BJP leaders tried to lure me Rs 30-cr cash plus ministerial berth: Lakshmi Hebbalkar

Kasaragod, Apr 10: Eleven people died so far in Kerala's northern district Kasargod as they could not access medical facilities in Mangaloru since the border roads were blocked by the Karnataka Government, Kerala Chief Minister Pinarayi Vijayan said.

Addressing a press conference at the Government Secretariat here, the Chief Minister said, "It is really unfortunate that people from Kasargod district in Kerala are still being denied treatment in hospitals at Mangalore in Karnataka State."

"We will improve the medical facilities in Kasargod and if necessary, patients will be airlifted to the neighbouring districts in Kerala to provide emergency medical assistance," he added.

Mangaluru, June 6: Four persons were arrested by the Mulki police today in connection with the murder of Abdul Lateef, a 38-year-old businessman.

The arrested are: Mohammed Hasim (27), Nissar alias Riyaz (33), and Mohammed Razim (24), all residents of Mulki, and Aboobakar Siddique (27), a resident of Udupi.

The weapons and vehicles used for murder have been confiscated. Investigation is in progress to find out the motive behind the murder and the arrest of remaining accused.

Abdul Lateef, his father-in-law Muneer, latter’s son Ijaz and relative Imran were returning from Vijaya Bank at Mulki when a gang of nine miscreants waylaid their car and attacked with sharp weapons.

The gang comprised of Hakeem, Wafa, Asim, Siddique, Nissar, Bava, Farhan, Razeem and Siddiq.  While four of them are arrested, police continued hunt to nab other accused.

Abdul Lateef breathed his last while being taken to hospital. Others are undergoing treatment at a private hospital 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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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
