Detect COVID-19 with Your Smartphone Camera? Scientists Make It Possible


Smartphone cameras can do way more than just take pictures or video, as we have covered here on many occasions.

But we didn’t expect them to be enlisted in the global fight against COVID-19 yet that’s happening and it could be a big boon for detection and prevention, Forbes reports.

From Forbes:

“The system uses a hotplate, cell phone, a 96-well plate, LED lights, and a chemical assay, all of which can be put together for $100. The chemicals required are mixed with saliva and placed in a well of the plate, which is much like miniature egg cradles in cartons, except that there are 96 per plate. The plate is warmed on a hotplate. A smartphone can read the chemical reaction and a diagnosis is available in only 25 minutes. Each test will cost $7, compared to $15+ for rapid antigen test kits and $100+ per PCR test.”

The setup here sounds similar to the diabetes detection system we covered in 2019. There, smartphones were being used to detect changes in blood flow, specifically whether an “app could detect changes in blood flow using a smartphone camera and photoplethysmography (PPG) signal.”

Of course, smartphones aren’t the only devices that are finding use in these areas; many smartwatches have a range of health-related functions that may be of benefit to the user.

Back to the COVID-19 detection system, Forbes reports that the major benefits of it include its cheap operating cost and ease of use as well as its strengths in detecting asymptomatic infections. Implicit in this, naturally, is that quicker detection of asymptomatic cases could assist with more effective quarantine procedures for at-risk people. And all with the use of a smartphone.
