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.

9/11 caused more Americans to embrace Islam.
The same thing happens here, more Truth Loving people start researching the speech of Zakir Naik and will easily embracing Islam.
Indians are more free and intelligent in deciding.
Unfortunately the RSS lead govt can detain him under pretext of so called all allegation, even without proof.
We have some blind law where innocent people become easy prey.
Such law is made to target the people who talks truth against the corrupt leaders.
Laks...Karkala.....
Every one knows you hypocrites are experts in fabricating proofs and give clean chit to criminals ...... Indians can eat indian cow meat in Gulf BUT not in India.... Go to Google and find out the names of Indians in the list of TOP CRIMINALS of the world ....Hypocrite ....
Laks, Karkala
From your frustrated comments i can understand that you are so far from the reality. Not a single proof can indian govt can show against Dr.Zakir naik. Even nobody can have the guts to have debate with zakir naik. so will wait and watch.
Laks, Zakir Naik did not trouble anyone...when he was preaching around everyone lived very happily here in India....He conveyed peace message to everyone...
Dear Altaf,
Dont teach us what to ban...Our present government have enough proof to put him behind the bar...and your lawyer is der to protect him..so leave it to court
Sitting in Doha its easy for you to comment
Basically it is not the matter of scare. In the recent years we have noticed that the Muslims are targeted & put behind bars without any evidence.
Later it is proved that the RSS goons are involved in the terror activity across the country. But they are not booked in any case.
These types of double standard Judicial System makes the Muslims to be away for certain period. I hope very soon Br. Zakir Naik we get justice & start spreading the peace message.
Mr. Zakir Naik's Preaching, Knowledge and popularity not gone well with sick minds, they cannot counter him through dialogue; obviously misuse of power is the solution!!!
Laks, Karkala
If you really wish to see that everyone in india should leave happily then you have to think about banning RSS and sangh parivar. Zakir naik never done anything so that hindus and muslim divide. He always tried to unite all religion. I think you have not listened to any of his speeches. My sincere request with you is to first listen his all complete speeches. Then come to conclusion.
Please watch the below videos. It is available in Youtube
1.Similarities between Hinduism and Islam
2.Similarities between Islam and Christianity
3.Does God Exits
4.Is terrorism a muslim monopoly
Hope after watching the above you can change your thinking from negative to positive .
Over all this is a political game with the backing of rss communal group.
Started to target peace loving INDIANS and Mr. ZN is on top of their list.
There is many more to come from religious leader to business man;social worker; leading person etc.
Instead of 5 years high court need to ban for life time... so that everyone can leave happily in India
ZN is scared..he will not come back to india.. if he was Innocent he could have came back long back ago...
