COVID-19 Cases in Ireland – Updated Daily

I thought I would make a record (for posterity, if there ever is such a thing) of the evolution of the number of confirmed cases of Covid-19 (Coronavirus) in Ireland after the first case on 29th February; 12th March 2020 was when Schools and Colleges in the Republic were closed). I will update the data on this page after the daily briefing by the HSE, and update the plot whenever I get the time.

There have been changes in testing frequency and strategy over this time so one can’t use these numbers reliably to track the growth of the epidemic. Each number should really be treated as just a lower limit on the actual number of cases. It is worth stating also that the “daily” cases are those reported on a given day not those that necessarily happened on that day: there can be a lag, for example, between a death occurring and it being reported officially. I’ve resisted the temptation to fit a model because the changes in testing and reporting are difficult to incorporate. Because (a) the data are quite noisy and (b) there is a likely “weekend effect” in reporting, I’ve decided to present the results from now on as 7-day moving averages.

This makes it very clear that the curve showing daily new cases first flattened a bit but then rose again quite sharply and now seems to be falling once more. On a linear y-axis the cases look like this:

 

 

 

The numbers for deaths on a linear scale look like this:

You will find discrepancies on several days between the cumulative totals (for both cases and deaths) and the result of adding the daily increment to the previous day’s total. This is because of the `denotification’ of old cases. For example, there is a discrepancy of 7 between the total cases recorded on 5th June and the previous day’s total; on 5th June the Department of Health explained that this was due to 7 cases having been ‘denotified’. This also happens when deaths previous attributed to Covid-19 are no longer regarded as such. Some websites are deducting denotifications from the daily reported figure, but since these might refer to much older cases I think it’s more instructive to keep the daily figure as that reported but adjust the running total by the number of denotifications.

Other notes:

*The figures for 10th April to 19th April include a backlog of results returned from labs in Germany which should be attributed to earlier dates; some of the samples were taken up to two weeks earlier. The actual figures returned from testing in Ireland were: April 10th – 480; April 11th – 553; April 12th – 430; April 13th – 527; April 14th – 548; April 15th – 657. April 16th – 629; April 17th – 597; April 18th – 630; April 19th – 445.

#The new cases figure for 14th May includes 223 historical cases notified late. These are included in the overall total but not in the daily figure. The total reported on this day was 426.

^The total deaths figure for 24th April includes 185 ‘probables’ that lack laboratory confirmation. I have included these in the total but not in the daily figure.

~The figure of 46 new cases on June 13th includes 22 cases that arise from tests performed on 8th & 9th June and would normally have been reported on 10th & 11th June.&Nine deaths were reported on 23rd July, but 8 of these were late reports of deaths from April, May and June. I have increased the cumulative total by 9 but as only one is new that is the figure quoted in the list.~Five deaths were reported on 6th August but 4 of these were late reports of deaths from April and June. I have increased the cumulative total by 4 but as only one is new that is the figure listed.
