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 biggest weapon of RSS is spreading lies and hatred. Who can stop that N Bomb?
Oh this big mouth minister from Left, I being a person from Kerala really know truth. CPIM uses their offices and politcians house to store arms. CM Vijayan and this fellow wanted to have special darshan tickets in Sabarimala and when it was shot down.... all this stories
Raid all mosques, churches and temples and check for arms
Bamboo Sticks/ Lathis are not Weapons. Donot get Bogged down. They cannot use weapons to hurt. They just open their mouth and shout
Time for Hindus to take back Kerala and Kashmir.
Chief Minister should order police raids on these arm stores and recover the arms, and install CCTV cameras to monitor the activities round the clock. CM needs to substantiate his allegations with proof. I fully agree with his view that no religious ceremony should take place during any official function, it has no place in secular democracy. Our constitution gives every citizen right to practice religion of his or her choice freely but not at state level. State has no religion.
Here is a Minister for Temples Administration. He defines a temple as a centre for traditions and beliefs. Sorry Comrade , a temple is a place for worship of God. If it is only a place of tradition and faith, there is the danger of it being appropriated by the communist Party, which has both tradition and faith. No temple in Kerala will allow storing of weapons within, may be in its offices or quarters of staff. Is it a plan for the commies to violate the sanctity of the temples?
