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.

Sure he will pay for such barbaric henious act, just a matter of wait and watch.
Retaliate kill him and supportng RSS leader in same manner.
Uncultured barbarian act...!! Culprit should be hanged in order to put end to these ruthless act.
Shourya diwas part 2 by VHP? India is becoming famous in negative sense day by day, all credit to right extremist hindu groups!
Give them more power, we will become next Taliban, Nazi!!!
That whole area of Indian subcontinent (India, Pakistan, Bangladesh, Sri Lanka etc) is still pretty much brutally primitive. Not only that they have not achieved much in materialistic standards in seven decades of independance but in terms of behavior also, the people on the ubcontinent have remained to be quite primitive !
RSS should be happy today, as one of their cadre has done them proud. RSS has made animals out of humans. This is what RSS wants in India. Great. Bharat Mata ki Ja
Love jihad is a very dangerous practice which is now spreading in whole of India. Though the murder of a lab on the name of love jihad in Rajasthan can not be justified but those responsible for this practice must be identified and sent in jail with exemplary punishment.
Check the original video. The cries of the poor helpless man are still haunting me. How can somebody be so ruthless? Comparing this scumbag to an animal is an insult to whole of animals. As lynching was a common phenomenon by the so-called fully tolerant, totally peace loving Hindus, I felt perhaps it should be the work of few uncivilized religious bigots. Now I wonder the difference between Hindus and the other peace loving religion. If Hindus have muscle power, money power, position and the required resources, they can be one of worst sects or an ideal competitor for the other peace loving religion in this world.
@Bhageeraha Bhaira,
What you said is applicable to all. Many so called "peace lovers" killed poor peopel.
Many Hindus got killed by muslim terrorists. Then no news.
Mr Kumar! Killing is not intolerance. This is terrorism. The word ‘Intolerance’ can be used if someone doesn’t tolerate the smell of your body.
Intolerance... Attack on muslims increasing
Shocking incident
