New British studies shed light on symptoms that may be linked to Sars-CoV-2 infection. Scientists estimate, in fact, that 7.6% of infected people suffer from hearing loss, while 14.8% experience episodes of tinnitus. The same scholars also argue that the presence of dizziness occurs in 7.2% of cases.
Researchers fromManchester University he was born in Manchester Biomedical Research Center therefore analyzed the data of 24 studies that identified an association between coronavirus and hearing and vestibular problems. The collection of this data, aimed at verifying the presence of auditory symptoms related to the coronavirus, was carried out using mainly self-completed questionnaires or medical records, rather than hearing tests, which is why it will be necessary to carry out further investigations in order to be able to give to all this an effective scientific foundation.
It is not known why Covid-19 can cause these hearing problems but a wide variety of people are believed to have been affected. “Some subjects reported that the symptoms were still ongoing. According to others, however, they seemed to have calmed down a bit, so there are still many unknowns at this time, “Professor Kevin Munro, director of the Manchester Center for Audiology and Deafness. “However. While it is true that between 7 and 15 percent of patients are having these symptoms, it is something we should take very seriously, ”he added.
Generally, Hearing problems are known to be caused by other viruses, including measles, mumps and meningitis, which damage the sensory cells of the inner ear. UK scientists are now conducting a more detailed clinical study which they hope will accurately estimate the number and severity of Covid-19-related hearing disorders.
