Can health bracelets find new coronal viruses?Is this reliable?

The health tracker worn on the wrist may be found in the first few days before the symptoms appear.

The Guardian reports that more and more people around the world use these devices to monitor changes in skin temperature, heart and respiratory frequency. A new study shows that even before the first obvious signs of the disease appear, these data can be combined with artificial intelligence (AI) to diagnose new crown pneumonia.

The researchers concluded: "Wearable sensor technology can detect the new crown epidemic before symptoms." The research results were published in the BMJ Open magazine.

This discovery may cause health trackers to adapt to artificial intelligence in order to detect the new crown virus as early as possible, and only need to find basic physiological changes.

This can help users provide their early warning system that may be infected, which in turn can help prevent diseases from spreading widespread.

In this study, from the beginning of the big popularity to April 2021, the 1163 people under the age of 51 were tracked. They were asked to wear the AVA bracelet at night, and the device saved data every 10 seconds. People must sleep at least four hours to work.

Synchronization of bracelets and smartphone applications, people will record any activities that may affect the results, such as alcohol, prescription drugs and pastime. They also recorded possible COVID-19 symptoms, such as fever.

All participating people regularly conduct new coronary virus fast antibodies, and those with symptoms also undergone the PCR swab test. A total of 1.5 million hours of physiological data was recorded, and the new crown infection was confirmed among 127 people, of which 66 (52%) were wearing their equipment for at least 29 consecutive days and were included in analysis.

Studies have found that the body has changed significantly during the incubation period of infection, the period before the symptoms, the occurrence of the symptoms, and the recovery period during the occurrence of the symptoms.

Overall, the dual combination of health trackers and computer algorithms correctly identified 68% of new coronary virus positive patients two days before the symptoms appeared.

The team pointed out that the research has limitations and is not captured by all COVID cases.

Therefore, the health bracelet can find the new coronary virus, which is not very reliable at present.
