‘CM had even asked us to launch campaign’: Actors Shashi, Bhavana in shock after ticket denial

Apr 9: A panel of experts in the Karnataka state has suggested that the ongoing lockdown should be continued in districts identified as Covid-19 hotspots, including Bengaluru, to limit the spread of the pandemic.

IT companies and government offices providing essential services should be allowed to function with 50% staff, according to the committee headed by Narayana Health chairman Dr Devi Shetty, which submitted its report to chief minister BS Yediyurappa on Wednesday.

It has also asked the government to ease restrictions gradually and take adequate care over the next six months to contain the outbreak. The committee urged the government not to permit AC buses and metro services till April 30 and allow private vehicles only on alternate days (even-odd number-wise) for two weeks after April 15.

The government must close schools and colleges till May 31 and allow only inter-state movement of goods transport. The government could allow non-AC shops to open. It has suggested that the ban on inter-state train and flight services should continue.

Education minister S Suresh Kumar, who is the state Covid-19 spokesperson, said the Cabinet, which is meeting on Thursday, may discuss the recommendations and take a view on de-escalation of the lockdown.

Prime Minister Narendra Modi will interact with chief ministers through videoconference on April 11, after which the government will get an idea about the Centre’s thinking, he said.

While some states including Kerala, Maharashtra and Telangana have favoured continuation of the lockdown, Yediyurappa has not taken any stand publicly and has instead been implementing the Centre’s decision.

Six new cases

Karnataka on Wednesday reported six new Covid-19 positive cases, including that of a 65-year-old person in Kalaburagi, who died due to severe acute respiratory infection.

The health authorities have issued a notice to the private hospital -- where the deceased was initially admitted before being taken to a government hospital -- for not reporting the case to the government. The government has locked down the hospital, kept its entire medical team under quarantine, and police have registered a case of criminal negligence against the hospital authorities.

Of the other five positive cases, two had a travel history to Delhi, one had contact with a Dubai returnee and two others had close contacts with infected people.

This takes the total number of positive cases in the state to 181. Five people have died, while 28 have been discharged so far.

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, Jan 31: Karnataka Chief Minister B S Yediyurappa on Friday got the green signal from the BJP central leadership for the much-awaited cabinet expansion in the state and he is mostly likely to induct 11 ministers. Yediyurappa said the date of swearing-in will be decided in a day or two, although he indicated that it would most likely be held on February 3.

Currently, there are 18 ministers, including the chief minister, in the cabinet that has a sanctioned strength of 34. Sixteen berths are vacant. "Many of our suggestions have been accepted by Home Minister Amit Shah and BJP national president J P Nadda. If there are differences, we will discuss in Bengaluru and finalise it," Yediyurappa told reporters after meeting Shah in the Parliament Complex here.

Except for one or two, most of the disqualified JDS-Congress MLAs who got re-elected in the bypolls on BJP tickets will be made ministers, he said, adding there won't be any additional deputy chief ministers. However, sources said, a total of 11 ministers would be inducted into the cabinet.

"We discussed yesterday and now also. Shah has agreed to almost everything," Yediyurappa said, adding he is returning back "happy" after getting the nod for the cabinet expansion. "I am going happy," he said.

Yediyurappa had been anxiously waiting for the party high command's approval to expand his ministry amid intense lobbying by the aspirants. Opposition parties have been critical of the BJP and Yediyurappa over the delay in the cabinet expansion, alleging he was weak and that his administration had collapsed.
