Suspected terrorist Parashuram Waghmore is RSS activist, reveals Muthalik

Belagavi, Jan 17: Maharashtra Minister of State for Public Health, Medical Education, FDA and Textiles Rajendra Patil-Yadravkar who had come here to participate in the martyrs day programme of Maharashtra Ekikaran Samiti (MES) was detained by the police and escorted back till the state borders on Friday.

MES had organised its annual martyrs day programme at Hutatma Circle here. Its leaders had earlier been asked by the District Administration and City Police to ensure that none of the political leaders from Maharashtra participate and create law and order problems by their anti-state statements.

Patil had managed to sneak into the city through a route which was not manned by the police. He came in an auto-rickshaw to the programme venue.

Police personnel present for security took him into their custody and later escorted him till the state’s borders with Maharashtra at Kognoli on the Pune-Bengaluru national highway.

MES leaders alleged that the police personnel violated protocol while taking the incumbent minister into their custody and they also roughed him up.

All vehicles entering the city from different routes and particularly from Maharashtra were screened to confirm that political leaders from the neighbouring state do not participate in the martyrs day programme and create problems by their statements that also affect law and order along with linguistic harmony.

It was not known if Patil had landed in the city on Thursday and managed to reach the programme venue without getting noticed by using an auto-rickshaw.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, July 13: Dakshina Kannada district in-charge Minister Kota Srinivas Poojary on Monday said that all COVID-19 patients in the district will be treated for free in the hospitals of all medical colleges in the district.

Speaking to newsmen after visiting the COVID-19 treatment facility at KMC Hospital here, Poojary stated that all COVID-19 patients including BPL families, APL families, migrant workers and those without a ration card, will be treated free of charge in the district’s medical colleges. Patients can show their Aadhaar card at the hospital and get free treatment.

Provision of free treatment for COVID-19 patients at Wenlock hospital will be continued. In Dakshina Kannada district, the number of people recovering from the virus and being discharged hospitals is high. There is no need for the people of the district to panic. The government is committed to the health of the people, Poojary said.
