Indrajit, who had threatened Gauri Lankesh, not cooperating in probe: SIT

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, Mar 19: To better enforce social distancing and prevent further spread of Covid-19, the Karnataka health and family welfare department on Wednesday said it will "stamp the back of the palm" of international passengers advised to be on home quarantine, along with the date they are allowed to get out of home. The stamping process began at 12am Thursday.

Pankaj Kumar Pandey, commissioner, health and family welfare, said: "It is noted that a few passengers under home quarantine are not following the instructions. Therefore, it has been decided to stamp the back of the palm of their left hand with a specially designed stamp which will indicate the last day of quarantine."

He said the special stamp will use an indelible ink and "airports in Karnataka have been instructed to follow this without fail". On average, about 3,000 people are arriving in Bengaluru on international flights every day.

The department said social distancing is the only known method of combating the spread of Covid-19 and added, "International passengers are segregated as symptomatic and asymptomatic."

High-risk flyers kept at mass quarantine unit

The symptomatic passengers (Group-A) are taken to designated hospitals; asymptomatic ones, depending on the port of origin, are taken to the quarantine centre or permitted to go on home quarantine.

At the mass quarantine centre, the asymptomatic passengers are divided into moderate-risk (Group-B) and high-risk (Group-C) categories.

“The high-risk passengers are kept at a mass quarantine centre for medical observation. The moderate-risk passengers are being sent for home quarantine where they need to spend 14 days,” the statement added.

Pandey said: “International passengers changing flights within the country cannot be stopped. Ideally, they should be stamped at the first port of entry when they arrive from a foreign country which is not happening.” He said this issue will be brought to the notice of the Directorate-General of Civil Aviation.

Bengaluru, Jan 10: State’s primary and secondary education minister, S Suresh Kumar on Friday asked the Department of Public Instruction to register a complaint in the cybercrime police station against the teacher who shared a video of a child mispronouncing a Kannada word.

The viral video shows the child from a government school incorrectly pronouncing the word 'Pakkelubu' (ribcage).

The minister observed, 'It is normal for children to pronounce words incorrectly and only repetitive practise will make them say it correctly. If a video of such a mistake is made and spread on the Internet the child will see it in future and be demoralised and might start hate learning. The person who made and posted this video has committed a grave crime.
