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 14: JD(S) leader HD Revanna has been released from Parappana Agrahara Jail today, on May 14 after he was granted conditional bail. 

He was granted a conditional bail yesterday by a Bengaluru court in connection with a kidnapping case linked to sexual abuse allegation against him and his son Prajwal.

Revanna was arrested on May 4 by Special Investigative Team (SIT) officials in a kidnapping case registered against him at KR Nagar police station in the city. The case is linked to his son and Hassan MP Prajwal Revanna’s mega sex scam. 

Representing the JD(S) MLA from Holenarsipura, he termed this case a "political conspiracy" against him.

A SIT, constituted by the Karnataka government, is probing the alleged sexual abuse against against HD Revanna and his son Prajwal Revanna.

Prajwal Revanna, the incumbent MP, is seeking another term from Hassan Lok Sabha constituency. The voting for the seat took place on April 26.

Earlier, JD (S) chief HD Kumaraswamy alleged that Karnataka government does not want a fair inquiry.

"They are misusing the office. Nothing is going to happen ultimately. They wanted character assassination of HD Revanna and for that reason, they are using their office," Kumaraswamy told ANI.

Meeting Karnataka Governor Tawara Chanda Gehlot on May 9, a delegation of the Janata Dal (Secular) submitted a memorandum and urged Gehlot to recommend a CBI probe.

Prajwal sill absconding

The JD(S) MP, Prajwal, fled to Germany after Karnataka State Commission for Women Nagalakshmi Chowdhary wrote to Chief Minister Siddaramaiah seeking an investigation into over obscene videos of Prajwal Revanna allegedly sexually abusing several women. He has also skipped summons issued by the SIT to appear before it.

The ‘obscene videos’ involving Prajwal Revanna started making the rounds ahead of the first phase of Lok Sabha elections in Karnataka on April 26, triggering a political slugfest.

A lookout notice against Prajwal Revanna has been issued at all airports in India, along with a Blue Corner notice. A Blue Corner notice issued by Interpol helps countries collect and share information regarding a person's location and their activities as part of a criminal investigation.

Bengaluru: Karnataka Deputy Chief Minister D K Shivakumar and other state ministers on Saturday rubbished allegations about their role in the circulation of pen drives containing explicit videos involving Hassan MP Prajwal Revanna.

BJP leader and advocate G Devaraje Gowda, who is in custody after being arrested in a sexual abuse case and is also facing charges of video leak, on Friday alleged that Shivakumar and four other ministers are behind the circulation of the pen drives and was being fixed in false cases as he did not agree to be part of their plan.

He has even alleged that he was offered Rs 100 crore by Shivakumar to "bring a bad name" to the BJP and Prime Minister Narendra Modi, and to tarnish the image of JD(S) leader H D Kumaraswamy in Prajwal Revanna's obscene video case.

Speaking to reporters here, Shivakumar said, "Better, let him (Gowda) file a case before Lokayukta or any other agency. I think he has some problems mentally. I'm very sorry, the national and state media shouldn't have picked up such baseless allegations. A person who is in jail, how can he make such allegations? All these are baseless. I don't want to comment." 

Asked if he will be filing any defamation case against Gowda, he said, "I don't want to make any comment or speak on a person who is mentally sick. I appeal to his party people to get him a good treatment." Shivakumar also asserted that his government's commitment to get justice for women victims of the sexual abuse case, and expressed confidence about the Special Investigation Team's (SIT) ongoing probe.

While being taken from court in Hassan, Gowda on Friday spoke to media and alleged that Shivakumar is behind pen drive case, and a team of four Ministers -- N Chaluvarayaswamy, Krishna Byre Gowda, Priyank Kharge and another minister -- was formed to handle this, with an intention to bring bad name to BJP, PM Modi and Kumaraswamy.

He said Shivakumar had asked him to say that Kumaraswamy is behind the distribution of pen drives, but as he did not agree to it, he is being fixed in false cases.

Minister Priyank Kharge said Gowda has alleged that three responsible ministers in the state government were part of a team and that there was a conspiracy. "We will discuss whatever legal course, we will take it." 

"Devaraje Gowda might be doing this to defame Shivakumar and Siddaramaiah. If he had a Rs 100 crore offer, he should have told Amit Shah (Union Home Minister) and get it investigated. He could have got CBI, ED, or IT raids done. Why didn't he do it? Claims have been made that he (Gowda) was sent Rs 5 crore as advance at a club, let them get CCTV footage and see who were all there," Kharge said.

While speaking to reporters here, he further said Gowda is a lawyer. When he was deposed before the Judge he should have told about the documents he has and should have presented to the court.

Minister Chaluvarayaswamy said allegations about the role of Shivakumar and a team of ministers being formed to oversee the circulation of pen drives are 'baseless', and he questioned Gowda's morality to make such accusations.

"If Gowda proves that Chaluvarayaswamy, Priyank Kharge and Krishna Byre Gowda had held a meeting on this case and we as a team were given responsibility and we were involved in this case, I will apologise," he said and alleged that Gowda was being used to mislead and deviate from the main case of sexual abuse.

Mangaluru: Dakshina Kannada Zilla Panchayat High School in Harekala, popularly known as Padma Shri awardee Harekala Hajabba’s school, is gearing up to inaugurate its first batch of Pre-University (PU) courses starting June 1. 

The government issued an order to elevate the school established by Padma Shri awardee Harekala Hajabba to the status of a PU College a few months ago.

The School Education and Literacy Department (PU Education) has formally sanctioned the upgrade for the school.

CD Jayanna, the deputy director of PU Education, confirmed that all necessary approvals have been obtained from the government to initiate PU classes.

“Hajabba’s school will kick off PU classes for its inaugural batch on June 1. We have appointed a senior lecturer as the interim principal for the PU college. Presently, the school possesses the essential temporary infrastructure to begin the I PU batch. Plans are underway to enhance the infrastructure for the PU college in the future. Currently, the school boasts adequate classrooms and facilities to commence PU classes,” stated Jayanna.

Harekala Hajabba, an orange vendor, personally erected the school in his native village, New Padpu in Harekala, situated approximately 35 km from Mangaluru. For several years, he has tirelessly petitioned the government for the establishment of a PU college.

Expressing his gratitude, Hajabba mentioned that 19 students who recently completed their SSLC examinations are poised to enroll in the new PU college. He added, “We anticipate enrollment from neighboring villages as well. Both the interim principal and the PU education department have been diligently orchestrating the necessary arrangements to initiate classes.” 

He extended his appreciation to the government, local representatives, and officials for their unwavering support.
