Rains lash Dakshina Kannada, other parts of Karnataka

Karwar, Jun 3: The India Meteorological Department (IMD) has issued an alert, predicting thundershowers and heavy rainfall over north interior Karnataka, coastal Dakshina Kannada and Udupi over the next three days.

With Cyclone Nisarga hitting the Uttara Kannada coast on Tuesday,  parts of coastal Karnataka received heavy rainfall. Gusty winds tore through the coastal towns, as the sea too turned violent with rough waves smashing the shore.

The alert was issued with the advancement of Nisarga from east-central Arabian Sea to north Maharashtra, and adjoining south Gujarat coast. “Though it does not cover Karnataka, the range of cyclonic winds is very big and reaches north interior Karnataka also.

So an alert has been called out,” CS Patil, director in-charge, IMD, Bengaluru, said. The weather department has forecast a severe cyclonic storm and then a depression. Patil said formation of systems is a common factor before the onset of the monsoon and they help in its advancement.

“Cyclone Nisarga is helping in the quick advancement of the southwest monsoon to Karnataka, and the monsoon is likely to arrive before the scheduled date as conditions are favourable,” he added.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Apr 23: The Karnataka government on Wednesday promulgated 'The Karnataka Epidemic Diseases Ordinance 2020' that provides the state with a power to seal borders, restrict essential services and punish those attacking public servants and damaging public property.

The Ordinance comes after violence in Padarayanapura when the police and BBMP officials were attacked while they tried to take some secondary contacts of a deceased COVID-19 patient into quarantine on April 19.

The Ordinance, which was promulgated after the Centre's guidelines in this regard, said, "The offender shall be liable for a penalty of twice the value of public or private property damaged as determined by the Deputy Commissioner after an inquiry."

It further said that if the penalty is not paid by the offender, then the amount shall be recovered under provisions of the Karnataka Land Revenue Act, 1964. The Deputy Commissioner can even attach the property of such offender in due course.

Also, abetment of offence would attract imprisonment of up to two years and a penalty of Rs 10,000 or both.

"No person shall commit or attempt to commit or instigate, incite or otherwise abet the commission of offence to cause loss or damage to any public or private property in any area when restrictions and regulations are in force to contain any epidemic disease," the Ordinance said.

Whoever contravenes such provision shall be punished with imprisonment for a term which shall not be less than six months, but may extend to three years and with fine which may extend to Rs 50,000, it added.

On Wednesday, the Centre brought an Ordinance to end violence against health workers, making it a cognisable and non-bailable offence with imprisonment up to seven years for those found guilty.

"We have brought an Ordinance under which any attack on health workers will be a cognisable and non-bailable offence. In the case of grievous injuries, the accused can be sentenced from six months to seven years. They can be penalised from Rs 1 lakh to Rs 5 lakhs," Union Minister Prakash Javadekar briefed media after Cabinet meeting.

Javadekar said that an amendment will be made to the Epidemic Diseases Act, 1897 and ordinance will be implemented.
This comes amid nationwide lockdown in the wake of COVID-19.
