The epidemiological impact of the NHS COVID-19 app

Looking back at the NHS app data from Sept-Dec 2020, it shows that for each life that may have been saved, there were 100 years of house arrest. Let me take you through the data. https://t.co/0SBHhuwIXc

@Avustaja Millä tavalla liikaa? Ei kai kukaan voinut ennakoida terveydenhuollon suhtautuvan pandemiantorjuntaan vihamielisesti ja territoriaalisesti. Esim. UK:ssa vastaavan sovelluksen tutkittiin säästäneen n. 4200-8700 ihmishenkeä. https://t.co/euHmfYB

@dr_michaelmarks @TheLancetPH Hard to square with UK NHS app Nature paper. I tend to believe the Aussies, in this case. Based on the nature of covid spread (peri-symptomatic period) rather than quality of the papers. https://t.co/o4ymkIhtx5

Remember exposure notification apps? There's good data they're helping. Far from perfect, but they are reducing harm at almost zero privacy cost. Omicron's shorter incubation will likely reduce utility. We should speed up activation of notifications. h

A paper out of Nature estimates that the UK's anonymous app (GAEN) achieved approximately 28% adoption in the total population and "averted ~600,000 infections - about 20% of what the total would otherwise have been - and saved thousands of lives." https:/

Das ist Alles schön und gut, aber es löst nicht das Problem der CWA. Meine Kritik an der CWA setzt an ihrer Zielsetzung an. Statistische Spielereien sind unter diesem Ansatz irrelevant. Nach Spahn ist die Zeit des Schönredens vorbei.

I don’t think we know the full scale of this wave tbh. We have hints from the ONS studies, but anecdotally, it feels like a lot of people have stopped testing properly. Time for another proper government information campaign.

Change your stupid messaging! In particular get people to test, test and test again. We know that LFTs are great screening devices, and we know that test and trace prevented 300k-600k cases last winter. 4/4 /END https://t.co/7AAF0SQrmj

The UK has demonstrated that Exposure Notifications saved lives. Similar elsewhere. Australia is in an even better position to benefit from an app like this due to the (relatively) low case rate. Even if the benefit is small, _every bit counts_. https://t.
