Hindu Mahasabha hosts ‘cow urine drinking party’ to cure COVID-19

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.

New Delhi, May 15: Microsoft founder Bill Gates on Friday thanked Prime Minister Narendra Modi for the interaction and stressed that combating the coronavirus pandemic requires global collaboration.

"Thank you for the conversation and partnership PM Narendra Modi. Combating the pandemic requires global collaboration. India's role is key as the world works to minimize social and economic impact, and pave the way to vaccine, testing, and treatment access for all," Bill Gates said.

Prime Minister Narendra Modi on Thursday interacted with philanthropist and Microsoft co-founder Bill Gates and discussed the global response to Covid-19 and the importance of global coordination on scientific innovation to combat the pandemic.

The Prime Minister underlined the conscious approach that India has adopted in its fight against the health crisis - an approach based on ensuring public engagement through appropriate messaging, a PMO release said.

He explained how this people-centric bottom-up approach has helped win acceptability for physical distancing, respect for frontline workers, wearing of masks, maintaining proper hygiene, and respecting lockdown provisions.

They agreed that given India's willingness and capacity to contribute to global efforts, particularly for benefit of fellow developing countries, it was important for India to be included in the ongoing global discussions for coordinating responses to the pandemic.

The Prime Minister also suggested that the Gates Foundation could take the lead in analyzing the necessary changes in lifestyles, economic organisation, social behaviour, modes of disseminating education and healthcare, that would emerge in the post-Covid world, and the associated technological challenges that would need to be addressed.

He said that India would be happy to contribute to such an analytical exercise based on its own experiences.

United Nations, Apr 16: WHO chief Tedros Adhanom Ghebreyesus has welcomed the world health body's cooperation with India to leverage strategies that helped the country win its war against polio into the response to COVID-19 outbreak, saying such joint efforts will help defeat the pandemic.

The World Health Organization (WHO) has said it will work with India's Ministry of Health and Family Welfare to leverage the strategies that helped the country eradicate polio to fight the pandemic.

The WHO's national polio surveillance network will be engaged to strengthen COVID-19 surveillance and its field staff will continue to support immunization and elimination of tuberculosis and other diseases.

“Great news: @MoHFW_INDIA & @WHOSEARO initiated a systematic engagement of @WHO's national polio surveillance network, and other field staff, for India's #COVID19 response, tapping into the best practices & resources that helped win its war against polio,” the WHO director-general tweeted, referring to India's Ministry of Health and Family Welfare and World Health Organization Regional Office for South-East Asia.

According to the Johns Hopkins University data, over 2 million people are infected by the virus and more than 136,000 people have died of the disease globally.

Ghebreyesus expressed gratitude to Health and Family Welfare Minister Harsh Vardhan “for his leadership and collaboration” with WHO. “Through these joint efforts we can defeat the #coronavirus and save lives. Together!”

India eliminated polio in 2014.
According to a WHO press release, Vardhan said in New Delhi that “time and again the Government of India and WHO together have shown our ability, competence and prowess to the whole world. With our combined meticulous work, done with full sincerity and dedication, we were able to get rid of polio.”

“All of you in the field – IDSP (Integrated Disease Surveillance Project), state rapid response teams and WHO - are our ‘surveillance corona warriors'. With your joint efforts we can defeat the coronavirus and save lives,” Vardhan added.

WHO South-East Asia Regional Director Poonam Khetrapal Singh said the National Polio Surveillance Project (WHO-NPSP) played a critical role in strengthening surveillance for polio that generated useful, timely and accurate data to guide policies, strategies and interventions until transmission of the poliovirus was interrupted in the country,” adding that the other WHO field staff involved with elimination of tuberculosis and neglected tropical diseases and hypertension control initiative were also significant resources.

Singh added that “it is now time to use all your experience, knowledge and skills, with the same rigor and discipline that you showed while monitoring polio activities, to support districts with surveillance, contact tracing and containment activities.”

The WHO release said strengths of the NPSP team – surveillance, data management, monitoring and supervision, and responding to local situations and challenges – will be utilized to supplement efforts of National Centre for Disease Control, IDSP and Indian Council of Medical Research to strengthen COVID-19 surveillance.

The NPSP team will also support in sharing information and best practices and help states and districts calibrate their response based on transmission scenarios and local capacities.

The WHO field staff will continue to support immunization and surveillance and elimination of Tuberculosis and Neglected Tropical Diseases, Singh said, adding, “disease outbreaks can negatively impact progress in a range of areas, from maternal and child mortality to vaccine-preventable diseases and other treatable conditions. India had been making stupendous progress in these areas and we cannot afford for India's remarkable progress to be set back or reversed.”
