Woman loses hearing in one ear after mild Covid-19 infection
A woman identified as Meredith Harrell lost her hearing in one ear after mild Covid-19 Infection.
According to Elizabeth Cohen, CNN Senior Medical Correspondent, Harrell was walking from her backyard into the house, her right ear suddenly started to ring.
She realized that, other than the ringing, she couldn’t hear anything out of that ear.”It was like someone flipped a switch,” she said.
Harrell’s hearing loss was a mystery until about a week later, when she took a Covid-19 test. It was positive.
Even though she never felt sick, an otologist — a doctor who specializes in hearing — explained to Harrell that the virus was likely the culprit.Meredith Harrell with her son, Mason. The family tested positive for Covid-19.
Viruses such as measles, mumps and meningitis are known to sometimes cause sudden hearing loss, and there’s growing evidence that the novel coronavirus should be added to the list.
“We’re hearing more and more that people have hearing loss as part of their Covid infection,” said Dr. Matthew Stewart, associate professor of otolaryngology at Johns Hopkins Medicine.
There are no statistics on how common it is for people who’ve had Covid-19 to experience hearing loss, but a few small studies point to a possible link.
A team in Manchester, England, asked Covid-19 patients eight weeks after they’d been discharged from the hospital whether they’d experienced any hearing changes or ringing in their ears.
Of the 138 patients in the study, published in the International Journal of Audiology, 13% said yes.
He said the reason is that the coronavirus is known to cause blood clots in other areas of the body, and he thinks that could be happening in the “extremely small blood vessels” in the inner ear.
Kevin Munro, an audiological scientist who co-authored the study in Manchester, said he thinks that theory makes sense.”
The capillaries in the inner ear are the smallest in the human body, so it wouldn’t take much to block them,” he said.
Munro and his team at the University of Manchester are planning larger studies on Covid-19 and hearing loss.
Until then, they’re not sure why it seems like some Covid-19 patients develop hearing loss while others don’t.
