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.

Mangaluru, Jun 23: An elderly person, who was undergoing treatment for covid-19 in Mangaluru, breathed his last on today. 

The victim, identified by number P-6282, was a 70-year-old man. He had returned from Bengaluru on June 7. 

He was suffering asthma and pneumonia. He had Severe Acute Respiratory Infection (SARI) symptoms and was hence admitted to the designated covid-19 hospital in Mangaluru on June 12. 

His condition continued to worsen and today he breathed his last, sources said.

With this the total number the deaths of covid-19 patients in Dakshina Kannada district mounted to 9.

Bengaluru, Apr 7: The Karnataka Government indicated today that it is too early to take a call now on lifting the nation-wide lockdown but said it’s in favour of its extension in COVID-19 hotspots in the country by at least an additional two weeks.

“We need to see for another few days before taking final call,” Medical Education Minister Sudhakar K, who is in-charge of all matters related to COVID-19, told news agency Press Trust of India when asked if the State is in favour of the rollback after the 21-day period ends on April 14.

The minister opined that the decision on its withdrawal should be based on the COVID-19 pandemic situation at the time in terms of number of cases and response to the outbreak.

When the lockdown is lifted, it has to be in a staggered and phased manner, and not at one go, Mr Sudhakar stressed.

“Where there are red alerts and zones, those zones, in my opinion, should continue to be in a lockdown situation at least for two weeks…till this month-end, I will request them (the Centre) to do this,” he said.

The Telananga Chief Minister K Chandrasekhar Rao on Monday appealed to the Prime Minister Narendra Modi to extend the 21-day national lockdown imposed to contain COVID-19 outbreak beyond April 14, saying it was essential to save lives.

Mr Sudhakar said the Karnataka government is facing financial challenges because of drastic fall in revenues due to the lockdown, adding, it would take “tough decisions” to cut expenditure.

The Finance Department is in the process of evaluating the state’s fiscal position.

“Finance department is gathering information…what is the need now, what should be the overall expenditure, how much we can save; financial support for unorganised and organised sector, along with stimulus to other sectors, we have to see where we stand financially,” the minister said.

“Based on that, we have to take certain steps for sure because after all the government runs on the exchequer money. Once the exchequer is stopped because of lockdown, we are not getting GST, no motor vehicle tax. No tax money is coming.”

Government also has to run right? he said.

He said commitment and obligations with regard to paying interest on loans taken at the national and international level would have to be met.

“So, there are some financial constraints, and financial challenges before the government. The Government will take tough decisions only after studying the entire finance (position of the State).”

The Telangana government last week announced pay cut for government employees.

The Union Cabinet on Monday approved a 30 per cent cut in salaries of all Members of Parliament and a two-year suspension of the MP Local Area Development (MPLAD) scheme.
