Challenges with Early Screening for COVID-19

There needs to be a better way to test quickly and comfortably
N
Inaccurate results with low and medium viral infections (viral loads)
N
Uncomfortable, kids resist
N
Accidents can and do happen
N
Expensive personnel costs to administer and manage
N
Too time consuming to administer at events and public venues
N
Difficult to get accurate data into cloud reporting systems

The Timing of COVID-19 Symptoms

Cough

(starts from day 5-6)

Fever

(starts from day 5-6)

New loss of taste or smell*

(starts from day 1-3)

Muscle aches

(starts from day 5-6)

Vomiting or diarrhea

(starts from day 5-6)

The COVID-19 Testing Gap…

thermometers

Thermometers:

Fever appears after day 5-6 in only 60-70% of population.

Inexpensive but little value as people with fever and other symptoms usually stay at home.

antigen-testing

Antigen Testing:

Most accurate on symptomatic people from week 2 after infection

Not accurate in the first week after infection.

Expensive to administer and get data into the cloud.

pcr-testing

PCR Testing:

Gold standard but very costly & time consuming to detect low viral loads.

Primarily used by doctors for diagnosis, not a good fit for early screening.

The current testing methods do not properly screen for asymptomatic people.

Why the Sense of
Smell Is Impacted
First By SARS-CoV-2
N
Virus enters nose cavity and accumulates in ACE2 Receptors
N
From Day 2 your sense of smell is compromised 
N
Human brain does not recognize this at first
N
Smell tests can detect this partial smell loss called hyposmia
How it works?
A paper card is provided with very specialized smells proven to be associated with COVID-19 and optimized by region/ethnicity. 
Users scratch and smell. Based on years of research, the test checks for hyposmia (partial smell loss) which is discernible in the early stage of COVID-19. 
A short questionnaire is completed and then processed using AI to issue a PASS or FAIL to the user.

Testing Frequency Protocols
1910.501(g)(1)(i)An employee who reports at least once every 7 days to a workplace where other individuals such as coworkers or customers are present: Must be tested for COVID-19 at least once every 7 days; and
1910.501(g)(1)(i)(B) Must provide documentation of the most recent COVID-19 test result to the employer no later than the 7th day following the date on which the employee last provided a test result.
Vaccination status should not affect the results of viral testing for SARS-CoV-2.
Given that the incubation period can be up to 14 days, CDC recommends conducting screening testing at least weekly.
Routine asymptomatic testing strategies for COVID-19 have been proposed to prevent outbreaks in high-risk healthcare environments. We used simulation modeling to evaluate the optimal frequency of viral testing. We found that routine testing substantially reduces risk of outbreaks but may need to be as frequent as twice weekly.
