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.

An Indian Haj subsidy that did not exist!
Thank you Prime Minister Modi for ending Haj subsidy that never existed.
I completely welcome this move making the announcement, minister Mukhtar Abbas Naqvi said: “We believe in empowerment without appeasement.”Naqvi did not elaborate what he meant by “appeasement” but for decades, Haj subsidy remained a whip in the hands of right-wing parties to attack political rivals. Bharatiya Janata Party to embarrass rivals by accusing them of “appeasing” Muslims by subsiding expenses involved in the pilgrimage to Makkah and Madina. Angered by this attack, several Muslims have been demanding an end to the subsidy.
However, it is important to understand what this subsidy was and whether Muslims actually benefitted from it. In 2016-17, the government budgeted Rs 4.5 billion subsidy for around 100,000 Muslims who performed Haj last year. Each pilgrim paid around Rs 220,000 (amount varies each year) for airfare; stay in Makkah and Madina and for miscellaneous expenses. This money is paid to government-managed Haj committees which then transfers this money to other agencies. In other words, each Muslim pays for his/her own Haj expenses.
A significant chunk of money paid by Muslims goes to India’s government-owned national carrier Air India which enjoys a virtual monopoly on Haj circuit. The airline picks up passengers from around a dozen cities and flies them to Jeddah. The Air India inflates India-Jeddah tickets during the Haj season. This so-called government subsidy is used to pay for tickets that are always higher than the prevailing airfare charged by other airlines. A breakdown would show that an Air India ticket to Jeddah would cost more than a trip to Los Angeles from India. Essentially, the government takes money from one pocket and puts it back in another. Muslim have always demanded global tenders for Haj flights and for providing accommodation in Makkah and Madina..
However, while Naqvi sought to take a high moral ground by claiming that his party appeases no section of the society, his own government spends billions of rupees on organizing Hindu pilgrimages every year
Naqvi saab, this is what you learnt in Madrasa? U r Back-Stabbing Muslims. There is no 1% quality of muslim in you. After joining BJP you have lost it. First learn humanity. Almighty will give answers for all problems you have created for others.
