You may recall my recent post describing studies that demonstrate how accurately dogs can sniff out COVID-19. The answer to “What’s Next?” may be found on your wrist right now. “Wearables” outfitted with artificial intelligence (AI) to report back health data may send a message to asymptomatic or presymptomatic people with the virus before they spread the disease. That means Fitbits, smartwatches, and heart rate monitors that cardiac patients strap to their wrists may help us fight against those dreaded spikes we’re seeing nationwide. The key is that these wristlets monitor heart rate.
