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.

After all these sufferings,it pains a section of us,common peole still support demonetisation !
What was supposed to be a surgical strike against tax cheats and counterfeit currency became an attack on a large informal economy that ran almost entirely on cash. The hardships caused by a shortage of new legal tender, and the rush to deposit old 500 and 1,000 rupee ($15.40) notes in bank accounts before the Dec. 31 deadline, took a heavy toll. More than 100 people died in bank and ATM queues, although it's impossible to confirm if the deaths from heart failure or exhaustion were directly a result of demonetization.
I Will donate one rope to hang him.
@Truth Teller - I share your views 100%
Honestly, i am not sure what is there to like about Congress! Besides all the scams running to several thousand crores and losing face in the international scene (thanks to Kalmadi) they have played religion & caste politics for decades for vote bank ruining the country. For the first time after independence perhaps there is some move towards honesty, improving infrastructure, education and cleanliness. Why some continue to hate Modi is just beyond me if you truly love this country. Rahul is bad news for India unless they find someone else who can be like Modi - hardworking & with a vision to change.
Honesty is incompatible with the amassing of a large fortune - Mahatma Gandhi
Modiji is the true and honest man after Gandhi
Demonetization in India was a war against dishonesty and it is a movement against corruption.This exercise has brought an awareness to the people not to make wealth dishonestly.Majority of the people wanted honest system in India and supported the Government's initiative on demonetization.
I am a hardworking sincere person. I earn for a living and to support my family, because of demonetization me and my family suffered without any cause. This man freezes our transactions to a minimum of 2000 and what not. Who was he to do it, By law it is not permissible unless a person is held guilty by law agencies.
Because of one man 100 innocent died standing in queue. How come once company made 160000 times profit during demonetization, Where is the black money, what happened to panama papers. These statistics have to shown after demonetization. Even now they are misleading crores of people with data not important to Aam Admi.
Dinesh Gundu will soon be under police custody
Nobel prize winner praised Modi for demonetisation and digital India and later he confessed he told wrong after knowing that Modi banned old 100&500 notes and implemented 2000 rupees notes..
I can say Modi is the best intelligent person in the world. And he should get business man of the year award.
Because,
1. Modi made huge benefit to Paytm (paytm ceo didnt do this much profit for his company)
2. Modi made profit to the private agency which made/maintaning aadhar things.
3. Modi made profit to Jio
4. Modi made profit to big companies by implementing demonetisation and GST (same time it affected badly on small scale retailer shop)
