INTRODUCTION: The pathophysiology of COVID-19 is evolving. We investigated self-reported sudden loss of sense of smell and taste, and otologic disorders among COVID-19 patients.
METHODS: This was a case-control olfaction, gustation and otology study of COVID-19 RT-PCR tested adults. The study took place at the isolation centres for COVID-19 positive individuals in Abuja and Ibadan, among the epicentres of the disease in Nigeria. The participants were 46 COVID-19 positive adults and 46 COVID-19 negative adults. They responded to a validated online questionnaire-based on olfactory, gustatory and auditory loss. Chi-square tests and correlation analysis was done. Level of significance was at P<0.05.
RESULTS: Among cases, sudden loss of smell, taste and hearing were reported by 14 (30.4%), 8 (17.4%) and 5 (10.9%) cases respectively during the COVID- 19 infection. First symptom was loss of smell in 7 (15.2%) and loss of taste in 2 (4.3%) cases. The controls did not present with any of the symptoms. There was no significant correlation between loss of smell and age (r = 0.023, p=0.879); sex (r = -0.132, p=0.382) and co-morbidities (r = -0.028, p = 0.857). Similarly, there was no significant correlation between loss of taste and age (r = 0.052, p = 0.732); sex (0.040, p = 0.792) and co-morbidities (r = -0.014, p = 0.925).
CONCLUSION: Sudden loss of smell and taste are commoner among COVID - 19 positive adults than those without the infection in Nigeria. There is evidence of associated reduction in hearing acuity but further study with objective audiometric testing is recommended.
