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.

May be because of infected Gomoothra
JINU...
How did U come into being... QURAN speaks on our CREATOR who created all that exits... and It asks us to use our intellectual which ALLAH has given us. I request you to PONDER on what it says...
Please read the QURAN once & research what it says... Dont just sit idle and make your own asumption. living a life of unaware... about the CREATOR will be worse than animals..
May God help them all! They are all innocents.
Devaru kotta prasada beda annbardu...! May be some sanghi poojaris' wanted to cut down cost for his selfishness. Probe needed.
May the victims recover soon!
I agree, believing blindly doesnt make sense... But God has given intellectual to human being and he created us to worship him alone... Y dont we use our intellectual to know who is worthy of Worship rather than worshiping idols and animals...
Even in vedas, it say that those who worship such things are in DARKNESS...So to come out of such DARKNESS ... the idols or man made god worshipers should try to know who is GOD and Y we need IDOLs to reach GOD...
God says he is near to any caller, there is no need keep any life less object and ask with it... in other sense U can call him by saying \O the one who put soul in me, who gave life to me ...Guide me.No doubt his help will come to those who trust him... Try it."
