The spread of Covid-19 by an asymptomatic or someone who is not showing any symptoms appears to be less likely, said WHO in the recently published summary of transmission of Covid-19 including symptomatic, pre-symptomatic and asymptomatic patients as per COVID-19 Information & Resources.


The study acquires special importance as India enters the second week of Unlock1.0, with restaurants, religious places, malls opening up, added to a vast population straying out for morning and evening walks.

According to the WHO’s report, “Comprehensive studies on transmission from asymptomatic individuals are difficult to conduct, but the available evidence from contact tracing reported by Member States suggests that asymptomatically-infected individuals are much less likely to transmit the virus than those who develop symptoms.”

Maria Van Kerkhove, the World Health Organization’s technical lead for Covid-19 response in a tweet said “In these data, it is important to breakdown truly asymptomatic vs pre-symptomatic vs mildly symptomatic.

“Also to note that the per cent reported or estimated to be “asymptomatic” is not the same as the per cent that are asymptomatic that actually transmits.”

The WHO said among the available published studies, some have described occurrences of transmission from people who did not have symptoms. For example, among 63 asymptomatically-infected individuals studied in China, there was evidence that 9 (14 per cent) infected another person. Furthermore, among two studies which carefully investigated secondary transmission from cases to contacts, one found no secondary transmission among 91 contacts of 9 asymptomatic cases, while the other reported that 6.4 per cent of cases were attributable to pre-symptomatic transmission.

“The available data, to date, on onward infection from cases without symptoms comes from a limited number of studies with small samples that are subject to possible recall bias and for which fomite transmission cannot be ruled out,” said the WHO.

Some people infected with the COVID-19 virus do not ever develop any symptoms, although they can shed virus which may then be transmitted to others. The WHO said one recent systematic review found that the proportion of asymptomatic cases ranged from 6 to 41 per cent, with a pooled estimate of 16 per cent (12e20), although most studies included in this review have important limitations of poor reporting of symptoms, or did not properly define which symptoms they were investigating. Viable virus has been isolated from specimens of pre-symptomatic and asymptomatic individuals, suggesting, therefore, that people who do not have symptoms may be able to transmit the virus to others, added the WHO.

Van Kerkhove in a media briefing reportedly said that from the data examined by WHO, it still seems to be rare that an asymptomatic person actually transmits onward to a secondary individual.

The WHO said that according to the current evidence, COVID-19 virus is primarily transmitted between people via respiratory droplets and contact routes. “Droplet transmission occurs when a person is in close contact (within 1 metre) with an infected person and exposure to potentially infective respiratory droplets occurs, for example, through coughing, sneezing or very close personal contact resulting in the inoculation of entry portals such as the mouth, nose or conjunctivaee. Therefore, transmission of the COVID-19 virus can occur directly by contact with infected people, or indirectly by contact with surfaces in the immediate environment or with objects used on or by the infected person (e.g., stethoscope or thermometer)”, added the transmission study.

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.

Bitcoin has become an essential crypto asset in modern portfolios and investment funds. The confidence generated in this cryptocurrency will depend a lot on the diversification that companies make in their balance sheets in Bitcoin and the increase of institutional investors that allocate a percentage of their funds in this crypto. American fund manager Cathie Wood makes some interesting predictions, both in the rise that the Bitcoin price will experience in the next 5 years, suggesting these institutional investors allocate 5% of their funds; this will help leverage the Bitcoin market.
