Mangaluru: II PU science student found hanging in Thokkottu

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.

New Delhi, Feb 7: The Supreme Court on Friday issued a notice to the Central government on a plea challenging the Constitutional validity of the Citizenship Amendment Act (CAA) and effective implementation of the Assam Accord.

A bench of Chief Justice of India (CJI) SA Bobde also sought Centre's response on the plea filed by Assam Social Justice Forum.

The petition sought appropriate directions for taking effective steps for the implementation of Assam Accord, 1985 in letter and spirit and for conservation and preservation of the of a distinct culture, heritage and traditions of the indigenous people of Assam.

The Assam Accord, 1985, had fixed March 24, 1971, as the cut-off date for deportation of all illegal immigrants irrespective of their religion.

The Bench also sought Centre's response on another fresh batch of pleas challenging CAA and tagged them along with other petitions pending in the matter.

One of the petitions, filed by the Association of Advocates from Maharashtra among others, sought to declare the Citizenship Amendment Act as discriminatory, arbitrary, and illegal and consequently set aside the impugned act as ultra-vires the Constitution of India.

On the other hand, over a hundred petitions have been filed in the apex court, for and against the amended citizenship law, which is facing opposition and protests across the country.

CAA grants citizenship to Hindus, Sikhs, Buddhists, Jains, Parsis and Christians who fled religious persecution in Afghanistan, Bangladesh, and Pakistan and took refuge in India on or before December 31, 2014.

Bengaluru, Feb 28: Historian S. Shettar, 85, breathed his last early on February 28 in Bengaluru. He was suffering from respiratory problems and was hospitalised for over a week.

Shettar was known for his multi-disciplinary work, encompassing linguistics, epigraphy, anthropology, the study of religions and art history. He had extensively worked on the Jain practice of ritual death in Karnataka and Asoka edicts. He had studied and compiled early edicts in Kannada and worked extensively on the growth of Kannada language down the ages.

Born in 1935 at Hampasagara, Ballari district, he went on to study at Cambridge University and started his career as a Professor of History at Karnatak University, Dharwad, his alma mater. He later headed the National Museum Institute of the History of Art, Conservation and Museology in 1978 and Indian Council for Historical Research in 1996. He was also a visiting professor at the National Institute of Advanced Studies, Bengaluru.

He was a bilingual historian who wrote in English for most of his career, but started writing in Kannada in later years. In the last two decades, he developed a keen interest in linguistics and wrote multiple books on classical Kannada and Prakrit. His 2007 book “Shangam Tamilagam” is considered a seminal work in the study of the early period of Dravidian languages. It won him Bhasha Samman from Central Sahitya Akademi. He later wrote two works on Halegannada, classical Kannada. His most recent work was “Prakrita Jagadvalaya” in 2018.
