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.

Here every one had a mistake. No one not ready to take their responsibility. So we no need to blame any one. The only one solution to stop the accident the government would install radar to every 5KM gap on each corner of the raod with camera (as it is in Saudi Arabia) with maximum speed of 40K.M. per hour. If they crosses this speed they will be penalty of Rs.200/- minimum. If this is done definitely accident will slow down soon and every rider will be safe. But government will cost more once.
Think this traffic department to install and fix the device in every corner of the road.
Road Accident is a serious issue. Daily hundreds killed because of it in India. But unfortunately nobody ( both govt and public) doesn't take this matter seriously..
why we should have a car which has speed of more than 80km per hour. Better late than never...
Oh Gov't.., do something for the sake of innocents life which you can.....

Motor bike is not at all good for mangalore roads....it is a kind of death trap...traffic is increasing day by day...no space for small vehicles to move around...at the same time big truck entering from nowhere...overall this kind of accidents are invited every now and then...so tragic...we need to ban motor bikes...most of young boys and couples are getting killed...so sad...
Inna lillahi vainna ilaihi rajihoon, O Allah forgive them and make good here after to them
