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.

If india gives him same punishment then assume that india is developed, in india criminals are given more respect than the victims.
Insane person. why dont you give him similar punishment....
Leave Bihar Campaign :)
Is controlling criminals important or fighting against Modi important? Nitish and KC Tyagi, please tell us
Shameless act from a political goonda. BTW had it been a BJP politician's son, CD would have had BJP in the headline. No I am not condoning the act if it was a BJP politician's son involved, I am just talking about how biased this channel is.
if the leader in the SUV was a BJP leader, your headline would have screamed the word BJP. Bajrangi RSS etc!
That politician's son is going to be get caught and will soon be released without facing any punishment.
that's how it happens in India!!!
in case of BJP politician, headline would have been ' BJP politician shoots 19 year old boy'. Since crime is committed by a non BJP politician, it only says politician in hearing.
This how the journalists manipulate the news.
Biharis Deserves... who voted corrupt Goonda Rajya
CM Nithish Kumar is in Kerala, he want the Kerala to be made same like Bihar.
Nitish Kumar is busy trying to cobble up a coalition in his desperate attempt to become the PM of this country. Meanwhile, the state is ruled by Lalu and his sons. So the jungle raj continues in Bihar.
its time to make bihar, up, wb ,delhi and kerala as independent nations. kick all these aholes from rest of india, let them solve their civility issue themselves.

THERE IS TOTAL JUNGLE RAJ PREVAILING IN BIHAR SINCE LAST 25 YEARS DURING RJD- JD(U) MISRULE. NITISH KUMAR IS RUNNING GOVT WITH HELP OF CORRUPT MEDIAS WHO ARE GETTING HUGE MONEY I.E. HUNDREDS OF CRORES PER ANNUM FROM JD(U) GOVT FOR FLASHING ROSY PICTURE OF CORRUPT AND WORST NITISH GOVT. LALOO HAS RETURNED REIGN OF TERROR IN STATE WHERE HIS COMMUNITY IS INDULGED IN MASS ANTI-NATIONAL ACTIVITIES LIKE NAXALISM, MURDERS, DACOITIES, KIDNAPPING ETC.
