Hidden camera at women's toilet: M.Sc. student Santosh M arrested

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, Jul 10: The Karnataka cabinet gave its approval for "The Karnataka Contingency Fund (Amendment) Bill, 2020" to enhance the contingency fund limit to Rs 500 crore in the wake of the COVID-19 pandemic.

This will be an ordinance making one time enhancement in the limit as the government needs money to make payments immediately, Law and Parliamentary Affairs Minister JC Madhuswamy told reporters after a cabinet meeting.

Under the contingency fund, the government had room to spend up to Rs 80 crore without budget provision.

"...but this time due to COVID-19 as we had to give money to some sections that were in distress like barbers, flower and vegetable growers, taxi drivers, among others, we have decided to increase the limit to Rs 500 crore," Mr Madhuswamy said.

"As assembly was not in session and as we had to make payments to those in distress immediately, this decision has been taken," he added.

The cabinet today ratified the administrative approval given to carry out civil and electrical works to install medical gas pipeline with high flow oxygen system at district hospitals, taluk and community health centres coming under Health and Family welfare department in view of COVID-19.

The minister said about Rs 207 crore is being approved for this purpose.

It also ratified procurement of medical equipment and furniture for public healthcare institutions of the health and family welfare department worth Rs 81.99 crore.

According to the minister, the cabinet has decided to bring in an amendment to section 9 of the Lokayukta act, which mandates that the preliminary inquiry contemplated by Lokayukta or Upalokayuta should be completed in 90 days and charge sheeting should be completed within six months.

Noting that at the Agricultural Produce Market Committee (APMC) cess was being collected, he said as the government had brought in an amendment to the APMC act, there was demand to reduce the market cess. "So we have reduced it from 1.5 per cent to one per cent."

Approval has also been given by the cabinet to bring Karnataka Vidyuth Kharkane (KAVIKA) and Mysore Electrical Industries (MEI), which are presently under the control of Commerce and Industries department, under administrative control of the energy department.

Other decisions taken by the cabibinet include deployment and implementation of "e-procurement 2.0" project on PPP at a cost of Rs 184.37 crore and ratification of the action taken to issue orders on March 24 to release interest free loan of Rs 2,500 crore to ESCOMs for payment of outstanding power purchase dues to generating companies.

The cabinet also gave administrative approval for setting up of an Indian Institute of Information technology at Raichur.

"Under this, we are committed to provide Rs 44.8 crore in four years for infrastructure," the minister added.

Bengaluru, Jul 8: In a setback to the State government, the Karnataka High Court on Wednesday stayed the initial ban and the subsequent restrictions imposed on schools against conducting online classes from pre-primary to Class X.

Prima facie the ban and embargo imposed on online education violate Articles 21 and 21A of the Constitutionon the fundamental right to education, the Court said.

A Division Bench comprising Chief Justice Abhay Shreeniwas Oka and Justice Nataraj Rangaswamy passed the interim order staying the operation of Government Orders issued on June 15 and June 27 respectively.

The Bench passed the interim order on the petitions filed by parents of children and several educational institutions questioning the legality of the ban and the restrictions imposed.

However, the Bench made it clear that this order should not be construed that the schools have right to make online education compulsory and can charge fee for offering online education. Also, the schools should not deprive students, who cannot opt for online education, the lost education when the schools reopen on regular basis.
