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, Mar 19: The Karnataka government has extended the statewide coronavirus shutdown till March 31 as the number of positive cases rose to 14, of whom 11 are those who came in from foreign countries.

In an emergency Cabinet meeting, the state government set up a task force of four ministers to lead the defence against the virus. This core team will have Rs 200 crore to orchestrate the combat.

When chief minister B S Yediyurappa announced the shutdown last week, it was to be in force until March 21, but it was always unlikely that the Covid-19 scare would have waned by then.

Several more restrictions were announced today. Quarantine will be mandatory for all passengers arriving from foreign countries. While schools, colleges and business establishments will continue to be closed, restrictions have been extended to marriages, fairs and social functions as well.

Public entry to Vidhana Soudha, Vikas Soudha and the M.S. Building has been barred till March 31.

While setting up the task force, the government has earmarked Rs 200 crore for the coronavirus campaign. The chief minister said there is no dearth of funds for fighting the virus.

The task force will have deputy chief minister Ashwathnarayana, home minister Basavaraj Bommai, medical education minister Sudhakar, health and family welfare minister B Sreeramulu and chief secretary T M Vijaybhaskar.  Sreeramulu will head the task force.

The task force will monitor coronavirus cases on a daily basis and orchestrate the response of all stakeholders. It will issue a daily bulletin on the epidemic and also run awareness campaigns.

With quarantine now mandatory for passengers coming in foreign countries, community centres, hotels, convention centres, resorts and even PGs will be rented to accommodate the new arrivals.

The compulsory quarantine will be for 15 days.

A quarantine stamp will be imprinted on the right hand of passengers coming in from foreign countries.

Since the Centre has relaxed the rules for using SDRF funds, the state government will draw from it to contain the pandemic; therefore, there will be more funds available to all districts, chief minister B S Yediyurappa said in the Assembly.

In further measures, all passengers and suspected Covid-19 cases will be tracked by their mobile phones.

Primary stage

“We are in the first and second stages of the epidemic. The virus is still at a primary stage and has not spread to community level," medical education minister Sudhakar said in the Assembly.

"It is important that we do not let the epidemic enter the third stage. It is possible if we implement stringent measures. People have responded positively to the state government’s measures and are cooperating with our decisions," Sudhakar said.

Bengaluru, May 22: Police commissioner Bhaskar Rao on Friday said the next two Sundays will be ‘full curfew days’ and the city will be under complete lockdown between 7pm Saturday and 7am Monday.

Addressing the media, the top cop said all essential services will be excluded from the curfew. “People attending weddings and other ceremonies can travel. Those wanting to buy food products or medicines too can step out. However, like in lockdown 1.0, people found loitering unnecessarily will be punished,” he said.

According to Rao, city roads will be barricaded like how it was done during lockdown 1.0 and 2.0.

A senior police officer told TOI that during this period, vehicles could be seized under the Disaster Management Act-2005. “So, we request the public not to come out unnecessarily. If we find people roaming in vehicles, we shall seize the rides and owners will have to approach the court later to get them released,” he said.

The government has extended the lockdown till May 31, which includes two Sundays.
Earlier in the day, the state government allowed inter-state travel from Karnataka with the consent of the receiving state. Praveen Sood, Karnataka DG and IGP, said, “Inter-state pass is not required to go out of Karnataka as long as you have the consent of the receiving state. Due to the lockdown, migrant workers, pilgrims, tourists, students and other persons are stranded at different places. They would be allowed to move as usual.”
