HJV leader Jagadish Karanth arrested over communal remarks against Puttur cop

Bengaluru, Apr 25: Former Karnataka Health minister and senior Congress leader Dr H C Mahadevappa on Saturday urged the state government to chalk out a comprehensive plan to conduct tests among the vulnerable sections in the society to impede the spread of the dreaded COVID-19 pandemic in the state.

Speaking to media persons, Dr Mahadevappa, felt that only restricting people to remain indoors will not suffice to tackle the spread of the contagious disease he said that "There needs to step up testing the people especially belonging to the vulnerable sections of the society".

Maintaining that the COVID-19 disease, which has progressed itself as a pandemic, across the globe, former Health Minister said that "there is also a need to fight the menace with multiple dimension, as it has potential to cause damage not only the social life of the people but also their livelihood".

The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study

Jan 13: India lost more than $1.33 billion to internet restrictions in 2019 as Prime Minister Narendra Modi’s government pushed ahead with his party’s Hindu nationalist agenda, raising tensions and sparking nationwide protests.

The worst shutdown has been in Kashmir, where after intermittent closures in the first half of the year, the internet has been cut off since Aug. 5 following the government’s decision to revoke the special autonomous status of the country’s only Muslim-majority state, a study said. The prologued closure was criticized by India’s highest court, which ruled Friday that the “limitless” internet shutdown enforced by the government for the last five months was illegal and asked that it be reviewed.

India imposed more internet restrictions than any other large democracy, according to the Cost of Internet Shutdowns 2019 report released by Top10VPN, a U.K.-based digital privacy and security research group. The South Asian nation recorded the third-highest losses after Iraq and Sudan, which lost $2.31 billion and $1.86 billion respectively to disruptions. Worldwide internet restrictions caused losses worth $8.05 billion, the report said.

The cost of internet blackouts was calculated using indicators from groups including the World Bank, International Telecommunication Union, and the Delhi-based Software Freedom Law Center. It includes social media shutdowns in its calculations.

India’s ministry of information and technology didn’t respond to an email seeking a response to the report’s findings.

‘Conservative Estimates’

Through 2019, India shut access to the internet for over 4,000 hours. The report added shutdowns in India were often narrowly targeted, down to the level of blocking city districts for a few hours to allow security forces to restore order. Many of these incidents were not included in the report.

“These are conservative estimates,” said Simon Migliano, head of research at U.K.-based Top10VPN. “Internet shutdowns are increasing and it shows a damaging trend.”

India’s other major internet disruptions coincided with two moves by the government that affect India’s Muslim minority. The first disruption took place in November in the states of Uttar Pradesh and Rajasthan after the Supreme Court handed a victory to Hindu groups over Muslim petitioners in a long-simmering dispute over a plot of land.

There were further disruptions in December when protests erupted against the introduction of a religion-based law that allows undocumented migrants of all faiths except Islam from neighbouring countries to seek Indian citizenship. The government enforced shutdowns across Uttar Pradesh and some Northeastern states in order to quell the protests, the report said.
