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, Apr 12: A 10-month-old baby who tested COVID-19 positive on March 27 completed treatment and discharged from hospital on Saturday.

He was the youngest positive case in Karnataka, from Sajipanadu village in Bantwal taluk.

The child had been with his mother to a relative's house at Monetepadau village, situated on the Karnataka-Kerala border in the first week of March.

A few days later the child developed an acute respiratory illness and tested positive for the COVID-19 virus.

Treating the breastfeeding child was challenging for doctors as he had to be isolated. A team of doctors from Wenlock Hospital took up this challenge and successfully cured the baby.

Test reports on his mother and grandmother too have returned negative. They too had been under quarantine and were discharged with the baby.

Another positive development was that no COVID-19 case has been reported from the child's village.  

The entire Sajipanadu village was completely sealed after the child tested positive and the district had provided all the necessary supplies to the villagers.

Bengaluru, Jul 19: The Karnataka Deputy Chief Minister C N Ashwathnarayan on Saturday inspected the country's first modular Intensive Care Unit (ICU) containers.

A notice from the Chief Minister's Office (CMO) said that the new mobile modular container ICUs, which will be used in the fight against the ongoing COVID-19 pandemic, have been created by Rinac India Limited, known for setting up sanitised operation theatres and clean rooms in hospitals.

On a pilot basis, the Deputy CM, who is also in charge of setting up COVID-care centres, said that 10 modular container ICUs will be deployed at the KC General Hospital in Malleshwaram. Each of the containers will have five beds.

Deputy CM Ashwathnarayan also said, "These mobile ICUs donated by Rinac will be useful, particularly in times of a crisis like COVID 19 or any natural calamity."

"The entry of health officials will be through an airlock, and entry of patients will be through a different door. There will be two doors for patients and can be increased if need. ICUs are fitted with cameras to monitor online from a centralized monitoring station, thereby limiting the exposure of the health personnel," the CMO informed.

The CMO further added, "the advantages of this new system are that the prefabricated modules of 5 can be shifted to any location by trailers and it is easy to deploy multiple containers to create a common facility. They are easy to clean and the airtight functionality ensures that no moisture or heat ingression happens, hence, it is easy to air-condition or ventilate."
