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.

The actual FACT is during Independence and Partition of India & Pakistan, British as usual left a piece of land so that there will be no peace between India & Pakistan (in-case if they join Hands they will become Super Power of the World). The only solution for Peace to Prevail is leave Kashmir to their people. Let them decide which part of Kashmir they want to stay, make partition, I know this won't be done as for political GAINS, Let the families of Politician start living in Kashmir and feel how it is to lose a loved ones. Just by blaming Pundits and Muslims wont work. Killing innocent people by either side is just to brainwash the Public and to keep the rivalry alive on the basis of religion and country.
Malala , you have yourself experienced how inhuman and ruthlessly atrocious Pakistan Government is. As they manipulated you and your family’s circumstances to harass, they are exploiting and manipulating India’s freeness and all-inclusiveness to keep Kashmir and its denizens in constant turmoil to get pleasure from other’s pain. They are doing same to Baluchistanis since partition and the Kashmiries of Pakistan held area are extremely unhappy and are in totters due to this policy of Pakistan.
Its Pakistan's fault not Indians....Pakistan should stop sending terrorists to India ...which is not happening at all....that is why Kashmiris suffering around there...
Malala should advise Pakistan government first not to involve with our domestic problems....
It is good for Kashmiris if they stay with India as far as their security and economic developments are concerned...
True that Malala has suffered beyond our imagination and came out of it bravely. But that doesn't make her an expert in everything.
Dear Malala, Can you please talk about the inhumanity and heartbreak in Pakistan-occupied Balochistan?
Malala Request you to please stay peaceful and stay happy and not say things that don't fit into ur vocab pls.
I didn't really used to like her but now my respect for her has gone up a lot.
Do you live in delusional world..what should paramilitary forces do if someone is breaking law and order of any country
Lets hope this time her voice will be heard as she has won Noble Prize for PEACE. Lets wish that India will keep Human Life above her EGO and will look Kashmir with HUMAN eye before there is no solution left
Dear Malala, Surely New Delhi government and Kashmiri people need to work together. Your concern is respected.
India in committing a genocide in Kashmir by killing innocent people SC must take notice of this.
As much as I admire Malala, I hate to see her get into Politics and Indo-Pak disputes. There are enough noises being made, or have been made, to no end.
please advise the kids to stop pelting stones and focus on studies to snatch the opportunities from rapidly growing Indian economy.
Thank you Malala for raising your voice in our support.
Since you are an influential opinion maker, I hope the world listen to you and stop the perpetrator from committing these atrocities against us.
Malalaji, Welcome to politics.
Dear Malala we respect you. But it is not government of India or Pakistan decide the future of Kashmir. There are some third parties who really want disturbance or conflict in the valley.
Trolls across the border always loved everything Malala spoke about. I hope they do the same now and accept stark reality!
Thank You Malala, for your kind words and care about Kashmiris
She is a teenage girl with little understanding of the dynamics of terrorism inspite of being a victim of it herself. The valley has been infected by the terror virus with religion which drove away the natural inhabitants of Pandits from Kashmir being hounded from mosque sermons. Many got murdered and not so lucky to escape. No one thought of their rights, now a generation has spent the life as refugee. Neither India nor local Kashmir government or the world body cares to it. However Pakistan terror export looks working well, but it is always the civilian who pays the price.
