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.

Riyadh, Apr 24: As many as eleven Indian nationals have died due to COVID-19 in Saudi Arabia.

"As per information available with the Embassy as of April 22, eleven Indian nationals (four in Madinah, three in Makkah, two in Jeddah, one in Riyadh and one in Dammam) have passed away due to COVID-19 in Saudi Arabia," the Embassy of India in Saudi Arabia said in a press release on Wednesday.

It urged the Indian community to remain calm and avoid spreading of rumours amid the COVID-19 crisis.

"The Embassy also reiterates the need for the community to remain calm and avoid spreading of rumours that may create panic. It is important that social media is not used to disseminate false messages and spread hatred along communal lines that can vitiate the atmosphere," the Embassy said.

"As stated by Prime Minister Narendra Modi, COVID-19 does not see race, religion, colour, caste, creed, language or borders before striking, and our response and conduct should attach primacy to unity and brotherhood," it said.

Moreover, several measures on the supply of food, medicines and other emergency assistance to Indians in need are being implemented across the Kingdom.

Earlier, Indian Ambassador to Saudi Arabia, Ausaf Sayeed on April 22 had interacted with Indian community volunteers from the smaller towns all across the Kingdom to discuss the impact of the COVID-19 situation, and evaluate the implementation of various measures to ensure the welfare of Indian nationals.

Dubai, Apr 14: Around 2,500 Indians have approached Indian missions in the United Arab Emirates (UAE) seeking help to be flown home during the ongoing coronavirus lockdown, top diplomats have said.

The Indian Embassy in Abu Dhabi and the Indian Consulate in Dubai together have received requests from "a little more than 1,000 individuals" while the latter has received an additional request from an employer who has laid-off around 1,000 Indian workers, reports Gulf News on Monday.

According to the Indian Ambassador to the UAE Pavan Kapoor, the missions have not been bombarded with mass requests from the people who wish to take an immediate flight home unlike widespread reports on social media.

Most of the individuals who have expressed their interest to return home are visitors and those who lost their jobs, he told Gulf News.

Consul General of India in Dubai, Vipul said his mission had received nearly 1000 requests via email and phone from people who want to return home.

"A majority of them are visit visa holders. On Sunday, we got information about another large group of around 1,000 Indian workers who have lost jobs. The employer has got in touch to know the options to send them back home as early as possible," he told Gulf News.

However, the diplomatic heads refuted unverified reports that claim tens of thousands of Indians were scrambling to fly home during the pandemic.

They added that the missions have been aiding hundreds of workers, who have been left in the lurch by their employers, with provisions.

The Indian government had said that flight services cannot be resumed during the lockdown period, which has now been extended till May 3.
