Police should understand that PFI and Bajrang Dal are not same: Sharan Pumpwell

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.

Kalaburagi, Mar 3: Former Karnataka Minister Priyank Kharge on Monday in a letter requested Karnataka Assembly Speaker Sri Vishveshvaraya Hegade Kageri that the restricted media coverage in Assembly Budget session was not the right thing and it will be danger of for healthy democracy.

The letter written by Mr. Kharge to the Karnataka Assembly speaker which available to the press said that the fourth pillar of democracy 'Media' ban from covering assembly proceedings was not a healthy move and requested to immediately withdraw the government order in this regards, he said.

Bengaluru, Mar 27: Oncologist Dr. Vishal Rao, HCG Hospital Bengaluru on Friday said that human body cells release interferon chemical to kill viruses but it cannot be released by cells in the case of COVID-19 cases, leading to weak immune system. However, a therapy of specific concoction could be useful in treating COVID-19 patients.

"We got hold of some preprint suggesting that interferon is effective in COVID19," said Rao.

Speaking to news agency, he continued saying "When we withdraw blood for regular check-ups, we get buffy coat which can be used to take out cells and form interferon. These two chemicals and some other cytokines, in a specific concoction, could be potentially very useful in treating COVID-19 patients."

Rao said that they have built a concoction of cytokines which can be injected to reactivate immune system in COVID-19 patients.

"We are in a very initial stage and hope to be ready with its first set by this weekend. We have applied to the governement for an expedited review. We have also presented this before the state government" said Rao.

"We have a team of infection specialist, ICU team and other...all of us have worked together to build something that we believe. We want to serve the society at this hour of need," he added.

Dr Rao clarified that this is not a vaccine and this particular interferon therapy does not help to prevent the infection of COVID-19. However, this is focused and targeted towards COVID-19 positive patients or those who have just incubated the virus.

"We believe that in early stages as well as the patients who have just incubated, this particular therapy of interferon gama and other concoction of cytokines could be an effective method. In the late stages we are looking at specific dosage of the cells which are our own body cells which can actually be affective and could also be of use for the ventilator patients," he added.

Meanwhile, Dr Gururaj, Immunologist and Scientist told ANI that they are trying to cover two aspects, one is the early stage patients where they are trying to improve their immune systems.

"As Dr Vishal said, we are trying to see whether we can use the cytokines from our own immune cells which is a natural process but it is hampered in infected patients," said Dr Gururaj.

"In the last phase we are using cells which are used from the bone marrow of the patient or donors. We can use those cells to reduce the inflation and so called cytokines release syndrome which is basically the inflammatory response of the body," he added.
