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.

Bengaluru, May 29: Seven out of ten (72 per cent) workers in Karnataka reported having lost their employment during the COVID-19-induced lockdown, according to findings of a survey by Azim Premji University, in collaboration with ten civil society organisations.

The university said in a statement it conducted "a detailed" phone survey of 5,000 workers across 12 states in the country, to gauge the impact of the COVID-19 lockdown on employment, livelihoods, and access to government relief schemes.

The survey covered self-employed, casual, and regular wage and salaried workers and it released the findings for Karnataka on Thursday.

Seventy-six per cent of urban workers and 66 per cent of rural workers lost their employment, the survey findings said.

For non-agricultural self-employed workers and wage workers, who were still employed, average weekly earnings fell by two-third.

More than four in ten salaried workers (44 per cent) saw either a reduction in their salary or received no salary during the lockdown.

Six out of ten households reported that they did not have enough money to buy even a weeks worth of essential items, according to the survey.

Eight out ten households reported a reduction in food intake, while less than three in ten vulnerable households (27 per cent) in urban Karnataka received any form of cash transfer from the government, it said.

In summary, the disruption in the Karnatakas economy and labour markets is enormous. Livelihoods have been devastated at unprecedented levels during the lockdown.

The recovery from this could be slow and very painful, the statement said.

As a response to the findings of this survey, the team which has conducted the survey suggested a universalisation of the PDS to expand its reach and implementation of expanded rations for at least the next six months.

It suggested cash transfers equal to at least Rs.7000 per month for two months, and proactive steps like expansion of MGNREGA, introduction of urban employment guarantee, and investment in universal basic services, among others.

Bengaluru, Mar 14: The Rashtriya Swayamsevak Sangh (RSS) on Saturday suspended its proposed Akil Bharatiya Pratinidhi Sabha (ABPS) meeting scheduled to be held in the outskirts of the city, in the wake of the outbreak of Coronavirus in the state.

'In view of the seriousness of the pandemic COVID-19 and in the light of instructions and advisories thereof issues by the Union and the state governments, the Akil Bharatiya Pratinidhi Sabha meeting scheduled in Bengaluru has been suspended', Sarakaryavah Suresh Joshi tweeted.

All Swayamsevaks should cooperate with the administrations to create awareness among the public and to face this successfully, he said.

It may be recalled that Karnataka State Government had ordered shut down of pubs, malls, theatres, and ban mass gatherings over the Coronavirus scare, on Friday.
