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 11: Members of Karnataka Congress women's wing staged a protest in Shivamogga on Friday against the rise in onion prices and domestic LPG (liquefied petroleum gas) cylinders.

As a mark of protest, the demonstrators wore garlands made of onions, drew rangoli on the road and cooked food with firewood. The protestors also carried posters comparing the price of cylinders in Congress and BJP-led government in the Centre.

The price of non-subsidised LPG was hiked by Rs 19 per cylinder from January 1, 2020.

New Delhi, Jul 22: Sir Philip Barton visited Bengaluru on Tuesday in the first of the series of virtual regional visits as the UK's new High Commissioner and called Chief Minister BS Yeddyurappa, business leaders, and startup community to pitch for new momentum in the already strong UK-Karnataka relationship.

During his virtual call, High Commissioner Barton got a 'real' taste of Bengaluru through a traditional Masala Dosa delivered to his residence in Delhi along with authentic south Indian filter coffee, which he relished over a chat with historian and commentator Ramachandra Guha. They discussed the unique UK-India "living bridge" across culture and cuisine, history and heritage, and sports and science.

Both Yeddyurappa and the British envoy restated their commitment to working together on the immediate challenges of Covid-19 and beyond.

Barton subsequently 'traveled' to Electronics City, where he met with a range of key business leaders to discuss deepening the UK-India tech partnership and opportunities for global investors in the UK.

Barton also met with a group of entrepreneurs, business founders and innovators, who were part of the first GoGlobal UK cohort to explore the dynamic UK market considered one of the best ecosystems for startups in the world. 

They had earlier attended a week-long boot-camp in London and Manchester in December 2019 that helped them bolster their business skills, build links with UK's thriving digital sector, and paved the way for future partnerships.

"I am delighted to make my first regional virtual visit to Bengaluru, the technology hub of India. My visit comes at a difficult time for everyone. So it is also a time when the excellent collaboration between the UK and Karnataka across technology and healthcare could not be important," Barton said.

"Making the most of those close links, and drawing on the great energy, innovation and entrepreneurship that Karnataka is famous for, will be central to ensuring we all recover from Covid-19 stronger than ever," he added.
