What ever happened to using AI to diagnose infections based on cough sounds? It seemed like a promising approach.

By the time you experience symptoms you've already been contagious for a few days. It's like trying to detect fires by looking for piles of ash.

Did you even read the article? It's about detecting cases without clinical symptoms yet.

I vaguely remember reading more about this elsewhere and I believe they only used COVID positive patients. It would be interesting if there are follow-up studies with mixed training data if true.

No the researchers tested using both positive and negative patients.

Ah, ok. I think this was the article I originally read which implies they only used 2,500 covid positive patients. But rereading it, maybe it’s just unclear reporting.

“Across around 2,500 captured cough recordings of people confirmed to have COVID-19, the AI correctly identified 97.1 percent of them – and 100 percent of the asymptomatic cases.”
