While scientists are busy developing coronavirus vaccines, biotech firms think there might a better preventive solution. The question on their mind is: can biometrics detect Covid-19 in asymptomatic patients. Most Covid-19 patients do not show any prominent symptoms.

This means, a patient of Covid-19 can travel places undetected, spreading the virus to more innocent people along the way. Some patients show mild symptoms. Without a test, even doctors may confuse these symptoms for common cold. As a result many asymptomatic patients don’t know they have been infected.

However, the research on the use of biometrics for scanning such pathogens is going strong. If everything goes according to plan, biometrics will detect even the most asymptomatic of coronavirus cases.

Biometric technology for coronavirus

To prevent asymptomatic patients from spreading Covid-19, Biometric companies and experts are suggesting the use of biometric technology. Airports can benefit the most from this technology as they cater to a large population of people, connecting them to the rest of the world.

Similar to body scanners at security check, biometric health scanning systems can be set up at airports. This way authorities can scan the people who appear healthy to check for asymptomatic coronavirus.  In 2021, 650 million passengers travelled all over the world through airports. If biometric scanners are implemented, more countries will open up their international travel. Currently, they are afraid of causing another coronavirus outbreak in their society.

Temperature scans are limited

The present biometrics emphasize temperature scans more. But temperature alone is not accurate enough for the diagnosis of an asymptomatic patient. However, the alternative to temperature scans should continue being non-invasive. Otherwise, the scans will not be fast enough to be useful. Imagine forming long queues at the airport.

Biometric companies are proposing two solutions for this –

  • NIR (Near Infrared Light) Transducer
  • CMUT (Custom Designed Ultrasound) for biometric identification in multi-modals.

Biometric scan mechanics

This is how biometric scans will work – travellers get their vascular network scan for identity confirmation. When that happens, NIR and CMUT technologies will look for alterations in their blood vessel morphology and oxygen-carrying capacity. In asymptomatic Covid-19 patients, both these metrics are reduced. People who show reduced blood vessel morphology and oxygen-carrying capacity will then undergo RT-PCR for confirmation.

This technology is still being developed. Once it is implemented, this technology will ensure that Covid-19 does not spread to other places, keeping everybody safe.
