Install Dr Rajkumar’s statue in parliament, give him ‘Bharat Ratna’: Vatal Nagaraj

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 18: Bringing a major change in the  administration of Bengaluru, which has emerged as a Covid-19 hotspot, the state government on Saturday transferred B H Anil Kumar out of the BBMP and brought N Manjunath Prasad to take his place. 

Manjunath Prasad, who headed the Bruhat Bengaluru Mahanagara Palike (BBMP) before being replaced by Kumar, will take over with immediate effect. The government has also placed him in concurrent charge of the Revenue Department as well as the Disaster Management, Bhoomi and UPOR.

Kumar, an Additional Chief Secretary, has been put in a place where earlier a secretary was posted. He now heads the Department of Public Enterprises. The posting would have brought him two spots down had it not been for the government upgrading it to the level of additional chief secretary. 

Anil Kumar, who was earlier praised for his work to contain the coronavirus pandemic, had faced criticism by the High Court of Karnataka for the BBMP's failure to help people in containment zones as well as other issues on the spread of the pandemic. 

Sources in the government said, pressure has been building up against Anil Kumar over the last two months after most of the Bengaluru MLAs complained to the chief minister's office.

"No MLA backed him. Everyone had a problem," a source said. 

Things came to the head with regard to a Rs 436 crore project given to KRIDL. "The issue reached the chief minister's office as all the MLAs took an issue with the way the project was awarded," a source said. 

Another source said that Kumar came under fire after a central team flagged the issue of failing Covid-19 surveillance measures in Bengaluru. The central team's criticism, it is widely believed in the government, came as the last straw.
