Data science and COVID-19

Hopefully you can tap the brakes on your enthusiasm over antibody testing. Some of the tests have false positive rates as high as 16%, and CDC and AMA caution against using antibody test results to make decisions.

physicians and the general public should not use antibody testing to consider anyone immune to the diseaseā€”doing so may lead individuals to falsely assume they can stop physical distancing and further the spread of illness,ā€

IMHO, this is mostly a map of counties where COVID was not present in non-trivial amounts prior to the effects of sheltering in place (in green) vs places where it had already made inroads (not it green).

The rate of transmission dropped precipitously once shelter in place started. Thus, places where it had not yet established a foothold were less much affected (which is a Good Thingā„¢).

What remains to be seen is whether those trends will hold once people stop socially isolating, esp. if they fail to take even simple precautions.

Next 2-3 weeks should be interesting.

If the hospitals are still functional in 3 weeks, we may be in good shape.

If theyā€™re swamped because of last weekend, we have problems.

If you meant to reply to me then I think youā€™ve misunderstood the data science. That is the topic here. I agree that the tests should not be used to decide ā€œindividualā€ risk. For instance, we donā€™t want an ICU nurse, like my daughter, to throw caution to the wind just because an antibody test came back positive. That is the CDC and AMA warning. All tests have an error rate but meaningful stats can still be obtained so long as the errors are not systematic. However the data for the article I linked is using large scale statistics, where random errors have an averaging affect, to estimate the total number of positive patients. That is very different use than what you are implying by the articles you linked.

Some interesting information about the tests and the error rates for the tests in this video.

The rest of the series by the same channel is very good as well. ( Not a doctor myself. Useful explanations for meā€¦ )

To heck with it with you experts. Whose ā€œscienceā€ are we supposed to follow anyway?

They are all guessing and blowing it out of their anusiā€¦

I work in healthcare fraud analytics. Before that I worked in medical research, including analyzing stats for clinical drug trials. That said, I can assure you I donā€™t understand what some of the ā€œdata scientistsā€ are doing.

It makes more sense now, since apparently data science means taking test results with false-positive rates far too poopy (the technical term our principal investigator used) for peer-reviewed publication and aggregate lots of those and use it to make policy. That explains a lot about some of the ā€œartificial intelligenceā€ platforms being peddled to analytics folks.

An important post. So far Iā€™ve seen somewhere between 10-15 serology tests, mostly from labcorp, all of which have been negative. What does this mean? Absolutely nothing, of course, but it is interesting none the less.
