Temperature data collected by wearable devices worn on the finger such as a ring can be reliably used to detect the onset of fevers, a leading symptom of both Covid-19 and the flu, say researchers. In a study, published in the journal Scientific Reports, more than 65,000 people wearing a ring manufactured by Finnish startup Oura, recorded temperature, heart rate, respiratory rate, and levels of activity.

The goal of the study is to develop an algorithm that can predict the onset of symptoms such as fever, cough, and fatigue, which are characteristic of Covid-19.

“With wearable devices that can measure temperature, we can begin to envision a public Covid early alert system,” said study author Benjamin Smarr from the University of California, San Diego in the US.

Wearables such as the Oura ring can collect temperature data continuously throughout the day and night, allowing researchers to measure people’s true temperature baselines and identify fever peaks more accurately.

“Temperature varies not only from person to person but also for the same person at different times of the day,” Smarr said. The study highlights the importance of collecting data continuously over long periods of time. Incidentally, the lack of continuous data is also why temperature spot checks are not effective for detecting Covid-19.

These spot checks are the equivalent of catching a syllable per minute in a conversation, rather than whole sentences, Smarr said. In the study, the research team noticed that fever onset often happened before subjects were reporting symptoms, and even to those who never reported other symptoms.

It supports the hypothesis that some fever-like events may go unreported or unnoticed without being truly asymptomatic,” the researchers wrote. Wearables therefore may contribute to identifying rates of asymptomatic illness as opposed to unreported illness, which is of special importance in the Covid-19 pandemic.

“We need to make sure that our algorithms work for everyone,” Smarr said. In the future, researchers plan to expand their early detection methods to other infectious diseases, such as the flu. (IANS)

Rihanna was summoned from her seat to accept the honour, with the Prime Minister.

Singer Rihanna was honoured by Prime Minister Mia Mottley at an event which marked Barbados's new status as a republic, which was attended by Prince Charles. Addressing the pop star by her real name, the PM said: "Robyn Rihanna Fenty tomorrow morning shall have conferred upon her the order of national hero of Barbados."

Rihanna was then summoned from her seat to accept the honor, with the Prime Minister managing to rouse a laugh from the singer when she referenced her 2012 hit 'Diamonds', reports femalefirst.co.uk. She added: "On behalf of a grateful nation, but an even prouder people, we therefore present to you, the designee, for the national hero of Barbados." "And to accept on behalf of a grateful nation - you can come my dear - ambassador Robyn Rihanna Fenty, may you continue to shine like a diamond and bring honor to your nation." Rihanna, who was born in the St Michael parish of Barbados, found fame in 2005 after being spotted by a record producer and has since gone on to become one of the most successful female artists of all time with sales of over 250 million and recently reached billionaire status through her Fenty beauty brand.

The Prime Minister continued in her speech: "Commanding the imagination of the world through the pursuit of excellence, her creativity, her discipline, and above all else, her extraordinary commitment to the land of her birth. "Having satisfied that, Ambassador Robyn Rihanna Fenty has given service to Barbados which has been exemplified by visionary and pioneering leadership, extraordinary achievement and the attaining of the highest excellence to the Government of Barbados." It comes after a historic move for Barbados, which has become a republic after almost 400 years and welcomes its first president, Sandra Mason, after removing Queen Elizabeth as head of state.

By IANSlife

Have you ever faced eye redness? Or have witnessed blurry or foggy vision? Or experiencing halos around lights? Or nausea and vomiting are very common for you. You may well be suffering from Glaucoma which needs immediate attention.

Glaucoma is the second most common causes of blindness worldwide, according to a report by World Health Organisation (WHO). Typically, it occurs in people with over the age of 60 however it can occur at any age. It is also estimated that globally 79.6 million people are affected with glaucoma, half of them being Asian population. While in India, around 11.9 million people suffer vision impairment and out of which 1.2 million cases are due to Glaucoma. It is a growing concern for the population in India. Even after these high numbers, the enormous majority remains undiagnosed, and untreated. More than 90 percent of cases of Glaucoma remain undiagnosed.
