The coronavirus, covid-19, could cause a sudden and definitive deafness, this was stated by a medical group, reporting the British “first case” in the magazine BMJ Case Reports.
It is, however, a very rare symptom among the string of potential effects of covid-19.
“Despite considerable documentation on covid-19 and the various symptoms associated with the virus, there is a lack of debate about the relationship between covid-19 and hearing“These experts warn in the specialized magazine, recommending that tests be carried out in hospitals, even in intensive care, to apply steroid-based treatment if necessary.
So far, only several cases have been reported in the world and the study authors report on a 45-year-old man treated for COVID-19 at his British hospital.

The patient, who also suffers from asthma, was admitted to intensive care, under artificial respiration. The doctors gave him a treatment based on remdesivir (an antiviral), steroids and an exchange of blood plasma.
His condition improved, but a week after leaving the intensive care unit, he suddenly became deaf in his left ear. Tests determined that his ducts were not blocked and his eardrums were intact. He was treated with corticosteroids but only partially recovered.
After ruling out other possible causes, doctors associated this hearing impairment with COVID-19, according to the magazine. A first similar case was announced in April 2020 in Thailand.
The article’s authors note that SARS-CoV-2, which is installed in a particular cell type found in the lungs, was recently found in similar cells in the ear. This virus also generates an inflammatory reaction and an increase in the production of cytokines (a type of protein) involved in hearing loss, according to the authors.
