Jerusalem, Aug 25: Wastewater containing coronaviruses, such as the one behind the Covid-19 pandemic, may be a potential threat, according to a new review of studies that calls for additional filtration steps in sewage treatment plants to successfully remove viruses.

The research, published in the journal Nature Sustainability, by an international collaboration of 35 researchers, assessed recent studies on coronaviruses in wastewater.

According to the review research, conventional wastewater treatment provides only partial removal of coronaviruses, with safe disposal or reuse depending on the effectiveness of final disinfection.

"There is ample reason to be concerned about how long coronaviruses survive in wastewater and how it impacts natural water sources," said study lead author Edo Bar-Zeev from the Ben-Gurion University of the Negev (BGU) in Israel.

"Can wastewater contain enough coronaviruses to infect people? The simple truth is that we do not know enough and that needs to be rectified as soon as possible," Bar-Zeev said.

According to the scientists, sewage leaking into natural watercourses might lead to infection with the novel coronavirus SARS-CoV-2 via airborne spray.

They said treated wastewater used to fill recreational water facilities, like lakes and rivers, could also become sources of contagion, adding that fruits and vegetables irrigated with this water may also be an indirect infection route.

The scientists recommended immediate, new research to determine the level of potential infection, if any, and how long coronaviruses last in various bodies of water and spray.

"Wastewater treatment plants need to upgrade their treatment protocols and in the near future also advance toward tertiary treatment through micro- and ultra-filtration membranes, which successfully remove viruses," the scientists noted.

They added that wastewater can also be used to monitor or track Covid-19 outbreaks.

Using a new methodology, the researchers recently detected and traced the presence of the novel coronavirus, and calculated its concentration to pinpoint emerging Covid-19 hotspots.

Bengaluru, May 5: In a major development, the Special Investigation Team (SIT) probing the sex video scandal involving JD-S MP Prajwal Revann on Saturday arrested his father and JD-S MLA H.D. Revanna following the rejection of his anticipatory bail plea in a victim kidnapping case by the People’s Representative Court in Bengaluru.

H.D. Revanna was taken into custody from the residence of his father and former Prime Minister H.D. Deve Gowda in Bengaluru’s Padmanabhanagar locality.

First, he was taken to the SIT office on the premises of the Criminal Investigation Department (CID). After preliminary questioning, the former JD-S minister was taken to the Bowring Hospital for a medical check-up.

Sources said he will be produced before the magistrate at the latter's residence later.

Commenting on the development, Chief Minister Siddaramaiah told mediapersons that he won’t interfere in the matter.

“Action should be initiated as per the law,” he said.

Deputy Chief Minister D.K. Shivakumar said, “We will not interfere in anything related to this matter. Let them get protection from the court under the law."

Shivakumar also said that let the proceedings follow the manner suggested by former CM H.D. Kumaraswamy.

Quoting a Kannada proverb, Kumaraswamy had said that those who commit crime must be punished.

The SIT officers reached the former PM’s residence soon after the court turned down his anticipatory bail plea in a case related to the kidnapping of a woman who was allegedly sexually assaulted by his son Prajwal Revanna, the sources said.

Earlier on Saturday, the SIT traced the kidnapped woman to the farmhouse of Rajashekar, the personal assistant (PA) to H.D. Revanna, at Kalenahalli village in Mysuru district.

In the court, Special Public Prosecutor B.N. Jagadish submitted that the case is about saving the life of a poor woman.

Jagadish argued that H.D. Revanna did not turn up before the authorities even after being served three notices.

Senior counsel Muthy D. Naik, appearing for H.D. Revanna, argued that the only allegation against his client is a statement that he had called the victim to his residence.

Barring this, there is nothing to prove the role of H.D. Revanna in this case, he argued, adding that the statement was made by an accused in the case, with whom his client has no connections.

He also claimed that the SIT has deliberately added IPC Section 364A, which attracts life imprisonment and capital punishment, to ensure that his client’s bail plea is rejected.

The other IPC Sections invoked in the case — 363 and 365 — attract imprisonment of less than seven years. Therefore, to prove the innocence of H.D. Revanna, he should be granted bail, Naik submitted.

Meanwhile, the woman, who had gone missing on April 29, was found locked up in the farmhouse when the SIT officers reached there following a tip-off.

Sources said Rajashekar is absconding ever since the SIT traced the missing woman to his farmhouse.

The woman is being brought to Bengaluru where her statement will be recorded.

On Friday, Karnataka Police registered an FIR against H.D. Revanna in connection with the kidnapping of the woman, believed to be one of the victims of the sex video scandal involving his son Prajwal Revanna.

The woman’s son had registered a kidnap case naming H.D. Revanna as the prime accused in the case.

His relative Satish Babu was named as the second accused in the FIR, whom the police arrested from Mysuru district on Friday.

The woman’s son alleged that his mother went missing after the surfacing of a purported sex video in which Prajwal Revanna could be seen sexually assaulting her.

He also alleged that his mother was locked up in an undisclosed location, as he pleaded with the police to initiate legal action against H.D. Revanna and Satish Babu.

Prajwal Revanna, the sitting JD-S MP from Hassan, has reportedly fled from the country.

Canadian Police said they have arrested three Indians they suspect were part of the alleged hit squad that had killed Hardeep Singh Nijjar, a Sikh separatist leader involved with the Khalistan movement, which calls for an independent Sikh state.

Nijjar's killing had become the epicentre of a diplomatic row between India and Canada last year after Prime Minister Justin Trudeau alleged the role of "Indian agents" in the murder. India had rejected the charge as "absurd" and "motivated".

The three arrested Indians - Karan Brar, 22, Kamalpreet Singh, 22, Karanpreet Singh, 28 - were living as non-permanent residents in Alberta for three to five years, said Superintendent Mandeep Mooker, who leads the Integrated Homicide Investigation Team. The police have also released their photos.

They have been charged with first-degree murder and conspiracy to commit murder, showed court documents.

Police said that none of the suspects were known to them earlier and they were investigating their possible ties to the Indian government.

The murder remains "very much under active investigation," Royal Canadian Mounted Police (RCMP) Assistant Commissioner David Teboul told a press conference on Friday.

"There are separate and distinct investigations ongoing into these matters, certainly not limited to the involvement of the people arrested today, and these efforts include investigating connections to the government of India," CTV News quoted him as saying.

Nijjar, a Canadian citizen who was wanted in India on various terror charges, was shot dead outside a gurdwara in Surrey on June 18, 2023. Trudeau's charge against India sparked a massive row later that year with both countries expelling diplomats of the other country.

A fresh row erupted earlier this week after separatist slogans on 'Khalistan' were raised at an event addressed by Trudeau, prompting New Delhi to summon their Deputy High Commissioner and lodge a strong protest.

On the sidelines of the event, Trudeau told reporters that Nijjar's killing had created a "problem" that he could not have ignored.

India rejected his comment and said it once again showed Canada provides political space given to separatism, extremism, and violence. "This not only impacts India-Canada relations but also encourages a climate of violence and criminality in Canada to the detriment of its own citizens," foreign ministry spokesperson Randhir Jaiswal said.

AstraZeneca said on Tuesday it had initiated the worldwide withdrawal of its COVID-19 vaccine due to a "surplus of available updated vaccines" since the pandemic.

The company also said it would proceed to withdraw the vaccine Vaxzevria's marketing authorizations within Europe.

"As multiple, variant Covid-19 vaccines have since been developed there is a surplus of available updated vaccines," the company said, adding that this had led to a decline in demand for Vaxzevria, which is no longer being manufactured or supplied.

According to media reports, the Anglo-Swedish drugmaker has previously admitted in court documents that the vaccine causes side-effects such as blood clots and low blood platelet counts.

The firm's application to withdraw the vaccine was made on March 5 and came into effect on May 7, according to the Telegraph, which first reported the development.

London-listed AstraZeneca began moving into respiratory syncytial virus vaccines and obesity drugs through several deals last year after a slowdown in growth as COVID-19 medicine sales declined.
