I have no faith in CBI, Gauri's mother tells CM

Udupi, Apr 21:  Four walk-in sample collection units for COVID-19 test has been installed in the district, sources said on Monday.

The units have been installed at Udupi’s T M A Pai Hospital and district hospital and at Kundapura and Karkala taluk hospitals by Indian Medical Association, Udupi Branch along with Rotary Club and Red Cross Society.

Udupi district was declared COVID-19-free after all three COVID-19 positive patients were discharged after recovery and were now in home quarantine, the sources added.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Dubai, May 3: Over 150,000 Indians in the UAE, who wish to return home amid the coronavirus lockdown, have applied through the online registration process to the Indian missions here, according to media reports.

The Indian missions in the country last week opened online registration for the expatriates who wish to fly back home after getting stuck in the country amidst the lockdown due to the coronavirus pandemic.

As of 6 pm on Saturday, we received more than 150,000 registrations, Consul General of India in Dubai Vipul told the Gulf News on Saturday.

A quarter of them want to return to their homeland after losing their jobs, he said.

According to a report in the Khaleej Times on Sunday, about 40 per cent of the applicants who have registered are blue-collared workers and 20 per cent are working professionals.

"Roughly 20 per cent have suffered job losses and about 55 per cent of the total applicants are from Kerala," Neeraj Aggarwal, Consul, Press, Information, Culture was quoted as saying in the report.

Aggarwal said that the figures would change as they are expecting registrations from workers from other states, including Telangana, Uttar Pradesh, and Bihar.

About 10 per cent of the applicants are visit and tourist visa holders who got stranded here due to the ongoing lockdown in India.

India extended the ongoing lockdown by two weeks from May 4 to contain the spread of the coronavirus that has affected nearly 40,000 people in the country.

Aggarwal said that a small number of the applications constitute those from pregnant women and other medical cases.

Since the online registration process was launched, the Consulate's website crashed several times due to the heavy rush of applicants wishing to register to fly back home.

The site has been working fine now though it took a lot of time for it to stabilise in the initial phase due to the heavy traffic, the counsel general said.

He said that the missions here have not yet received any information from the Indian government about the mode of transport of the stranded citizens, the prices of the tickets or how the COVID-19 test results of applicants would be assessed for their journey.

There are high-level discussions going on regarding these things, he said in the report.

Meanwhile, Norka (The Non Resident Keralites Affairs) said it has received a total of 398,000 applications from Keralites across the globe who wish to return home.

"Of which, the highest numbers are from the UAE. At least 175,423 applicants have signed up from the UAE," Norka said in an official statement on Saturday.

It also received 54,305 registrations from Saudi Arabia, 2,437 from the UK, 2,255 from the US, and 1,958 from Ukraine from those who wish to return to India, the Khaleej Times reported.

The coronavirus has infected 13,599 people and claimed 119 lives in the UAE, the Ministry of Health and Prevention said on Saturday.
