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.

Bengaluru, Jul 16: Rattled by the spurt in Covid-19 positive cases, a Karnataka minister on Wednesday said only god would save the people from coronavirus pandemic.

"Only god has to save us from the virus or the people should be made aware of the infection so that they wear mask and maintain social distancing," state Health Minister B Sriramulu told reporters in Chitradurga, 205-km northwest of Bengaluru.

Noting that the infection does not differentiate between rich and poor, police, doctors, politicians or legislators, Sriramulu said the communicable disease could rise to alarming level in the ensuing two months, as the cases were rising daily the world over.

"Who can control coronavirus? In the present situation, only god has to save us. Otherwise, the people should become aware of its (virus) consequences. If we have made mistakes, we are ready to face punishment for them," said Sriramulu, who is the ruling BJP's legislator from the Molakalmuru reserved assembly segment in the district.

Refuting the opposition Congress charge that the cases were rising in the state due to negligence by ministers, officials and legislators, Sriramulu said Karnataka was performing better than other states till the cases began to steadily rise since unlock started and the people were moving in violation of the guidelines.

A record 3,176 cases were reported from across the southern state during the day, taking the Covid tally to a whopping 47,253, including 27,853 active cases after 18,466 were discharged, with 1,076 during the day, while 928 succumbed to the virus, with 87 in the last 24 hours.

In Bengaluru, which is under 9-day lockdown since Tuesday night till July 22 morning, 1,975 positive cases were registered, taking its tally to 22,944, including 17,051 active after 5,455 were discharged so far, with 463 during the day, while 437 died of the infection, with 60 in the last 24 hours.
