Managluru: Eight held for clash during BJP’s victory rally in front of mosque

Mangaluru, Mar 22: A 22-year-old man from Bhatkal who had returned from Dubai on March 19 has tested positive for coronavirus.

Sindhu B Rupesh, Deputy Commissioner of Dakshina Kannada confrimed this today.

The youth, after landing at Mangaluru International Airport had got admitted to Govt Wenlock Hospital.

The total number of coronavirus positive patients in India rose to 342 on Sunday, as per the Indian Council of Medical Research (ICMR).

A total of 16,999 samples from 16,109 individuals have been tested for COVID-19 as of 10:00 am on March 22, as per ICMR data.

India reported two deaths today from the highly contagious virus - one each in Maharashtra and Bihar - taking the tally to six, as per state authorities.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jan 21: A massive protest against the Citizenship Amendment Act (CAA), National Register of Citizens (NRC), and National Population Register (NPR) was witnessed at Shivajinagar's Chandni Chowk area on Tuesday.

Scores of people came together carrying national flags and placards to register their protest in the city.

Speaking to ANI, a protester said, "People of all religious community have assembled here in Chandni Chowk to protest against CAA, NRC, and NPR. We the people of India are against this law."

Terming the law as anti-constitutional, he said that we support all the states who oppose the CAA. We demand the revocation of CAA and the government should remove conditions in NPR which lead to NRC.

CAA grants citizenship to Hindu, Sikh, Jain, Parsi, Buddhist and Christian communities fleeing religious persecution from Pakistan, Afghanistan, and Bangladesh and who came to India on or before December 31, 2014.
