Loss of smell and taste are among the well-known coronavirus symptoms. Scientists may now have come across a new sign that paralyzes another sense organ. However, the cause of its occurrence has not yet been clarified.
In a study published in the International Journal of Audiology in July, the study directors explain the results of a study of 121 coronavirus patients. The data used are based on the analysis of a study published in JAMA Otolaryngology.
As British scientists have reported, hearing loss and tinnitus, which are constant or seizure noises in the ears, could be the latest coronavirus sign to emerge after a Covid-19 illness. So far, however, researchers are still puzzling over whether the corona symptom is triggered by a direct infection via the ear or whether other factors lead to hearing damage.
Tinnitus and hearing loss
All infected were patients with a severe course of the disease. It turned out that some of them experienced hearing loss or tinnitus eight weeks after leaving the hospital.
It is not yet known whether it is a side effect or an actual infection of the ear caused by the coronavirus infestation. Finally, tinnitus and hearing loss can also be caused by other activities such as therapy. It is known, however, that other viruses have the ability to attack other areas of the body. “We already know that viruses like measles, mumps and meningitis can cause hearing loss, and coronaviruses are able to damage nerves that carry information to and from the brain,” Professor Kevin Munro of the University of Manchester told Bestlifeonline. “It is possible that Covid-19 causes problems with parts of the hearing system, including the middle ear or the cochlea,” continued Munro.
