Raheem Uchil terms BSY govt ‘pro-Beary’ as it sanctions Rs 6-cr for Beary Bhavan

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.

Bengaluru, Mar 18: Karnataka Congress President DK Shivakumar on Wednesday met the Director-General of Police in Bengaluru and demanded police protection for Madhya Pradesh Congress MLAs and the removal of BJP workers from the hotel in Bengaluru, where the legislators are currently lodged.

"The (Madhya Pradesh) legislators have come here and have requested police protection, that is all. Let the police give them protection, our candidate (Digvijaya Singh) has come, let him meet the legislators. Why are BJP workers protecting them? We know that they are under threat and hence we need to vacate them (BJP workers)," Shivakumar told reporters here after the meeting.

"We will give protection to our men and that is why we are telling them they cannot stop us. They should be in a free and fair position. I have communicated to DGP that BJP needs to vacate," he added.

Earlier today, Congress' Rajya Sabha candidate from Madhya Pradesh and former chief minister Digvijaya Singh was placed under preventive arrest after he sat on a dharna near Ramada Hotel here, allegedly for not being allowed by police to meet the 21 Congress rebel MLAs lodged in a hotel.

"I am a Rajya Sabha candidate from Madhya Pradesh, voting is scheduled for March 26. My MLAs have been kept here, they want to speak to me, their phones have been snatched, the police is not letting me speak to them saying there is a security threat to MLAs," Singh told reporters.

Singh who sat on the dharna with a face mask on said: "We were expecting them to come back, but when we saw they're being held back, messages came from their families...I personally spoke to five MLAs, they said they're captive, phones snatched away, there is Police in front of every room. They're being followed 24/7," Singh said.

The development comes amid the political crisis in Madhya Pradesh after the exit of Jyotiraditya Scindia from the Congress party.

Scindia's departure was followed by 22 Congress MLAs resigning from the party as well as from the state legislative Assembly.

The resignation of these MLAs has left the Kamal Nath government below the majority mark.
