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.

Your agenda in all election is " We will build Ram Mandir" if we elected to assembly. Now Central is with BJP hand, UP is with BJP hand then what is the issue? Why again and again saying we will build Ram Mandir - Ram Mandir every now and then. Road is free and why dont you take steps to build the temple and finish the issue?
Dear Non Muslim brothers and sisters, believe it or not - These so called politicians will never build Ram Mandir or whatsoever. This is the main Muddah for their election campain. Actually we the voters are fool and fighting each other (Hindu & Muslim), killing , looting innocents etc etc. - Finally who will benefit? These politicians and who is the looser - WE
Dear All - Please think about the development of our state, country and cast your valuable vote to the right candidate who may contribute to the development of our state/country. In this era Mandir-Masjid is not the issue - Issue is development, education, job, food etc etc.
The problem is BALATKARI JANWAR PATRY (BJP), Modi and Amit shah style of running the government on Hitler style has already filled the gandu rashtra people with poison in their brains to send Muslims out of India. This is the real problem. Gandus want their gandu rashtra at any cost now. Arab Muslims ruled India for 900 years and enriched the country with coffee, silk etc. Then British came and looted the country. Then these BJP and RSS are gifted with the divide and rule formula from British. They are now just following the same old formula to eat up whatever is left in the country. All this making hindu rashtra etc is a drama.
Comparing to Japan and other countries India is quite behind, because their aim is development, whereas our aim is Mandir/Masjid and religion. If India continues the same theory, India will never develop. These politicians are taking India on wrong direction.
Tippu is dead , shivaji also is dead. Why not worry about poor people like us who are still alive? We have enough masjid to pray , Allah will accept our prayers from any masjid, plz dont worry about that. Kindly finish the ram mandir as soon as possible. After all this done, kindly focus on jobs, roads, farmers, water, food, social services etc. i hope this is very simple english so u and your like minded friends can understand.
Thanks
