San Diego, Apr 15: Several people lost their sense of smell or taste weeks ago globally and are still waiting for it to come back and now, researchers have identified an association between sensory loss and novel coronavirus 2019 (COVID-19) infection, indicating that loss of smell and taste may be considered as early symptoms of the deadly disease.
Interestingly, the study also found that persons who reported experiencing a sore throat more often tested negative for COVID-19.
The team from University of California-San Diego found high prevalence and unique presentation of certain sensory impairments in patients positive with COVID-19.
Of those who reported a loss of smell and taste, the loss was typically profound, not mild.
"Based on our study, if you have smell and taste loss, you are more than 10 times more likely to have COVID-19 infection than other causes of infection. The most common first sign of a COVID-19 infection remains fever, but fatigue and loss of smell and taste follow as other very common initial symptoms," explained study researcher Carol Yan from UC San Diego.
"We know COVID-19 is an extremely contagious virus. This study supports the need to be aware of smell and taste loss as early signs of COVID-19," Yan added.
For the findings, published in the journal International Forum of Allergy and Rhinology, the research team surveyed 1,480 patients with flu-like symptoms and concerns regarding potential COVID-19 infection who underwent testing at UC San Diego Health from March 3 through March 29, 2020.
Within that total, 102 patients tested positive for the virus and 1,378 tested negatives. The study included responses from 59 COVID-19-positive patients and 203 COVID-19-negative patients.
Encouragingly, the rate of recovery of smell and taste was high and occurred usually within two to four weeks of infection.
"Our study not only showed that the high incidence of smell and taste is specific to COVID-19 infection but we fortunately also found that for the majority of people sensory recovery was generally rapid," said Yan.
"Among the COVID-19 patients with smell loss, more than 70 per cent had reported improvement of smell at the time of the survey and of those who hadn't reported improvement, many had only been diagnosed recently," she added.
Sensory return typically matched the timing of disease recovery.
In an effort to decrease the risk of virus transmission, UC San Diego Health now includes loss of smell and taste as a screening requirement for visitors and staff, as well as a marker for testing patients who may be positive for the virus.
"It is our hope that with these findings other institutions will follow suit and not only list smell and taste loss as a symptom of COVID-19, but use it as a screening measure for the virus across the world," Yan said.

Hats off to the above teamwork
A wonderful selfless act. He must have been a compassionate person.
Oh, my heart breaks for the family. My family also had to make the decision to donate my niece's organs. For me personally it was one of the most healing things knowing she had saved so many lives but I do often wonder how/where these people are.
Selflessness - the stuff of real heroes.
As a recipient of a heart just over two years ago I am eternally grateful for those who make this decision. I can continue to be a son, a husband, and a father to two small children.
My brother passed unexpectedly on 24th February 2015, he too donated his organs. His selfless act has helped us, as a family to know he breaths through another & has assisted at least four other recipients & their families last year. We would love to reach out to the recipients on his 1yr memorial but understand the sensitivity for some and respect their privacy but it's hard.... I know it would mean the world to mum & dad to meet them & would greatly assist in their healing. I wish there was a 'tick box' option to opt in for communication between families.
My deepest condolences to his family and friends on his passing. Organ donation is a befitting gesture to honour this young man. With much love to you all at his difficult time.
Feel sorry for the man and his family...life is unpredictable.
RIP!!! You r a real hero buddy...
these idiots will construct green corridors with lot of potholes. do practical and proper work rather than bs talk
Why drones flying at low heights in some Specific colour can not be used for Organ Transportation?
At times the Mangalore Police makes us proud and kudos to the team that coordinated with the transplant team of one and all.
Very good. Appreciated the good work Police department
he has shown that humanity does still exist in India. well done,. May Almighty Bless him , this deceased Son as well as the patients who received the organs. Kudos ot medical fraternity along with police who made this happen
