Mangaluru, July 17: For the first time, Dakshina Kannada saw over 3,00 new coronavirus cases in a single day. The coastal district today recorded 311 positive cases. 

The number of active cases in the district is 1,725 while its overall tally stands at 3,074.

Out of the 26,242 samples tested so far, 23,168 were tested negative. 

As many as 1,278 people were discharged after fully recovering so far including 115 people who were discharged today.

The district also recorded deaths of 8 covid-19 patients in past 24 hours including a woman. The deceased are aged between 53 years and 78 years. 

With this the total number of deaths in the district mounted to 71 including 12 patients from other districts who were admitted in hospitals here. 

Meanwhile, Karnataka reported 3,693 fresh cases in the last 24 hours, which raised the virus case count to 55,115. The number of recoveries reached 20,757, including 1,028 on Friday.

At 115 fatalities, the state witnessed its biggest single-day jump. Bengaluru accounted for 75 of these 115 deaths. The number of active cases in the state are 33,205, including 508 patients who are in ICU. The state's death toll reached 1,147 while that of Bengaluru stands at 582.

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.

Shivamogga, Feb 24: Karnataka Chief Minister B S Yediyurappa on Monday said that he has been invited at the banquet hosted for US President Donald Trump at Rashtrapathi Bhavan on Tuesday, but, he is yet to decide on his presence.

“I have been invited, but I have various engagements and work, let’s see. I have not yet decided on what to do. It is true that I got the invitation,” he told reporters here.

"President of a powerful and rich country like United States of America visiting India is not a normal thing. He (Trump) has said that he personally shares good relationship with Prime Minister Modi and has confidence in him…let’s wait and see", Mr Yediyurappa said in reply to a question.
