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.

Rasheed Bhai......... No individual is above the Nation. Personal attitudes will not damage the whole NATION and its CONSTITUTION. But a Political Party as a whole can make a difference to the NATION. Being a citizen of INDIA, just evaluate the Nation under BJP rule and CONGRESS rule you will get your ANSWER. Thank God.... your family is safe and secure, but think about those families who were the victims of BJP workers. The intolerance in last 4 years has gone from bad to worse. For God's sake, please keep your difference away especially for this State election and for upcoming General Election in Year 2019. All the best to all the Kannadigas and lets give another chance to CONGRESS to keep the injurious political party BJP much far away.
i think muslims should vote for Ashraf . attitudes of U.T is dangerous than bjp , he is selfish , his last five years attitudes shows he may sell entire community for his personel gains... such candidates should be defeated ....
improve ullal means..... he had not done anytihng to his own place then how we can trust him that he will develop karnataka/India........ i am not anti congress dear. but those who did not work for the welfare of the society should not win this election.... anyone maybe...... staying as loyal, honest, visiting funeral is not that he is good MLA or Minister.......
Abbu , what is your thinking brother, to improve ullal, you will vote against congress, really sad with your thinking , thing about India and people of Bharat , if you divide vote against the situation will be same , vote congress to get good results
use common sense please dont vote any muslims indipendent candidate, vote only congress
Some selfish and jealous people are trying to misguide the community. Instead of supporting and guiding the community to the unity, they try to divide just because of their selfish motives. Community should be very vigilant and aware of what is happening. While all secular forces trying hard to stop this Communal party, this kind of selfish people are trying to divide. They harm the community indirectly. Its better not to give an opportunity to our enemy rather than harming our own community. So be aware of this kind of selfish people. Its very easy for all political parties to be communal but secular parties are struggling. Instead of supporting secular parties, these selfish people trying to divide the votes. Very bad. Need to reject him outright.
Under the current state of affairs, we need to think about the whole KARNATAKA STATE and our great nation "INDIA". This JD(S) candidate is BJP's agent and they are not bother about our STATE & NATION. Even though if he win election this time, I can challenge he will never improve ULLAL. He will just fill his pocket and share few penny to BJP. Let all the Kannadigas be SMART and vote for CONGRESS - because the current situation in INDIA had forced all the MUSLIMS to vote only CONGRESS. We all should think that its CONGRESS V/S BJP only. No other parties should exists at this moment of time. Lets build a very strong and smart INDIA.
better vote all muslims for ashraf ... then how there will be vote divide..... UT khadar has not done anything to improve his place ullal
Good news for BJP
If you vote for Ashraf it is like voting for BJP. Do you want Modi and Amit Shah to win?
Be smart and don't vote for Ashraf
