Puttur: Rape attempt on student after SSLC exam by two relatives

Bengaluru, Feb 19: Playing down the simmering discontent among the disgruntled legislators who missed a cabinet berth again, Karnataka BJP on Tuesday denied any revolt brewing against Chief Minister B.S. Yediyurappa.

"An unsigned letter in Kannada circulating in the social media is bogus, as it was fabricated in the name of Santosh, a private secretary to Yediyurappa. No revolt is brewing against the Chief Minister," party spokesman G. Madhusudhana told news agency here.

In the second cabinet expansion on February 6, only 10 newly-elected legislators, who defected from the Congress and the Janata Dal-Secular (JD-S) in July, were inducted, leaving the party's many aspiring lawmakers miffed.

"The talk of about 20 loyal MLAs ganging up against Yediyurappa is a speculation as rumour mills are working overtime. No rebellion is brewing against the Chief Minister," asserted the official.

On the charge that Yediyurappa's younger son B.Y. Vijayandra was acting like a 'super or de facto CM' and medalling in the state administration, Madhusudhana said the latter was only assisting his father in party activities as he was also a party worker.

"As Yediyurappa is 76 years old and ageing, Vijayandra is helping his father in party affairs so that he (Chief Minister) could be free to attend to administration," Madhusudhana said.

Yediyurappa's elder son B.Y. Raghavendra is a three-time BJP Lok Sabha member from Shimoga in the state's Malnad area.

With six cabinet posts vacant in the 34-member ministry, many legislators, including eight-time MLA Umesh Katti, are upset that they have not been rewarded for their loyalty to the party even six months after the BJP returned to power again in the southern state.

On the purported meeting of about 20 BJP MLAs at the residence of state Industries Minister Jagadish Shettar here on Monday, Madhusudhana said it was a "get-together" as they were all in Bengaluru again to attend the budget session of the state legislature which began on Monday.

"There is no crisis in the party. Our government is stable and will complete the remaining three-year term in office till May 2023," he added.

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.
