This week, @scalzi let me write a guest-editorial for his blog about the themes in my new crime thriller, *Red Team Blues*; specifically, about the ways that spreadsheets embody the power and the pitfalls of #ScienceFiction at its best *and* worst:

🧵 Lots of great conversation about the latest study on the effectiveness of #ExposureNotification out of the UK. What is it actually saying and what are the implications? /1🧵

Top line result of this study: "We estimated that for every 1% increase in app users, the number of infections can be reduced by 0.8% (from modelling) or 2.3% (from statistical analysis)." via @turinginst

What are the goals of #ExposureNotification apps? They alert you if you've been nearby someone who tested positive for #COVID19, prompting you to get tested and self-quarantine. That breaks chains of transmission. /3
Apropos of @thesundaytimes article, a few thoughts: firstly, as I tweeted 2 days ago 👇 & in stark contrast to the #transparency around other tech/data intitiatives - *cough* @NHSEngland #DataStore *cough* - the team published a blog on what it was doing:
healthtech.blog.gov.uk/2020/10/29/how…
healthtech.blog.gov.uk/2020/10/29/how…
In this blog, the app team gave an explanation of the latest changes it had made - including a reduction in the #RiskThreshold, which took account of TWO factors: the inclusion of a measure of #infectiousness in the API *and* a new #distance algorithm...

In case folks aren't aware, @Google & @Apple's #ExposureNotification API is quite frequently updated. As the #Android developer pages (and #nhsxCOVID18app's blog) say, the #infectiousness field was only added at v1.6; with functionality changing at 1.7 👇

For more technical background, see github.com/nhsx/covid19-a… for, e.g. system architecture (v3) and (predominantly @AWS) infrastructure.
Of course, we're still waiting for the results of the trials...

...and, as the BBC's write-up concludes, evidence that #ExposureNotification works in practice is "scant" - in ALL countries attempting it, not just the UK:

Efficacy (as in NZ) will most likely come from #QRcheckin, which could've been done months ago.

Bottom line, will I be downloading it? Already have - as I did with the other versions, to see what they did.
Will I be using it? Probably. Not least to avoid having to hand over personal details; combined with regular data deletes/resets.
Will I trust it to keep me safe? No...

"Routine public health surveillance data suggest that notified contacts [from an #ExposureNotification app] seek SARS-CoV-2 testing."
Early findings from 🇨🇭Switzerland on the efficacy of their app. /1

Tl;Dr: "In conclusion, based on the data collected during the initial deployment of the SwissCovid app, we argue that voluntary digital contact tracing can show similar effectiveness at identifying infected partners of index cases as classic contact tracing." 🙌 /2
There's good observations in here that it's about the entire ecosystem - they had some challenges due to authentication codes not being sent out rapidly and how interoperability is critically important. 🔍 /3
