[Dizziness and hearing loss in healthcare workers with COVID-19]

Coronavirus disease 2019 (COVID-19) affects the respiratory system. Studying the clinical characteristics of this infection has revealed its tropism to the nervous system, which is responsible for neurological and sensory damage, in particular, dizziness and hearing loss. To determine the frequency and characteristics of the neurological impairment represented by dizziness and hearing loss in healthcare professionals (HCP) with COVID-19. Cross-sectional descriptive study conducted among HCP at Charles Nicolle Hospital (CNH) in Tunis affected by COVID-19 during the period from September 2020 to December 2020. Data collection was carried out by regular telephone follow-up of COVID-19 symptoms in these HCPs during the period of sanitary isolation. A total of 482 HCPs with COVID-19 were collected. The average age of the population was 41 ± 10 years, of which 111 were men (23%) and 371 were women (77%). The main neurological manifestations were: headache (71.2%), anosmia (60%), dizziness (21.8%), and hearing loss (1.5%). Patients with vertigo were significantly older (P=0.035), female (P=0.003), obese (P=0.014), suffering from more comorbidities (P=0.004), and having greater professional seniority (P=0.009). Dizziness was significantly associated with fever (P=0.001), abdominal pain (P=0.001), and desaturation (P=0.039). Neurological symptoms including dizziness and hearing loss may be the only sign with which a case of COVID-19 could be recognized. Raising awareness of such a presentation of COVID-19 patients is crucial during this pandemic period to prevent infectious spread, especially in hospitals.
