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, May 6: Amidst preparation for the paid evacuation of Indians stuck in Gulf countries amidst coronavirus lockdown, the central government has announced that it would only do a medical screening of the passengers before the flight and only asymptomatic persons would be allowed to travel.

Each passenger will have to fill a self-reporting form to be presented at the health and immigration counter at their destination.

The passengers are required to state whether they are suffering from fever, cough, diabetes or any respiratory disease. This form is similar to the one filled by passengers landing in India during the early days of the COVID-19 outbreak.

As per the announcement by the government, returnees would undergo COVID-19 once they complete 14-day quarantine in a hospital or government –arranged institution on a payment basis.

However, the form asks the applicants to keep themselves isolated at home for 28 days unless they develop any symptoms such as fever and cough.

During the journey, they will have to follow the protocols such as those issued by the Health Ministry and the Civil Aviation Ministry. Applicants from the UAE are yet to receive instructions on these.

On reaching the destination, passengers will have to register on the Arogya Setu app, India’s mobile application for COVID-19 surveillance.

No physical distancing!

Air India Express (AIE) which is set to operate the first two flights to Kerala on Thursday will operate its Boeing 737-800 flights, with a seating capacity of 186 economy class seats.

With nine seats reserved for isolation, only 177 passengers would be flown, sources said.

While most of the UAE flights in the first week will be operated by the AIE, Air India will operate two of its Dreamliner aircraft with a seating capacity of 256 seats. These flights would also reserve some seats for isolation.

However, the plan has made it clear that the Indian government will not be following the rules of physical distancing to prevent the spread of coronavirus in the repatriation flights.

Several people, including the Chief Minister of Kerala Pinarayi Vijayan, expressed concern over flying passengers, who will not be tested for COVID-19, without observing physical distancing.
