Jaimala directs officials to give priority to the safety of schoolchildren during monsoon

Dubai, Feb 13: An Indian expatriate found to be infected with coronavirus in the UAE on February 10 is in a stable condition, the Indian Embassy told Gulf News.

“The Indian is a 36-year-old male,” an embassy official said, adding “he a resident of the UAE”.

However, the official did not say if the man had any travel history to China and also refused to divulge which state he hailed from.

On February 10, the Ministry of Health said the Indian national was found infected with coronavirus in the latest such case in the UAE. “The Indian national had interacted with a recently diagnosed person,” the ministry had said in a statement.

"All reported cases are in stable condition, except for one case, who is being put under close observation by a team of senior consultants at the Intensive Care Unit," added the statement.

The man is among the eight cases of coronavirus detected in the UAE so far. Others include six Chinese nationals and one from Philippines.

Earlier this week, the UAE announced that one of the infected patients, a 73-year-old Chinese national, Liu Yujia, had recovered.

Bengaluru, May 11: Karnataka Chief Minister BS Yediyurappa on Monday inaugurated four buses that have been converted into COVID-19 testing facilities in Bengaluru.

State Deputy Chief Minister C N Ashwath Narayan, Karnataka Revenue Minister R Ashoka and Member of Parliament from Bengaluru South Tejasvi Surya were also present.

"The mobile fever clinic bus initiative was taken by Sanchit Gaurav, Founder and CEO of Housejoy, in association with the Government of Karnataka, the Karnataka State Road Transport Corporation (KSRTC), MP Tejaswi Surya, other partners, to increase the number of COVID tests across Bengaluru and win the fight against the virus," said KSRTC in a statement.

The bus is divided into two zones with beds and a consultation area, maintaining proper hygiene conditions.

The KSRTC said there will be four teams with four mobile bus clinics across Bengaluru - each team comprising of one doctor, three nurses and one lab technician with several volunteers facilitating the process.

The teams will be starting from red zones and will try to screen the maximum number of residents from these zones for symptoms and quarantine those who test positive.

"The testing process will start by providing free glucose, blood pressure test and COVID-19 symptoms consultation for all residents," KSRTC added.

If anyone showcases any COVID-19 symptoms, their swab will be collected immediately for testing by Biognosys Technologies (ICMR certified).

Further, the information will be provided to the government and place the person under quarantine.

"KSRTC has already initiated this mobile fever clinic buses with the association of the District Administration in Mysuru, Mandya, Tumkur, Mangaluru, Bagalkote, Hubli, Belagavi, Bengaluru and Raichur," it said.

According to the KSRTC on April 25, the cost of this clinic construction on a bus is Rs 50,000.

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
