A non-invasive biometric sensor screening device accurately identified flu and the common cold prior to symptom onset, researchers found in two small human challenge studies.
In the first, which involved 31 participants inoculated with influenza, Empatica’s E4 wristband detected the difference between infection and non-infection with up to 92% accuracy. The second involved 18 participants inoculated with human rhinovirus, and here the E4 wristband detected the difference between infection and non-infection with 88% accuracy, reported Jessilyn Dunn, PhD, of Duke University in Durham, North Carolina, and colleagues.

In fact, early in the pandemic, a group of prominent researchers dismissed lab-origin notions as “conspiracy theories” in a letter in The Lancet. A report from a World Health Organization (WHO) “joint mission,” which sent a scientific team to China in January to explore possible origins with Chinese colleagues, described a lab accident as “extremely unlikely.”
