Shiradi Ghat closed for 10 days after landslides topple heavy vehicles killing 2

Bengaluru, Jan 8: The all-India shutdown by trade unions and other organisations began with little impact in the tech city as normal life continued on a working day, an official said.

"No effect of shutdown in the city though banking operations are affected as bank staff are supporting the trade unions," a state official said here.

However, thousands of workers participated in other parts of Karnataka in the nation-wide shutdown call given by trade unions, protesting central government's anti-labour laws and privatisation policies.

Protesters were seen carrying the red trade union flags at several places such as Hassan, Chamarajanagar, Tumakuru, Mysuru, Bengaluru and others.

Massive protests were seen in Peenya, and Neelmangla areas of Bengaluru.

In Madikeri, stones were pelted at a bus and some protesters were detained in Kolar.

The trade unions are against the privatisation of railways and corporatisation of 49 defence production units.

Merging 44 labour laws into four code is also one of the demands of the protesting trade unions.

The protesters are demanding raising the minimum wage in the range of ₹21,000 - 24,000 per month.

The All India Trade Union Congress (AITUC), Centre of Indian Trade Unions (CITU), Indian National Trade Union Congress and Labour Progressive Federation (LPF) have given an all-India shutdown (Bharat Bandh) call on Wednesday.

Karnataka Chief Minister B.S. Yediyurappa instructed the intelligence chief and additional director general of police Kamal Pant to maintain law and order in view of the Bharat bandh when he apprised him of the situation.

Police tightened security across the city by deploying 11 deputy commissioners of police (DCPs), 23 assistant commissioners of police (ACP), 111 inspectors, 316 sub-inspectors, 476 assistant sub-inspectors, 4,547 constables along with 82 platoons of Karnataka State Reserve Police (KSRP).

In Bengaluru city, Metro services were not affected by the nationwide strike. In view of the shutdown, security was beefed at the Metro stations.

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.
