Thousands travel by boats to join massive anti-CAA protest 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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

New Delhi, Feb 29: The arsonists, who were allegedly hired by the pro-CAA politicians in Delhi to unleash violence against Muslims, did not even spare the residence of Border Security Force personnel Mohammed Anees.

While the jawan, who has spent three years guarding the borders along Jammu and Kashmir, had hoped that his job profile mentioned on the nameplate hung outside their two-storey house would discourage the vandals, he was proved wrong. 

The nameplate on house number 76 in Khas Khajuri Gali clearly mentioned it was the property of a security force personnel who protects India’s borders from foreign invasions. Yet, it was burned down on the afternoon of February 25.

First, the ruthless goons set the vehicles parked outside the jawan’s house on fire, then they torched his home. Stones were also pelted at his house amid slogans of “idhar aa Pakistani, tujhe naagarikta dete hai” (Come here Pakistani, get your citizenship). 

Apart from Anees, his father Mohammed Moonis, 55, uncle Mohd Ahmed, 59, and 18-year-old cousin Niha Parveen were in the house. Sensing what was about to go down next, they all escaped from the house, and were helped by paramilitary troops.

Charred remains of the house now stand where the house was till three days ago. In the two lanes of Khajuri Khas near Anees’s house, 35 houses were set on fire. 

The loss suffered by the BSF soldier’s family was perhaps greater as they had kept all their life’s savings inside: two weddings in the family were to take place in the next three months.

Niha Parveen was to get married in April and Anees himself was to get married the following month. “All the things we collected all our life, jewellery – two gold necklaces, silver jewellery, it is all gone,” the family said.

“We used to buy jewellery on instalments… used to give money every month and collected this jewellery,” they said. Rs 3 lakh in cash for the wedding arrangements also got burnt along with other valuables and all their belongings.

Khajuri Khas is a Hindu-majority area, but Anees’s family says no neighbour of theirs was involved in the attack. “People came from outside.” Instead, their Hindu neighbours were asking the rioters to leave. They requested them to leave and helped douse the vehicles on fire.

Mangaluru, Apr 7: The virology lab set up in Wenlock Hospital here to test COVID-19 samples will start functioning from Tuesday, Karnataka District in-charge Minister Kota Srinivas Poojary said.

In his tweeter Mr Poojary said “After receiving approval from the Indian Council of Medical Research (ICMR) and National Institute of Virology (NIV), the Virology Research and Diagnostic Laboratory set up at district Wenlock will start operating from April 7. The samples for COVID-19 will be tested in the district itself. I thank the state government for helping us set up the lab.”

The new Lab becomes the 10th government lab for testing COVID-19 samples in the state.
