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 9: The Karnataka government may not extend the daily working hours from 8 to 12, with Labour Minister A Shivaram Hebbar saying on Saturday that the move would neither benefit the industries nor workers.

Hebbar said that the proposal has not been discussed and it may come for final deliberations next week. He also noted that some States have already extended the working hours. More than extending working hours, there should be employment to be given. If there are no jobs what can be done by extending working hours? If it is done (working hours extended to 12 hours), it would neither benefit workers nor industries. Let's see what happens, he said.

Asked if the government was in favour of the extension, he said, "I don't think it will be ready for the (12 hour) proposal." Meanwhile, the Minister also said that their top priority now was to see that all MSMEs start operating again, salaries are paid to employees and there are no job losses for any reason. If industries don't reopen, how can workers get their employment? We should think in parallel, Hebbar said adding, the government was keeping the interests of both MSMEs and workers in mind.

He urged the Centre to offer a relief package to the MSME sector, saying it is facing very difficult times due to the adverse impact of the COVID-19-induced lockdown, and also noting its role in generating large-scale employment and feeding large industries.

The BJP-led government has done whatever within its limitations to help the MSMEs, he said. Earlier this week, the Chief Minister B S Yediyurappa announced that the monthly fixed charges of electricity bills of MSMEs would be waived for two months. MSMEs have suffered huge production losses due to the lockdown. It takes some time for them to revive, Yediyurappa had said. The Chief Minister had also said payment of fixed charges in the electricity bills of the large industries will be deferred without penalty and interest for a period of two months.

Bengaluru, June 22: BJP leader and Madikeri MLA Appachu Ranjan has urged the Karnataka Chief Minister B S Yediyurappa and Home Minister Basavaraj Bommai to drop cases against the saffron activists who had involved in attacks against cattle traders and transporters across the state.

In a letter addressed to the CM and the Home Minister, the MLA expressed his concern against the illegal transportation and slaughtering of cattle. Cow is considered to be holy in Hinduism. Butchering of cattle has been hurting the religious sentiments of people, he stated.

Ranjan stated that cases had been registered against 'Gau Rakshaks' or cow vigilantes who had fought against the illegal transportation of cattle.

“Filing cases against the protectors of cattle is condemnable. If the cases are not dropped, then there will be none to question the illegal cattle transporters,” he said adding that cases registered against various police stations against cow vigilantes must be dropped.
