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.

Idiot YOGESH, don't just say what ever you get into your mind, I work for RSS & MRM, You should know the fact that Ismail nelyamajalu used to visit tirupathi lord balaji for darshan with his family once or twice a year, he also used to conduct jathara(festival) at a temple in sullia, DK, every year. He was a very kind human being more than a muslim & a politician.
A very good husband, father, brother and a friend, I personally know him since 2013.

Death is not a disaster simply a passing from this world onto the next. It should make us reflect and ponder about the purpose of the life and what will become of us after death. Innah ilahi wa inna ilaihi rajihoon Deep condolence insha Allah grant him forgiveness and higher in heavens. Ameen
I have conducted a survey of Friday murders in coastal Karnataka. Especially immediately after or before Muslims special prayers. 99% of such murders are committed by Muslims only.
So Yogesh is making a confession that BJP is behind this murder ?
Shocking incident, he was really a prominent leader of congress. anyways rest in peace.
May his soul rest in peace
whoever made this brutal crime must be punish them in the like same. seriously a inhuman act.
