A day before Red brigade’s ‘harmony rally’, Mangaluru streets turn Saffron

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, Feb 27: The Centre has adopted Prime Minister Narendra Modi's mantra of "Make in India', for India and the world" to build strong defence and security infrastructure in the country, said Defence Minister Rajnath Singh after inaugurating the new Light Combat Helicopter Production Hangar at Helicopter Division in Hindustan Aeronautics Limited (HAL) Complex here on Thursday.

According to an official statement, the Defence Minister said in the last five years, India has made significant progress towards manufacturing military equipment indigenously under the 'Make in India' initiative.

Stressing that the defence industry plays a major role in the economic development of the country, Singh lauded the significant contribution of organisations like HAL.

Highlighting the Rs 35,000 crore exports target set for the coming years, he expressed confidence that HAL, through its various platforms, will contribute significantly to achieve this milestone.

According to the statement, Rajnath Singh commended HAL for being the backbone of the Indian Air Force and meeting the requirements of the Armed Forces.

"The HAL has excelled both in operations and finance in the last five years. It has achieved operational clearance on seven platforms, including Light Combat Aircraft and Light Combat Helicopter, and overhauled platforms like Hawk and SU 30 MKI," he said.

He also appreciated that HAL had a turnover of Rs 19,705 crore till March 2019 and it gave shareholders a healthy dividend of 198 per cent.

HAL also apprised the Defence Minister on the progress of the new design and development programme of indigenous Indian Multi-Role Helicopter (IMRH), the statement informed.

The full-scale mock-up was showcased to Rajnath Singh. The IMRH is proposed as a replacement to the existing medium-lift helicopters such as Mi17's, Kamovs and Seakings which will phase out in the next eight to ten years.

LCH is a 5.5-tonne class combat helicopter designed and developed by HAL. It is powered by two Shakti engines and inherits many technical features of the Advanced Light Helicopter. LCH has the distinction of being the first attack helicopter to land in Forward Bases at Siachen, 4,700 mts above sea level with 500kg load.
