Jarkiholi will quit Congress, he has sympathy towards Opposition: Poojary

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, Apr 18: Private unaided schools in the state that were demanding fees from parents in the name of online classes and taking online admissions will face action under Section 3 of the Epidemic Diseases Act 1897, the Karnataka government said.

The Department of Public Instructions has warned school management of action against such educational institutes if they violate the rules. Following complaints from several parents and also from private school management associations, Minister for Primary and Secondary Education S Suresh Kumar discussed the issue with officials from the department during a recent meeting and directed them to initiate action against such academies.

In a guideline issued on Saturday, the department said, "Schools can conduct online classes. But are not permitted to collect the fee from parents until further orders from the department."

Suhaana shuddered with fear as she heard violent banging on her door on Sunday. The atmosphere was charged with communal tension after thousands of ruthless goons supporting contentious Citizens Amendment Act (CAA) launched a bloody onslaught against Muslims in the capital of India.

The family consists of Suhaana (name changed), her partially paralysed husband and two daughters. They are the only Muslim family in Madhuban mohalla of North Ghonda locality in north-east Delhi.

Hearts pounded louder than pounding of the door. Then the banging stopped and noises of men talking loudly came.

"I peeped out from a small window near the kitchen and saw our neighbours standing outside our entrance and arguing with 10-15 unknown people," Suhaana said.

It was the first day of the communal violence, worst in the decades, that fanned out to the entire north-east Delhi over the next three days and claimed at least 42 lives, left over 200 injured and properties worth crores destroyed. The death toll is feared to go up.

Later in the night Suhaana's family moved to one of their Hindu neighbour's house. There are about 30 Hindu households in the mohalla who kept vigil as the atmosphere deteriorated.

The next day, the violence escalated. The neighbours decided to shift Suhaana 's family to Gautampuri for their safety.

Suhaana recounted, "Our neighbours assured us that they are with us but as things were deteriorating, they said they wouldn't be able to protect us if a big mob of hundreds came. They advised us to move to the nearby Gautampuri locality and come back only after things become normal."

Rajkumar Bharadwaj brought the family to Gautampuri in the early hours on February 25.

Anil Gupta, 49, said, "It was tough to rescue them. We were asked by the rioters as to why we were saving the Muslims. But we had to, it is the people of my country who are suffering. It cannot be Hindus or Muslims."

Rajkumar Bharadwaj said, "Their youngest clung to me throughout. After I brought them here at Gautampuri, I felt good. Situation till then was not okay."

On Saturday, some semblance of normalcy returned to parts of north-east Delhi with some people opening their shops amid heavy police presence.

Meanwhile, the morbid sight outside GTB Hospital's mortuary, agonising groans in the hospital wards burnt down houses and shops remind Suhaana and others what they have been spared of.
