Watch row: Cong high command not happy with CM's explanation

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.

New Delhi, June 27: The Prime Minister Narendra Modi-led union government of India is not ready to stop all imports from aggressive China in spite of mount calls to boycott Chinese products in India.

The Centre is reportedly considering to stop only non-essential imports from the neighbouring country.

However, the Inward shipment in sectors such as automobiles, pharmaceuticals, certain electronics and others will continue until a domestic alternative is found.

“India will gradually move towards import substitution. It will not happen overnight. In the meantime, attention has to be paid on production and job creation. We cannot throttle our industry. There are certain absolutely essential imports. Needless to say, those will keep going,” official sources said.

Sources said that both the government and the industry are in the process of identifying products that can be domestically manufactured in the medium term. There are certain chemicals, automotive components, handicrafts, cosmetics, agriculture items and certain consumer electronics, which can be manufactured domestically in the short to medium term. The government is doing all it can to raise the capacity of domestic industries.

However, there are certain other imports in the automobile and the pharmaceutical sectors which cannot be done away within the short to medium term. Their domestic production at the moment may not be that cost-effective.

The six-crore strong traders’ body CAIT has been at the forefront of such a demand and has launched a campaign to celebrate Indian Diwali this year with a total absence of Chinese goods.

“Ease of doing business, capital availability at lower rates and globally competitive logistics and energy costs are some of the prerequisites that the government should look into to ensure the growth of the domestic auto component industry,” according to Automotive Component Manufacturers Association of India (ACMA) Director General Vinnie Mehta.

Maruti Suzuki Chairman R C Bhargava said, “People who are boycotting Chinese goods have to remember that in some cases it may lead to their being asked to pay more for the same product."

Meanwhile, domestic rating agency Acuite Ratings & Research has analysed the current import portfolio from China and found 40 sub-sectors have the potential to lower their import dependency on China. These sectors contribute to $33.6 billion worth of imports from China and about 25% of these imports can be substituted by local manufacturing without any significant additional investments.

Bengaluru, April 2: At least three people have been arrested by police in connection with the attack on ASHA worker Krishnaveni in Bengaluru's Byatarayanapura area.

Earlier in the day, Bengaluru Police Commissioner Bhaskar Rao said that an investigation was initiated into the incident in which ASHA workers were attacked.

"I have appointed Pulikeshi Nagar ACP, Tabarak Fathima, to investigate the matter. A case will be registered and action will be taken. ASHA workers will be protected by the police to carry out their functions," Rao told ANI here.

Earlier, Karnataka Deputy Chief Minister CN Ashwath Narayan visited one of the ASHA workers who was allegedly attacked by unidentified miscreants and termed the incident as "completely demoralising" for the workers.

ASHA workers, who were deployed to spread awareness about coronavirus and identify suspected cases, were allegedly attacked by a group of locals in Byatarayanapura here on Wednesday.

The workers said that the locals did not allow them to work and around 100 people gathered at the spot and harassed them.

This comes as the country is under a 21-day lockdown to prevent the spread of coronavirus.
