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.

Udupi district transformed into a sea of saffron and celebration on Friday, November 28, as Prime Minister Narendra Modi’s roadshow swept through the coastal temple town. Thousands of residents lined the streets, turning the event into a vibrant public spectacle filled with cheers, flags, and festive energy.

The procession route—from the helipad to the historic Sri Krishna Math—was decked with buntings, saffron flags, and multilayered security barricades. One of the district’s largest-ever security deployments was put in place for the high-profile visit, with over 3,000 police personnel on duty. The arrangement included ten SPs, 27 DSPs, 49 inspectors, 127 sub-inspectors, 232 assistant sub-inspectors, 1,608 constables, and 39 women staff.

Six platoons of the Karnataka State Reserve Police, six Quick Response Teams, bomb detection units, and dog squads were stationed across Udupi. Enhanced surveillance covered Adi Udupi, Bannanje bus stand, and the Sri Krishna Math parking zone, with combing operations carried out along the roadshow corridor.

At the 800-year-old Sri Krishna Math, preparations reached a ceremonial peak. Paryaya Puttige Math seer Sugunendra Teertha Swamiji said the Prime Minister would take part in the Laksha Kantha Geetha Parayana, a mass chanting of the Bhagavad Gita by one lakh devotees, and inaugurate the new Suvarna Teertha Mantapa.

“He will first offer floral tributes to saint-poet Kanakadasa and then unveil the golden covering over the Kanakana Kindi,” the seer said.

The Prime Minister will also receive a Poorna Kumbha welcome and have darshan of Lord Sri Krishna, Mukhyaprana Devaru, and the Suvarna Paduke. Union Minister Pralhad Joshi, Karnataka Governor Thaawarchand Gehlot, Minister Bairathi Suresh, Dharmadhikari D. Veerendra Heggade, and seers from the Ashta Maths are expected to join the ceremony.

Ahead of his arrival, the Prime Minister posted on X that he felt “honoured” to attend the spiritually significant gathering. “This is a special occasion that brings together people from different sections of society for a recital of the Gita. This Matha has a very special significance in our cultural life,” he wrote, noting the institution’s long-standing legacy rooted in the teachings of Sri Madhvacharya.

Bengaluru: The Vokkaligara Sangha on Thursday issued a stern warning to the Congress, saying the party could face serious electoral repercussions if Deputy Chief Minister D.K. Shivakumar is not appointed as Chief Minister.

The warning follows the public backing of Shivakumar’s chief ministerial ambition by top Vokkaliga pontiff Nirmalanandanatha Swami, who urged the Congress high command to honor his claim.

“The community supported Congress in the 2023 Assembly elections only because Shivakumar had a real chance to become CM. If he is cheated, we’ll teach the party a big lesson,” said newly elected Sangha president L. Srinivas. He added that Vokkaligas would organize protests under the guidance of community leaders.

General Secretary C.G. Gangadhar pointed out that Congress won more seats in the Vokkaliga-dominated Old Mysuru region due to Shivakumar’s influence, adding, “If Congress wants to retain power, Shivakumar should be made the CM.”

Outgoing president Kenchappa Gowda emphasized Shivakumar’s contribution to Congress’ victory. “Our community voted for Congress thinking he would become CM. Siddaramaiah has also served the party well, but Shivakumar should now be given a chance,” he said.

Former general-secretary Konappa Reddy appealed to Sonia and Rahul Gandhi to recognize Shivakumar’s loyalty and service, saying, “Congress is known to keep its promises. We hope it won’t break the promise made to him.”

Bengaluru, Nov 26: Karnataka is taking its first concrete steps towards lifting a three-decade-old ban on student elections in colleges and universities. Deputy Chief Minister D.K. Shivakumar announced Wednesday that the state government will form a small committee to study the reintroduction of campus polls, a practice halted in 1989 following incidents of violence.

Speaking at a 'Constitution Day' event organised by the Karnataka Congress, Mr. Shivakumar underscored the move's aim: nurturing new political leadership from the grassroots.

"Recently, (Leader of the Opposition in Lok Sabha) Rahul Gandhi wrote a letter to me and Chief Minister (Siddaramaiah) asking us to think about restarting student elections," Shivakumar stated. "I'm announcing today that we'll form a small committee and seek a report on this."

Student elections were banned in Karnataka in 1989, largely due to concerns over violence and the infiltration of political party affiliates into campus life. The ban effectively extinguished vibrant student bodies and the pipeline of young leaders they often produced.

Mr. Shivakumar, who also serves as the Karnataka Congress president, said that former student leaders will be consulted to "study the pros and cons" of the re-introduction.

Acknowledging the history of the ban, he added, "There were many criminal activities taking place back then. We’ll see how we can conduct (student) elections by regulating such criminal activities."

The Deputy CM reminisced about his own journey, which began on campus. He recalled his political activism at Sri Jagadguru Renukacharya College leading to his first Assembly ticket in 1985 at the age of 23. "That's how student leadership was at the time. Such leadership has gone today. College elections have stopped," he lamented, adding that for many, college elections were "like a big movement" where leaders were forged.

The move, driven by the Congress high command's push to cultivate young talent, will face scrutiny from academics and university authorities who have, in the past, expressed concern that the return of polls could disrupt the peaceful academic environment and turn campuses into political battlegrounds.
