Govt tightens notes exchange norms, lowers limit to Rs 2,000

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.

Mangaluru: The police team investigating the case of bomb planting at the international airport here on January 20, took suspect Aditya Rao to several places in the city where he had frequented in the past few months, police said on Wednesday.

Police had earlier recovered a box from his bank locker at Udupi that contained a white powder which he claimed was cyanide. The substance has been sent to the Forensic Science laboratory for confirmation.

On further interrogation, Rao told police that he had a locker in a bank in Mangaluru also, where he was taken. Only some papers were seen in the locker, police said. He was also taken to the room where he stayed while he was working at a hotel in Balmatta here and to a hardware workshop from where he had purchased some spare parts, they said.

A 'live' explosive device was found in an unattended bag near a ticket counter of the departure gate of the airport here on January 20, triggering a scare before it was defused at a nearby open ground.

Police had released a picture of a man captured on CCTV camera as the suspect who placed the bomb and Rao later surrendered. Meanwhile, sources said the airport authorities got an anonymous call on Monday evening that a bomb had been planted in the airport. After thorough search, it was found to be a hoax. City police commissioner P S Harsha has warned of stringent action against those who make such calls.

Bengaluru, Mar 30: Karnataka Chief Minister BS Yediyurappa on Monday appealed to people to strictly follow the restrictions in the state, saying that the ending of 21-day nationwide lockdown imposed to contain COVID-19 depends on how the public adheres to the rules.

In a press statement, Yediyurappa appealed to the people to help the government to prevent the spread of coronavirus by strictly following the lockdown.

"People of Karnataka are known for tolerance and patience. They are law-abiding citizens. Now, the lockdown in wake of coronavirus is a testing time for them. It has come to test the patience of our people, especially the people of Karnataka. Prime Minister Narendra Modi himself has apologized and said that lockdown was an inevitable step taken by the government to protect people from the pandemic. We have to realise the predicament of a prime minister who always cares for the well being of the country and its people," the statement quoted Yediyurappa as saying.

"At this hour of crisis, it is not good on our part to come out of houses and violate the curfew. The ending of lockdown depends on strictness with which one follows the curfew and maintain social distancing. If one follows the curfew strictly, the lockdown period will automatically end on April 14. Whether to end the lockdown or not is in your hands," he said.

The Chief Minister urged not to test the patience of police, saying, "Already our police are under stress as they are working without any rest. Do not force them to use the force and later blame them for stern action."

He also appealed to follow the lockdown provisions and stay back in their home.
"The government has taken all measures to maintain the supply of essentials and food to the needy. Consider this situation as a blessing in disguise and spend your valuable time reading books which in turn will boost your knowledge and intellectual capacity. My earnest request to even the poor is spending your time by involving yourselves in creative activities inside your houses," Yediyurappa said.

"At the same time, it is time for us to respect the sacrificing work of the doctors, nurses, health staff and civic workers who are working round the clock to save the lives of hundreds of people affected by coronavirus. My appeal to you all strictly follows the curfew rules and maintains the social distance to combat COVID-19," he added.
