NIA arrests Bhatkal man, two others deported from Dubai for alleged IS links

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 19: Karnataka Chief Minister B S Yediyurappa on Sunday said he has had detailed discussions with BJP National President Amit Shah on the cabinet expansion and that the exercise would be carried out after his return from Davos.

The Chief Minister told reporters before leaving for Davos to attend the World Economic Forum meet that he hoped his visit would help bring in large-scale investments to the state. "On cabinet expansion, I had detailed discussions for about half-an-hour (with Amit Shah on Saturday), got a good response... one or two days after I come from Davos, I will expand the cabinet. There are no stumbling blocks for it", Yediyurappa said.

He also rubbished media reports about a lack of clarity on the Ministry expansion. "It is not right... there are no issues", he said.

Asked whether he would travel to Delhi to meet Shah after returning from Davos, Yediyurappa merely said, "It is natural for me to meet Amit Shah." According to the Chief Minister's tour programme, he will be back in the city on January 24.

Yediyurappa, along with Union ministers Piyush Goyal and Mansukh Mandaviya, as well as Chief Ministers Amarinder Singh of Punjab and Kamal Nath of Madhya Pradesh, are among those expected to join over 100 Indian CEOs at Davos in the coming days for the WEF's 50th annual meeting.

Stating that he was leaving on a four day trip for Davos with an aim to bring investments to the state, he said interactions have been fixed with 38 industrialists and investors. "There is a large possibility of investments coming to the state from meetings during the WEF meet. I will assure industrialists and investors that the government will give all necessary facilities within our limits and also clear all the doubts that they have," the Chief Minister said. He said employment opportunities in Karnataka would increase due to all these efforts.

Claiming that the economic situation in Karnataka was stable despite the global economic slowdown, he said the state was also organising the Global Investors Meet in November to attract industries and create employment opportunities.

The delegation led by Yediyurappa includes Industries Minister Jagadish Shettar, Chief Secretary T M Vijaya Bhaskar and top officials of the state government. The Chief Minister, who was anxiously waiting for the high command's nod to expand his ministry amid intense lobbying by the aspirants, was keen on getting approval for it from Shah, but was asked to visit Delhi after returning from Davos, party sources said.

They also said that with J P Nadda all set to take over as BJP National President, he would have final discussions with Yediyurappa on the Ministry expansion exercise. S R Vishwanath, Political Secretary to the Chief Minister too said that Yediyurappa would go to Delhi after his return from Davos and immediately expand the Ministry.

He said the Chief Minister has been asked to hold discussions with Nadda, who is currently BJPs National Working President and finalise things.

As the Chief Minister has already made it clear that 11 of the disqualified JDS-Congress MLAs who got re-elected in the bypolls on BJP tickets will be made ministers, lobbying has been on in the party for the remaining ministerial berths. Currently, there are 18 Ministers, including the Chief Minister in the cabinet that has a sanctioned strength of 34.

However, with some reports that the high command may not be keen on making all the 11 re-elected legislators, whom Yediyurappa has given assurance, as Ministers, it remains to be seen how things turn out. Cabinet expansion will not be an easy task for the Chief Minister as he will have to strike a balance by accommodating the victorious disqualified legislators as promised and also make a place for old guards, upset at being "neglected" in the first round of the induction exercise.

He also has to give adequate representation to various castes and regions in his cabinet and also deal with the allocation of key portfolios. Also, disqualified legislators who lost on a BJP ticket during the bypolls like A H Vishwanath (Hunsur) openly expressing their ministerial aspirations has added to the Chief Minister's worry.

Bellari, Feb 23: Fringe outfit Sri Ram Sena leader Sanjeev Maradi said on Friday said that organization will reward Rs 10 lakh to the person who will 'eliminate' those who have raised "pro-Pakistan" slogans including Amulya who recently raised "Pakistan Zindabad" slogan at an anti-CAA protest in Bengaluru.

"We request both state and central government not to release them (Pro-Pakistan sloganeers) on bail. If they will be released Sri Ram Sena will eliminate them or will give a reward of Rupees 10 lakh to those who kill them," said Sanjeev Maradi.

"We condemn such slogans. This is like a virus. First, it happened in Jammu and Kashmir, then in JNU, then Mysore and then a student named Amulya raised pro Pakistan slogan in Bengaluru," he added.

A girl named Amulya raised 'Pakistan Zindabad' slogan on Thursday at an anti-CAA protest where AIMIM chief Asaduddin Owaisi was also invited.

Thereafter, a case was registered under Section 124A (Offence of sedition) of the Indian Penal Code against the student.

Meanwhile, Imran Pasha, the organizer of the anti-CAA protest said that Amulya was not invited to the event.

"We were the organizers of the event. At around 6:45 pm on Thursday, when I and Member of Parliament Asaduddin Owaisi were entering the stage area, we did not notice Amulya was present there. I did not invite her," Pasha told media.
