Won’t ascend Paryaya Peetha for 6th time; will guild my heir if I were alive: Pejawar seer

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, Jul 10: The Karnataka cabinet gave its approval for "The Karnataka Contingency Fund (Amendment) Bill, 2020" to enhance the contingency fund limit to Rs 500 crore in the wake of the COVID-19 pandemic.

This will be an ordinance making one time enhancement in the limit as the government needs money to make payments immediately, Law and Parliamentary Affairs Minister JC Madhuswamy told reporters after a cabinet meeting.

Under the contingency fund, the government had room to spend up to Rs 80 crore without budget provision.

"...but this time due to COVID-19 as we had to give money to some sections that were in distress like barbers, flower and vegetable growers, taxi drivers, among others, we have decided to increase the limit to Rs 500 crore," Mr Madhuswamy said.

"As assembly was not in session and as we had to make payments to those in distress immediately, this decision has been taken," he added.

The cabinet today ratified the administrative approval given to carry out civil and electrical works to install medical gas pipeline with high flow oxygen system at district hospitals, taluk and community health centres coming under Health and Family welfare department in view of COVID-19.

The minister said about Rs 207 crore is being approved for this purpose.

It also ratified procurement of medical equipment and furniture for public healthcare institutions of the health and family welfare department worth Rs 81.99 crore.

According to the minister, the cabinet has decided to bring in an amendment to section 9 of the Lokayukta act, which mandates that the preliminary inquiry contemplated by Lokayukta or Upalokayuta should be completed in 90 days and charge sheeting should be completed within six months.

Noting that at the Agricultural Produce Market Committee (APMC) cess was being collected, he said as the government had brought in an amendment to the APMC act, there was demand to reduce the market cess. "So we have reduced it from 1.5 per cent to one per cent."

Approval has also been given by the cabinet to bring Karnataka Vidyuth Kharkane (KAVIKA) and Mysore Electrical Industries (MEI), which are presently under the control of Commerce and Industries department, under administrative control of the energy department.

Other decisions taken by the cabibinet include deployment and implementation of "e-procurement 2.0" project on PPP at a cost of Rs 184.37 crore and ratification of the action taken to issue orders on March 24 to release interest free loan of Rs 2,500 crore to ESCOMs for payment of outstanding power purchase dues to generating companies.

The cabinet also gave administrative approval for setting up of an Indian Institute of Information technology at Raichur.

"Under this, we are committed to provide Rs 44.8 crore in four years for infrastructure," the minister added.
