Eligibility

Inclusion criteria

Inclusion criteria: 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

Exclusion criteria

Exclusion criteria: 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. 3. Those addicted to the chewing paan and similar materials will be excluded.

Design outcomes

Primary

MeasureTime frame
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 subjectsTimepoint: 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

MeasureTime frame
If we could do, the study may give correlation of genomic attributes of virus or mutations in relation to disease presentations.Timepoint: Such analysis will be conducted at approx 6th months or after the study
