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, Apr 8: In another incident of health staff involved in coronavirus containment facing trouble, two ASHA workers were allegedly manhandled at Kudachi in Belagavi district in Karnataka on Tuesday while undertaking a survey following detection of four COVID-19 cases with Tablighi links in the area, police said.

The district authorities have intensified door-to-door survey in Kudachi after four people who had attended the Tablighi Jamat religious conference in New Delhi last month tested positive for coronavirus in nearby Raibagh.

“Today when two ASHA workers went to Kudachi, some miscreants snatched away their phones. We are investigating whether they were beaten up also,” a police officer investigating the matter told PTI.

A few days ago, four ASHA workers here were manhandled when they went for a door-to-door survey and police have arrested five people from a minority community. They have been remanded to judicial custody by a court.

Former prime minister H D Deve Gowda had on Monday condemned incidents of attacks on doctors and health department workers and sought protection for them.

Bengaluru, Jun 22: The Central Crime Branch (CCB) of Bengaluru Police has obtained the custody of an associate of gangster Ravi Pujari and is questioning him about his role in several cases against the gangster, the police said on Monday.

According to the police, Khan is convicted in the case related to the murder of a builder named Subba Rao in the year 2017. The accused has been identified as Yousuf Bacha Khan.

"Continuing the investigation of Ravi Poojary, CCB had obtained custody of Yousuf Bacha Khan, who is associate of Pujari. Khan was convicted in the Subba Rao murder case. He is being questioned about his role in other cases," Joint Commissioner of Police (Crime) Sandeep Patil said.

The CCB had recently filed two charge sheets against gangster Ravi Pujari in Shabnam developers double murder case and an extortion case.

Pujari, who was wanted in several cases including ones related to heinous crimes like murder and extortion, was extradited to Bengaluru earlier this year from Senegal.

The gangster, who parted ways with underworld don Chhota Rajan, had jumped bail after he was arrested in Senegal in 2019 and had escaped to South Africa, where he was involved in drug trafficking and extortion.

According to sources in the Indian intelligence, Ravi Pujari was hiding under the false identity of Anthony Fernandes, a Burkina Faso passport holder, in a remote village in South Africa.
