Mangaluru to be open defecation free city by October 2

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Kalaburagi, Jan 21: A team of bomb disposal squad along with sniffer dog visited Kalaburagi Railway Station on Tuesday morning.

In the wake of the bomb found at Mangalore Airport on Monday morning, the team visited the railway station as a precautionary measure.

Mangaluru, May 24: Muslims across coastal Karnataka today observed Eid Al-Fitr by offering Eid prayers at home instead of mosques and Eidgahs.

For the first time the cities of Mangaluru and Udupi wore a deserted look on the day of Eid. Strict implementation of the lockdown was seen in the both cities. All vehicles except those transporting essentials remained off the roads.

Following the orders of orders of the deputy commissioners of the Dakshina Kannada and Udupi and guidance of religious scholars and Qadhis, Muslims preferred not to venture out of homes on the day of Eid. The 36 hours of complete lockdown which came into force yesterday at 7 p.m. will relaxed tomorrow morning at 7 a.m.

The Eidgah at Light House Hill area of the city and other prominent mosques, where thousands used to gather to offer namaz during festivals, were empty today.

Photos of simple Eid celebrations were share on social media to keep the spirit of festival alive in times of pandemic.

This time Muslims in the region had also decided not to buy any new clothes for Eid. Campaigns were run in the moth of Ramadan to encourage the Muslims to donate the amount of new clothes to the needy instead.

Throughout the month of Ramadan Muslim organisations were distributing food among the stranded migrant labourers in the region.
