Orientation to diagnosis
In Europe, in mild to moderate forms of Covid-19 infection, a multicenter study identified 54% of patients with taste disturbances. (1)
The taste measurement in Covid patients would therefore allow:
○ Early identification of the first clinical signs of infection and referral for diagnosis
○ Accuracy of a taste disorder and referral to additional and more expensive tests to validate a COVID-19 diagnosis
○ Helps in the gradation of disease severity upon diagnosis.
Long COVID patient follow-up
20% of Covid-19 patients are affected by long COVID (a form of Covid with prolonged, fluctuating and multisystem symptoms). Among these patients, 30% present a taste loss. (2)
The taste measurement for long Covid patients would allow:

○ Patient follow-up
○ Monitoring the disease severity
○ Monitoring of disease progression and sensory symptoms according to taste and olfactory rehabilitation protocols.
