Govt failed to get FAC okay for Yettinahole project: Petitioner

The deadly coronavirus that entered India while there was still nip in the air has beaten rising mercury, humid conditions, unique Indian genome and has entered monsoon season with more potency as fresh cases are only breaking all records in the country.

India recorded a single-day spike of record 24,850 new coronavirus cases on Sunday, taking its total tally to 6.73 lakh corona-positive cases.

Top Indian microbiologists were hopeful in March that after the 21-day lockdown, as summer approaches, the rise in temperature would play an important role in preventing the drastic spread of COVID-19 virus in India.

Several virologists hinted that by June this year, the impact of COVID-19 would be less than what it appeared in March-April.

The claims have fallen flat as the virus is mutating fast, becoming more potent than ever.

According to experts, the novel coronavirus is a new virus whose seasonality and response to hot humid weather was never fully understood.

"The theory was based on the fact that high temperatures can kill the virus as in sterilisation techniques used in healthcare. But these are controlled environment conditions. There are many other factors besides temperature, humidity which influence the transmission rate among humans," Dr Anu Gupta, Head, Microbiologist and Infection Control, Fortis Escorts Heart Institute, told IANS.

There is no built-up immunity to COVID-19 in humans.

"Also, asymptomatic people might be passing it to many others unknowingly. New viruses tend not to follow the seasonal trend in their first year," Gupta emphasized.

Globally, as several countries are now experiencing hot weather, the World Health Organization (WHO) reported a record hike in the number of coronavirus cases, with the total rising by 2,12,326 in 24 hours in the highest single-day increase since COVID-19 broke out.

So far over 11 million people worldwide have tested positive for the disease which has led to over 5,25,000 deaths, according to data from Johns Hopkins University. The US remained the worst-hit country with over 28 lakh cases, followed by Brazil with 15.8 lakh.

According to Sandeep Nayar, Senior Consultant and HOD, Respiratory Medicine, Allergy & Sleep Disorders, BLK Super Speciality Hospital in New Delhi, whether temperature plays a role in COVID-19 infection is highly debated.

One school of thought said in the tropical regions of South Asia, the virus might not thrive longer.

"On the other hand, another school of thought has found that novel Coronavirus can survive in a hot and humid environment and tropical climate does not make a difference to the virus. According to them, this is what distinguishes the novel coronavirus from other common viruses, which usually wane in hot weather," stressed Nayar.

Not much has been studied in the past and no definite treatment or vaccine is available to date.

"Every day, new properties and manifestation of the disease come up. As of now, the only way to prevent this monster is by taking appropriate precautions. Hand hygiene, social distancing, cough etiquette and face masks definitely reduce spread of COVID-19 infection," Nayar told IANS.

Not just top Indian health experts, even Indian-American scientists had this theory in mind that sunshine and summer may ebb the spread of the coronavirus.

Ravi Godse, Director of Discharge Planning, UPMC Shadyside Pennsylvania in the US told IANS in April: "In the summer, the humidity can go up as well, meaning more water drops in the air. If the air is saturated with water and somebody sneezes virus droplets into such air, it is likely that the droplets will fall to the ground quicker, making them less infectious. So the short answer is yes, summer/sunshine could be bettera.

According to Dr Puneet Khanna, Head of Respiratory Medicine and Pulmonology, Manipal Hospital, Delhi, COVID-19 death rates are not too different in tropical countries but since the disease affected them late it was yet to show its peak in these areas.

"The virus can survive well in hot and humid countries and this is proven now," he stressed.

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.
