Karwar, Jun 3: The India Meteorological Department (IMD) has issued an alert, predicting thundershowers and heavy rainfall over north interior Karnataka, coastal Dakshina Kannada and Udupi over the next three days.

With Cyclone Nisarga hitting the Uttara Kannada coast on Tuesday,  parts of coastal Karnataka received heavy rainfall. Gusty winds tore through the coastal towns, as the sea too turned violent with rough waves smashing the shore.

The alert was issued with the advancement of Nisarga from east-central Arabian Sea to north Maharashtra, and adjoining south Gujarat coast. “Though it does not cover Karnataka, the range of cyclonic winds is very big and reaches north interior Karnataka also.

So an alert has been called out,” CS Patil, director in-charge, IMD, Bengaluru, said. The weather department has forecast a severe cyclonic storm and then a depression. Patil said formation of systems is a common factor before the onset of the monsoon and they help in its advancement.

“Cyclone Nisarga is helping in the quick advancement of the southwest monsoon to Karnataka, and the monsoon is likely to arrive before the scheduled date as conditions are favourable,” he added.

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, Apr 20: As many as 59 people were arrested on Monday for attacking police and health officials at the minority dominated Padarayanapura in the city when they went to quarantine some people, police said.

"Fifty-nine people have been arrested (in Padarayanapura) and have been taken into custody. The people attacked the officials who had gone to quarantine some poeple who were the primary and secondary contacts of three COVID-19 patients," a police officer said.

A large number of people, mostly youth from the minority community poured on to the road on Sunday and thrashed the health workers who had gone to quarantine some people who were the primary and secondary contacts of the health workers.

The officials were allegedly beaten black and blue.

Some local residents who went to the rescue of these officials were also thrashed.

According to police, one among the arrested is a woman by name Firoza who had allegedly instigated the mob to attack the health and police officials.

Subsequently, a large number of police personnel were deployed in the area to avert any untoward incident and to quarantine those who are suspected to be infected with COVID- 19.

Blowing sirens, a strong contingent of policemen carried out a flag march in the area.

The Bengaluru police commissioner Bhaskar Rao later called on Chief Minister B S Yediyurappa and briefed him about the situation in Padayarayanapura.

The violent incident drew angry reactions from various quarters.

Karnataka Home Minister Basavaraj Bommai said an incident like the one at Padayarayanapura will not be tolerated.

"I met Chief Minister and briefed him about the incident. He has told us to act strictly. I have told the same to my officials. We won't tolerate such acts by anyone. We have arrested 59 people. Five FIRs have been registered," the minister told reporters.

Bommai, who visited the area took the senior police officials to task for not being present on the spot when the incident took place.

"Where were you? What were you doing when the incident happened?" he questioned a senior police officer.

"We will demonstrate to the people what is containment zone, what is seal down and what is police action," he said.

Condemning the incident, Health Minister B Srimulu warned those who indulged in such activities.

"The inhuman act of attacking police and health workers in Padarayanapura is highly deplorable. Our government will take appropriate step against those indulging in the attack on health officials and police officials who had gone there to protect them," he tweeted.

BJP's firebrand MP Shobha Karandlaje reacted sharply.

"Seculars attack #CoronaWarriors when they were quarantining the secondary contacts of #Covid19 in Padarayanapura of BLR. While #HealthcareHeroes are working overnight to contain #CoronaPandemic, these morons are assaulting our heroes! Let's not be soft on these anti- nationals!" Karandlaje tweeted.

Meanwhile, the minority leaders called on Congress state president D K Shivakumar to persuade the people of the minority community to assist in identifying the COVID-19 patients or carriers.

Former chief minister H D Kumaraswamy too condemned the attack and demanded stringent action against the culprits.

The Congress MLA from the area B Z Zameer Ahmed Khan while condemning the incident, sought to know why the health workers and police officials went to the area late in the night and not in the morning.

"Why did the police and the health workers go in the night when I had told the BBMP Commissioner that I will take them at 10 am?" Khan told reporters.

Defending those who attacked the government officials, Khan said they were uneducated labourers who didn't know what they were doing.

Padarayanapura and Bapuji Nagar were among the first areas to be completely sealed as people were not abiding by the prohibitory orders under Section 144 of the CrPC.
