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.

Mangaluru, June 21: The first ever repatriation flight from Saudi Arabia’s Dammam Karnataka’s Mangaluru under Vande Bharat Mission (VBM) today brought home around 165 stranded passengers. 

The IndiGo flight took off from Dammam International Airport at 11 a.m. (Saudi time) and landed at Mangaluru International Airport at 6:30 p.m.

The stranded passengers included pregnant women, senior citizens and those who are in need of emergency medical treatment are on board.

The passengers were screened at the Airport before being despatched for institutional quarantine in special buses. 

Even though a few charter flights arranged by a couple of NRI entrepreneurs have already repatriated hundreds of stranded people from Dammam to Mangaluru, the government of India had not operated any repatriation flight under VBM on this sector so far. 

Saudi Kannadigas Humanity Forum (SKHF), an NGO which came into existence to help the stranded Kannadigas in Saudi Arabia during covid-19 lockdown had been successful in persuading the government of India operate a flight on Dammam-Mangaluru sector under VBM. 

SKHF has also set up an online portal for those who were in need of emergency repatriation. In today’s flight around 100 passengers have obtained seats through SKHF.

Mangaluru, Jun 26: In a gut-wrenching incident, a pack of stray dogs attacked a herd of barking deer, also known as Indian muntjac at Dr Shivaram Karanth Biological Park at Pilikula on the outskirts of the city last night.

Dhama H Jayaprakash Bhandary, director of the biological park said: “Due to heavy rains a tree was uprooted damaging the compound wall of the park one day ago. Last night pack of stray dogs entered the park and attacked the barking deer. When the incident came to light, 10 barking deer had lost their lives and many others were injured.”

He said that five years ago they had rescued four barking deer that bred and multiplied to 40. “We had planned to release some of the barking deer to jungle and retain around a dozen in the park. Last night’s incident has shocked us,” he said, adding that the injured barking deer are being treated.
