Yeddyurappa requests Centre to open NIA office in Mangaluru

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bengaluru, May 13: Former chief minister and senior Congress leader Siddaramaiah on Wednesday called the measures announced by Finance Minister Nirmala Sitharaman as 'disastrous' and said it is 'non-existent' in terms of benefits to poor migrants, labourers, contract employees and farmers.

"The first set of measures announced by @FinMinIndia @nsitharaman, after 8 PM speech by @narendramodi, is disastrous & non-existent in terms of benefits to poor migrants, labourers, contract employees, farmers, etc," Siddaramaiah said in a tweet.

The Congress leader said most of the intended benefits may not reach the end recipient.

This comes a day after Prime Minister Narendra Modi announced a Rs 20 lakh crore special economic package to revive the COVID-19 hit economy.

"The contribution by the government for the schemes announced are mostly notional and less of actuals and the devil lies in the detail," the Congress leader said in another tweet.

After Sitharaman announced support measures for MSMEs, Siddaramaiah said, "The credit infusion to MSMEs may help them clear dues to vendors but it is doubtful if they shall utilise the credit available to pay their labourers & to prevent job cuts. @FinMinIndia should have taken measures to pay part of the salaries to the employees in MSMEs."

Further questioning the Centre on 'ignoring the spending for boosting consumption', Siddaramaiah said, "The government is interested in capital infusion in the form of credits but totally ignorant of the actual spending that needs to be done to boost consumption. How can credit be considered as government spending?"

Siddaramaiah said the next set of measures should benefit the marginalised sections.

"Will be looking forward to next set of measures & I hope it will be something to benefit the marginalised sections. Direct benefits to the poorest sections will help them survive this pandemic. COVID-19 fight should not be another perception battle but a real one," he added in another tweet.

Sitharaman earlier announced Rs 3 lakh crore collateral-free automatic loans for businesses, including MSMEs.

Besides this, she also stated that to provide stressed MSMEs with equity support, the government will facilitate the provision of Rs 20,000 crore as subordinate debt.

Thiruvananthapuram, May 29: Chief Minister Pinarayi Vijayan said that fishing in Kerala coast and southeast Arabian Sea has been completely banned from Thursday midnight as the state is expected to receive rainfall early next month.

"India Meteorological Department (IMD) has informed that southwest monsoon will arrive in Kerala coast by the first week of June. The state will receive rainfall in the next five days. Fishing in Kerala coast and the southeast Arabian sea to be completely banned from midnight," Vijayan said.

On Thursday, the IMD announced that conditions are favourable in Kerala for the onset of the southwest monsoon on June 1.

"A low-pressure area is likely to form over the southeast and adjoining east-central Arabian Sea from May 31 to June 4, 2020. In view of this, conditions are very likely to become favourable from June 1, 2020 for the onset of southwest monsoon over Kerala," the IMD said in its bulletin.

It also stated that the southwest monsoon has further advanced into some parts of Maldives-Comorin area, some more parts of south Bay of Bengal, remaining parts of Andaman Sea and Andaman and the Nicobar Islands.
