Net neutrality: Facebook shuts Free Basics programme in India

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.

Suhaana shuddered with fear as she heard violent banging on her door on Sunday. The atmosphere was charged with communal tension after thousands of ruthless goons supporting contentious Citizens Amendment Act (CAA) launched a bloody onslaught against Muslims in the capital of India.

The family consists of Suhaana (name changed), her partially paralysed husband and two daughters. They are the only Muslim family in Madhuban mohalla of North Ghonda locality in north-east Delhi.

Hearts pounded louder than pounding of the door. Then the banging stopped and noises of men talking loudly came.

"I peeped out from a small window near the kitchen and saw our neighbours standing outside our entrance and arguing with 10-15 unknown people," Suhaana said.

It was the first day of the communal violence, worst in the decades, that fanned out to the entire north-east Delhi over the next three days and claimed at least 42 lives, left over 200 injured and properties worth crores destroyed. The death toll is feared to go up.

Later in the night Suhaana's family moved to one of their Hindu neighbour's house. There are about 30 Hindu households in the mohalla who kept vigil as the atmosphere deteriorated.

The next day, the violence escalated. The neighbours decided to shift Suhaana 's family to Gautampuri for their safety.

Suhaana recounted, "Our neighbours assured us that they are with us but as things were deteriorating, they said they wouldn't be able to protect us if a big mob of hundreds came. They advised us to move to the nearby Gautampuri locality and come back only after things become normal."

Rajkumar Bharadwaj brought the family to Gautampuri in the early hours on February 25.

Anil Gupta, 49, said, "It was tough to rescue them. We were asked by the rioters as to why we were saving the Muslims. But we had to, it is the people of my country who are suffering. It cannot be Hindus or Muslims."

Rajkumar Bharadwaj said, "Their youngest clung to me throughout. After I brought them here at Gautampuri, I felt good. Situation till then was not okay."

On Saturday, some semblance of normalcy returned to parts of north-east Delhi with some people opening their shops amid heavy police presence.

Meanwhile, the morbid sight outside GTB Hospital's mortuary, agonising groans in the hospital wards burnt down houses and shops remind Suhaana and others what they have been spared of.
