Vistara's Bhubaneswar-bound plane hit by bird, all passengers safe

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.

Udupi, May 28: The India Meteorologic Department (IMD) on Thursday warned fishermen in coastal belt of Karnataka against venturing out into the deep sea between May 31 and June 4.

The Department stated that depression is expected to occur in the south-eastern part of Arabian Sea and the nearby areas and it would be dangerous for the fishermen of Karnataka, Kerala and Lakshadweep to go out towards the deep sea.

The Department officials said that they would provide information on development in weather conditions. In the backdrop of the current weather forecast, however, the fishermen in the western coastline were advised against venturing into the sea.

Indore, Jul 24: A woman who sells fruits on a cart and who lashed out at municipal officials here has done PhD in Materials Science. Her siblings too are well educated and sell fruits as they did not find jobs.

Dr Raisa Ansari, who lives at Bakery Street in Pardeshipura with her family said she wanted to be a scientist but did not get a job anywhere.

Speaking to media persons, Raisa said, "I have done PhD in Materials Science and wanted to be a scientist but did not get job anywhere. I sell fruit here but the municipal officials are bothering us. We are being forced to move from here to there like cattle. Our religion may be the reason why we are not getting jobs but we are proud to be Indian. I am still looking for a job."

Dr Raisa's mother Ayesha Ansari said she herself is not educated, but has four children of whom three girls and one boy studied a lot but no one got job.

Raisa and Shahjahan Bi wanted an educated boy, but they were not able to find a suitable match because of their complexion and sometimes they rejected the proposal because of dowry, so both are single. Two of my grandchildren are studying biology. They will become doctors," said Ayesha.

Meanwhile, people in the neighbourhood lauded the family's abilities. They said theirs was an educated family had to sell fruits as they did not get jobs.
