Threat call to rape victim’s kin: Kalladka Bhat’s arrest imminent?

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, May 30: Bengaluru City civic body Bruhat Bengaluru Mahanagara Palike (BBMP) has slapped a fine of Rs 50,000 on the food delivery startup Swiggy for irresponsible disposal of waste, an official said on Friday.

Randeep said a penalty of Rs 50,000 was imposed on Swiggy Kitchen at Katriguppe in the city for the violation.

"The incident with respect to waste segregation has been brought to our notice and happened at one of our kitchens in Bengaluru," confirmed a Swiggy spokesperson to IANS without revealing the exact details.

"While we investigate and rectify the root cause of the matter, we are reinforcing necessary awareness on the best practices to be followed amongst our teams and partner network to ensure complete compliance with waste management," the spokesperson added.

Swiggy has been penalised earlier as well for its irresponsible disposal of waste.

Recently, the BBMP’s solid waste management department has also fined an apartment complex Rs 15,000 for not segregating waste into dry, wet and reject categories.

Bengaluru, Jan 22: Chief minister BS Yediyurappa has urged the business community to focus on industries that are farmers and job-oriented and promised that his government would provide all the assistance it can in setting up these industries.

“My government will go the extra mile to facilitate industries that help farmers and provide jobs for youths,” Yediyurappa said during a meeting with several investors and entrepreneurs on the first day of the World Economic Forum, which brings global industry players and government representatives face- to-face, in Davos, Switzerland, on Tuesday.

The chief minister met representatives of 2000 Watt Smart Cities Association, which is represented by sustainability professionals of Nuesch Development, a Swiss Company, and ReNew Power. Both made presentations of their projects to the state delegation.

Yediyurappa appeared impressed by the 2000 Watt’s food processing clusters (development of modern infrastructure and common facilities) projects in rural areas. While presenting their concept, company representatives said they are willing to invest in food clusters, which can provide a better remunerative price for farm produce.

“We will provide all assistance and scientific farming techniques to grow healthy food and market them with added value to the produce,” said Andreas Binkert, scientist and academician, 2000 Watts.
