Martyred NSG commando Niranjan Kumar's body reaches Bengaluru

Chamarajanagar, Jan 3: The residents of Galipura layout in Chamarajanagar city boycotted the annual Community Based Survey (CBS), conducted by the Health and Family Welfare department, mistaking it to be the National Register of Citizens (NRC).

Majority of the residents in the layout belong to Muslim community. The people, who mistook CBS to the NRC survey, got into arguments with the Asha workers, who were given the responsibility of collecting information. They even tore the forms into pieces and vent their ire.

The Health Department conducts CBS every year in the urban areas and collects all details including Aadhaar number, residential address, details of family members, health problems and others.

Fifteen Asha workers were deputed for the survey in the layout. A few youths started questioning them alleging it to be an NRC survey and started arguing with them.
Tahsildar Mahesh, District Health and Family Welfare Officer Dr N C Ravi, with the help of Muslim leaders cleared the confusion. The community leaders assured of explaining it to the residents and extend cooperation to the survey.

Mangaluru, Apr 1: The rush for purchase of essential commodities has eased in several places in Dakshina Kannada with the relaxation of lockdown from Wednesday between 7 am and 12 noon by the district administration. However, a few markets in Mangaluru still had queues in front of vegetable shops on Wednesday.

Vegetable shops and markets in Mallikatte, Kadri, Bejai-Kapikad, Urwastore, Mannagudda and Carstreet areas were crowded with people violating social distancing norms due to the coronavirus crisis.

To avoid swelling of crowds at Central Market in Mangaluru, the market was opened only for wholesalers to collect vegetables. The entry of public to Central Market was prohibited.

MCC Commissioner Ajith Kumar Hegde Shanady said that retail sale is prohibited at Central Market.

The Surathkal market too has been closed from April and traders from the market are allowed to sell essential commodities at alternative locations from 7 am to 12 noon.

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
