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.

Jan 14: A day after it moved the Supreme Court against the controversial Citizenship Amendment Act (CAA), the Kerala government on Tuesday said it would continue its fight against the legislation as it "destroys" the secularism and democracy in the country.

The CPI(M)-led government had on Monday moved the apex court challenging the CAA and sought to declare it as 'ultra vires' of the Constitution. State Industries Minister E P Jayarajan told reporters here that the state has moved the apex court and will explore all options to fight the Act.

"The state government will to go to any extent and continue its fight against CAA. This Act destroys democracy in the country. This will only help in implementing the RSS agenda, to drive the nation through a fascist regime, and destroying the secularism and democracy in the country. The RSS and the Sangh Parivar cannot implement this law just by using muscle power," Jayarajan said.

Tourism Minister Kadakampally Surendran tweeted that the state became the first in the country to approach the top court against the Act. "Kerala government files lawsuit against the unconstitutional CAA. Kerala becomes the first state in the country to go to the Supreme Court against CAA.

"Kerala leads the way," he said in the tweet. In a suit filed in the apex court, the Kerala government has sought to declare that the CAA 2019 was "violative" of Article 14 (Equality before law), 21 (Protection of life and personal liberty) and 25 (Freedom of conscience and free profession, practice, and propagation of religion) of the Constitution.

It also claimed that the law was violative of the basic principle of secularism enshrined in it. The state Assembly had on December 31, 2019, passed a unanimous resolution against the CAA and became the first state to do it.
