Since the start of the COVID-19 pandemic, perhaps no symptom has been in the spotlight more than loss of smell. How does COVID-19 cause people to lose sense of smell? And how many regain it?

Dr. Sandeep Datta, associate professor of neurobiology in the Blavatnik Institute at Harvard Medical School and senior author of the study, said that when sustentacular cells are damaged, they are capable of regenerating and regaining their function.

However, it can take weeks or months, which may explain why many people don't recover their sense of smell for several months.In addition, afrom December 2020 suggested loss of smell may be from COVID-19 causing inflammation and bleeding in the part of the brain -- known as olfactory bulbs -- that controls sense of smell.

"It's not clear whether the virus enters into the olfactory bulbs or not -- that's still a question -- but many other viruses do," Dr. Richard Doty, a professor in the department of otorhinolaryngology-head and neck surgery at the University of Pennsylvania, told ABC News."Even the herpes virus can get into the brain through the olfactory pathway, so it's not beyond a possibility.

Turner said he believes that stories about anosmia have brought a newfound appreciation for sense of smell to the general public. "We typically underappreciated this sense because we may not appreciate that we're using it as much in our daily function," he said."It's not until it's lost that we recognize how important it is."
