Son dead, but they' show no sympathy for CM Siddaramaiah

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Udupi, Mar 6: District Health Officer Sudheer Chandra said that health department had compiled a list of foreigners visiting the Temple town Udupi and ensure that they are not infected with Coronavirus.

Addressing media persons at District Government Hospital in Ajjarkad on Friday, he said the Isolation Unit set up with five beds to treat the new Coronavirus infection includes two beds with Ventilator facility. Isolation wards with three beds were set up in Kundapur and Karkala taluks to treat the affected.

In order to prevent the spread of Coronavirus, Committees were formed at District and Taluk level, he added.

Bengaluru, Jul 16: Former union minister and Senior Congress leader Veerappa Moily on Wednesday said that if at all there is a political future for Sachin Pilot it is in the Congress party.

While speaking to news agency, Moily said Sachin Pilot achieved everything by being in Congress party.

"Sachin Pilot became MP, union minister in UPA-II, PCC president in Rajasthan and Deputy Chief Minister of Rajasthan. Whatever grievances you have, it needs to be resolved within the forum of the party. There is no hurry for Sachin Pilot. If at all there is a future for him it is in the Congress party. He has to realise that. He says he won't join BJP, it is good," Moily said.

The former Union Minister Moily further said that Pilot could not become Chief Minister as in Congress, the high command sends an observer and opinion of MLAs is ascertained, be it in Madhya Pradesh or Rajasthan.

"The leader who enjoys the support of elected MLAs is made Chief Minister," Moily said.
On July 14, Congress party had sacked Sachin Pilot from the post of Deputy Chief Minister of Rajasthan and also from PCC president.

The Rajasthan Congress is in turmoil over the past few days. State Chief Minister Ashok Gehlot has blamed the BJP for attempting to destabilise the state government by poaching MLAs. The Congress government in the state is facing a political crisis after simmering differences between Pilot and Ashok Gehlot came out in the open.

A controversy broke out in Rajasthan after Special Operation Group (SOG) sent a notice to Pilot to record his statement in the case registered by SOG in the alleged poaching of Congress MLAs in the state.
