“Once it gains entry to the ear, the virus can actively infect both the cochlear (hearing) and vestibular (balance) hair cells, potentially causing:
Sensorineural hearing loss. Hearing loss caused by damage to the inner ear or the nerve from the ear to the brain. This type of hearing loss is permanent. Vestibular dysfunction: Problems with balance. In addition, COVID-19 is not just a respiratory disease. It can affect almost all of the major organ systems in the body, including the vascular system. "
SARS-CoV-2 infection of the inner ear
SARS-CoV-2 can infect inner ear cells, specifically hair cells and Schwann cells, which are crucial for hearing and balance.
Some COVID-19 patients developed hearing loss, tinnitus, and vertigo, suggesting a link between the virus and these symptoms.
