Dubai: Major fire beaks out at Address Downtown hotel on New Year eve

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jun 25: Karnataka Chief Minister BS Yediyurappa on Thursday asked people to cooperate by following the measures put in place for the control of COVID-19 if they don't want another lockdown or sealing in Bengaluru.

Amid talks about re-imposing lockdown in the city following the recent spike in cases, the Chief Minister said he will hold discussions on Thursday and Friday regarding the strict measures that need to be taken to control the virus.

"COVID pandemic is increasing, we are making all efforts and we have even sealed some areas. Today afternoon at Krishna (the CM's home office) I have called a meeting with Ministers and officials and will discuss the strict measures to be taken to control COVID," Mr Yediyurappa said.

Speaking to reporters, he said, "Tomorrow noon I have called a meeting of legislators of all political parties from Bengaluru and all Ministers from the city to discuss with them, seek their opinion and take stringent measures."

Citing an increase in cases, Health Minister B Sriramulu on Tuesday had said the government may have to think about imposing lockdown in the city if the situation continues.

Following this several Ministers in the state cabinet on Wednesday had said, any decision on re-imposing lockdown in the city will be taken only after consulting experts.

Some reports had even suggested that a decision on lockdown is likely at the cabinet meeting scheduled today.

The Chief Minister said there is no lockdown in the entire city, adding only in a few areas it has been imposed and would continue.

Concerned over the increase in COVID-19 cases in the city, Mr Yediyurappa on Monday had directed officials to implement lockdown measures strictly in certain clusters which have reported greater number of coronavirus infections.

The city's busy K R Market and Kalasipalya Market have been sealed for 15 days by the civic body Bruhat Bengaluru Mahanagara Palike (BBMP) as part of measures to check the spread of the deadly virus.

Stating that Bengaluru is a model for the whole country in COVID-19 management, Mr Yediyurappa on Thursday said, when you compare with other major cities, "we have not yet lost control."

A total of 1,678 cases of COVID-19 have been reported in the city till last evening.

This includes 78 deaths and 475 discharges.

The number of COVID-19 cases in the state which stood at 3,408 as of June 1 has crossed the 10,000 mark on Wednesday with the state capital topping the districts in the infection count.

Seeking public cooperation in controlling the spread of the virus, Yediyurappa said social distancing and other measures in place were not followed, there has been spread to slums and other places.

"If you don't want Bengaluru to be sealed once again please cooperate and maintain distance," he added.

Mr Yediyurappa also said, the government has taken all measures for the safe conduct of SSLC (class 10) exams from today, and students should come out and write exams for their bright future.
