Coronavirus in Ireland – the Latest!

Posted in mathematics on March 28, 2020 by telescoper

Just a quick post to point out that I’ve set up a page on which I’m tracking the number of cases of Covid-19 in the Republic of Ireland.

I intend to keep the data on that page up to date as information is announced by the HSE and won’t do lots of updates as posts. I thought I’d show the latest figures here though.

The second (log-linear) plot is perhaps more informative. It shows some evidence of a flattening compared to an exponential curve. The plot in green is an exponential with a time constant of 3.5 days; it’s not a fit to the data, it’s just there to show what exponential growth would look like on such a plot (ie a straight line).

Among the additional measures introduced last night to combat the spread of Coronavirus in Ireland was the cancellation of all non-essential medical appointments.

Looking at my diary I realise that I was due to have a checkup on my knees next Friday. That won’t be happening now I suppose.

It’s about three months since I had steroid injections in both knees to halt the arthritis therein. The jabs were quite painful but worked very well and I have been able to dispense with the use of a walking stick since I had them.

The effect of these injections only lasts a few months so I was due an inspection to see if I might further ones in the near future. I think I’m doing OK, however, and I’m sure the hospitals have more important things to be dealing with right now, so I don’t mind the deferral at all.

Although I haven’t really needed my walking stick recently I think I might start carrying it again on the rare occasions I go out during the ‘lockdown’ – so I can hit people with it if they get closer than 2m from me.
