A large number of patients reported hearing loss weeks after recovering from COVID-19, a team of audiologists have reported.
The researchers ran a telephone survey involving 121 adults admitted to Wythenshawe Hospital, UK. The researchers asked the COVID-19 survivors about any changes they’ve noticed since discharge, and sixteen (13.2%) of them reporting having hearing difficulties, while eight people reported hearing unusual drumming sounds in the ear.
The researchers say the hearing loss may be as a result of direct damage of the cochlea, which converts sound waves to nerve signals for transmission to the brain, and the auditory nerve, which transmits sound impulses to the brain for processing.
The researchers say these findings add to the growing body of evidence suggesting that COVID-19 has long-term effects even long after recovery from the infection.
