PM Modi's wife Jashodaben suffers minor injuries in road accident, her driver killed

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, May 19: With lockdown 4.0 coming into force, the Karnataka State Road Transport Corporation (KSRTC) started bus services from Mangaluru to various destinations today.

According to officials, buses started plying from Mangaluru to Bengaluru, Mysuru, Shivamogga, Hubballi and other areas with limited passengers. A bus, which left for Bengaluru from Mangaluru had less than 30 passengers on board.

“Depending on the demand, the buses will be operated with 50% of the capacity. Measures have been taken to ensure that social distancing norms are adhered to while purchasing tickets from the counter,” said S N Arun, KSRTC Divisional Controller.

However, the KSRTC is yet to take a decision on operating Nagarasarige buses in the city. 

“Only those destinations, which can be reached by 7 pm has been considered by the KSRTC while operating the buses. As a result, after 11 am, no buses will travel to Bengaluru from Mangaluru. Further, permission will not be accorded for the travelling of pregnant women, children below 10 years old and senior citizens above 60 years old. Thermal scanning is used for checking the temperature of the passengers before boarding the buses. All the buses are sanitised after each trip,” he said.

Further, he said the contact number, name and address of the passengers are collected by the officials during the travel.

Kochi/Thiruvananthapuram, Jan 7: The Managing Director of Muthoot Finance company was injured after miscreants allegedly pelted his car with stones here on Tuesday morning following which one person was reportedly taken into custody.

George Alexander Muthoot, who suffered head injury has been admitted to a private hospital, police said.

A section of employees have been agitating against the Muthoot management over dismissal of 160 staff from the company's 43 branches across the state in December.

The protest is being held under the aegis of the Centre of Indian Trade Unions (CITU).

While the Muthoot management alleged that "CITU goons" were behind the attack that occurred at around 9 am in front of IG office here, the union leaders have maintained that they have no role in the incident.

Reacting to the incident, Labour Minister T P Ramakrishnan said he does not think any of the Muthoot employees were behind the attack.

"The employees were protesting peacefully. Violence is not part of their protest. Even now, in today's incident, I don't think any of the Muthoot employees attacked the MD.

However, it was the management of the company which had always provoked them by not implementing the decisions taken at conciliatory meetings," the Minister said.

If the management was prepared to change its stance, all the issues would be resolved, he said.

CITU leader Ananthavattom Anandan told reporters that they do not believe in such type of violent mode of agitation.

An official of the Confederation of Indian Industries Kerala chapter condemned the incident, saying "it is a matter of great concern".

Well known businessman and founder chairman and CEO of V-Guard Industries, Kochouseph Chittilappilly condemned the attack and said it was unfortunate that such incidents still continue in the state.

“Earlier also such incidents have taken palace. It's highly condemnable. The union leaders will now claim that the incident took place without their knowledge. But without the backing of union, such incidents will never happen,” he said.

Kerala-headquartered Muthoot Finance is the largest gold financing company in India.
