People who have tinnitus will hear ringing in their ears.
REPUBLIKA.CO.ID, JAKARTA – Most of the symptoms of Covid-19 cause a person to just want to curl up in bed and rest. Some of the more common symptoms include sore throat, headache, and feeling tired. In addition, there are other symptoms that affect the ear, but they are less well known.
During the pandemic, there were a number of Covid-19 sufferers who complained of hearing loss, including tinnitus. People who experiment tinnitus he will hear a buzzing from his own ear, not from an external source.
Many experts speculate that this means Covid-19 can affect the inside of the ear. To corroborate this conjecture, researchers from MIT and Massachusetts Eye and Ear published the results of their study in the journal Communications medicine.
In their study, the research team analyzed human ear tissue. The researchers found that hair cells and Schwann cells in the inner ear express a protein necessary for SARS-CoV-2 infection, making them potential targets.
It is not clear how Covid-19 enters the inner ear. The research team suspects that the virus may enter through the nose, which is a structure located in the forebrain, or the endolymphatic sac, which describes the protective pad between the inner ear and the rest of the body.
Research also predicts that infection and damage to inner ear hair cells may be at the root of hearing problems reported by some patients with Covid-19. Other studies have also highlighted the ear symptoms associated with the coronavirus.
