Fake In India': Techie praised by Modi arrested for printing fake Rs 2K notes

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, May 28: In a first of its kind initiative, the Karnataka government will soon launch 'Statewide Health Register', a project to maintain the health database of all its citizens, announced Medical Education Minister Dr K Sudhakar on Wednesday.

The project will kick start from Chikkaballapura and Dakshina Kannada districts.

"With a vision to efficiently deliver quality healthcare to every citizen, Karnataka will soon have a Statewide Health Register. The pilot project will be implemented in Chikkaballapura & Dakshina Kannada dist shortly and completed in 3-4 months. @CMofKarnataka @PMOIndia @JPNadda," tweeted the Minister.

The government plans to get the data collected with the help of a team of Primary Health Centre (PHC) officials, revenue officials, Education Department staff and ASHA (Accredited Social Health Activist) workers.

"They will visit each household and collect health data of all the members of the family. This will not just help the government to provide better health care facilities, but also build an efficient resource allocation, management and better implementation of various citizen-centric schemes in the state," the minister added.

Sudhakar also said that the COVID-19 pandemic has demonstrated the necessity of having a robust, real-time public health system.

"Very few countries in the world have taken such an initiative. It is a futuristic project which will include 50 per cent partnership of private hospitals. It would be a cumbersome process but if we do this and digitise it, the data could be used for multiple purposes. The data would help us prioritise healthcare based on geography, demography, and other targeted measures. It would also help medical professionals and scientists for innumerable studies," he said.

"We have consulted all specialists from 18 different departments, and taken their advice into account," said the minister.

Madikeri, Apr 22: The quality of water in the River Cauvery in Kodagu district has improved significantly following the nationwide Lockdown.

The discharge of effluents from home stays and resorts situated on the banks of the river in the district has stopped due to lack of visitors. The discharge of waste water had made the river impure all these years.

The suspension of boat ride in Dubare has reduced the pollution from diesel motorboats in the river. For the last few years, the water quality of the river had reached 'C' category from 'B' category during the summer.
