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.

If Owaisi compains for jds and bsp, he will lose the respect what we kannadigas have in him. He is being used by these parties only to divide muslim votes and alternatively support bjp. In case Owaisi did so, it will be very clear that he is hidden agent of bjp. If actually he needs betterment of muslims, he should keep away from Karnakataka elections. |this is our sincere advice to Mr. Owaisi otherwise we will support or respect him any more. Besides this if he comes to karnataka, i reqeust muslims to welcome him by rotten eggs and black flags. Let him understand that this is not Hyderabad. Why is he showing double standard? Why cant he stand in one boat. He should not try to be another Mir Jafar or Mir Qasim. I was a fan of him, but if he comes to karnataka on the hidden agenda of bjp, i will disrespect him for ever and will not consider him as a sympathisers of Muslims. He will do it for his own benefit. In every speech he speaks about unity in Muslims but he himself is going against it. I doubt he will keep on his popularity and may lose next election in his own constituency and AIMIM will also be thrown out. Hope Owaisi will understand the situation and take back his plan to visit karnataka to divide muslim votes.
Mr. Owaisi, try to follow one ideology. Dont spread your leg in two boats at the same time, you may fall down
He only denied the campaign offer before. Now again..
Double Standard guy, we know about you and we know about your dealing With BJP president Amith Shah close door meeting , do not try to fool Kanndaigas , we are very clear whom to vote ...........
Wonder land man from wonderland AIMIM looks not Indian degree, may be United Kingdom Degree after MIMIM this is Masters degree to the wonder Owaisi!!!!! any way he is the Gate way of "Devide and Rule" good money bai sabb, you divide or Sale no problem, we need our comission, he did in Uttarpradesh, Bihar now he came to Karnataka, no worries "Every Dog has its own day Bai sabb" I am sure Kannadians will not listen your stupidity
