Article Synopsis
- * The study found higher SARS-CoV-2 positivity rates and viral loads in urban samples compared to rural ones, with key factors like population density and humidity affecting the virus's spread.
- * Using a modified SEIPR model, researchers estimated that unreported COVID-19 cases could be significantly higher than confirmed cases, suggesting wastewater surveillance could help authorities manage future outbreaks more effectively.
Article Synopsis
- The study looked at wastewater in Nagpur, India, to find out what viruses were present during the COVID-19 pandemic.
- Researchers found many types of viruses, including chikungunya and rabies, that had never been seen in wastewater before.
- They discovered that SARS-CoV-2 (the virus that causes COVID-19) was common, especially in rural areas, along with other infections like Hepatitis C.
The present study tracked the city-wide dynamics of severe acute respiratory syndrome-corona virus 2 ribonucleic acids (SARS-CoV-2 RNA) in the wastewater from nine different wastewater treatment plants (WWTPs) in Jaipur during the second wave of COVID-19 out-break in India. A total of 164 samples were collected weekly between February 19th and June 8th, 2021. SARS-CoV-2 was detected in 47.

- The study investigates how earthworms and microorganisms work together in vermifiltration technology to effectively treat clinical laboratory wastewater and reduce antibiotic resistant bacteria (ARB).
- Results show that vermifiltration significantly decreases indicators of pollution (BOD and COD) by 78-85%, removes over 99.9% of coliforms and pathogens, and alters the prevalence pattern of ARB.
- Molecular analyses reveal key resistance genes, suggesting that the microbial community and biofilm formation in the system help combat pathogens and modify antibiotic resistance, supporting vermifiltration as a reliable and eco-friendly wastewater treatment method.
The infection with SARS-CoV-2 is reported to be accompanied by the shedding of the virus in fecal samples of infected patients. Earlier reports have suggested that COVID-19 agents can be present in the sewage samples and thus it can be a good indication of the pandemic extent in a community. However, no such studies have been reported in the Indian context.

Bones were evaluated by microcomputed tomography (μCT), bone strength tester, histomorphometry and serum biochemical markers of bone turnover. Drill-hole was made at femur metaphysis and bone regeneration in the hole site was measured by calcein binding and μCT.
