Chat about Novel Coronavirus - 2019-nCoV - COVID-19

Reading this from the the ONS:

The provisional number of deaths registered in England and Wales in the week ending 10 April 2020 (Week 15) was 18,516; this represents an increase of 2,129 deaths registered compared with the previous week (Week 14), is 7,996 deaths more than the five-year average and is the highest weekly total since Week 1 in 2000.

... it sounds like those numbers might only be lying around in a handy weekly format starting 2000? Otherwise it'd be quite the coincidence that specifically week 1 of the year 2000 had such an unusually high mortality... Here you can get the numbers starting from 2010, I can't find any actual numbers from 2000 right now.
