Ignoring threats by communal forces, IAS topper Tina Dabi weds her Muslim friend

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.

Mangaluru, Jan 1: Led by two local MLAs belonging to Bharatiya Janata Party, dozens of people today forcibly stopped toll fee collection at Talapady toll gate on the outskirts of the city allowing vehicles plying between Karnataka and Kerala on the national highway 66 to travel without paying any fee for some time.

Mangaluru City South MLA D Vedavyasa Kamath and Mangaluru City North MLA Y Bharat Shetty, who led the workers, said that the Navayuga Udupi Tollway Pvt. Ltd. (NUTPL), the concessionaire of the about 90-km-long highway widening project between Talapady and Kundapura in Karnataka, had failed to complete the project since over a decade.

The service roads and two flyovers under the project remained uncompleted. Hence motorists were facing a hardship. Notwithstanding Nalin Kumar Kateel, Dakshina Kannada MP, arranging ₹56 crore loan to the NUTPL through Axis Bank to complete the prominent Pumpwell flyover in the city, the company had failed to complete it.

The MLAs said that they stopped the toll collection as a symbolic protest to bring pressure on the company to complete the project within this month.

The BJP workers who gathered near the toll gate around 7.30 a.m. forcibly removed the barricades and made the vehicles ply without paying the fee. The workers of the company managing the toll booth did not resist.

The BJP workers said that vehicles would ply without paying toll till about 6 p.m. If the company resumed the collection during the day on Wednesday, the party workers would again forcibly stop it on Thursday, they said.

Shivaprasad Rai, in-charge of toll collection of the company at Talapady, Hejmady and Sasthana on the same highway told The Hindu that the NUTPL collected about ₹7 lakh as toll fee daily at Talapady from over 12,000 vehicles. The loss on Wednesday could be about ₹4 lakh.

The project is being implemented under build, operate and transfer basis.
