5-year-old boy mauled to death by pack of strays

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, Jan 14: Assuring depositors that their money was "100 per cent safe" with the bank, Sri Guru Raghavendra Sahakara Bank Chairman K Ramakrishna in Bengaluru on Monday said 62 loans had locked up Rs 300 crore of deposit.

"Your money is 100 per cent safe with Sri Guru Raghavendra Sahakara Bank. It's my responsibility," Ramakrishna said at Sri Guru Narasimha Kalyanamandira auditorium, to assure depositors.

He was addressing angry customers of the bank at a public hearing. Due to the 62 dud loans, the Reserve Bank of India (RBI) had restricted the lender from executing business, Ramakrishna said amid shouting by depositors. The RBI has limited withdrawals by depositors to Rs 35,000.

"The bank is saying I can't withdraw more than Rs 35,000. In case of our fixed deposit maturing, we will have to renew it as we can't encash it, " said Nagaraj M, 49, who has been dealing with the bank for the past six years.

To assuage customers, the call to an assistant commissioner of police by Bengaluru South MP Tejaswi Surya -- not present -- was relayed on loudspeaker live and the MP claimed that he had spoken to Finance Minister Nirmala Sitharaman to help the customers.

Ramakrishna said he would meet customers again on January 19 with all the details and numbers. Dramatic scenes and pandemonium ruled the auditorium before his arrival. Thousands of bank customers threatened to go en masse to the police station and file a case against Ramakrishna.

As he addressed the gathering in Kannada, hundreds of depositors shouted back at him seeking clarifications. At the auditorium, thousands of depositors earlier demanded the bank chairman's presence to clarify the matter.

The lender had invited depositors to the auditorium at 6 p.m. to update them on the bank's status, following a RBI directive restricting the bank from doing business with immediate effect.

"We want the bank's directors here," shouted a depositor from the stage. A handful of policemen were trying to control the crowd and bring order to the assembly. Many elderly and retired persons had arrived to know the fate of their savings. Several women were also present at the meeting.

"It was a good bank with only 0.5 per cent NPAs. Now we can't trust any bank. See what happened with the PMC Bank," said another customer.

Shankar Sharma, 38, an employee of a private company, said majority of depositors were senior citizens and retirees. "I don't have an account with the bank, but my mother, uncle, aunt have deposited money in it. I came for them, " said Sharma. He said many of the bank's 35,000 clientele deposited more than Rs 5 lakh, which had total deposits of Rs 1,600 crore. The bank started operations in 1999.

Ramakrishna was escorted away to safety by the police after his speech even as the depositors were screaming and agitating for justice.
