Swamy model lie exposed: Ministry says Priyanka, Karti have only one DIN

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.

Udupi, Jun 20: The wife and daughter of a 54-year-old man who succumbed to Covid-19, tested positive for the virus on Saturday.

Sources said that the family returned to Udupi on June 18 and the man died the same day while his wife and daughter tested positive today.

The man and his family had arrived at their house in Thekkatte on Thursday, June 18 afternoon. Later in the day, the man died. He was suffering from jaundice and had arrived from Mumbai in the state of illness.

New Delhi, Feb 1: The budget is a little more demanding of the non-resident Indian. Firstly, to be categorized a non-resident, an Indian now has to stay abroad for 240 days, against 182 previously. In other words, an Indian national, to claim the non-resident status, can’t stay in India for 120 days or more in a year.

“We've made changes in Income Tax Act where if an Indian citizen stays out of the country for more than 182 days, he becomes non-resident,” said Revenue Secy Ajay Bhushan Pandey. “Now in order to become non-resident, he has to stay out of the country for 240 days.”

The second rule is more deadly: a non-resident Indian, who is not taxed in the foreign country, will become taxable in India.

“If any Indian citizen is not a resident of any country in the world, he'll be deemed to be a resident of India and his worldwide income will be taxed,” said Pandey.

"It's a very big disadvantage for Indians residing overseas only to save on tax,"  said Dinesh Kanabar of Dhruva Advisors. He expects that many Indians stay abroad in countries, where the income tax is low or nil such as Dubai. Now they will be taxed in India if they are in the income tax bracket.

For Indians, finance minister Nirmala Sitharaman revised income tax rats and proposed new tax slabs.

The new income tax rates will, however, not allow exemptions under Section 80C. Home loan exemption, insurance exemptions, the standard deduction will also not stay under the regime.

"The new tax regime will be optional and the taxpayers will be given the choice to either remain in the old regime with exemptions and deductions or opt for the new reduced tax rate without those exemptions," Sitharaman said while unveiling Budget.
