Arvind Kejriwal's principal secretary, four others arrested in graft case

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.

Mangaluru, June 11: The Saudi Arabia based Expertise Contracting Company, which is repatriating its employees to India and other countries, today allocated around 90 seats of one of its chartered flights to Kannadigas stranded in Saudi Arabia. 

The Gulf Air flight took off with around 175 passengers on board from Dammam International Airport around noon local time. It is expected to land at Mangaluru International Airport at around 7 p.m. Indian time. 

In fact the company had chartered the flights only to repatriate its employees. However, due to the lack of special flights under Vande Bharati Mission, the company decided to help the other stranded Kannadigas in Saudi Arabia, who had approached Saudi Kannadigas Humanity Forum for help. 

A company official said that around 2,000 employees from various countries in the Indian subcontinent are being repatriated, of which 1,665 are Indians.  Already hundreds of them have reached India, and hundreds are still waiting for repatriation. 

“We are grateful to Expertise for allowing to travel in the flight which the company had chartered to repatriate its own employees,” said one of the passengers before boarding the flight at the airport.  

Director of Expertise, KS Shaikh said the 20-year-old Expertise group, one of the largest conglomerates in the GCC operating in petrochemical and heavy equipment sectors, has more than 10,000 employees and their family members in the Gulf, mainly in Jubail, one of the largest industrial cities.

Of these, the company has chosen over 2,000 employees for the covid-related repatriations considering various emergencies. He said 12 chartered flights have been engaged to carry out the repatriation exercise to the Indian subcontinent.

Mangaluru, Jun 2: The Karnataka Muzarai department, whose main income comes through temple and other religious places of worship, has incurred a loss of Rs 600 Crore in revenue during the lock-down, Minister for Muzrai Kota Srinivas Poojary said on Monday.

Addressing reporters here, he said the Kollur Sri Mookambika temple alone lost revenue of about Rs 14 crore it was earning during April and May.

Around 300 A and B grade temples under Muzrai (Hindu religious institutions and charitable endowments) department in the State lost around 35 per cent of their annual income, he said.
