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, April 7: Karnataka government on Monday allowed bakeries and related product food units in the state to open and function with minimum staff amid a coronavirus nation-wide lockdown.

Bengaluru, Jul 24: A government doctor who was turned away by three private hospitals because he could not produce a coronavirus test result passed away today in Bengaluru. Dr Manjunath, who was a frontline COVID-19 doctor, was allegedly turned away by hospitals when he was extremely ill and struggling to breathe.

Dr Manjunath worked in the state Health and Family Welfare department and was based in Ramanagara district, around 50 km from Bengaluru.

D Randeep, a Special Officer with the Bengaluru municipal body BBMP, said that the hospitals that had refused to admit Dr Manjunath would be reported to the health department.

In June-end, Dr Manjunath went to Rajashekhar Hospital in JP Nagar, BGS Global Hospital in Kengeri and Sagar hospital in Kumaraswamy Layout. All three demanded to see his COVID-19 test result but those were still not in at the time, according to his family. His brother-in-law Nagendra is also a doctor with BBMP and in charge of allotting hospital beds, yet he was completely helpless when it came to his own relative.

He was finally admitted to Sagar hospital on June 25 when his family sat in protest on the footpath outside the Dayananda Sagar campus. He was placed on ventilator and later shifted to the Bangalore Medical College and Research Institute, where he died earlier today. The hospital says Dr Manjunath was discharged on July 9 because he wanted plasma therapy.

Six members of his family, including a 14-year-old, tested COVID-19 positive. Most of them have recovered.

Bengaluru has seen several cases of patients being turned away from hospitals in the city. Hospitals say they need Covid test results to know whether to admit patients in the coronavirus ICU or in the general section and to understand treatment protocol.

Mr Randeep said hospitals have been instructed to admit patients even without such a certificate. Notices have been sent to hospitals that fail to comply. The OPD of two private hospitals was sealed for 48 hours when they refused to admit a patient.
