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.

This attack on Karnataka by BJP. Why did not they raid houses of BJP leaders who have become rich after BJP came to power. Reddy brothers are roaming freely and had lavesh wedding of their daughter. IT department are sleeping
Timing is good!!. Each one repeats same in cycle and then they may stop doing corruption. But Indian political population is a strange one and may start bribing each other! Congress also did all kind of tactics! Timing of investigation of corrupt DMK - daughter!
How can congress explain recovery of 10.5 crores cash from the minister's residence?Is it not embarrassing for congress leaders who called the raid witch - hunt?
What does BJP say about corruption of their own leaders. How many raids were given on the corrupt leaders of BJP. There are not hundred but thousand cases of corruption of BJP leaders. Recently in Chhatishgarh, one minister Brijmohan Aggarwal has encroached the government land. A few days ago Chief of Kerala BJP was caught for taking bribe of Rs 6 crores. After demonetization maximum black money was recovered from these BJP leaders. Before demonetization, dubious land deals were executed with their black money as they know fully that demonetization was to be declared by their party.. Black money was recovered from the BJP leader in Punjab as well from Madhya Pradesh leader. Who is funding Amit Shah who is roaming using chartered planes from one place t0 another place. What were the sources of funds during elections either for the Centre or for the states. Admitted Congress is corrupt but BJP is the most corrupt party in India.Wherefrom they got 15 crores to purchase MLAs.
All corrupt politicians are the feathers of the same bird. All are corrupt whether in the ruling party or in the opposition. Some of them are pro industrial and getting unaccountable money to be spent on their rival parties to let down. If any leader is corrupt and facing trial in the court, they either try to purchase the sitting judges or transfer them on the name of promotion. These tactics have been used by Modi Government in Gujarat to have clean chits in Godhara riots.The enquiry commission was appointed to enquire about who were behind the killings of innocent Sikhs, one Mishra was purchased by the Congress party and he was taken in Rajya Sabha.These commission heads are corrupt and working as per directions of the ruling party. How one can get justice. In India justice is denied to poor, downtrodden and minorities. These political parties have cleverly expert to change the facts into lies. They are expert to purchase and threaten others who are disagreed with them
How can there be black money? Demonetisation was supposed to eradicate it.
He's questioning the time, he's not questioning all that money that's been
seized!
