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 19: Karnataka Chief Minister B S Yediyurappa on Sunday said he has had detailed discussions with BJP National President Amit Shah on the cabinet expansion and that the exercise would be carried out after his return from Davos.

The Chief Minister told reporters before leaving for Davos to attend the World Economic Forum meet that he hoped his visit would help bring in large-scale investments to the state. "On cabinet expansion, I had detailed discussions for about half-an-hour (with Amit Shah on Saturday), got a good response... one or two days after I come from Davos, I will expand the cabinet. There are no stumbling blocks for it", Yediyurappa said.

He also rubbished media reports about a lack of clarity on the Ministry expansion. "It is not right... there are no issues", he said.

Asked whether he would travel to Delhi to meet Shah after returning from Davos, Yediyurappa merely said, "It is natural for me to meet Amit Shah." According to the Chief Minister's tour programme, he will be back in the city on January 24.

Yediyurappa, along with Union ministers Piyush Goyal and Mansukh Mandaviya, as well as Chief Ministers Amarinder Singh of Punjab and Kamal Nath of Madhya Pradesh, are among those expected to join over 100 Indian CEOs at Davos in the coming days for the WEF's 50th annual meeting.

Stating that he was leaving on a four day trip for Davos with an aim to bring investments to the state, he said interactions have been fixed with 38 industrialists and investors. "There is a large possibility of investments coming to the state from meetings during the WEF meet. I will assure industrialists and investors that the government will give all necessary facilities within our limits and also clear all the doubts that they have," the Chief Minister said. He said employment opportunities in Karnataka would increase due to all these efforts.

Claiming that the economic situation in Karnataka was stable despite the global economic slowdown, he said the state was also organising the Global Investors Meet in November to attract industries and create employment opportunities.

The delegation led by Yediyurappa includes Industries Minister Jagadish Shettar, Chief Secretary T M Vijaya Bhaskar and top officials of the state government. The Chief Minister, who was anxiously waiting for the high command's nod to expand his ministry amid intense lobbying by the aspirants, was keen on getting approval for it from Shah, but was asked to visit Delhi after returning from Davos, party sources said.

They also said that with J P Nadda all set to take over as BJP National President, he would have final discussions with Yediyurappa on the Ministry expansion exercise. S R Vishwanath, Political Secretary to the Chief Minister too said that Yediyurappa would go to Delhi after his return from Davos and immediately expand the Ministry.

He said the Chief Minister has been asked to hold discussions with Nadda, who is currently BJPs National Working President and finalise things.

As the Chief Minister has already made it clear that 11 of the disqualified JDS-Congress MLAs who got re-elected in the bypolls on BJP tickets will be made ministers, lobbying has been on in the party for the remaining ministerial berths. Currently, there are 18 Ministers, including the Chief Minister in the cabinet that has a sanctioned strength of 34.

However, with some reports that the high command may not be keen on making all the 11 re-elected legislators, whom Yediyurappa has given assurance, as Ministers, it remains to be seen how things turn out. Cabinet expansion will not be an easy task for the Chief Minister as he will have to strike a balance by accommodating the victorious disqualified legislators as promised and also make a place for old guards, upset at being "neglected" in the first round of the induction exercise.

He also has to give adequate representation to various castes and regions in his cabinet and also deal with the allocation of key portfolios. Also, disqualified legislators who lost on a BJP ticket during the bypolls like A H Vishwanath (Hunsur) openly expressing their ministerial aspirations has added to the Chief Minister's worry.

Bengaluru, Feb 17: Union Finance Minister Nirmala Sitharaman on Monday assured that the Centre is committed to stand by its promise of providing Rs 18,600 crore Bengaluru suburban Rail project.

Addressing a press conference after a post-budget interactive session with the representatives of the various trade bodies, industry leaders and others here, she said that the union cabinet has already given its clearance for the long-pending project.

Informing that the central government will have 20 per cent of its capital share in the project followed by another 20 per cent share from the state government, she said "beside this, the union government will stand for a sovereign guarantee for the rest of the 60 percent share, which can be raised through loans from external agencies".
