Examine: Smartphone apps support in monitoring and reporting COVID-19


Share post:

The widespread use of assorted smartphone apps launched in the course of the COVID-19 pandemic, most notably contact-tracing purposes, will be seen as a optimistic improvement.Nevertheless, extra analysis should be executed to find out how these applied sciences will be refined for future use instances.

This was the important thing conclusion of a assessment paper printed in Nature Biotechnology, whose authors stated that, regardless of affected person privateness and knowledge safety issues, the apps had been useful to contact tracing, particular person screening and a basic understanding of outbreak epidemiology.

“Whereas there have been successes and failures in every class, outbreak epidemiology and particular person screening had been considerably enhanced by the attain of smartphone apps and accent wearables,” the report famous.

The primary benefits of smartphone-based app knowledge embody close to real-time outcomes, and the power to extrapolate knowledge from giant inhabitants teams. Purposes that had been developed to trace influenza, earlier to the pandemic, had been capable of pivot to monitoring COVID-19.

Using apps to diagnose potential COVID-19 signs may be improved sooner or later as smartphone cameras develop into extra refined. A super diagnostic app ought to combine options discovered throughout a mess of apps presently available on the market. 

“To be accessible to an underrepresented and underserved inhabitants, it ought to have the ability to combine the knowledge from any sensor, together with that from much less refined cellular units with restricted options,” the report stated.

Contact tracing, probably the most generally used COVID-19-related smartphone app operate, was cited by the paper as having probably the most critical knowledge privateness points. Authors of the report consider that future contract-tracing apps ought to contemplate not solely proximity, however native biometric, pathogen and environmental knowledge to enhance efficacy.

“The best contact-tracing app would work in actual time, protect knowledge privateness, adjust to native rules, result in actionable and measurable outcomes, be on native units to keep away from bandwidth points and, for public well being functions, not require opting in,” the report really helpful.


With greater than six billion smartphones in use worldwide, the power of cellular apps to help in data gathering and dissemination shall be essential going ahead. Smartphones are already used to collect geolocation knowledge and different varieties of knowledge accrued by customers.

Because the paper famous, nevertheless, the important thing points to be resolved deal with knowledge safety and privateness points, in addition to on the challenges of digital well being illiteracy and structural inequities.

There are additionally indicators that smartphone apps might be geared up with extra superior diagnostic performance. A smartphone-based COVID-19-detection take a look at from Australia confirmed a excessive diploma of accuracy, appropriately discovering COVID-19 in 92% of contaminated contributors of a scientific trial.

As well as, researchers discovered {that a} loop-mediated isothermal amplification-based methodology mixed with smartphone detection was capable of take a look at for COVID-19.


Using cellular apps may have extra preventive makes use of for at-risk populations throughout pandemics or seasonal well being occasions.

In August 2021, U.Okay. home-care supplier Cera launched a flu-tracking and therapy app, which makes use of synthetic intelligence and machine studying to help earlier analysis and sooner therapy of flu in older inhabitants teams.

“Continued use of apps throughout the digital infrastructure guarantees to supply an essential device for rigorous investigation of outcomes each within the ongoing outbreak and in future epidemics,” the Nature Biotechnology report famous.
