Number of NYF participants grows beyond expectations'

Bengaluru, May 14: Reformed underworld don Muthappa Rai, who was battling cancer for the past year, was said to be in a critical condition at Manipal Hospital in Bengaluru, late Wednesday night. Doctors said he was on life-support at the time of going to press. Rai (68), realtor, entrepreneur and founder of pro-Kannada organisation Jaya Karnataka, had retired from public life after he was diagnosed with cancer. He was part of an ongoing investigation into gangster Ravi Pujari, who was extradited from Senegal recently.

Born in Puttur into a Bunt family, he started out as a bank employee in Bengaluru, and later ran a live band restaurant. In 1994, he was shot in a Bengaluru court by a man dressed as a lawyer, after which he was bedridden for a couple of years.

Rai Moved to Dubai in 1996. He was deported from the UAE to India in 2002, and was arrested in Bengaluru when HT Sangliana was the police commissioner. Both Rai and Pujari had allegedly been associated with underworld don Dawood Ibrahim.

Bengaluru, Feb 25: Infosys is all set to announce a cyber defence centre in Indianapolis to complement its technology and innovation centre inaugurated early last year.

This will be Infosys' seventh global cyber defence centre. According to its recent cybersecurity report titled 'Assuring Digital Trust,' 83 per cent of executives view cybersecurity as critical, yet 67 per cent are still struggling to have security embedded.

The cyber defence centre will provide end-to-end, real-time, 24x7 cyber security monitoring and protection services to support and guide American businesses in their digital transformation journey, it said.

The facility is dedicated and organised to prevent, detect, assess and respond to cybersecurity threats and breaches.

Client environment will be monitored round the clock, adopting a follow-the-sun model to deliver services like 24x7 security monitoring, management and remediation, threat hunting, security analytics, incident discovery and response, compliance reporting and malware analysis.

Vishal Salvi, Chief Information Security Officer and Head of Cyber Security Practice at Infosys, said the cyber defence centre is staffed with expert security analysts with niche skills around threat research and intelligence gathering to deliver best-in-class services to customers.

"Additionally, advanced data analytics and machine learning models are deployed to detect zero-day threats by unknown threat actors. This supports our commitment to helping our customers build a resilient cybersecurity programme that operates at scale while increasing operational efficiency and reducing costs," he said in a statement.

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.
