Another perspective on Coronavirus – Prof. Michael Levitt

Owing to the serendipity of a contemporary and friend of mine at King’s College London, Andrew Ennis, wishing one of HIS contemporaries in Physics, Michael Levitt, a happy birthday on 9th May, and mentioning me and my Coronavirus modelling attempts in passing, I am benefiting from another perspective on Coronavirus from Michael Levitt.

Cambridge Conversations May 14th 2020 – reading data and the place of modelling

Cambridge Conversations May 14th 2020, the second Cambridge Conversations webinar on Covid-19, featuring Professor Sir David Spiegelhalter of Churchill College, and Professor Mike Hulme, Professor of Human Geography and Fellow of Pembroke College.

Re-modelling after changes to UK Coronavirus data collection and reporting

The UK Government yesterday changed the reporting basis for Cononavirus numbers, retrospectively (since 6th March 2020) adding in deaths in the Care Home and and other settings, and also modifying the “Active Cases” to match, and so I have adjusted my model to match.

Cambridge Conversations and model refinement

In my post a few days ago at, I mentioned that the webinar I reported there was to be released on YouTube this week, and it is now available. It is VERY much worth 40 minutes of your time to take a look. It’s at

UK Coronavirus Modelling – match to data

Even having explored Prof. Alex Visscher’s published MatLab code for a week or two now, with UK data, even I am surprised at how well the model is matching up to published UK data so far (on April 18th 2020). I have reported my previous work a couple of times, once relating to the modellingContinue reading “UK Coronavirus Modelling – match to data”

Cambridge conversations 17th April 2020 – exit strategy?

As an alumnus, I had the opportunity today (with 2000 other people in over 60 countries) to attend a Cambridge University webinar on the current pandemic crisis. It was moderated by Chris Smith, a consultant medical virologist and lecturer at Cambridge (and a presenter on where more about this event will be found). TheContinue reading “Cambridge conversations 17th April 2020 – exit strategy?”

Making a little progress with a Covid-19 model and real data

In my research on appropriate (available and feasible (for me)) modelling tools for epidemics, I discovered this paper by Prof. Alex de Visscher (to be called Alex hereafter). He has been incredibly helpful. Thanks to Alex including the MatLab code (a maths package I have used before) in the paper, and also a detailedContinue reading “Making a little progress with a Covid-19 model and real data”

The SIR model and importance of the R0 Reproductive Number

In the recent daily UK Government presentations, the R0 Reproductive Number has been mentioned a few times, and with good reason. Its value is as a commonly accepted measure of the propensity of an infectious disease outbreak to become an epidemic. It turns out to be a relatively simple number to define, although working backContinue reading “The SIR model and importance of the R0 Reproductive Number”
