Muslim groups in Mangaluru unitedly protest against vilification of Zakir Naik

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 30: The Karnataka government on Thursday decided to allow migrant workers, tourists, students and others stranded in different parts of the state due to the ongoing lockdown to return to their native places, a day after the Centre issued guidelines for the process.

This will be a one-time movement and the government would arrange buses for those in need but they should bear the expenses, Law and Parliamentary Affairs Minister J C Madhuswamy said. He also said people willing to return to the state would have to undergo tests for COVID-19. The decision was taken at the state cabinet meet and it might come into effect from Friday as the Chief Secretary will have to issue an official order, he said.

"Prime Minister Narendra Modi had taken decision on movement of people and the Centre had issued a circular in this regard. Following this we have decided to permit interstate and inter-district movement," he told reporters here.

Travel expenses should be borne by those willing to return and if they want the government can provide buses from the state transport corporations. The Union Ministry of Home Affairs on Wednesday issued orders allowing migrant workers, tourists, students and other people stranded in different parts of the country to move to their respective destinations with certain conditions, giving a big relief to the distressed people. Decision on opening of salons and liquor shops will be taken after May 3, he said.

Madhuswamy said permission would be given for one-time movement of labourers and others who want to go from one district to other for work or any other purpose. Those operating industry or establishment and want to move from place to place for management purpose will be given passes with strict scrutiny and through checks.

Responding to a question, the minister said, "we don't know yet how many are willing to go, where they will go, if some one asks for permission, we will permit." "One family or two or three people want to go, they can use taxi. If too many people want to go, we will provide facility through transport corporation buses," he said.

Bengaluru, Apr 18: With 12 fresh cases of the COVID-19 infection, including one woman, the total number of novel coronavirus cases in Karnataka surged to 371 on Saturday.
