As new research claiming that Covid-19 can survive longer on bank notes — up to 28 days at 20 degree Celsius along with humidity — started doing the rounds amid the corona surge, health experts said on Monday that people should avoid being paranoid and must take proper pandemic-related precautions.

Researchers at the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia’s national science agency, claimed that that SARS-CoV-2 can remain infectious on surfaces for long periods of time as it can survive for up to 28 days on common surfaces including bank notes, glass such as that found on mobile phone screens and stainless steel.

Stressing that there are loopholes in this study, Dr Richa Sareen, Consultant- Pulmonology, Critical Care and Sleep Medicine at Fortis Hospital Vasant Kunj, Delhi, said that the research was carried out in the dark, with stable temperature (20 degree) and humidity.

“These are virus friendly conditions and do not simulate the actual temperature and humidity variations. Earlier studies had documented the presence of virus on bank notes for up to two-three days and glass and steel for six-seven days, which seems more acceptable,” Sareen told IANS.

Another important point to remember here, she said, is that fomites (inanimate objects) are not the main source of spread of Covid-19 infection.

“It is primarily spread by aerosols, droplets and personal contact”.

The research, undertaken at the Australian Centre for Disease Preparedness (ACDP) in Geelong, found that SARS-CoV-2 survived longer at lower temperatures and tended to survive longer on non-porous or smooth surfaces, compared to porous complex surfaces such as cotton.

Dr Suranjit Chatterjee, senior consultant for internal medicine at Indraprastha Apollo Hospital, said that coronavirus is transmitted mostly through direct contact with an infected person, especially the virus-laden particles they emit while coughing, sneezing, speaking, singing and even breathing.

“The direct contact with the infected person remains the major source of spreading the virus. The findings did not necessarily reflect the potential to pick up the virus from casual contact, as the presence of the virus in the study was detected by laboratory tools, not fingers and hands as would be the case in everyday life,” Chatterjee elaborated.

“Such findings are minor causes for the spread of the virus and can potentially create paranoia among the people,” he warned.

However, money changes hands frequently and can pick up all sorts of bacteria and viruses and things like that.

“When possible it’s a good idea to use contactless payments. If you want to protect yourself just maintain the basic principles of wearing a mask, maintaining social distancing, washing hands and maintaining coughing and sneezing etiquette,” Chatterjee told IANS.

The researchers of the Australian study argued that for context, similar experiments for Influenza A have found that it survived on surfaces for 17 days, “which highlights just how resilient SARS-CoV-2 is”.

According to Dr Naveen Aggarwal, Head and Senior Consultant, Pathologist, Action Cancer Hospital, favourable surroundings and weather are the prime conditions of any virus’ survival or growth.

“In winters, coronavirus can survive more on paper and can contribute significantly in transmission especially in a country like India. Hence referring to this problem, digital transactions and paperless work are the key,” Aggarwal said. (IANS)

The aim of the book is to teach children that families can exist in different forms, and show them how to accept the diversity in family backgrounds.

By Siddhi Jain

Delhi-based author Pritisha Borthakur is set to release her new book, 'Puhor and Niyor's Mural of Family Stories'. The 1,404-word children's book was put together to address a new kind of societal debacle in the family system. The author says the aim is to teach children that families can exist in different forms, and show them how to accept the diversity in family backgrounds.

The author who named the book after her twin sons -- Puhor and Niyor -- is a parent who has seen and heard the tales of ridicule and discrimination suffered by many in India and beyond. She says the book is an artistic illustration for kids that details how different families can live and coexist. Whether it's children with two dads or two moms, children with a single dad or single mom, and even multiracial family units, Borthakur's book teaches love, understanding, and compassion towards unconventional families.

Beyond race, gender, color, and ethnicity which have formed the bases for discrimination since the beginning of time, this book aims to bring to light a largely ignored issue. For so long, single parents have been treated like a taboo without any attempt to understand their situations; no one really cares how or why one's marriage ended but just wants to treat single parents as villains simply for choosing happiness and loving their children.

Homosexual parents, a relatively new family system, is another form that has suffered hate and discrimination for many years. Pritisha emphasizes the need to understand that diversity in people and family is what makes the world beautiful and colourful. 'Puhor and Niyor's Mural of Family Stories' is a firm but compassionate statement against all forms of discrimination on the bases of sexual identity, gender, race, and even differences in background

Clean and maintained hands boost confidence in daily life activities.

If you feel that clean and well-groomed hands are just an essential prerequisite for women, you might like to think twice. Men should equally pay attention to their hands because our hand houses 1,500 bacteria living on each square centimeter of its skin. You can easily assume what havoc it can create in our body because in India we have the culture of eating with our hands and spaces beneath nails can become breeding heaven for germs. Moreover, clean and maintained hands boost confidence in their daily life activities. Therefore, it's important to keep your hands clean irrespective of your gender by washing or sanitizing at regular intervals. And, to keep them groomed, you don't have to visit a salon.

Rajesh U Pandya, Managing Director, KAI India, gives easy and completely doable tips to follow at home:

* Refrain from harsh soaps: You should be mindful of the soap you are using to wash your hands. Your soap can have a moisturizing element in it like aloe vera or shea butter. Ensure that you're washing your hands with normal water as hot water can make your hand's skin dry and scaly.

Bitcoin has become an essential crypto asset in modern portfolios and investment funds.
