McGill University team develops AI that can detect infection before symptoms appear

MONTRÉAL, JUL 30 – The AI platform detected nearly 90% of respiratory infections up to 72 hours before symptoms, enabling earlier medical intervention to reduce hospitalizations and healthcare costs.

  • Researchers at McGill University developed an AI platform that predicts acute systemic inflammation before symptoms appear using wearable biometric data.
  • The AI model was created because early infection detection based on symptoms or PCR testing often occurs too late for effective treatment.
  • In a study with 55 healthy adults inoculated with a weakened flu vaccine, the AI analyzed over two billion data points from smart rings, watches, and shirts.
  • The AI accurately identified almost 90% of confirmed positive cases and was able to detect signs of inflammation related to COVID-19 in four infected individuals up to three days before symptoms emerged.
  • This technology could expand the therapeutic window, enabling earlier intervention, improving personalized medicine, and potentially reducing hospitalizations and healthcare costs.

MONTREAL — An artificial intelligence platform developed by researchers at McGill University is able to accurately predict acute systemic inflammation even before the onset of symptoms, based on data provided by different ready-to-wear technologies. This could one day allow physicians to tackle the problem a few days earlier, especially in patients with already fragile health conditions and in whom a new infection could have serious consequences…
