U.S: Tracking the virus in wastewater is helping respond to the most recent wave of the coronavirus, but a more coordinated national effort is needed, experts sa

 

As the highly contagious Omicron variant pushes national coronavirus case numbers to record highs and sends hospitals across the country into crisis mode, public health officials are eagerly searching for an indication of how long this surge might last.

The clues are emerging from an unlikely source: sewage.

People who contract the coronavirus shed the virus in their stool, and the virus levels in local wastewater provide a strong, independent signal of how much is circulating in a given community.

The sewage data reveal an Omicron wave that is cresting at different times in different places.

Researchers Make Progress Toward High-Performing Water Desalination Membranes

http://www.sci-news.com/othersciences/materials/high-performing-water-desalination-membranes-09209.html

Biological membranes can achieve remarkably high permeabilities while maintaining ideal selectivities by relying on homogeneous internal structures in the form of membrane proteins. In new research, a team of scientists led by Penn State University and the University of Texas at Austin applied such design strategies to desalination polyamide membranes.

Dr. Enrique Gomez, Dr. Manish Kumar and their colleagues from Iowa State University, Penn State University, the University of Texas at Austin, DuPont Water Solutions, and Dow Chemical Co. found that creating a uniform membrane density down to the nanoscale of billionths of a meter is crucial for maximizing the performance of reverse-osmosis, water-filtration membranes.

UB Startup Uses Sunshine to Clean Dirty Water for Disasters, Poor Nations

           

Solar still in water. QIAOQIANG GAN, SUNY BUFFALO

buffalonews.com - by T.J. Pignataro  - October 15, 2017

Distilling water using the sun’s rays . . . a University at Buffalo startup has found a quick way to do it . . . and it could transform how potable water gets to people in developing countries or in areas stricken by natural disasters like earthquakes or hurricanes.

The university’s Sunny Clean Water startup said its method is nearly three times as fast as the industry standard . . . 

. . . The process uses a floating solar still and a specially-engineered carbon-based cloth to capture, desalinate and purify as much as a liter of water every three hours in a prototype developed by UB associate professor of electrical engineering Qiaoqiang Gan, Singer and other university electrical engineering students.

Direct Relief - Medical Aid Shipment to Sierra Leone

Direct Relief - August 18, 2017

Direct Relief is sending 10,000 lbs of medical aid to Sierra Leone in response to the recent floods and mudslides.  Items including antibiotics, wound care and rehydration supplies left Direct Relief's warehouse today. Water purification supplies and oral rehydration salts will also be sent to help communities that have lost access to clean water.

Sierra Leone: 'Water Shortage May Lead to Cholera'

Deputy Minister of Health and Sanitation 1, Madina Rahman, has said that the current water crisis in Freetown and its environs might cause a cholera outbreak and other water borne diseases.

"Because of the areas where people go to fetch water, I am worried that we may experience water borne diseases," she noted.

Madam Rahman was updating newsmen last Thursday at a presser held at the Ministry of Information and Communications, Youyi building in Freetown.

She said the country was challenged by acute water shortage and that she was worried there could be a serious disease outbreak because people collect drinking water from unprotected sources without boiling or filtering.

She said about 1.8 million people die from cholera and other water borne diseases annually around the world, adding that it was a concern for the government.

Pitt, Drexel, and NIH team up to study persistence of Ebola virus in wastewater

EUREKEALERT                                                                                                               Aug. 25, 2015
PITTSBURGH--The historic outbreak of Ebola virus disease in West Africa that began in March 2014 and has killed more than 11,000 people since, has raised new questions about the resilience of the virus and tested scientists' understanding of how to contain it. The latest discovery by a group of microbial risk-assessment and virology researchers suggests that the procedures for disposal of Ebola-contaminated liquid waste might underestimate the virus' ability to survive in wastewater.

Current epidemic response procedures from both the World Health Organization and the Centers for Disease Control and Prevention advise that after a period of days, Ebola-contaminated liquid can be disposed of directly into a sewage system without additional treatment.

However, new data recently published by researchers from the University of Pittsburgh, Drexel University, and the National Institutes of Health indicate that Ebola can survive in detectable concentrations in wastewater for at least a week or longer.
