Yes, there have been reports and studies suggesting that COVID-19 can cause hearing loss. While it is not a common symptom of the virus, some individuals have experienced sudden hearing loss or a worsening of existing hearing loss after contracting COVID-19. The exact mechanism behind this is still being investigated, but it is believed that the virus can cause inflammation and damage to the auditory system. If you or someone you know experiences any changes in hearing after a COVID-19 infection, it is important to seek medical attention and consult with an audiologist for further evaluation and treatment.
