Karnataka CM Siddaramaiah's son Rakesh, 39, dies in Belgium hospital

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, Mar 27: A 65-year-old coronavirus patient who died in Karnataka this morning after apparently contracting the infection on a train ride has raised concern about community transmission of the highly contagious disease.
The man, the 60th coronavirus patient in Karnataka, died in Tumakuru. It is not known for certain how he caught the virus. The Karnataka Health Department has posted a notice on Twitter asking whoever travelled with him on train to come forward.

He had no history of recent foreign travel but had apparently traveled to Delhi on March 5 by Sampark Kranti Express and returned on March 11.

On March 7, he arrived at Delhi's Nizamuddin station and participated in an event at Jamia Masjid.

The man took a train back on March 11 and arrived at Yeshwantpur in Bengaluru. From there, he took a bus on March 14 to his hometown Sira.

He first showed symptoms of COVID-19 on March 18 and was taken to a private hospital. He was sent home with medicines but his condition worsened.

On March 23, he was admitted to a district hospital, but checked himself out against all advice and went to a private hospital. When his health showed signs of deterioration, he was again sent to the district hospital, where he tested positive for coronavirus yesterday. He died around 10.30 am today.

The health department has since traced 24 people who came in direct contact with him and are so, in the high-risk category. Thirteen are in hospital and eight have tested negative.

"All passengers who had travelled with him on the train are being traced," K Rakesh Kumar, Deputy Commissioner, Tumakuru, was quoted as telling news agency ANI.

A 70-year old woman and a 76-year old man had died of coronavirus or COVID-19 earlier in Karnataka.

India has over 700 coronavirus cases, including 17 deaths.

Kasaragod, Jul 8: A 48-year-old man, who died on Tuesday, has tested positive for COVID-19 on Wednesday.

A native of nearby Mogral Puthur in Kasaragod district, Abdul Rahmn was running a business in Karnataka’s Hubli since long time.

He had recently returned to his hometown from Karnataka through Talapady border on the outskirts of Mangaluru.

Sources said, despite the man having acute fever, the authorities at the Talapady border not only took any action including informing the concerned, but allowed him to cross over the border in a vehicle.

He was rushed to Kasargod General Hospital soon after returning. Those who had accompanied him from Karnataka to Kerala are now under ouarantine.
