Dubai: BWF hosts lectures, picnic to mark UAE National Day

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 29: The high court has granted bail to a 37-year-old Bangladeshi woman from the Christian community on the strength of Citizenship (Amendment) Act 2019.

The court cited Section 2 of the amended Citizenship Act 1955, according to which minorities from Pakistan, Bangladesh and Afghanistan who entered India on or before December 31, 2014 should not be treated as illegal immigrants, while granting her bail.

Allowing the petition filed by Archana Purnima Pramanik, an illegal immigrant from Bangladesh, who claims to be staying in India since 2003, justice John Michael Cunha on Monday directed her to furnish a bail bond for Rs 2 lakh to the satisfaction of the investigating officer and cooperate with the probe.

The judge observed the allegations made against her must be proved in a full-dressed trial. Archana was booked for obtaining documents such as PAN and Aadhaar cards and also fraudulently obtaining an Indian passport on March 28 last year. Based on a complaint filed by the assistant passport officer, Archana was arrested on November 7, 2019 and her bail petition was dismissed by a sessions court on December 4, 2019.

Born on March 23, 1983 at Tanore, Rajshahi district of Bangladesh, Archana came to India in 2003 to pursue a career in nursing. After obtaining a diploma in general nursing and midwifery at Ranchi in 2006, she worked in many reputed hospitals.

In 2010, she got married to Rajashekaran Krishnamurthy and the marriage was registered at Ranchi. After the wedding, she moved to Bengaluru and obtained PAN, Aadhaar and voter ID cards.

On April 1, 2019, Archana applied for a visa to Bangladesh for herself and her son. During her journey on May 20, 2019, they were detained at Kolkata airport and released later. However, the regional passport office issued a notice revoking Archana’s passport and she was arrested by RT Nagar police on November 7, 2019.

Mumbai, June 9: A 45-year-old doctor posted in the 108 ambulance service at Malad railway station in Mumbai died of COVID-19 after two hospitals refused admission, in spite of the fact that he was a frontline warrior against coronavirus.

The victim is Dr Shaukat Ali, who was working with the 108 ambulance service for the last four years. A few days ago, he got his blood tests done after his health deteriorated. The result stated typhoid fever following which he started getting treatment at home in Malwani.

Ali's family ran from pillar to post to get him hospitalised in either a private or government hospital, to no avail.

"On Friday, his condition worsened and he started feeling breathless. Despite us calling the 108 ambulance service, no one picked up the call. So after waiting for a while, I and uncle's colleague, Dr Nigam, rushed him to SK Patil hospital in Malad East in an auto. But they refused us stating they were admitting only COVID-19 patients.”

“Then we took him to Desai Hospital, where doctors were initially ready to admit him but later refused stating lack of beds. They said we could take him home as his condition was fine," Zubair Shaikh, Ali's nephew said.

"But his condition worsened. So, I called Dr Nigam and we managed to admit him in Shatabdi hospital. On Sunday, when his results came out stating that he had COVID-19, doctors had already put him on a ventilator, where he passed away in the evening," he added.

Zubair further said, "Had the doctors at Desai Memorial Hospital admitted him, my uncle would have been alive today. It is a matter of great regret that a doctor, who was risking his life during this pandemic, could not get help from his own government hospitals."

Ali's wife and his two children's are in UP, while he was staying with his elder daughter who had recently appeared for HSC exams and preparing for NEET.
