No Hajj flights from Mangaluru Airport from 2018?

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mangaluru, Jun 29: A hospital set up in 1848 in the Port City has to remain closed till July 5 as majority of the Doctors and Staff at Lady Goschen Government Hospital are quarantined after coming in contact with a COVID-19 infected person.

Hospital Medical Superintendent said that both in-patient and out-patient wings of the hospital will remain closed till July 5 as there is a need to fumigate and sanitise all the departments of the hospital. Patients for treatment under 'Ayushman Bharat – Arogya Karnataka' scheme will be sent to private medical colleges with the referral card from the hospital. The hospital will start functioning normally from July 6.

The Lady Goschen Government Hospital, earlier known as the maternity Hospital, is the oldest hospital in the district and dates back to 1848.

Dubai, Jul 8: The Directorate General of Civil Aviation (DGCA) has revoked landing permits issued to UAE-based private jets flying Indian expats who are willing to fly back to UAE. With this the operation of private jets from India to the UAE has stopped.

The development comes days after DGCA stopped UAE airlines from chartering repatriation flights to India. 

The DGCA’s decision has come as a huge disappointment for desperate expats who are trying every means possible to return to the UAE, and were shelling out up to Dh15,000 per ticket.
 
All charter flights were operating with the appropriate permissions and clearances for the specific mission, route and destination, said the charterers.

DC Aviation Al-Futtaim, the only integrated VIP handling and hangar facility in DWC, said in an official statement: "As a result of the DGCA suspension of flights into India, our Challenger 604 aircraft which was scheduled to land in Dubai today has been affected."

Afi Ahmed, managing director of Smart Travels, said he has received news from official sources that all approvals for operation of private jets have been barred until July 10.

"Even the flights that had been given approvals stand cancelled. Some flights organised on July 9 have also been grounded," said Ahmed, who was also stranded in Kochi, Kerala, till July 4 but returned home in the UAE on-board Global 6,000, the largest business jet, organised by a Dubai-based aviation company.

Ganesh Rayapudi, a UAE-based businessman who has been trying to organise flights from India to UAE, said: "The government has kept on hold all charters. At least 52 passengers were desperately waiting to come back from Hyderabad on these flights and were willing to collectively cough up Dh400,000."

He added: "I agree that it is unfair to those who cannot afford these prices. However, UAE residents have commitments here; they were tired of waiting and willing to go any lengths, including taking the expensive route."

On July 3, India's DGCA announced via an official circular that scheduled international flights will remain suspended till month-end and only those on a case-to-case basis will be allowed to operate. These flights were suspended on March 22 due to the ongoing pandemic.
