Researchers at the Stanford University School of Medicine have recently developed an app designed for a smartwatch that can alert users whenever their body shows signs of getting an infection.
The smartwatch app uses an algorithm that can detect any changes in the resting heart rate and step count of an individual. The app was able to correctly identify signs of COVID-19 even before the symptoms arose, 63 percent of the time.
The alerts from the app do not tell when a person is already ill. It alerts that the body is going through certain changes that might lead to illness. In other words, it is another form of prevention.
Certain medications might make it a bit difficult for the algorithm to detect a stable resting heart rate.
Other factors possibly causing hindrance are menstrual cycles, extended air travel, and more time in a high-altitude region. Researchers are working on them, and are hopefully going to overcome them.
The app will initially be available on Fitbit devices and later, will be introduced to other smartwatches and devices capable of tracking heart rate.
