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.

saudi bopanna ka bap ka hai. And who are you to say whether it is a muslim country or not. boppa
Saudi tere bap ka hai Kya ? Saudi is NOT Muslim country,.
YES WE ARE WITH YOU
Exactly. this is the fake encounter and cops deserve the death penalty.
Katju rightly said. Murderers along with masterminds deserve it.The trend of fake encounters has to be stopped in future.
Yes, many Indians believe that it was custodial killing/fake encounter, and a good majority also agree with Katju. All these Indians, including Katju - A former supreme court judge, are Anti-Nationals.
Sanghi chappars calling a qualified Rtd. chief justice of supreme court \Desh Drohi\". I mean why do people even respond to such comments and trolls.
None the less, Katju is also against many Islamic values and practices. But in this case, he has raised his voice for justice."
#2 Bopanna, KSA
What are you doing in KSA? It is a muslim country and is it allowed to you to work there? How can you feed your family in the wealth which is earned in muslim country. You hate Ummah then in this case you are a hypocrite.
Remember this soon or later truth will prevail and that time you will be sad. In your view if Justice Katju is desh drohi then what about Praveen togadiya, Karnal purohith, sadhvi prajna, Swami asimanad and other all sangi terrorists??
You are right Mr.katju. Guys look @ video, and suspects prisoners were raising hands for surrender. But cops deliberately fired at them. And if you watch last night debate with bloody BJP spokesperson the way of answering was very shameful. Just they were struggling to answer the TV anchors questions.
Bopanna, if it had happened to you or any of your family member you would have felt the same thing.....no one has proved them guilty....they were under trial...police are not doing their job...instead encountering them by putting Simi tag....it is not good for a democratic country like India.....
How much does the Ummah pay you for such statements?
This guy is a Desh drohi
Death penalty for COPS in India !!!!!!!!!.....Forget it man
