Hot weather theory falls flat, coronavirus more potent in India post-summer

Agencies

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.

New Delhi, Apr 16: Minority Affairs Minister Mukhtar Abbas Naqvi on Thursday directed state waqf boards to ensure strict implementation of lockdown and social distancing guidelines during the holy month of Ramzan starting next week amid the coronavirus pandemic.

At a meeting via video conferencing, Naqvi asked the state waqf boards' officials to create awareness among people to offer prayers and perform other religious rituals like "iftar (breaking of fast)" during Ramzan, which begins on April 24 or 25, staying inside their homes.

More than seven lakh registered mosques, eidgahs, imambadas, dargahs and other religious and social institutions come under state waqf boards across the country. The Central Waqf Council is the regulatory body of state waqf boards in India.

"We should cooperate with health workers, security forces, administrative officers, sanitation workers. They are working for our safety and well-being even putting their own lives at risk in this coronavirus pandemic," Naqvi said.

"We should also demolish rumours and misinformation being spread about quarantine and isolation centres by creating awareness among people that such centres are only meant to protect people, their families and the society from the pandemic," the minister said.

Naqvi told all the state waqf boards and religious and social organisations that everyone should remain cautious of any type of fake news and conspiracies aimed at creating misinformation. 

"Authorities have been working for safety and well-being of all citizens of the country without any discrimination. Such type of rumours and conspiracies are a nefarious design to weaken the fight against coronavirus," he said.

"We should work united to win this fight against corona by defeating any type of rumour, misinformation and conspiracy," the minister said.

Naqvi asked officials of all the state waqf boards to play an active and effective role in ensuring that people follow the guidelines of the Union Home Ministry, state governments and the Central Waqf Council while fulfilling religious responsibilities during Ramzan.

In view of the challenges of the COVID-19 pandemic, all religious and social activities and mass gatherings in all the temples, gurdwaras, churches and other religious and social places of the country have been stopped, he said. 

Similarly, any mass gatherings in mosques and other Muslim religious places of the country has also been stopped, Naqvi said.

He said that due to the COVID-19 threat, religious leaders as well as religious and social organisations from all regions of the country, have appealed to people to offer prayers and perform all other religious rituals staying inside their homes during Ramzan. 

Most of the Muslim nations of the world have also banned mass gatherings at mosques and other religious places during the holy month, he pointed out.

Prime Minister Narendra Modi, in cooperation with all the state governments, has been working effectively for the safety and well-being of the people, he said.

The cooperation of the people has brought great relief to India in the war against COVID-19 Naqvi said, adding that several challenges are still there before the country. 

"We can defeat these challenges of the coronavirus pandemic by following all the guidelines of the central and state governments strictly," he asserted.

Chairman and senior officials from state waqf boards such as Uttar Pradesh (Shia & Sunni), Andhra Pradesh, Bihar (Shia & Sunni), Dadra & Nagar Haveli, Haryana, Karnataka, Kerala, Madhya Pradesh, Punjab, West Bengal, Andaman & Nicobar, Assam, Manipur, among others participated in the meeting.

State waqf boards from Rajasthan, Telangana, Delhi, Chhattisgarh, Gujarat, Himachal Pradesh, Jammu and Kashmir, Jharkhand, Maharashtra, Odisha, Puducherry, Tamil Nadu, Tripura and Uttarakhand also participated.
