Diagnosing and detect coronavirus in advance has been one of the most complicated factors in preventing its worldwide spread. Aside from lack of foresight and prior knowledge, the symptoms have also not helped contain the pandemic. 

Fever, cough, throat irritation, and dyspnea are its usual features to detect coronavirus, making it easy to confuse it at first with a common flu. 


Researchers at Stanford and Scripps Research, focused on anticipating influenza and similar viruses with data collected through wearables, expand their studies to mitigate the pandemic

It is even possible that the infected do not have symptoms or are very mild. 

Hence the importance of the “test, test and test” is important to detect coronavirus, repeated by the Director General of the World Health Organization, Dr.Tedros Adhanom

To help with these tests, smart watches want to detect coronavirus even before the infected person knows it.


At Stanford University and the Scripps Research Translational Institute, they have been relating data collected by wearables, such as Fitbit, Apple Watch, Garmin and Biostrap , to viruses like the flu for years.

As Jennifer Radin, an epidemiologist in the digital medicine division at Scripps Research, explains, taking the average heart rate during a person’s sleep as a reference makes it more or less easy to detect abnormalities in this pattern

Each individual has certain values. If we control this information with smart devices and see certain alterations, we can almost foresee a flu in real time, when it is incubating”.

Earlier this year, Scripps, in collaboration with Fitbit, published the results of a two-year study on flu monitoring in The Lancet. (Click to see report

Radin and his team analyzed data from more than 47,000 American users of the device. They paid special attention to increases in resting heart rate and abnormal changes during sleep and compared them to weekly estimates of similar illnesses in the region where they live. 

As the epidemiologist highlights, the Fitbit data significantly improved the prediction models for influenza. 

“Participants learned about how much and how wearable data changes during an illness. This is essential to monitor a possible pandemic beforehand”.

Precisely, taking advantage of this knowledge and similarity with the coronavirus, he wants to do his bit in the eradication of Covid-19 . 

The new study is called Detect and is based on a mobile application designed by its Institute. The intention is to trace patterns similar to those of the previous investigation to detect rapidly spreading viral diseases.

At the moment it is only available in the United States, but the intention is to export it to the rest of the world. 

In 2017, it demonstrated that there was a direct relationship between deviation in physiological patterns and the body’s inflammatory response. Research team collected 2 billion measurements thanks to wearables .



The key is the algorithm he designed in the study three years ago , known as “Heart Change,” which is trained to identify change in certain health patterns. It is very helpful to detect coronavirus.

“Detecting changes in heart rate, body temperature and oxygen saturation is key to knowing that someone has been infected. All these parameters change even in an asymptomatic phase ”.

But, It is too early to reach such a level of precision. For now, team’s content to create a general screening tool that, for example, is capable of telling the user that their heart rate is high and they shouldn’t be going to work. Enough to reduce the spread of a virus as contagious as Covid-19 .

Behind both projects there is the limit of privacy. Without data it is impossible for these devices to have sufficient training to be an effective tool.

It is important that more and more participants join this initiative especially those who got sick, to train algorithms well. More data will give us more accuracy to detect coronavirus and opportunity to achieve some fast results.

The first wave of coronavirus expanded almost by surprise, but certain experts are already advancing that in winter there is the option that the pandemic will be more virulent. 

With their sights set on this near-immediate future, researchers are working hard to fine-tune the clocks , which are so precise as to distinguish whether the changes in patterns are due to stress or a virus. “It is still surveillance information that the health systems themselves can use to adopt some measures or others,”

Technologies and AI (Artificial Intellegence) rapidly chaninging our lifestyle. It is Possible, In near future human will evolve more powerful creature on this earth after Covid-19 crisis.
