Bengaluru: AirAsia staff accused of sexually harassing woman passenger

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, May 8: After continuous pressure on Union government from Karnataka NRI Forum- UAE, the first special flight carrying 180 Kannadigas who stranded at UAE due to Covid-19 pandemic will fly from Dubai to Mangaluru on May 14.

The special flight will take off from Dubai at 4.10 p.m. UAE time to reach Mangaluru at 9.10 pm IST on May 14. Earlier it was reported that the flight will operate on May 12. However, sources of Mangaluru International Airport and Air India today confirmed that first flight will be on May 14.

The state government has directed Dakshina Kannada and Udupi districts authority to quarantine all passengers once they reach.  

All Kannadigas will be given permission to travel back home only after they test negative in Covid test at Dubai airport.

In fact, Karnataka was missing in the list of states to receive special flights when Ministry of External Affairs arranged them to bring stranded Indians at UAE. Special flights were arranged only to Kerala and Tamil Nadu people stranded at UAE in the first stage.

Thanks to Karnataka NRI Forum of UAE which opened helpline (https://uaekannadahelpline.club) to seek assistance to Kannadigas, nearly 2000 Kannadigas have registered for assistance in which 127 pregnant women, 27 senior citizens, 700 people who have lost jobs aftermath of coronavirus sought assistance from NRI forum.

After providing food and shelter to Kannadigas who lost jobs at UAE since March 2020, NRI forum put pressure on both state and Centre to arrange special flights to send them to home. 

The NRI Forum has approached Indian Consulate at UAE and chief minister BS Yediyurappa to evacuate Kannadigas, but got no response. Following this, Karnataka NRI Forum President Praveen Shetty approached Union Minister for Chemicals and Fertilizers DV Sadananda Gowda for help. Gowda immediately responded the call and he spoke to MEE to arrange special flight for Kannadigas as well.

Indian government has promised to arrange special flight to Mangaluru or Bengaluru by next week to bring Kannadigas.

Comparing to other Indian States, Karnataka has the highest number of its people working in UAE. Around 1.25 lakhs Kannadigas are working in UAE in which majority are working classes. Due to Covid-19 pandemic thousands of workers have lost jobs, Mr. Shetty explained.

"Indian government had arranged special flights from US, UK, Singapur and other countries to bring back Indians, but excluded UAE in the list. Actually, lakhs of Indians are working in UAE as labourers and in odd jobs, the government should have given first priority to bring labourers rather rich one", he opined.

"BJP has 27 MPs from Karnataka. We continuously requested all BJP MPs and state government but none of them came to our help. Thanks to Mr Gowda for his timely intervention to bring stranded Kannadigas", Mr Shetty said.
