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.

who ever dead we should respect the soul bcoz..it belong to GOD almighty...
if he done good he will get heaven if he do idol worshipping then ( ) .....
Idol worshipping is the biggest sin ever done by mankind, you cant insult GOD by placing some stone, many hands and tunge out and animal figur.

Enlighting from the verses of the Quran :
Quran 29:57 - Every soul will taste death, then it is to Us that you will be returned.
Quran 3:26 - Say, "O Allah, Owner of Sovereignty, You give sovereignty to whom You will and You take sovereignty away from whom You will. You honor whom You will and You humble whom You will. In Your hand is [all] good. Indeed, You are over all things competent.
Quran 3:27 - You cause the night to enter the day, and You cause the day to enter the night; and You bring the living out of the dead, and You bring the dead out of the living. And You give provision to whom You will without account."
Quran 3:30 - The Day every soul will find what it has done of good present [before it] and what it has done of evil, it will wish that between itself and that [evil] was a great distance. And Allah warns you of Himself, and Allah is Kind to [His] servants."
