Vistara's Bhubaneswar-bound plane hit by bird, all passengers safe

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.

Mumbai, Feb 26: Targetting Shiv Sena's silence over the recent controversial remark by AIMIM leader Waris Pathan, former Maharashtra Chief Minister Devendra Fadnavis on Tuesday said the Uddhav Thackeray-led party might be "wearing bangles" but the BJP was not and knew how to retaliate in the same manner.

"Shiv Sena might be wearing bangles but we are not. If someone says something then he will be given an answer in the same way. BJP has this much power," said Fadnavis while launching a scathing attack on ruling-Shiv Sena in Maharashtra for not taking strict action against Pathan.

Fadnavis was addressing protestors at Azad Maidan where BJP launched a protest against Maharashtra government over issues related to farmers and women.

On February 20, while addressing an anti-CAA rally, at Kalaburagi in Karnataka, Pathan had said, "time has now come for us to unite and achieve freedom. Remember we are 15 crore but can dominate over 100 crores."

"They tell us that we have kept our women in the front - only the lionesses have come out and you are already sweating. You can understand what would happen if all of us come together," he had said.

Facing flak over his remarks Pathan later took back his words and had said he had not targeted any community but had spoken against members of some organisations.

"If any of my words have hurt someone, I take them back as I am a true Indian," Pathan said at a press conference here.

The AIMIM leader said that he was being portrayed as being anti-Indian and anti-Hindu for the past couple of days.

"I want to say that my earlier statement was basically against people who are members of organisations like RSS, BJP, Bajrang Dal, etc. These 100 are those people who want to divide this beautiful nation," he added.
