Figure 5. — This chart represents the recovery in all patients who had COVID-19 and olfactory dysfunction (OD). Out of 207 patients with a recent history of OD, 138 cases reported a nearly or fully recovery (66.6%) before the time of presentation to referral centres. In these patients, OD was reported as a primary symptom. Sixty-nine patients still had OD when they presented to referral centres. Therefore, they were assessed for a 1-month follow-up prospectively. In this subgroup, 41 patients (59.4%) were nearly or fully recovered after 1 month. In total, 179 patients (86.4%) were recovered from OD approximately a month after the onset of OD. *These patients reported OD as a primary symptom (a recent history of OD) along with other COVID-19 symptoms. Although OD was recovered when they presented to the referral centre, they still had other COVID-19 symptoms and a positive test for COVID-19.
