Muslim organisations in Mangaluru unite against Uniform Civil Code

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Mar 24: The state government on Tuesday published names and addresses of 14,000 people who have been placed under home quarantine, on its website.  

A district wise break up of the home quarantine patients was also provided.  

Notably, the number of coronavirus cases has risen to 41 in the state.

Thrissur, Mar 7: A local temple in Kerala is at the centre of a social media storm after the picture of a ''Brahmins-only toilet'' outside its main campus went viral on online platforms, prompting the management to remove the signboard.

The picture of three toilets, with signboards showing "Men", "Women" and "Brahmins", at the Kuttumukku Mahadeva Temple in Thrissur, has gone viral with many social media users viewing it as an unethical practise that can portray the progressive state in a bad light.

However, temple officials said the toilets were located outside the main campus and the board was brought to their notice only now.

Kannan, an official of the temple committee, said the board was placed nearly two decades ago and nobody raised any complaint against it so far.

"That particular toilet was being used by priests and other temple employees. We didn't even notice that board... As soon as we came to know about it, we removed it and affixed a staff-only board," he told PTI.

Also a CPI-M functionary and ward councillor, Kannan said the shrine and it's management was against all kinds of unethical customs.

The temple official said they were planning to pursue legal measures against the man who posted the photo of the toilets on social media.

"We suspect that he did it deliberately to create issues during the time of the festival and to tarnish the shrine's reputation. Not only that, the photo he shared was an old one though he claimed that it was taken during the time of the festival, " he said.
