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.

US and British warplanes have carried out fresh airstrikes on the Yemeni capital Sana'a and other regions, intensifying attacks as Yemeni Armed Forces continue their anti-Israeli operations in support of the Palestinians in the Gaza Strip amid the regime’s genocide.

Yemen’s al-Masirah television network reported that US and British aircraft targeted the premises of the Yemeni Defense Ministry in the the Assafi'yah district of Sana’a early on Tuesday.

Local sources heard loud explosions echoing from the site of the strikes. 

The report, however, did not provide any details regarding potential casualties or damage.

For his part, the Yemeni information minister vehemently denounced the latest US and British airstrikes against Sana’a, stating that the act of aggression “falls within the framework of attempts to diminish the Yemeni nation’s will to support Palestinian people.”

Hashem Sharaf al-Din underscored that enemies are unable to undermine Yemen’s military capabilities, as its government and nation are standing firm in the face of their vicious and terrorist attacks.

This came hours after the spokesman for the Yemeni Armed Forces announced in a statement that the country’s missile units had carried out a military operation against an Israeli military target in Tel Aviv, using a hypersonic Palestine 2 ballistic missile

Brigadier General Yahya Saree noted that the missile strike was in support of the Palestinians in the Gaza Strip, and successfully achieved its desired objectives.

The Yemeni Armed Forces will continue their operations, and will strike all Israeli facilities within the occupied territories, Saree pointed out, adding that such strikes will not stop unless the ongoing aggression on Gaza ends and the siege is completely lifted.

Early on Monday, American and British warplanes conducted a joint airstrike on targets at the Midi district in Yemen’s northern province of Hajjah.

US and British military aircraft also targeted a number of locations in the At Tuhayta district of the strategic western province of Hudaydah. Details on potential human or material losses from the strikes were not quickly disclosed.

Yemenis have declared their open support for Palestine’s struggle against the Israeli occupation since the regime launched a devastating war on Gaza on October 7, 2023, after the territory’s resistance movements carried out Operation Al-Aqsa Flood against the occupying entity.

The Yemeni armed forces have said they will not stop their attacks as long as Israel continues its ground and aerial offensives in Gaza.

So far, Israel has killed at least 45,028 Palestinians, mostly women and children, and injured 106,962 others in Gaza.

In October, the US military unleashed B-2 stealth bombers to bomb Yemen in support of Israel. Since then, attacks against Yemen have continued in a bid to halt the retaliatory attacks by Sana'a.

In a significant milestone, the Dakshina Kannada Zilla Panchayat Higher Primary School in Newpadpu, Harekala, has introduced a bilingual Kannada-English medium this academic year, a move spearheaded by Padma Shri awardee Harekala Hajabba. The school has so far received 13 admissions for its Class 1 bilingual program.

This initiative is part of a broader effort by the state government, which approved 38 schools across the district to launch bilingual mediums. Expressing his delight, Hajabba shared that he had been advocating for a bilingual school for years. "The bilingual medium will greatly benefit students in this region who otherwise rely on private schools. However, we currently face a shortage of classrooms. Construction of two additional classrooms is underway, and once completed, we expect higher admissions," he said.

The school had previously been permitted to introduce LKG and UKG classes in the last academic year. According to the school’s headmistress, Rajeshwari, while the pre-primary sections have seen good enrolment, the bilingual Class 1 faced challenges, securing only 13 students. She attributed this to the late notification of permission, which arrived a month after the academic year began, leading many children to enroll elsewhere.

Rajeshwari remains optimistic about the future. "We expect better admissions next academic year as awareness about bilingual education at this government school grows," she said, adding that the classroom shortage will soon be addressed.

Deputy Director of Public Instruction (DDPI) Venkatesha Subraya Patagara noted that bilingual schools across Dakshina Kannada have generally received a positive response, with some schools enrolling more than 100 students. The effort to offer bilingual education in government schools marks a step forward in providing affordable, quality education to underserved regions.

Ayatollah Seyyed Ali Khamenei, Leader of the Islamic Revolution, has called the Syrian conflict a "joint American and Zionist plot," while attributing a secondary role to a neighboring country in the crisis.

Speaking to a gathering in Tehran on Wednesday, Ayatollah Khamenei emphasized, "There should be no doubt that what happened in Syria was plotted in the command rooms of the United States and Israel. We have evidence for this."

The Leader also pointed to the involvement of a neighboring nation, widely understood to be Turkey, stating, "One of the neighboring countries of Syria also played a role, but the primary planners are the US and the Zionist regime."

Ayatollah Khamenei dismissed fears of a weakened resistance front following the takeover of parts of Syria by militants and Takfiri terrorists. He assured that resistance will emerge stronger despite the adversities. "This is what the resistance is, this is what the resistance front is. The more you push, the stronger it becomes; the more you commit crimes, the more motivated it becomes. The more you fight with them, the more widespread it will be, and I tell you, by the Divine Power, the domain of resistance will cover the entire region more than before."

The Leader rejected analysis suggesting that a weakened resistance front would lead to Iran’s decline. "That ignorant analyst, unaware of the meaning of resistance, imagines that when the resistance becomes weak, Islamic Iran will also become weak, and I say that by God's will and power and with the permission of God Almighty, Iran is strong and powerful and will only grow more powerful," Ayatollah Khamenei declared.

Highlighting the divisions among militant groups operating in Syria, the Leader noted, "Each group has its own agenda and all seek to stake out their own turf."
