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.

This attack on Karnataka by BJP. Why did not they raid houses of BJP leaders who have become rich after BJP came to power. Reddy brothers are roaming freely and had lavesh wedding of their daughter. IT department are sleeping
Timing is good!!. Each one repeats same in cycle and then they may stop doing corruption. But Indian political population is a strange one and may start bribing each other! Congress also did all kind of tactics! Timing of investigation of corrupt DMK - daughter!
How can congress explain recovery of 10.5 crores cash from the minister's residence?Is it not embarrassing for congress leaders who called the raid witch - hunt?
What does BJP say about corruption of their own leaders. How many raids were given on the corrupt leaders of BJP. There are not hundred but thousand cases of corruption of BJP leaders. Recently in Chhatishgarh, one minister Brijmohan Aggarwal has encroached the government land. A few days ago Chief of Kerala BJP was caught for taking bribe of Rs 6 crores. After demonetization maximum black money was recovered from these BJP leaders. Before demonetization, dubious land deals were executed with their black money as they know fully that demonetization was to be declared by their party.. Black money was recovered from the BJP leader in Punjab as well from Madhya Pradesh leader. Who is funding Amit Shah who is roaming using chartered planes from one place t0 another place. What were the sources of funds during elections either for the Centre or for the states. Admitted Congress is corrupt but BJP is the most corrupt party in India.Wherefrom they got 15 crores to purchase MLAs.
All corrupt politicians are the feathers of the same bird. All are corrupt whether in the ruling party or in the opposition. Some of them are pro industrial and getting unaccountable money to be spent on their rival parties to let down. If any leader is corrupt and facing trial in the court, they either try to purchase the sitting judges or transfer them on the name of promotion. These tactics have been used by Modi Government in Gujarat to have clean chits in Godhara riots.The enquiry commission was appointed to enquire about who were behind the killings of innocent Sikhs, one Mishra was purchased by the Congress party and he was taken in Rajya Sabha.These commission heads are corrupt and working as per directions of the ruling party. How one can get justice. In India justice is denied to poor, downtrodden and minorities. These political parties have cleverly expert to change the facts into lies. They are expert to purchase and threaten others who are disagreed with them
How can there be black money? Demonetisation was supposed to eradicate it.
He's questioning the time, he's not questioning all that money that's been
seized!
