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, Apr 8: A 65-year-old man from Kalaburagi district became the fifth COVID-19 fatality in Karnataka, where six new positive cases were confirmed, pushing the tally in the state to 181, the health department said on Wednesday.

The man with Severe Acute Respiratory Infection (SARI), died at a designated hospital in Kalaburagi on Tuesday, a day after being shifted from a private hospital where he was initially treated for two days.

"On April 4, he had got admitted to a private hospital, on April 6 he was shifted to ESI hospital, where he passed away," Primary and Secondary Education Minister Suresh Kumar told reporters here.

The private hospital had been locked and its entire medical team quarantined, he said, adding a notice had been served on it for act of "criminal negligence" (by not referring the patient to designated hospital) and will be followed with a police case.

"He was suffering from SARI, on collecting his sample, tests have revealed that he was positive....investigation is on to find how he got infected," the Minister said.

Noting that the hospital in this case did not refer the patient to the designated hospital and kept treating him for two days, he appealed to all private healthcare facilities to inform authorities if anyone showed any indications for COVID-19.

"As of 5 PM on April 8, cumulatively 181 COVID-19 positive cases have been confirmed in the state, it includes 5 deaths and 28 discharges," the health department said in a bulletin.

Out of the positive cases, 71 are those who had come back from foreign countries, while remaining 110 are contacts and those who had gone to Delhi, the Minister said.

Kumar also said an expert committee comprising Narayana Health founder-chairman Dr Devi Prasad Shetty and Jayadeva Institute of Cardiovascular Sciences director Dr C N Manjunath among others, constitutedto devise an exit strategy for the lockdown, has submitted its reports with various recommendations to Chief Minister B S Yediyurappa.

The chief minister and officials were examining it which was likely to come up before the cabinet meeting on Thursday after which the details will be shared, he added.

The health department said the six fresh cases reported on Wednesday included the elderly man from Kalaburagi who died.

Among the positive cases are a woman from Uttara Kannada with history of SARI and contact of a Dubai returnee, a 72- year-old woman from Kalaburagi, who is mother of a patient that tested positive for the disease; a man from Mandya with contact to two patients.

Others include a man from Chikkaballapura with travel history to Delhi and a woman from Bengaluru also with a travel history to the national capital.

Contact tracing is in progress for all the cases, the bulletin added.

A 53-year-old Indian worker in the UAE has missed a special repatriation flight after he dozed off at the Dubai International Airport, a media report said.

P Shajahan, who worked as a storekeeper in Abu Dhabi, was supposed to fly to Thiruvananthapuram on the Emirates jumbo jet chartered by the Kerala Muslim Cultural Centre (KMCC) Dubai, Gulf News reported.

It was the first-ever jumbo jet chartered for repatriation.

Shajahan, who had paid 1,100 dirham (USD 300) for the ticket, said that he did not sleep on the previous night as he kept on waiting for the confirmation of his ticket for the jumbo jet flying 427 stranded Indians to Kerala, it said.

He reached the airport early in the morning and after finishing the check-in procedures and rapid test, he reached the waiting area of the boarding gate at Terminal 3 around 2 PM local time, the report said.

“I sat away from most of the others. But I fell asleep after 4.30 PM,” he said.

S Nizamudeen Kollam, who coordinated the charter flight, said that the airline officials could not trace Shajahan when the flight was to take off.

“He woke up and called us after the flight left. It is sad that he missed the flight, which was the first-ever jumbo jet chartered for repatriation. We are now trying to send him on another Emirates flight that we are chartering on Saturday,” Kollam said.

Since Shajahan did not have any money, Jasimkhan Kallambalam, organising secretary of KMCC Thiruvananthapuram, went to the airport to meet him on Friday.

“Since his visa was cancelled, he could not come out of the airport. He had only eaten the snacks in the kit KMCC had given. We managed to give him some cash for buying food through KMCC volunteer Alamsha Latheef,” Kallambalam said.

In March, another Indian expat had fallen asleep in the same terminal and missed the last flight home before flights were suspended due to the COVID-19 pandemic.

He was stranded here for over 50 days before getting repatriated.
