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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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: Karnataka Chief Minister's political adviser MP Renukacharya has courted controversy yet again with his remarks targeting the Muslim community at a pro-CAA rally in Karnataka on Monday.

Addressing a rally in support of the new citizenship law, the BJP lawmaker accused Muslims of collecting weapons in mosques instead of praying. "There are few traitors who sit in a masjid and write fatwas. They collect weapons inside the mosque instead of praying. Is this why you want a Masjid," Renukacharya said on Monday.

Renukacharya said he won't hesitate to use the money allotted to Muslims for Hindus. "I will resort to such politics in my taluk where the money allotted for Muslims can be used for Hindus. I will put you [Muslims] in your place and show what politics is," said Renukacharya, who is a close aide of CM BS Yediyurappa.

This is not the first time a Karnataka BJP leader has made communal remarks targeting the minority community. Earlier, BJP MLA Somashekar Reddy had made controversial remarks at a pro-citizenship law protest in Ballari when he asked those opposing the Citizenship (Amendment) Act to think of the "consequences" if the majority community members hit the streets against them.

The MLA had said, "If you do any drama, then if 100 per cent people come, understand what will be your situation. Congress people are lying to you, believing them you are coming on streets. We are 80 per cent, you are 17 per cent, if we react, what will be your situation? Be careful," Reddy had said.

Following outrage, a case was filed against Somashekar Reddy for alleged provocative speech targeting those protesting against the amended citizenship law.

Mangaluru, Mar 7: After coronavirus cases were confirmed in different parts of the country, there has been a sudden jump in demand for mask and safety gears like gloves and sanitizers in Mangaluru and Udupi.

With the increase in demand, medical shop owners said that they were finding it difficult to meet the demand.

In fact, there is a demand for bulk supply of masks and gloves. There was demand for masks when Covid-19 was confirmed in China two months ago. Bulk quantities of masks were purchased in order to supply them to Indian employees working in China. A few private firms had purchased masks from Mangaluru in the month of December.
