0.7 per 100,000 vs region 2.2 and England 6.8
w/e 12/7 7 cases 2.5 per 100,000 vs region 2.7 and England 6.6
w/e 19/7 8 cases 2.9 per 100,000 vs region 2.6 and England 6.9
So mathematically yes the number of cases in the last two weeks at 15 is double that of the two weeks prior to that; but the overall case ratio per 100,000 people in still low.
