Identifying Asymptomatic SARS-CoV-2 (Covid-19) Individuals

SARS-CoV-2 (Covid-19) continues to disrupt our lives globally. Vaccine deployments are turning the corner but new variants pose threats now and for our future.

The primary way to curb the uncontrolled spread of SARS-CoV-2 (Covid-19) is to identify asymptomatic/sick individuals at border crossings, travel hubs, facility checkpoints, and at healthcare facilities and restrict any vectors for further infection.

Before the emergence of SARS-CoV-2 (Covid-19), our team was researching diseases and their symptoms. With SARS-CoV-2 (Covid-19) rapid emergence to that of pandemic levels, our company’s findings seem ever more relevant in the current climate.

In February 2020 we focused on SARS-CoV-2 (Covid-19) and how we can use our UID Health Identity biometrics technology for the SARS-CoV-2 (Covid-19) pandemic. Our team discovered that with the right technology, we can identify infected asymptomatic people with NIR or Chemosensory (smell) as we noted I our US Patent 10,880,303

Thanks to our teams' groundbreaking work for the detection of SARS/Covid, we have identified the chemical odor signature or chemosensory associated with the metabolism of SARS/Covid infection. We have been working with hardware partners for most of 2021, we feel this can be the world's first fully automated SARS/Covid detection system that can clear a person as Covid free in 3-5 secs using just smell at airports, cruise lines, etc.

Combined with our artificial intelligence (A.I.) methodology relies on near-infrared *(NIR), Ultrasound, and/or chemosensory detectors, trained with a library of normal morphology and known SARS-CoV-2 (COVID-19) infection attributes, to compare individuals scanned in real-time to identify infected individuals, even if asymptomatic, for referral for further, confirmatory testing.

Symptoms Invisible To Temperature Checks But Visible To UID™

UID™️ is a unique method that requires no temperature checks (which have been proven to be of little use in catching asymptomatic SARS-CoV-2 (SARS-CoV-2 (Covid-19) super-spreaders. It’s been proven that such people can circumvent temperature scanning using fever-suppressing medication such as Paracetamol/Tylenol or other NSAIDs to reduce fever like symptoms.

UID™️ is used for vascular identity, we found it can also look within the vasculature for blood flow constriction and/or reduction of flow of oxygenated hemoglobin that then shows up as reduced vascular clarity when the person is infected with SARS or COVID. Clean healthy blood flow, in contrast, would be full of oxygen if depicted in a 3D NIR of the finger.

Rapid Screening

Using our custom NIR, infected asymptomatic individuals when scanned would show up as half black, thus reduced oxygenated hemoglobin (an almost black image is clearly defined as sick or lacking proper oxygen levels). Compare to healthy flow of oxygenated hemoglobin in figure 3.

An organization can very quickly, scan every person at airports in all countries. This technology quickly identifies the typical attributes of the infection prior to passenger boarding the airplane or leaving the arrival gate reassuring authorities that the passenger is not infected with SARS-CoV-2 (Covid-19) or requires additional testing and quarantine. This can be deployed inexpensively at all offices and buildings on a global scale.

The future is an easy to use scanning method for asymptomatic individuals

Our testing as of 4th quarter 2020 with a government agency involved over 100,000 individuals, with an accuracy of 99% in identifying sick-symptomatic, infected-asymptomatic, and healthy individuals during our identity screening for UID™️. Any infected-asymptomatic or sick individuals were then verified with a clinical test if they scanned positive for SARS-CoV-2 (Covid-19) in the pre-screening using our NIR or chemosensory system.

As always, we recommend you run your own NIR or CMUT tests to see that this will work and design your AI to look for the attributes of the infection, then deploy the method and open up the world to HELP to stop the SARS-CoV-2 (Covid-19) spread.


Our U.I.D.™ system can be deployed in almost anything that you currently interact with on a daily basis and/or used to automate health monitoring and identification — saving millions of lives when the next healthcare disaster strikes.
