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.

PFI is the first kind of organization which is doing community work in all the walks of life.
and providing the helping hands to all the Indian community doing marvelous job.
this is the first organization fighting against corrupt and injustice following the principle of our father of nation mahatma Gandhi’s.
the corrupt and injustice people in the society not ready to accept their policy and trying to stop the voices of justice to the society.
I wish PFI and its sub organizations will continue to support to the society and keep the good work so that people are with you.
Wah what a joke.
RSS is blamming others as terrorists.
Constitutionof RSS is a terrorism. Stupid Hegevar and Savarkar are the heroes of illiterate stupid community.
The whole intelligent community including European Uniion and US openly declared.
This is the sure end and downfall of RSS, which will never come-up again. You woke-up of peace lovers.
Thank you.
You people are never fit to run even a small village and how come thinking of ruling a big country.
RSS is the most active and first ever terrorist organisation in India and it should be banned first. There is no proof of terrorist activities by SDPI and PFI. BJP is afraid of these organisations as they give tought resistance to BJP and this is the reason why its planning to ban these organisations. BJP is doing propoganda only. Real thread for peace + harmoney in India by sanghis. We should ban them first.
