A New Zealand-based AI company has created a personal early warning indicator for COVID-19, overcoming viral spread by asymptomatic people who do not know they are infectious. By developing personal baselines of biometric data from smartphones and other wearables (such as Fitbit, Apple Watch and Samsung), the indicator detects changes to those individual baselines that fit COVID-19 patterns – changes that occur as the body begins fighting viral infection up to three days before people know they have the virus.
