Details  1. Symptomatic COVID19 positive patients, not critically ill or on ventilator, of any age/ sex and their relatives.
2. At risk individuals in quarantine (relatives and contact of positive individuals, symptomatic or asymptomatic) will also be recruited
3. As stated above sample size will be 300 initially irrespective of age/sex (no direct ratio) of the individuals
 
 
ExclusionCriteria 
Details  1. Critically ill or on ventilator COVID19 positive patients, will be excluded.
2. The patients on a regular medication with probability of loss of smell and taste sensation will be excluded. Their history of any comorbidity which is related to smell sensation will be taken into account.

Primary Outcome  
Outcome  TimePoints 
Economical, rapid, Make in India, a five-minute odor test that can present the identification, discrimination and thresholds of odor perceptions as a detection of suspected cases of COVID 19.
Sensory capabilities of COVID positive patients get damaged and thus can be used as tool of diagnosing infected / symptomatic COVID subjects  
The new diagnosed COVID positive cases will be tested will our odour test. Whereas those quarantined shall be monitored only after confirmation of their corona test report.

The odour test may be repeated on the recovered COVID patients either immediately or later.  
 
Secondary Outcome  
Outcome  TimePoints 
If we could do, the study may give correlation of genomic attributes of virus or mutations in relation to disease presentations.  Such analysis will be conducted at approx 6th months or after the study

Brief Summary  

Rapid spread of the SARS-CoV-2 virus and concern for viral transmission by ambulatory patients with minimal to no symptoms underline the importance of identifying early or subclinical symptoms of Covid-19 infection. Two such candidate symptoms include anecdotally reported loss of smell (anosmia) and taste (ageusia). Available literature as well as WHO guidelines have enumerated smell and taste loss as one of primary and initial symptoms of infection. 

Our group here at NABI is working on the sensory receptors TRP channels since last 10 years with the question that how do we sense food and what are its implications in obesity and type-2 diabetes. During that time, we have been able to work with spices and herbs with unique and characteristic odour. Using our understanding of chemosensory mechanisms, the characteristic smell of herbs/spices commonly present in our kitchens and the understanding that every Indian is aware of smell/odor of spices we will develop (economical, rapid, Make in India) a five-minute odour test that can determine the identification, discrimination and thresholds of odour perceptions (can be positively related to taste loss) which on validation, may be an early indication of COVID-19. Given the non-availability/expensive nature of testing kits, this test if passed through will enable us do rapid and wider testing. In addition to this, this test has a potential to be one of the scanning tests along with temperature sensation (thermometer) at the entry points of hospitals, government and private offices, shops and other places of public dealing in order to have a safe cordon.


Diagnosis: Recruitment of participants

  1. The patients already diagnosed positive for COVID19 and are in PGIMER facility will be recruited for this study whereas their healthy relatives or other normal individuals will be screened for COVID19 by using confirmatory test through real-time PCR. For supporting the study outcomes, the clinical samples and RNA samples can be used for any genomic approach and association/ correlation with our test results.
  2. At risk individuals in quarantine (relatives and contact of positive individuals, symptomatic or asymptomatic) will also be recruited. In their case, these will be screened for COVID19 by using confirmatory test through real-time PCR. This will enable us to correlate our smell test results with other symptoms.

In total 100 COVID19 positive individuals and 100 at risk quarantine will be recruited. Also, 100 healthy individuals (COVID19 negative) will be recruited to understand that our smell panel is easily detectable by normal healthy individuals.

Hence, study groups will be:

                                 I.         COVID19 positive group (N=100).

                               II.         At risk quarantined individuals (N=100).

                             III.         Healthy individuals (negative for COVID19) (N=100).
