Ataullah Jokatte re-elected DK SDPI president; here’s the new committee

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.

Mangaluru, May 27: The Dakshina Kannada PU College Principals' Association on Wednesday appealed to the authorities to postpone the evaluation of PUC II answer scripts, as the Novel Coronavirus was still active and there was all possibility of the infection spreading.

Speaking to reporters here, Association President Umesh Karkera said, ''It is our duty to evaluate the answer scripts. But amid the fear of COVID-19 and lockdown, evaluators are not able to reach the valuation Centre to take up the work.

''The department of pre-university education has asked the Deputy Chief Examiners and the Assistant Examiners to reach the venue on May 27 and 29, respectively, to take up the evaluation work.

Bengaluru, Mar 4: CM BS Yediyurappa may reconsider plans to hike taxes and curtail populist schemes in his budget on Thursday as the Centre released part of GST compensation it owes the state. Officials said the Centre released the first instalment of the bimonthly compensation for October-November amounting to Rs 2,013 crore.

"This is welcome relief as the government has been scrambling to mobilise funds," said BT Manohar, member of GST consultative committee, government of Karnataka. The second instalment of Rs 1,523 crore is also expected to be released soon.

The CM, in his seventh budget, is expected keep the focus firmly on farmers and give top priority to irrigation, agriculture and welfare schemes.

The irrigation sector is expected to land the lion's share with an allocation of at least Rs 25,000 crore, followed by agriculture. Former CM Kumaraswamy had allocated over Rs 17,000 crore for water resources.

The bulk of funds is likely to go to the Upper Krishna (UKP) and Upper Bhadra projects, as it will help backward Kalyana Karnataka and central Karnataka regions. The two are also significant political blocs. The government will also seek assistance from the Centre for the UKP project in the erstwhile Hyderabad-Karnataka region, which enjoys special status under the Constitution owing to its backwardness.

Yediyurappa is also expected to spell out populist schemes for the poor.

Former CM HD Kumaraswamy had allocated Rs 17,212 crore in the previous budget for water resources and Yediyurappa is likely to go well beyond that figure. "Priority will be given to irrigation and farmers," Yediyurappa had said recently. "I am making efforts to present a budget within the financial constraints."

he amounts are released once every two months, but the Centre had fallen behind on payments. PX

"There are indications that another payment will be made."

The state's optimism stems from the fact that the Centre's GST collection crossed the Rs 1 lakh crore-mark for four successive months till February.

However, the CM could still hike tax rates marginally. At a pre-budget meet on resource mobilisation where Yediyurappa is learnt to have expressed willingness to borrow funds, officials from the finance department advocated raising tax rates instead.
