How Cambridge University Test Students For The Covids

In Tom Whipple’s excellent article in The Times today, which is entitled In Search Of A Less Painful Route Through The Long Covid Winter, there is this paragraph.

They also point to a different, smaller-scale, test. In the summer, Cambridge University decided to go its own way on testing. Each “bubble” of students put their swabs to be tested together. If they contained a positive — validated through a far more effective laboratory test — they were each retested. At the start of the autumn term, the university experienced the usual run of cases. In the final week, when other universities were seeing mass outbreaks, all 10,000 students were tested. There were zero positives.

Could this simple method, speed up mass testing of residential areas, care homes and other universities?

One-Hour Covid Test Approved For Rollout

The title of this post, is the same as that of this article in The Times.

This article is more than the title as it details four testing methods, currently being rolled out.

After reading this article, I would not be surprised to see an affordable COVID-19 testing device being developed and available for non-professional use in the coming months.

Getting it right, will bring the team so much of a financial reward, they’ll make Dyson look like pauper. No wonder organisations like Cambridge University, Imperial College, big pharmaceutical companies and hedge funds are backing development.

As these tests are often about measuring the intricate properties of both human and virus DNA, I wonder how many other collateral benefits will aid diagnosis of diseases like cancer.

Is My Local COVID-19 Testing Centre Going Walk-In?

I took these pictures as I walked past the car-park, that is used as a COVID-19 testing centre at week-ends.

It looks to me, as if, they’re going to allow people to walk-in for testing!

The Government’s Terrible COVID-19 Statistics

In an article in The Times today, Sir David Speigelhalter lambasts the Government over their collection of COVID-19 statistics.

I have been involved in the analysis of several very large databases and four factors improve the quality of the answers you get.

  1. The more records or in this case tests you have, the better. So I back David Speigelhalter! We should stop people on the street and test them!
  2. The more fields or pieces of data in each test you have, the better. So perhaps each test should be linked to your NHS record.
  3. The quality of the data is important. In my experience NHS scores about two out of five for quality as a lot of medical staff, often fill it in badly. In one case, I was looking for reasons for low birth weight babies and in many cases, the field was filled with 9.99 Kg.
  4. And then there’s the output of the data. I was taught how to display data for idiots, by the former Chief Accountant of a FTSE 500  company, who was working as the Chief Management Accountant of a Clearing Bank. He had found showing scatter diagrams with each branch as a single point on a large sheet, really got Branch Managers to think about what they are doing, if they weren’t running with the herd. These diagrams made problem branches stand out like the sorest of thumbs!

So where are the scatter diagrams for all of the Health Authorities in the UK, so everybody can see how their area, is doing against everybody else?

By the way, I trust Sir David, as we have the same birthday and share it with James Cameron, Jeff Thomson, Katherine Hamnett, Lawrence of Arabia, Menachem Begin and Madonna.

COVID-19 Testing In Dalston

As I walked to Marks and Spencer, this morning, they were setting up a COVID-19 testing site, in the car park near Dalston Junction station.

Note that when I came back, there were a lot of cars queuing to get in.

Thoughts On The COVID-19 Testing

I must first congratulate all those involved in organising and carrying-out the tests.

As someone, who has analysed many large databases for patterns of perhaps marketing information, product recalls or criminal activity, 100,000 tests per day or million in ten days, is a very large amount of hopefully reliable data, that I believe can be used to answer a lot of relevant questions about the progress of this pandemic and our very boring (For me, at least!) lockdown.

I hope, that the tests collect all the right data to go along with the physical data.

But I suspect that some important scientifically-correct questions won’t be asked. For instance.

  • What is your place of birth?
  • What is your BMI?
  • How much exercise do you do every day?
  • What is your religion?
  • How often do you attend a religious service?
  • How many in your household?
  • How many generations in your household?
  • Do you have a pet that needs exercise?
  • Do you have any drug habits?
  • Do you have any allergies?
  • Do you smoke?
  • How much alcohol do you drink?
  • Are you vegetarian?

Only by collecting a full database alongside the testing process, will we get maximum value out of the testing.
