It detected 97% of COVID cases in a sample of 2,500 people who *all* had COVID. No mention of the rate of false positivity. Until proven otherwise, this is just an AI that says almost everyone is sick.

That article doesn't talk about it at all, but the paper it comes from actually does given both the sensitivity and specificity of the method right on the front page. 98.5% sensitive and 94.2% specific in case anyone's interested. I'm not sure why the author of the article decided to focus in on the 97.1% accuracy, when the overall accuracy for both covid positive and covid negative on a database of 5320 subjects was 98.8%!

Thanks. What a shitty article.

Yeah but science alert doesn't ever go for quality, they go for getting the info out there to people who wouldn't otherwise have heard it. I think that's generally a good thing ¯\_(ツ)_/¯

Somebody is looking for an Angel to rip-off.

It detects the symptoms in people who don't have any symptoms? What a wonderful test!
