Udupi, Jun 2: As many as 150 persons tested positive for COVID-19 in Udupi district on Tuesday. This is the highest spike in COVID-19 cases in a single day in the district.

According to the district administration, all the 150 persons have travel history from Maharashtra. The number of COVID-19 cases has more than doubled when compared to June 1, when the district recorded 73 cases.

Deputy Commissioner G. Jagadeesha said here that of the 150 persons who tested positive, 120 were male and 30 female. This also included nine children aged less than 10. All these persons had been shifted to the designated hospitals for treatment.

He said that since 2,000 persons were tested in the last two days, 150 persons were found positive. Earlier, about 200 to 300 persons were being tested daily and about 10 to 15 used to be found positive. Nearly 10 % of persons coming from Mumbai/Maharashtra tested positive for COVID-19.

“We have 1,120 beds to treat COVID-19 positive cases in the district. Even after including these 150 persons, we still have 800 beds left. Hence, people need not panic. We will provide treatment for all affected persons,” Mr. Jagadeesha said.

With 150 cases on Tuesday, the total number of persons who have tested positive in the district since March has touched 410. There are 345 active cases.

As many as 63 persons who had recovered had been discharged from hospitals. There was one death due to the disease on May 14. The test reports of nearly 5,400 persons are still awaited.

The district had recorded only three COVID-19 cases from March 29 to May 14. But the number of COVID-19 cases started increasing from May 15.

Udupi, May 2: During the lockdown period the Department of Public Library digitised more books to the Karnataka Digital Public Library (KDPL).

According to the data released by the KDPL issued here on Saturday , as on April 29, 89,239 people from the State have already registered for the digital library.  From these 1,807 are from Dakshina Kannada district and 605 from the Udupi district.

The digital library already has a repository of 35,500 e-books, 4,800 videos, 59,980 e-journals and 1,112 items for children.

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.
