Scientists confirm smell and taste loss as early signs of COVID-19

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.

Shivamogga, Jan 2: A large number of farmers who wanted to stage a demonstration against Prime Minister Narendra Modi protesting the non-implementation of the 'Swaminathan Report' were detained at Bengaluru, Tumakuru and Shivamogga, police said on Thursday.

According to police, the detentions have taken place in certain parts of Tumakuru, near Bengaluru as well as in Shivamogga.

As part of his two-day visit to Karnataka, Modi is scheduled to visit Tumakuru on Thursday to pay his obeisance to the departed seer of Siddaganga Math Shivakumara Swamiji and meet the present pontiff Siddalinga Mahaswamiji.

Later, he would address a mega public meeting where he will give away the Krishi Karman awards.

In the evening he will reach Bengaluru to visit the DRDO facility to dedicate five DRDO Young Scientists Laboratories to the nation.

Pressing implementation of the Swaminathan Report, which recommends a holistic national policy, the farmers under the leadership of Kodihalli Chandrashekar had planned to stage a demonstration at Tumakuru.

Before they could leave for Tumakuru, the police detained them.

According to Chandrashekar, the farmers have been arrested at Nelamangala, Herohalli near Magadi, Kunigal and Koratagere in Tumakuru district and Shivamogga.

Speaking to PTI, Chandrashekar said the BJP has betrayed farmers by not implementing the Swaminathan report.

"The BJP could implement all the agenda such as abrogation of Article 370, paving way for Ram Temple in Ayodhya and various other poll promises but it ignored its promise of implementing the Swaminathan report," the farmer leader said.

Chandrashekar also said he has been detained at a ground on Magadi Road along with two others while farmers who wanted to take part in the protest have been detained in different parts of the state.

Bengaluru, Jan 25: The local police will provide security for Sri Nijagunananda Swami and his Kittur Nishkal Mantapa Mutt following a letter containing a threat to his life that was received on Friday.

The letter, containing the names of 15 liberal thinkers and activists, was circulated widely on social media and shown on some Kannada TV channels. The letter is addressed to the seer, and it condemns his lectures where he speaks in favour of liberal values.

“The decision to eliminate you will be taken on January 21. You will be eliminated, along with 15 of your followers and people who think like you,” the letter said. 

Among those threatened are Nidumamidi Channammalla Swami, Jnyana Prakash Swami, the former Chief Minister H.D. Kumaraswamy, actors Prakash Raj and Chetan Kumar, writer Chandrashekar Patil, Brinda Karat of the CPI(M) and writer K.S. Bhagavan.

It is not the first time that the seer is getting such threats. Two years ago, Belagavi Police had provided security to the seer following threats to his life. Last year, he got a phone call from a person from Shivamogga district. But the seer did not bother to complain.

This time, the district police will seek a written complaint from the seer. “We will assess the threat perception and the security levels. Adequate security will be provided,” the police said.

The seer is now camping in Jewargi in Kalaburagi district. “We have intimated the Kalaburagi Superintendent of Police of the need for immediate security arrangements. We will take steps to provide adequate security to him once he arrives in Belagavi district,” Superintendent of Police Lakshman Nimbaragi said.
