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.

I dont understand, why media giving attention to this rubbish speech.. He just wanted media attention. and also he wanted to thrill his followers..
Nalin Kumar Kateel is no. 1 terrorist. Once he told, he wanted to burn entire Mangalore.
Shakha trained bhakt ! Modi & Shah are very happy on his comment on CM. Nalin Don't worry you are eligible represent educated Mangalorean (?) in forth coming Parliament election -2019.
This kateel is delivering an election speech or mocking himself?
An uneducated goon who threatened to set entire Dakshina Kannada district on fire is a desh bhakt. And a farmers’ leader turned politician who upheld the concept of Kalnaya Rajya is a terrorist. What a joke.
Katilanna.. First learn language. The meaning of Sultan is King. You are hailing him as king. King will be terrorists for only terrorists.
I think politics of this region is a curse. There is no boundries to the wild allegation and lies that these politicians utter. I think we have to play back some of his terrorism speeches including burning of DK speech.
The only way we can stop BJP getting back to power in Karnataka is to switch to ballot system.
What they think they can fool all Kannadigas, as they did in North East, UP.
Unfortunately the people in that regions are very innocent. They don’t understand how they are being fooled by their leaders specially Modi and Amit Shah.
Now their own people are fed up of them. Many secular leaders left the BJP and jointed Congress.
Kateel is very lucky to be a MP who really does not deserve to be Grama Panchayat member.
The cleanest CM is Siddaramiah, in the recent generation, like very few CM s we had in the past like Nijalingappa, Kadidal Manjappa. He never indulged in single bribery or corruption.
He is Very straight and strong leader, who has always worry for the people. But our stupid opposition want to destroy him for their selfishness at the cost suffering of poor people.
May God almighty help our people to understand the fact and elect the best leaders.
