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, Feb 4: The CBI has booked Karnataka cadre senior IPS officers Hemant Nimbalkar and Ajay Hilori along with eight others in connection with Rs 4,000-crore I-Monetary Advisory (IMA) scam in which gullible investors were allegedly cheated in the name of Islamic banking, officials said on Tuesday.

The move came after the CBI received an approval from the Karnataka government to proceed with investigation into alleged role of 1998-batch IPS officer Nimbalkar and 2008-batch IPS officer Hilori, they said.

Along with the two officers, the agency has also named the company IMA, its founder Mansoor Khan and others in the case.

The CBI had approached the state government seeking permission to proceed against the two officers who are in senior positions in the Karnataka Police and allegedly helped IMA founder Masoor Khan, they said.

Mangaluru, May 31: The bus services by private operators in Dakshina Kannada and Udupi Districts will begin from tomorrow (June 1) with 15 per cent hike in the fares, Canara Bus Owners Association president Rajavarma Ballal said on Sunday.

In a statement issued here, he said that the members of the Association have appealed for a 3-month tax break. ''We have received tax breaks for 2 months and have demanded for an additional month again,'' he added.

He said that the government has agreed to a 15 per cent hike in bus fares. All the passes issued already will be converted into cash cards and no discounts will be available till the end of the COVID-19 crisis.

An added attraction in private buses will be the option of paying travel fares through smart cards.

According to Dakshina Kannada Bus Operators Association president Dilraj Alva, 50 per cent of 325 private city buses will resume their services on Monday. It also meant that 50 per cent of buses will operate on the allotted routes.

The smart cards (or travel cards called Chalo Card) will not be introduced on all routes at a time. They will be introduced in a phased manner covering all routes from Monday.
