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, Jan 6: Karnataka Chief Minister BS Yediyurappa on Sunday launched the ruling BJP's outreach campaign in favour of the Citizenship Amendment Act (CAA) in Bengaluru.

"The CAA came into being after its amendment bill was passed in Parliament during its winter session with the support of major political parties. It is meant to give shelter and protection to Hindu minorities facing persecution in Pakistan, Bangladesh and Afghanistan. It does not take away any rights of Indians," Yediyurappa told residents on a door-to-door campaign in the city.

Accusing the opposition Congress of misleading the people on the CAA and inciting its protesters to indulge in violence, the chief minister said the Act does not cause any problem to all sections of Indians.

"There is no question of taking away anyone's citizenship, including that of Muslims, as the Act only facilitates the return of the Hindus persecuted in the neighbouring countries in the sub-continent," he asserted.

State deputy chief minister H.C. Ashwath Narayana and party's Bengaluru Central Lok Sabha member P.C. Mohan accompanied the chief minister on his outreach programme in some residential and commercial areas of the city.

As part of the nationwide campaign in favour the CAA, the party's state unit president Nalin Kumar Kateel and the state's dozen cabinet ministers led the campaign in other cities across the southern state.

"An awareness campaign will be peacefully held daily till January 15 across the state to counter the protests against it by students and other people at the behest of the Congress and Left parties," Kateel told reporters at Mangaluru, 350km southwest of Bengaluru.

Kateel is a BJP Lok Sabha member from the state's Dakshina Kannada seat.

Besides contacting the people directly at their doorstep through the party's leaders, cadres and supporters, the BJP is reaching all sections of society through social media and by holding pro-CAA rallies in all the 30-district headquarters across the state over the next 10 days.

"About 300 leaders and cadres of the party have fanned out in cities and towns across the state to explain the provisions of the CAA to the people and clarify their doubts, as the protesters were misleading them with wrong information about it," reiterated Kateel.

The CAA came into being after the President enacted the a law to give citizenship rights to Hindus, Sikhs, Jains, Parsis and Christians who have been allegedly persecuted as minorities in Afghanistan, Bangladesh and Pakistan over the last seven decades.

"A deliberate misinformation campaign has been carried out against the CAA by vested interests, misguiding a section of college/university students, their faculty, activists and members of the minority community on its provisions so as to create unrest and trigger violence in the country," Ravikumar claimed.

The ruling party also held rallies and public meetings in major cities like Mysuru, Mangaluru, Hubballi, Belagavi, Bellary and Kalaburagi across the state and enlightened the people on the benefits of the CAA.

"As social media is all-pervasive with greater reach and better impact, we are also reaching about one crore people of all ages through Kannada, Hindi and English script, messages and audio/video clips in the state during the fortnight campaign," added Kateel.

New Delhi, Mar 4: Tech giant Intel has said one of its employees in Bengaluru has "potentially been exposed" to coronavirus and is currently under quarantine.

In India, we have implemented precautionary measures such as travel and event restrictions, visitor screenings at all our offices, increased frequency of office sanitisation, and work-from-home provisions," it said.

The virus outbreak, which has seen cases being registered across the world including South Korea, Iran, Italy and Japan, has had a significant impact on businesses across industries.

Microblogging platform Twitter has asked its employees to work from home while other tech giants like Tata Consultancy Services and HCL Technologies instructed staff to avoid non-essential travel as IT firms put in place measures to safeguard workers against the deadly coronavirus.

The coronavirus outbreak claimed over 3,000 lives globally, and fresh cases being reported in India.

The government has stepped up its efforts to detect and check the virus outbreak whose epicentre was in China.
