Youth stabbed to death by girlfriend's brother during Ganesha immersion

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 22: The Karnataka government, which has fixed Rs 200 as fine for not wearing masks and covering faces to contain coronavirus spread, has collected Rs 3.43 lakh from 15,000 people as fine from May 5 till date.

"From May 5, the government has collected Rs 3,43,000 by fining 1,715 citizens for nor wearing masks or covering their faces," the Bruhat Bengaluru Mahanagar Palike (BBMP) Commissioner said in a statement.

Here is a zone-wise chart showing fines that have been collected:

Meanwhile, Karnataka Medical Education Minister Dr K Sudhakar said the state has reached its target of scaling up to 10,000 tests per day by conducting 11,499 tests on Thursday. In Kalaburagi, where the first COVID-19 case was confirmed in the State, conducted over 1000 tests yesterday.

"By conducting 11,449 COVID-19 tests yesterday, we reached our target of scaling up to 10,000 tests per day Kalaburagi that saw the first COVID-19 case in the state conducted over 1000 tests yesterday," Sudhakar said.

As per the Union Health Ministry, Karnataka has 1,605 positive cases, of which 571 have been recovered and discharged and 41 have succumbed to the infection.

Bengaluru, Apr 11: Former prime minister H D Deve Gowda claimed the lockdown decision was taken in 'haste' without forethought because of which farmers and the working class were 'suffering' and suggested measures to mitigate the impact. The state government should have consulted experienced citizens, officials, progressive farmers, farmer organisations and wholesale traders about the pros and cons before lockdown, he said in a letter to Chief Minister B S Yediyurappa, while highlighting that 61 per cent of the state's population depended on agriculture.

Because of the "hasty decision taken without any preparations", farmers of the country and the state are facing financial distress," he said in the April 9 letter, a copy of which was released to media here on Friday. The JD(S) patriarch suggested taking up some measures, including ensuring no restrictions on agriculture activities, procurement of horticulture produce at a fair price, relaxing export curbs on it, to provide relief to farmers, agriculture labourers, and daily wage workers.

On Sunday, Gowda had said he has assured Prime Minister Narendra Modi of his support in the nation's battle against COVID-19 pandemic when the latter called him to discuss the situation. In his letter to the chief minister, Gowda said: "...the lockdown implemented to control the spread of coronavirus has led our farmers into despair and put their lives into a burning fire.

This lockdown looks like a decision taken at haste without proper thinking and forethought for our farmers, agriculture labourers, and daily wage workers." He said the lockdown decision was taken after remaining 'quite' for about two months since the first corona infection was reported in the country on January 30. Among the suggestions made by the former prime minister include, procurement of horticulture produce at a fair price like in the case of milk from villages by the government through related organisations like Karnataka Horticulture Federation, HOPCOMS among others.

As horticulture produce was perishable, there should be no restriction on its procurement, transportation and marketing; all processing related activities of horticulture produce should be given relaxation from the lockdown, he said. Gowda also called for relaxation on exports for horticulture produce and its processed items. There should be no restriction on agriculture activities; a national grid has to be set up for marketing of horticulture produce, he said.

If such measures were not taken up immediately, the government will have to pay compensation to farmers for losses. Lack of remedial measures would lead to a shortage of supply, leading to rebellion from the people and may result in farmers' suicides and bringing about a situation that might be more grave than coroanvirus, he said.
