SC/ST Federation to move Supreme Court against HC's ruling over 'Mogera' caste

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.

Ballari, June 30: A video clip of dead bodies of covid-19 victims being disgracefully thrown into a pit said to be in Karnataka’s Ballari has gone viral on social media triggering outrage from netizens.

Ballari Deputy Commissioner SS Nakul ordered a probe. He told media persons that the veracity of the video is still under question and that it still needs to be established if the video was taken in Ballari.

In the video, a pit is seen which appears to be disinfected. The video features masked men covered in body suits bringing dead bodies from a black hearse van in black body bags one by one and throwing the dead bodies into the same pit. In all, three dead bodies are thrown into the same pit in the video.

"We have assigned an Additional Deputy Commissioner (ADC) to enquire and verify the same. We are awaiting reports. We don't know yet if it (the video) is from Ballari or not," Nakul said.

The district which has so far reported around 800 cases in the last three months has also witnessed around two dozen deaths.

Twitterati on Tuesday raised questions about the handling of the bodies. "Even dead have some respect and they deserved a decent burial," said a social activist from Ballari. Similar reactions echoed on social media and some also pointed out on how the family members who have to stay away from burials feel about it.

Covid burial protocol

According to the protocol set by the Union Health Ministry for the burial of Covid-19 patients, the patients' orifices (nose, mouth and ears) have to be sealed and the body has to be wrapped in three layers of personal protective equipment (PPE). Thereafter it should be placed in a body bag. Family members should not be allowed to accompany the body in the hearse van. Covid-19 victims have to be given a deep burial. The grave should be minimum 10-feet deep.

The grave should be disinfected with bleaching powder and the area should be cordoned off so that the general public is not in the vicinity.  The vehicle used to transport the dead body of a Covid-19 victim -- ambulance or a hearse van -- has to be disinfected for 16 hours before being used again. Most Covid-19 victims in the state have had burials in the absence of family members as they are generally in quarantine for being the primary contacts of the patient.
