Karnataka opens detention centre for illegal immigrants

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mangaluru, Jan 16: A protest against the Citizenship Amendment Act, National Register of Citizens and National Population Register organised by the Muslim Central Committee of the Dakshina Kannada and Udupi districts near Adiyar on Wednesday signalled a snowballing opposition to the measures.

Harsh Mander, former Indian Administrative Service officer-turned-social activist, asserted that the nation’s fight against 'fascist' forces including Bharatiya Janata Party and its parent organisation Rashtriya Swayamsewak Sangh began over 100 years ago when Mahatma Gandhi returned from South Africa and led the freedom movement against the British.

In his address, Mr Mander asserted that the fight against CAA and NRC is also a campaign to save the secular fabric of the nation. He added that the fight began over a century ago when Hindu Mahasabha and other organisations popped up with their vision to turn the nation into a Hindu country.4

Bengaluru, Apr 18: The Karnataka government has fixed the cost of test for COVID-19 in private laboratories at Rs 2,250, an official said on Friday.

"Based on the discussions and negotiations, the cost per test has been fixed at Rs 2,250. This includes the screening test and a confirmatory test," said order by Health and Family Welfare Department's Additional Chief Secretary Jawaid Akhtar.

A total of 16 laboratories (11 government and 5 private) have been approved by the Indian Council of Medical Research (ICMR) for testing samples of possible COVID-19 cases in the state.

Realising that early detection of coronavirus cases and timely treatment was the need of the hour, meetings were held to rope in more private laboratories to conduct COVID-19 sample tests.

As per the protocol by the Centre, testing the samples of suspected COVID-19 cases can be taken up in private laboratories subject to conditions which include sharing the lab data pertaining to the diagnosis of COV1D-19 with the state government and with the ICMR on a timely basis.

As per the Union Health Ministry, 353 people have infected from coronavirus in the state of which 83 are cured and discharged and 13 succumbed to the virus.
