Patient sings as docs remove tumour from his brain at Thumbay Hospital

Mangaluru, Jul 22: As many as 184 people from Karnataka stranded in UAE arrived at Mangalore International Airport.

According to sources, the chartered flight, which landed on Tuesday night, was arranged by the UAE Karnataka Cultural Foundation and Beary Cultural Foundation for Kannadigas who had been stranded following the lockdown and also those who had lost their employment.

A team of officials with Puttur Assistant Commissioner Yathish Ullal and Horticulture Department Assistant Director Praveen who were in charge of quarantine facilities for international passengers verified the documents and sent them for institutional quarantine.

Of the 184 passengers, 141 had remained quarantined in Mangaluru while 42 left for Udupi and one to Honnavara in Uttara Kannada, said sources.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Is it highly impossible to have flights to Mangaluru under Vande Bharat Mission to repatriate the stranded Mangalureans in Saudi Arabia and other Gulf countries? The present mood of the govt seems so are more politics and less actions are seen. 

Amidst covid-19 lockdown, thousands of people from Mangaluru and surrounding areas are stranded in Saudi Arabia and other Gulf countries. They include visitors, job redundants, people who need immediate medical attention, senior citizens, pregnant women, students and people who are eager to visit their ailing family members, especially aged parents back at home. They are all stuck over there seemingly with hopelessness.

It's reported that around Karnataka NRIs (KNRIs) have registered their names under the Mission in the Indian Embassy in Riyadh alone. A majority among them are apparently from coastal districts of Karnataka who are eagerly waiting for the flights to Mangaluru. 

The promises of elected representatives including MLAs, MPs, state and central ministers have remained unfulfilled so far. Now, things are being thrown from politicians to politicians and from politicians to the district authorities and vice versa. It's said that without proper quarantine facility in the district, the repatriation flights can't be approved to Mangaluru. 

Rumours are doing rounds that the hotels in Mangaluru are not ready to facilitate for the KNRIs quarantines; the hoteliers collectively snubbed the instruction of the district authorities. Now, they are, as informed, persuading the hoteliers to allow for the quarantine facility. 

If the hoteliers are stubborn to follow the instructions of the district administration, then why the authorities are not taking action against them under relevant statutory procedure including the revocation/cancellation of their licenses? Are they above the law or govt? For whom the authorities are waiting for? These questions are now being asked by the KNRIs and others. 

Considering this condition, the central ministers and MPs are simply giving evasive answers without any forward thinking. Each one is simply uttering the same dialogue "no quarantine; no flights to Mangaluru". 

A few KNRI businessmen in Saudi Arabia have already chartered flights to transport their stranded employees and others to Mangaluru with the approval of the govt of India. But, the inconsolable thing is that the govt didn't arrange this simple thing that too with the expense of the travellers. 

The people-especially then distressed NRIs still remember late prime minister V P Singh and then external affairs minister I K Gujral for the repatriation of the NRIs during 1990s Gulf war. Everything was free of cost and immediate special flights were arranged to airlift the NRIs in the affected countries. 

Now both Karnataka and India are ruled by the BJP. Then why the non resident Kannadigas, especially those in Saudi Arabia, are direly neglected at this point in time?. Why it's highly impossible for the govts to do this simple job for the KNRIs?  The NRIs are always big assets to the govt. Also, the KNRIs remit billions of rupees to the state in the form of foreign exchange. But, they are now simply ignored. The state govt should immediately look into this dire situation of the Kannadigas in Saudi Arabia and act immediately to schedule special flights to Mangaluru from Saudi Arabia.
