So, i have had total loss of taste and smell 7 days ago, and did test positive for covid 2 days ago. how long before my sense of taste and smell return? so scared it's permanent?

Don’t know: Predicting when your symptoms will resolve is difficult as different folks recover differently. Often 10-14 days will allow sufficient recovery of taste/smell but others have the symptoms much longer. Good luck

Unknown answer: There is no way to determine an answer to this question as each COVID symptom affects each patient differently.

Anosmia: no smell: Persons who have inosmia are positive for corona Virus 80%. Persons with loss of smell and taste have mild disease compared to those who maintain taste and smell. This loss occurs as corpuscles which sense are destroyed but these neurons regenerate and one can feel smell & taste. Regeneration is variable : protracted in some cases, Recovery is a real possibility, gradual improvement is expected.

Usually returns: Although it is difficult to fully predict, in most cases gradual return of taste and smell occurs within a few weeks, and by far, most patients have recovered by 3 months.
