Wearables could possibly detect flu even earlier than a affected person begins to indicate signs, in response to a brand new research in JAMA.
The research, performed by researchers at Duke University, confirmed {that a} wristband with biometric sensors might detect an influenza an infection (H1N1). For the research, the workforce employed the Empatica E4 wristband, a medical-grade wearable system that measures coronary heart charge, pores and skin temperature, electrodermal exercise and motion in actual time.

“Approximately 9% of the world is infected with influenza annually, resulting in 3 million to 5 million severe cases and 300 000 to 500 000 deaths per year. Adults are infected with approximately 4 to 6 common colds per year, and children are infected with approximately 6 to 8 common colds per year, with more than half of infections caused by human rhinoviruses (RVs),” the researchers wrote. “Given the highly infectious nature of respiratory viruses and their variable incubation periods, infections are often transmitted unwittingly in a manner that results in community spread, especially as no presymptomatic screening methods currently exist to identify respiratory viral diseases. With the increasing emergence of novel viruses, such as SARS-CoV-2, it is critical to quickly identify and isolate contagious carriers of a virus, including presymptomatic and asymptomatic individuals, at the population level to minimize viral spread and associated severe health outcomes.”
In this research, the researchers recorded biometric information from younger individuals earlier than and after they have been inoculated with H1N1 influenza and human rhinovirus.
In the primary research, which concerned 31 members inoculated with influenza, Empatica’s E4 wristband detected the distinction between an infection and non-infection with as much as 92% accuracy. The second part concerned 18 members inoculated with human rhinovirus, and right here the E4 wristband detected the distinction between an infection and non-infection with 88% accuracy, reported principal investigator Jessilyn Dunn, PhD, of Duke University in Durham, North Carolina, and colleagues.
“This cohort study suggests that the use of a noninvasive, wrist-worn wearable device to predict an individual’s response to viral exposure prior to symptoms is feasible,” authors of the research wrote. “Harnessing this technology would support early interventions to limit presymptomatic spread of viral respiratory infections, which is timely in the era of COVID-19.”

“We hope to learn what sickness with COVID-19 looks like at the physiological level, and how parameters around heart rate, sleep and movement change when a person gets infected,” explains Dunn. “We are also interested in comparing data from unvaccinated individuals, as well as people who develop breakthrough infections.”
