BJP leader's son, two friends held for gang-raping, blackmailing woman

Bengaluru, Apr 27: As many as 345 Bengaluru-based journalists tested negative for coronavirus on Monday after undergoing a medical check-up got up for them at a hospital here, a top official said.

They had undergone the tests at the Sir C V Raman General Hospital here on April 25 and the results came out negative on Monday. They were among a total of 1,170 journalists who took the tests at the four-day medical check-up camp at the Hospital here from April 23.

"The medical check-up was done in four slots at the Hospital here from Thursday and concluded on Monday. A total of 1,170 journalists undertook the tests, 480 of them on Monday alone, the joint director of the Department of Information and Public Relation D P Muralidhar said.

The test reports of the 480 journalists may come out on Wednesday, he said. Only one journalist tested positive so far and has been admitted to the designated COVID-19 hospital, he said, adding 36 of his primary and secondary contacts have been quarantined.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

New Delhi, Mar 19: Senior Congress leader Oscar Fernandes on Wednesday extolled the virtues of 'gaumutra' and shared an anecdote about a man claiming to have cured his cancer by drinking cow urine to drive his point home.

Participating in a debate in Rajya Sabha on two bills for setting up national commissions for homoeopathy and Indian systems of medicine, the former Union minister said, "My extreme friend Jairam Ramesh pulls my leg, when I talk of 'gaumutra'."

Sharing an anecdote, Fernandes said once during a visit to an ashram near Meerut he had met a person who claimed to have cured his cancer by drinking 'gaumutra'.

Many BJP leaders have earlier spoken about the healing power of 'gaumutra'. The Congress has reacted sharply to such remarks.

He also praised the virtues of the Indian systems of medicine. He said when he had severe pain in knee joint and doctors had suggested for replacement surgery. However, he refused and started doing 'Vajrasana'.

"I started Vajrasana, practising yoga, and today I am able to do wrestling without any difficulty," the septuagenarian leader said.

"When (former) prime minister (Atal Bihari) Vajypee ji had a knee surgery, I thought if I had known him earlier, I would have definitely gone to him and ask him to follow 'Vajrasan' and it could have been cured," he said.

He also claimed to have met a person in US aged around 104 years and moving swiftly as a young man.

"Yoga is our wealth. If you practise yoga, may be our budget cost of health can be reduced by 50 per cent. It's way of life," he said.

"Our own Indian systems of medicine will provide a lot of reliefs even before going to a doctor," he said.

Though Fernandes supported the bills but raised objection over the exclusion of yoga and naturopathy.

"I would urge the minister either to amend the bill or bring an assurance that it will bring a separate legislation to cover yoga and naturopathy," he said.
