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.

Thiruvananthapuram, Apr 14: Amid Covid-19 lockdown,

Keralites celebrated a low key "Vishu" ,the Malayalam new year, on Tuesday, hoping that days of plenty, prosperity and peace will return.

People woke up in the early hours to see the auspicious "Vishu kani", symbolising hope, promise and fine prospects they wish to have in the year ahead.

The ritual comprises arranging on platters auspicious articles like seasonal fruits, vegetables, flower, gold and clothes which together form the first sight when the family members wake up on the Vishu day.

Normally, Keralites dressed in their traditional attire throng temples across the state.

However, this year due to the lockdown restrictions, temple visits were given a go by.

The famed Sri Krishna temple at Guruvayur and the Lord Ayyappa shrine at Sabarimala witnesses heavy rush of devotees during the vishu day.

But pilgrims were not allowed inside and only temple officials and security personnel were present for the"Vishu kani".

Rehaman, a small time trader, said very few people have come out for vishu purchases due to the restricitons.

It is fine as it is for a good cause, while Radha, a young woman said she could not celebrate the festival.

"We have no money, no job. With whatever little we have, we are celebrating the festival", she said.

87-year-old Vilasini Nambiar, a retired college professor, said vishu has visited the state during a most bewildering time.

"It should however remind us that every mountain must have its valley, desert its oasis, every storm cloud its rainbow, every night its day.

We are prepared to believe that we will overcome this misfortune", she said.

President Ram Nath Kovind, Prime Minister, Narendra Modi, Home minister, Amit Shah, Kerala Governor, Arif Mohammed Khan and Chief Minister, Pinarayi Vijayan, were among those who greeted people on the occasion of Vishu.

Udupi, Feb 16: Nine people were killed after a private bus collided with a large roadside boulder in Udupi district in Karnataka on Saturday, the police said. The accident took place on Saturday evening, at around 5.45 pm, on the Mulnur Ghat at Abbas Kattingeri in Mala village, while the bus was on its way to Mangaluru from Sringeri, reported the news channel.

The bus, which was reportedly carrying around 35 passengers, was trying to manoeuvre a turn while travelling on a ghat road when the driver allegedly lost control of the vehicle. The vehicle hit a massive boulder and the impact caused seven people to die on the spot. Two others passed away while they were on the way to the hospital.

The deceased passengers have been identified as Radha Ravi, Yogendra, Preetham Gowda, Basavaraju, Angana, Sharul and Ranjitha. The cleaner of the bus was also killed in the accident.

According to reports, the passengers in the bus were mostly in their early 20s and were employees of Vital Records Private Limited near JCK Industrial Park. Century Vital Records is a data security company which works in the Hebbal Industrial Mysuru. The group was visiting Udupi, Hornadu and Kudremukh.

While some of the injured persons were rushed to Manipal hospital, others were taken to the Karkala city government hospital, police said.

The police have said that rash and negligent driving by the driver is likely to have caused the accident. A case has been registered at the Karkala Rural Police Station, the police said.

Last month, three persons were killed and four others were injured after a fatal collision between a van and a bus near Bengaluru. Both the vehicles caught fire after the impact, but while passengers of the bus, travelling from Bengaluru to Shivamogga, managed to escape, the three passengers who were trapped in the van could not escape and were charred to death.
