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.

The college was against the sharia simply, change the college why this college only. if done like this this kind of all colleges they learn lesson .
Their marriage halls we have issue their they cooking haram things & we also cooking hallal then we no problem, because this all our dignity .throw your dignity follow Quran & Sunnah and became original muslim
If clg rules are against democracy we hv to chnge clg rules not our rights.
When injustice becomes law be on the side of justice
thn islam is peace & beautiful bt the systems are against islam thn this islam also hv certain stratagy & thts thought by prophet (s.a)
Secular? If right to cover the head is not secular for you, then there are million christians/hindu women out there wearing head scarfs including former President Prathiba Patil. So, you mean to say that they all cannot have education in India?
Ughhhhh. Individual choice yes. But college has certain rules. You don't want to follow the rules, you don't join that particular college. Also, Islam is a very beautiful religion. Let's not make it all about the Hijab.
100% they are Indians as they are fighting for their rights which is guaranteed by INDIAN CONSTITUTION. Now could you pls chek your voter ID and of the Principal who made rules against the constitution which is legally termed as Anti-Indian rule.
How can this Principal wearing head scarf frame college laws which is against to the constitution of India. Why she is allowing her sibling nuns wearing Hijab like dress and head scarf attend classes in the same college? What is her hidden agenda? How can she justify her draconian dictat??
Someone must check the voter IDs of protesters to find out whether they are really Indians
Why do these bigots go to a secular college if they want Taliban rules?
At one side head of the institutions are wearing head scarf and allowing Christion nuns whose dress code includes head scarf to follow their tradition. On the other side they are objecting Muslim girls to wear head scarf which is similar as their scarf. May I call it as #hypocrisy
Please decent girls don’t go to that college.
Students all are equal in the college
