Udupi: BJP protests against arrest of accused in Husainabba death case; demands justice for dead cows

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jul 1: Eighteen private hospitals here have been slapped with a show-cause notice after a 52-year old patient with influenza-like illness symptoms died here on being allegedly denied admission by them citing "non- availability" of beds. 

Health Minister B Sriramulu on Wednesdy said refusal to provide treatment was not only inhuman but also illegal as he tagged a copy of the notice in a tweet. 

"Notice has been served to the hospitals taking cognisance of the (media) reports about the denial of admission to a patient in emergency. Denying medical assistance during emergency is not only inhuman but also illegal," he tweeted. According to a report, the son and nephew of the patient took him to the 18 hospitals on Saturday and Sunday but he was not admitted on the pretext of non-availability of beds or ventilators. 

The man died later. The Commissioner of Health and Family Welfare issued the show-cause notice to the top authorities of the hospitals under the Karnataka Private Medical Establishment (KPME) Act, 2007. 

"By denying admission to the patient, your hospitals have violated the provisions of the KPME Act. You are liable for legal action," the notice said, seeking replies within 24 hours as to why action should not be against the hospitals. 

This was a "clear violation" of providing medical assistance and admission necessitated under the agreed provision of the KPME registration. Private medical establishments cannot refuse or avoid treatment to patients suffering from COVID-19 or having symptoms, the common notice added. 

The incident comes in the backdop of repeated instructions by the government that hospitals cannot deny admission to the patients suffering from coronavirus or having symptoms.

Davanagere, Jul 4: Referring to allegations made by former Karnataka Chief Minister Siddaramaiah's charge about corruption while purchasing COVID-19 equipment, Health Minister B Sriramulu said the state government is ready for any kind of probe in this regard.

Speaking to media persons here on Saturday, he said the government has maintained accounts for each purchase of equipment related to Covid-19. 

"So, Congress leader's allegations are far from the truth. Siddaramaiah has vast political experience. It is unbecoming of such a leader to make ridiculous allegations. The government is ready to release white paper on purchase of equipment related to Covid-19," he said.

He said Karnataka stands third in the country in collection of throat swabs and examination of people related to Covid-19. The entire country has hailed Karnataka's role in containing Covid-19, Sriramulu he added.
