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.

Dubai, May 3: Over 150,000 Indians in the UAE, who wish to return home amid the coronavirus lockdown, have applied through the online registration process to the Indian missions here, according to media reports.

The Indian missions in the country last week opened online registration for the expatriates who wish to fly back home after getting stuck in the country amidst the lockdown due to the coronavirus pandemic.

As of 6 pm on Saturday, we received more than 150,000 registrations, Consul General of India in Dubai Vipul told the Gulf News on Saturday.

A quarter of them want to return to their homeland after losing their jobs, he said.

According to a report in the Khaleej Times on Sunday, about 40 per cent of the applicants who have registered are blue-collared workers and 20 per cent are working professionals.

"Roughly 20 per cent have suffered job losses and about 55 per cent of the total applicants are from Kerala," Neeraj Aggarwal, Consul, Press, Information, Culture was quoted as saying in the report.

Aggarwal said that the figures would change as they are expecting registrations from workers from other states, including Telangana, Uttar Pradesh, and Bihar.

About 10 per cent of the applicants are visit and tourist visa holders who got stranded here due to the ongoing lockdown in India.

India extended the ongoing lockdown by two weeks from May 4 to contain the spread of the coronavirus that has affected nearly 40,000 people in the country.

Aggarwal said that a small number of the applications constitute those from pregnant women and other medical cases.

Since the online registration process was launched, the Consulate's website crashed several times due to the heavy rush of applicants wishing to register to fly back home.

The site has been working fine now though it took a lot of time for it to stabilise in the initial phase due to the heavy traffic, the counsel general said.

He said that the missions here have not yet received any information from the Indian government about the mode of transport of the stranded citizens, the prices of the tickets or how the COVID-19 test results of applicants would be assessed for their journey.

There are high-level discussions going on regarding these things, he said in the report.

Meanwhile, Norka (The Non Resident Keralites Affairs) said it has received a total of 398,000 applications from Keralites across the globe who wish to return home.

"Of which, the highest numbers are from the UAE. At least 175,423 applicants have signed up from the UAE," Norka said in an official statement on Saturday.

It also received 54,305 registrations from Saudi Arabia, 2,437 from the UK, 2,255 from the US, and 1,958 from Ukraine from those who wish to return to India, the Khaleej Times reported.

The coronavirus has infected 13,599 people and claimed 119 lives in the UAE, the Ministry of Health and Prevention said on Saturday.
