Your smartphone screen may tell if you have contracted Covid-19

With Covid-19 testing being one of the most important measures for preventing the virus’s transmission, new technology can aid in identifying the novel coronavirus utilizing samples acquired from smartphone displays.

For middle- and low-income countries, the non-invasive and low-cost Phone Screen Testing technology could be a lifesaver. Researchers from University College London (UCL) analyzed samples obtained from people’s mobile screens using the approach. According to the researchers, people who have tested positive for the Covid-19 on a regular nasal swab RT-PCR test were also positive when samples were collected from their smartphone screens.

 

According to research printed in the journal e-life, ongoing surveillance would be required to keep SARS-CoV-2 from spreading, especially given the advent of novel variations that could thwart vaccination attempts. According to the researchers, it could aid in the containment of Covid-19 outbreaks and discover potentially dangerous variations in the future.

To identify the existence of the virus, a small amount of DNA is taken using a swab. A nasal swab or an oral swab can be used (through the throat). The test, however, can only detect the presence of the virus and cannot determine whether or not someone has recovered from Covid-19.
