Bengaluru, Mar 13: India has registered the first confirmed case of death due to novel coronavirus. A 76-year-old man from Karnataka's Kalaburgi who passed away recently has been tested positive for Covid-19.

The doctors had suspected that the man had coronavirus, however, the test had not confirmed it.

In an official notification, a senior health official in Karnataka government Dr Suresh Shastri said that the lab test has confirmed that the deceased man had Covid-19.

"The 76-year-old man from Kalburgi who passed away and was a suspected COVID 19 patient has been confirmed for COVID 19. The necessary contact tracing, isolation and other measures as per protocol are being carried out. Telangana government has also been informed since he went to a private hospital there," Dr Suresh Shastri said.

The same information was also shared by Karnataka health minister B Sriramulu.

A senior Union health ministry official said in New Delhi that the death of the man had visited Saudi Arabia from January 29 to February 29. The official said the man had reached in Hyderabad on February 29 and went to Kalaburagi in Karnataka.

State Joint Director (Communicable Diseases) BG Prakash Kumar said all protocols were followed for disposal of the body.

"The body is disinfected completely and disposed of as per the Government of India guidelines," he added when asked to elaborate on the protocols.

He said the Telangana government has also been informed as the man had gone to a private hospital in Hyderabad earlier.

While announcing the death of the man on Tuesday, the state authorities had said the exact cause his death was being ascertained.

According to the Union health ministry official, "While he was asymptomatic on his return (from Saudi Arabia), he developed symptoms of fever and cough on 6th March. One private doctor visited him at his home and treated him there."

"On 9th March, the symptoms got aggravated and he was shifted to a private hospital in Kalaburagi. In this private hospital, he was provisionally diagnosed as 'mid-zone viral pneumonia' and 'suspected Covid-19'," the official said.

"The sample was collected on March 9... Without waiting for the test results, the attendees insisted and the patient was discharged against medical advice and the attendees took him to a private hospital in Hyderabad," the official said.

The patient was admitted to a private hospital in Hyderabad and treated. He died on Tuesday when he was being brought back to the Gulbarga Institute of Medical Sciences (GIMS) in Kalaburagi.

Apart from the deceased, Karnataka has confirmed five other positive cases of the novel coronavirus. The fifth case, confirmed on Thursday is of a 26-year-old man who recently returned from Greece.

The patient has been admitted and isolated at a hospital and his condition is stable, a department media bulletin said.

The day also saw the education department declaring summer holidays for students from kindergarten to class six and study leave for higher classes in the city as a precautionary measure.

Bengaluru, Apr 11: Karnataka Congress chief D K Shivakumar on Saturda said that he was hopeful that the Karnataka Chief Minister would take stern action against BJP MLA M Jayaram--who was on Friday seen celebrating his birthday with several villagers in Gubbi taluk in Tumkur, in violation of social isolation measures and nationwide lockdown to fight the coronavirus outbreak.

"I am sure that the Chief Minister will take action on all these types of activities. We have already petitioned the DGP. Suo moto case should be registered immediately," the Karnataka Congress Chief told media.

Speaking about the video conference meeting that Congress President Sonia Gandhi held with all Pradesh Congress Committee (PCC) presidents via video conference, he said: "She has given us directions that the party has to play its own role. She said that the party needs to be very active, apart from the government."

With regards to the farmer's struggles due to the national lockdown, the Karnataka Congress Chief said that the farmers are in a 'very grim situation'. "I appeal to all the people of Karnataka that we should go to the fields and discuss with farmers and buy the materials. Let us purchase their fruits and vegetables and distribute them at the village level."

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.
