A person’s heart and breathing rates increase and heart rate variability decrease as a viral infection ramps up. All of these are measurable using a modern-day smartwatch. Researchers at Purdue University are starting a study to see if continuously collected biometric smartwatch data could be used to detect early signs of viral infections, including COVID-19.
