A new study says that there is evidence to suggest that there is an association between Covid-19 and tinnitus, hearing loss and others.

Researchers believe they have identified yet more symptoms linked to coronavirus.
A study, published in the International Journal of Audiology, discovered that hearing loss and other auditory problems could be associated with the deadly virus.
Experts were able to isolate 56 papers that found an association between Covid-19 and a range of auditory problems, reports Wales Online.
Three hearing problems among those said to be linked with Covid include tinnitus, hearing loss and vertigo.
The only official symptoms of the virus are currently: loss of taste or smell, continuous cough and a high temperature.
But 25 studies out of the 56 researched estimated that the prevalence of hearing loss was 7.6%, tinnitus was 14.8% and vertigo was 7.2%.
However, the team who followed up their review carried out a year ago described the quality of the studies as ‘fair’.
Their data primarily used self-reported questionnaires or medical records to obtain Covid-19-related symptoms, rather than the more scientifically reliable hearing tests.
Kevin Munro, professor of audiology at The University of Manchester and Manchester Biomedical Research Centre (BRC) hearing health lead, said: There is an urgent need for a carefully conducted clinical and diagnostic study to understand the long-term effects of Covid-19 on the auditory system.

It is also well-known that viruses such as measles, mumps and meningitis can cause hearing loss, little is understood about the auditory effects of the Sars-CoV-2 virus.
Though this review provides further evidence for an association, the studies we looked at were of varying quality so more work needs to be done.
Prof Munro is leading a year-long UK study to investigate the possible long-term impact of coronavirus on hearing among people who have been previously treated in hospital for the virus.
His team hopes to accurately estimate the number and severity of Covid-19 related hearing disorders in the UK, and discover what parts of the auditory system might be affected.
