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.

India ranked 77th on a sustainability index that takes into account per capita carbon emissions and ability of children in a nation to live healthy lives and secures 131st spot on a flourishing ranking that measures the best chance at survival and well-being for children, according to a UN-backed report.

The report was released on Wednesday by a commission of over 40 child and adolescent health experts from around the world. It was commissioned by the World Health Organization (WHO), UN Children's Fund (UNICEF) and The Lancet medical journal.

In the report assessing the capacity of 180 countries to ensure that their youngsters can survive and thrive, India ranks 77th on the Sustainability Index and 131 on the Flourishing Index, it said.

Flourishing is the geometric mean of Surviving and Thriving. For Surviving, the authors selected maternal survival, survival in children younger than 5 years old, suicide, access to maternal and child health services, basic hygiene and sanitation, and lack of extreme poverty.

For Thriving, the domains were educational achievement, growth and nutrition, reproductive freedom, and protection from violence.

Under the Sustainability Index, the authors noted that promoting today's national conditions for children to survive and thrive must not come at the cost of eroding future global conditions for children's ability to flourish.

The Sustainability Index ranks countries on excess carbon emissions compared with the 2030 target. This provides a convenient and available proxy for a country's contribution to sustainability in future.

The report noted that under realistic assumptions about possible trajectories towards sustainable greenhouse gas emissions, models predict that global carbon emissions need to be reduced from 39·7 giga­ tonnes to 22·8 gigatonnes per year by 2030 to maintain even a 66 per cent chance of keeping global warming below 1·5°C.

It said that the world's survival depended on children being able to flourish, but no country is doing enough to give them a sustainable future.

"No country in the world is currently providing the conditions we need to support every child to grow up and have a healthy future," said Anthony Costello, Professor of Global Health and Sustainability at University College London, one of the lead authors of the report.

"Especially, they're under immediate threat from climate change and from commercial marketing, which has grown hugely in the last decade," said Costello – former WHO Director of Mother, Child and Adolescent health.

Norway leads the table for survival, health, education and nutrition rates - followed by South Korea and the Netherlands. Central African Republic, Chad and Somalia come at the bottom.

However, when taking into account per capita CO2 emissions, these top countries trail behind, with Norway 156th, the Republic of Korea 166th and the Netherlands 160th.

Each of the three emits 210 per cent more CO2 per capita than their 2030 target, the data shows, while the US, Australia, and Saudi Arabia are among the 10 worst emitters. The lowest emitters are Burundi, Chad and Somalia.

According to the report, the only countries on track to beat CO2 emission per capita targets by 2030, while also performing fairly – within the top 70 – on child flourishing measures are: Albania, Armenia, Grenada, Jordan, Moldova, Sri Lanka, Tunisia, Uruguay and Vietnam.

"More than 2 billion people live in countries where development is hampered by humanitarian crises, conflicts, and natural disasters, problems increasingly linked with climate change," said Minister Awa Coll-Seck from Senegal, Co-Chair of the commission.

The report also highlights the distinct threat posed to children from harmful marketing.

Evidence suggests that children in some countries see as many as 30,000 advertisements on television alone in a single year, while youth exposure to vaping (e-cigarettes) advertisements increased by more than 250 per cent in the US over two years, reaching more than 24 million young people.

Studies in Australia, Canada, Mexico, New Zealand and the US – among many others – have shown that self-regulation has not hampered commercial ability to advertise to children.

Children's exposure to commercial marketing of junk food and sugary beverages is associated with purchase of unhealthy foods and overweight and obesity, linking predatory marketing to the alarming rise in childhood obesity, it said.

The number of obese children and adolescents increased from 11 million in 1975 to 124 million in 2016 – an 11-fold increase, with dire individual and societal costs, the report said.

To protect children, the authors call for a new global movement driven by and for children.

Specific recommendations include stopping CO2 emissions with the utmost urgency, to ensure children have a future on this planet; placing children and adolescents at the centre of global efforts to achieve sustainable development, the report said.

New policies and investment in all sectors to work towards child health and rights; incorporating children's voices into policy decisions and tightening national regulation of harmful commercial marketing, supported by a new Optional Protocol to the UN Convention on the Rights of the Child, it said.

Bengaluru, Jan 11: India’s second-biggest IT company, Infosys Ltd, said it found no evidence of financial misconduct by its executives following a investigation into whistleblower complaints.

Bengaluru-headquartered Infosys, which earlier on Friday raised its revenue forecasts due to upbeat demand from Western clients, said an audit committee report exonerated Chief Executive Officer Salil Parekh and Chief Financial Officer Nilanjan Roy of all allegations, including accusations that the duo prevented employees from presenting data on large deals.

“I’m very happy that CEO Salil Parekh and CFO Nilanjan Roy have emerged from this stronger,” Infosys Chairman Nandan Nilekani told reporters. “The last two years since Salil has been here the company has changed dramatically for the better.”

Parekh took over as Infosys CEO in January 2018, after his predecessor Vishal Sikka quit following a public row with the company’s founder executives amid whistleblower allegations of wrongdoing.

The company earlier said it expected revenue to grow between 10 per cent and 10.5 per cent on a constant currency basis in the year ending March 2020, compared with its previous forecast of between 9 per cent and 10 per cent.

“We continue to see momentum in the market and we have an extremely robust pipeline driven by segment leaders,” CEO Parekh told a news conference.

“With the strength of large deal wins and digital momentum, we were able to clearly see that we have support to raise our guidance.”
