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.

Mysuru, May 1: Four people who brought a dead man’s body from Mumbai for cremation in his native place in Mandya district in Karnataka have tested positive for Covid-19 virus, and now the administration is trying to find out if the man himself had been an undetected positive.

According to Mandya district deputy commissioner M V Venkatesh, the deceased man was a 53-year-old native of B Kodagalli of Pandavapura taluk, Melkote hobli in Mandya district. He died after suffering a heart attack at the U N Desai government hospital in Mumbai on April 23.

The cremation took place outside the man's native village after the local administration refused to allow it inside the village.

Wanting the final rites performed in his native place, the man’s family got the body embalmed and procured all the medical records and certificates from the hospital and brought it in an ambulance belonging to the Desai government hospital.

When they reached Pandavapura taluk in Karnataka on the evening of April 24, the local administration did not allow the body to enter the village but allowed the relatives to cremate it outside the village.

And since the family had come from Mumbai, the district administration quarantined all seven of the man’s relatives, and their samples were sent for testing on 28 April.

The results showed that the deceased man’s 25-year-old son, daughter-in-law, daughter, and two-year-old grandchild are positive for Covid 19. All of them have been admitted at the Mandya Institute of Medical Sciences although they have no symptoms.

Deputy commissioner Venkatesh said that in the Desai hospital records in Mumbai there was no mention whether or not the man had been tested for Covid-19. “We are writing to Desai hospital to clarify if the deceased person was tested for Covid 19. It is also possible that the family got infected by the man’s son who works in the loan department of ICICI Bank in Mumbai and visits several offices in different areas of Mumbai,” he said.

The man’s ancestral B Kodagalli village now has been sealed off. Though tests done on other members of the family have come back negative, the Mandya administartions plans to repeat their tests.

So far 26 people have tested positive for Covid 19 in Mandya district.

Bengaluru, Mar 25 : Karnataka recorded its highest single-day tally to date, as 10 people tested positive, taking the total number of cases to 51 in the state.

The rise in cases adding to the growing national tally of people who have tested positive for COVID-19.

The daughter of a former union minister from the Bharatiya Janata Party (BJP) from Karnataka has also tested positive.

Bengaluru accounts for 32 of the total 51 cases recorded in the state so far,including three who have fully recovered and released.

Dakshina Kannada has five confirmed cases, Chikkaballapura and Kalaburagi has three cases each, Mysuru has and Uttara Kannada has two cases each and four other districts have one case each.

Prime Minister Narendra Modi has announced a 21-day lockdown of the country to keep people indoors and contain the spread of the virus in the community.

The government has also been trying to scale up testing.

Medical education minister K.Sudhakar on Wednesday told Mint that Karnataka will scale up testing by 10-fold with the help of government and private labs approved by the Indian Council of Medical Research (ICMR).

A total of 2,438 people have been tested in Karnataka and 2242 have tested negative, according to state health department. 214 people are lodged in medical hospitals.
