Will appear before police in ponzi case: Janardhana Reddy

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, July 17: The government of Karnataka has decided to issue caste and income certificates to Brahmins in the state to reduce the socio-economic inequality faced by the community.

“A notification has been issued to tehsildars in all 30 districts to issue caste and income certificates to Brahmins so that they can also benefit from the government schemes and scholarships,” a Revenue Department official told said.

The notification comes a month after the Karnataka State Brahmin Development Board on June 10 appealed to Chief Minister B.S. Yediyurappa to issue the certificates to the traditionally dominant community, which accounts for 3 per cent of the 7 crore state population.

“Though Brahmins are in ‘minority’ in terms of their population across the state, they need caste and income certificates to benefit from the welfare schemes meant for the economic weaker sections such as SC, ST and OBC groups,” the official said.

The board was set up in March 2019 as a state-run company with Rs 5 crore authorised capital and Rs 5 crore equity and is registered with the Registrar of Companies.

The notification was issued to the local bodies and taluk offices after several members of the community complained to state Revenue Minister R. Ashoka that they were unable to benefit from the welfare schemes in the absence of the certificates.

The certificates will also help students from the community to avail scholarships for higher studies from the state-funded board if their gross annual family income is less than Rs 8 lakh per year.

The board has also urged the state government to implement the 10 per cent quota for its community members under the economically weaker sections, as applicable for Central government jobs and admissions to central institutions.

Noting that every community has people who are forward and backward economically for various reasons, including historical, the official said the board would be empowered to serve the Brahmins.

“The board will provide interest-free loans to the financially weaker sections of the community,” said its Chairman H.S. Sachidananda Murthy.
