PM Modi launches foundation stone ceremony for first Hindu temple in Abu Dhabi

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 17: Karnataka Health Minister and BJP leader B Sriramulu on Friday claimed that Congress supports Social Democratic Party of India (SDPI) and Popular Front of India (PFI) to disturb peace in the state.

His statement came after the arrest of 6 SDPI supporters in connection with an attack on a BJP-RSS follower during a pro-CAA rally held in December last year.

"The Congress party 100 per cent supports SDPI and PFI. Whenever they do not get the power, they try to disturb the peace with the support of SDPI and PFI. I will propose in Karnataka Assembly session to ban these organisations in Karnataka. We will discuss this matter," Sriramulu told ANI.

"We had already demanded for the ban on these organisations in Karnataka when I was an MP. Shobha Karandlaje, Yediyurappa and I had met Rajnath Singh, the then Home Minister in Delhi and we had given a memorandum to ban SDPI and PFI," he added.

A case has been registered against arrested SDPI supporters under relevant Sections of the Indian Penal Code (IPC). Bengaluru Police is constituting a new Special Investigation Team (SIT) to handle this case.

"There were 6 people belonging to SDPI, who were here to carry out attacks on leaders supporting CAA. These people were being paid Rs 10,000 from their handlers to create ruckus here. Now this will be handled by the Anti-Terror unit," said Bhaskar Rao, Bengaluru Commissioner of Police.

Earlier today, Karnataka Minister Jagadish Shettar called for a ban on SDPI.

"SDPI always denies their involvement but it has been proved now. I welcome the police's action. Their organisation should be banned as they have always been involved in anti-social activities and government of India should take very serious note of this," Shettar told ANI here.
