14,030 new #covid19uk positive tests reported today (28-Apr).

Overall England is DOWN 41% on previous Wednesday and day-1 lateral flow positives are also down by 41%.

England has now been showing consistent week-on-week drops since the 25th of March (34 days ago).

Chart to show England positive tests (as of 28-Apr) by breakdown of first infection events and possible reinfection events.

Possible reinfections were added to the data from 31-Jan and the rolling average vs. total tests is currently about 14%.

Longer term view. 14,030 new #covid19uk positive tests reported today (28-Apr). This brings the rolling average by specimen date (allowing 4 days for lag) to 19,922, equivalent to around 26-Jun (i.e. 299 days ago), a reduction of 8860 (31%) in the last week.

Closer look at the latest 45 days, with today's added numbers highlighted in yellow. Individual nations and animated England charts further down the thread.

Separate charts for England (10945) Scotland (2587) Wales (143) and Northern Ireland (355). Note the different scales. Also on certain days the specimen-date data for Scotland/Wales/NI doesn't get updated so the yellow bars may be mising or include multiple day's numbers.

Animated chart to show how the #covid19uk positive tests by specimen date have been contributed to by reports over the last 7 days. Note this just includes England numbers as other nations don't always publish their specimen date numbers every day.
