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 17: Karnataka Medical Education Minister K Sudhakar held a meeting through video conference on Thursday with private and government establishments involved in testing and treatment of COVID-19 in the state.

A total of 51,422 cases including 19,729 recoveries and 1,032 deaths were reported in the state till yesterday.

On the same day, K Sudhakar also paid a surprise visit to the Bengaluru's CV Raman Hospital and urged the administration to follow COVID-19 guidelines properly. He also took stock of the hospital's preparedness to fight the deadly virus.

"Surprise visits will continue. I will be in touch with every lab and get the right number of tests done on a daily basis," the minister said while speaking to the media.

He also urged the people who have recovered from coronavirus to donate their plasma to save other lives, adding that donors will receive a reward of Rs 5,000 as a token of appreciation.

Bengaluru, Mar 28: The Karnataka government on Saturday said that the state run Indira Canteens would provide food packets free of cost to the poor and needy in the wake of the lockdown, the government said here on Saturday.

The canteens would operate in three schedules -from 7:30 AM to 10 AM, 12:30 PM to 3 PM and 7:30 PM to 9 PM, the government said in a public announcement

During the scheduled hours, street side vendors, labourers and poor would be provided food free of cost.

After the cabinet meeting on Friday, Chief Minister B S Yediyurappa had said food packets would be provided to the poor and needy with the help of some organisations through the Canteens and had sought the help of everyone in this regard.

The State-sponsored, subsidised 'Indira Canteens' as of now serves breakfast at Rs five and lunch and dinner at Rs 10.

The government asked people availing the facility to maintain cleanliness at the canteen and staff who serve food to compulsorily use masks and hand gloves.

It also said soaps and sanitizers should be made available at the canteens.

The government also asked people to maintain a minimum distance of one metre while standing in queue and take all precautionary measures.

Earlier, a day after announcing that food would be provided free of cost through the canteens for daily wagers, Yediyurappa on March 24 had said it has been decided that the canteens will not be opened, after realizing that it was leading to crowding, which drew criticism.
