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.

I dont understand, why media giving attention to this rubbish speech.. He just wanted media attention. and also he wanted to thrill his followers..
Nalin Kumar Kateel is no. 1 terrorist. Once he told, he wanted to burn entire Mangalore.
Shakha trained bhakt ! Modi & Shah are very happy on his comment on CM. Nalin Don't worry you are eligible represent educated Mangalorean (?) in forth coming Parliament election -2019.
This kateel is delivering an election speech or mocking himself?
An uneducated goon who threatened to set entire Dakshina Kannada district on fire is a desh bhakt. And a farmers’ leader turned politician who upheld the concept of Kalnaya Rajya is a terrorist. What a joke.
Katilanna.. First learn language. The meaning of Sultan is King. You are hailing him as king. King will be terrorists for only terrorists.
I think politics of this region is a curse. There is no boundries to the wild allegation and lies that these politicians utter. I think we have to play back some of his terrorism speeches including burning of DK speech.
The only way we can stop BJP getting back to power in Karnataka is to switch to ballot system.
What they think they can fool all Kannadigas, as they did in North East, UP.
Unfortunately the people in that regions are very innocent. They don’t understand how they are being fooled by their leaders specially Modi and Amit Shah.
Now their own people are fed up of them. Many secular leaders left the BJP and jointed Congress.
Kateel is very lucky to be a MP who really does not deserve to be Grama Panchayat member.
The cleanest CM is Siddaramiah, in the recent generation, like very few CM s we had in the past like Nijalingappa, Kadidal Manjappa. He never indulged in single bribery or corruption.
He is Very straight and strong leader, who has always worry for the people. But our stupid opposition want to destroy him for their selfishness at the cost suffering of poor people.
May God almighty help our people to understand the fact and elect the best leaders.
