Kasaragod, Mar 31: Two more Kasaragod natives lost their lives on Monday due to blockade of the interstate border by Karnataka police in the wake of outbreak of novel coronavirus.

They could not get emergency health care as the Karnataka police stopped the ambulance carrying them to a hospital in Mangaluru at the border.

Another critically-ill person, who was sent back by Manguluru hospital authorities on March 23 for being a Kasaragod native, also died on Monday.

This is the fifth such case in many days.

The deceased are Madhavan, 50, Ayesha, 55 and Aziz Haji, 61 respectively.

All three of them lived near the Karnataka border.

Madhavan, who hailed from Thummanattu in Manjeswaram, died enroute to Kanhangad hospital after being denied entry to cross over to Karnataka. He had an acute bronchial attack.

Udyavar native Ayesha, an asthma patient, was referred to the Mangaluru Hospital by the hospital authorities at Uppali. When the authorities stopped her at the border, she was taken to the Kanhangad hospital. However, she died before reaching the hospital.

Aziz Haji, from Nayabazar Cherugoli MA Cottage at Uppala, was allegedly refused entry into a Manguluru Hospital on March 23 on account of being a Kasaragod native. Haji was a dialysis patient at the hospital. “We were unable to contact his doctor at the time,” his relatives said. Haji, who was on the ventilator, lost his life Monday morning.

The district authorities has appealed to the Government to intervene in the matter and influence Karnataka as to lift a ban in crossing over for ambulances carrying critical patients.

The Kasaragod MP, Rajmohan Unnithan has said he would move the Supreme court against this.

Kerala Chief Minister Pinarayi Vijayan has already taken up the issue with the Centre.

Kerala HC takes up issue with Karnataka AAG

The Kerala High Court on Monday sought the views of the Advocate General of Karnataka on the issue of the government of the neighbouring state blocking its borders with Kerala.

Considering a Public Interest Litigation (PIL) filed by Kerala High Court Advocates Association, seeking a direction for opening the roads, a bench comprising Justices A K Jayasankaran Nambiar and Shaji P Chali requested the Advocate General of Karnataka to join the hearing at 11 am on Tuesday through video conferencing.

The Court orally observed that the blockades erecting embankments on the inter-state roads would affect the people's right to life.

The Karnataka government blocked the state highway with to prevent movement of vehicles carrying essential goods and people seeking emergency treatment at hospitals in the city of Mangalore bordering Kasaragod.

With 97 infected patients, Kasaragod has the largest number of COVID-19 cases in Kerala. 7,437 people are under observation in the district.

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.
