  • Women Carrying Water – Strength and number of women faculty set Rollins Center for Global Safe WASH apart

    Excerpted from Rollins Magazine – Spring 2022 Issue:

    Where are the women?

    Dr. Sheela Sinharoy 17G asked herself that in October 2016 at her first water, sanitation, and hygiene (WASH) conference in Chapel Hill, N.C. She felt out of place, which never happened within her field of nutrition and health sciences.

    At the coffee table between sessions, Sinharoy looked for someone who looked like her. “I personally feel safer going up to a woman, and I realized that I had to actively look for a woman to talk to,” recalls the assistant professor of global health. “I never would have had to do that at a nutrition conference.” And she needed to look no further than the conference presentations to see that women and girls were left out of most WASH research. 

    Her experience reflected the historical disconnect in WASH research: the people doing it don’t look like the biggest stakeholders. WASH research began in engineering, when that field was dominated by men. Their studies and interventions often missed or neglected women’s concerns—and those are significant, given that women and girls worldwide are doing the washing, cleaning, caring for children, and preparing food. Each day worldwide UNICEF estimates women and girls spend 200 million hours collecting water. In some countries, women and girls experience restrictions on where and when they can defecate.

    Rollins is addressing those concerns. Sinharoy is among seven female core faculty researchers at the only academic WASH center headed by a woman. They are teaching and leading research that centers women and gender in solving persistent issues of safe water, sanitation, and hygiene. Many are balancing their careers with raising their own children, deepening their connection to families around the world, including those who struggle to secure safe water and sanitation.

  • Water Scarcity and Gender – Virtual Event

    Assistant professor, Bethany Caruso, PhD, MPH, was  among the speakers at a virtual event hosted by the journal Nature Water as part of the “Nature Water Talks” event series. Caruso will specifically speak to the ways in which water scarcity permeates women’s and girls’  lives. View Here.

  • Improved Research and Practice Related to Women’s and Girls’ Empowerment and WASH Urgently Needed

    A new Rollins-led review article published in PLOS Water is the most comprehensive synthesis to date of current evidence on water and sanitation and women’s and girls’ empowerment. Bethany A. Caruso, PhD, MPH, was lead author on the article, which was entirely Emory authored.

    With women carrying much of the burden for WASH-related activities at a global scale, investigating the ways in which women’s and girls’ empowerment is impacted by WASH programing is critical in developing effective public health initiatives.

    “Effective WASH programming could engage women to understand their needs and support them with the resources and agency to improve their circumstances,” says Caruso. “Yet, this review illuminates how poor water and sanitation conditions have resulted in myriad negative impacts on women, which continue to remain unaddressed. Women risk physical and sexual violence, experience illness and injury, compromise their mental wellbeing, limit hygiene and food and water intake, and suppress sanitation and menstrual hygiene needs because of inadequate WASH.”

  • Emory University researchers awarded NIH grant to conduct COVID-19 surveillance through detection of SARS Coronavirus-2 in wastewater

    A team of Emory researchers is partnering with Ceres Nanosciences on a $3 million project supported by a grant to Ceres from the National Institutes of Health (NIH) to test wastewater for SARS-CoV-2.

    The study will focus on underserved and vulnerable populations around the Atlanta community where the burden of COVID-19 may be under-recognized.

    Using the Nanotrap® technology from Ceres Nanosciences (Ceres), a company based in Virginia that makes products to improve diagnostic testing, the Emory team will capture and concentrate the SARS-CoV-2 virus directly from sewage.

    This allows rapid detection of the virus and can enable researchers to quickly inform municipal and public health authorities of the presence of the virus in specific geographic areas and trends in virus concentration that reflect trends in COVID-19 cases.

    “The collaboration between Ceres and Emory will generate robust evidence to support the CDC’s objective of developing a national wastewater surveillance system to give city, county and state decision makers important temporal and spatial information on COVID-19 cases in underserved communities,” says Christine Moe, PhD, Eugene J. Gangarosa Chair in Safe Water and Sanitation at the Rollins School of Public Health at Emory University.

    As principal investigator, Moe will be responsible for study design and implementation and will head the engagement with public health and community leaders.

    Moe and Pengbo Liu, PhD, also in the Rollins School of Public Health, will co-lead the wastewater detection efforts. This study builds on their previous wastewater surveillance research on typhoid fever in Kolkata, India, COVID-19 in Accra, Ghana, COVID-19 on Emory University campuses, and an ongoing collaboration with the Atlanta Department of Watershed Management.

    “We are excited to be partnering with Emory on this cutting-edge study. The Department of Watershed Management has played a large role in identifying sites, mapping sample locations, and collecting samples that allow for this joint partnership to progress,” stated Commissioner Mikita Browning.

    “Through this testing, we have the opportunity to focus resources on public outreach, such as locations for rapid testing, vaccine availability, and transportation for those in underserved communities within the City of Atlanta.”

    From Emory University, Leda Bassit, PhD, will serve as co-principal investigator and lead for the SARS-CoV-2 infectivity studies in wastewater and fecal specimens from COVID-19 cases.

    The multidisciplinary team includes researchers from Emory’s School of Medicine, including Raymond Schinazi, Anuradha Rao, Steven Bosinger, Nadine Rouphael and Colleen Kraft, as well as researchers from Emory’s Rollins School of Public Health, including Anne Spaulding, Lance Waller and Yuke Wang.

    This project has been funded in part by the NIH Rapid Acceleration of Diagnostics (RADxSM) initiative with federal funds from the National Institute of Biomedical Imaging and Bioengineering, National Institutes of Health, Biomedical Advanced Research and Development Authority, HHS Office of the Assistant Secretary for Preparedness and Response, Department of Health and Human Services, under Contract No. 75N92021C00012.

  • The Gangarosa Family Endows a Chair at the AUB, Faculty Health Sciences

    The Gangarosa family recently made a gift to AUB to establish the Gangarosa Family Endowed Chair for Safe Water and Sanitation. “All of us at AUB are deeply grateful to the Gangarosa family for this extraordinary gift that will support ongoing and critically important efforts at FHS to address issues related to water, sanitation, and hygiene (WASH) in the Global South, focusing especially on the needs of the Arab world,” said President Fadlo Khuri. The Gangarosa Chair at FHS will work closely with Dr. Christine Moe, the Eugene J. Gangarosa Professor of Safe Water and Sanitation and the director of the Center for Global Safe Water, Sanitation, and Hygiene at Emory University. “Gene and Rose Gangarosa have amazing vision, persistence, and generosity. They have planted ‘WASH seeds’ at several academic institutions which will grow and strengthen public health capacity in WASH research, training, and problem-solving for decades. We look forward to building our ties with AUB and FHS to tackle WASH challenges in the Middle East and the Global South,” said Moe. Gangarosa hopes that the Gangarosa Chair at AUB will lead eventually to the establishment of a WASH Center at AUB – and that it and the WASH Center at Emory University will be part of a network of WASH centers around the world helping to make “our global village a better place.

  • Dr Karen Levy says keep drinking Atlanta’s tap water!

    In a recent op-ed published in the Atlanta Journal and Constitution, Dr. Karen Levy weighs in on the recent boil-water advisory in Atlanta, GA

    Opinion: Keep drinking Atlanta’s tap water

    A few days ago, I, along with thousands of other Atlanta residents, was told that my water is not safe to drink. The Atlanta Department of Watershed issued a citywide boil water advisory due to a malfunction in the Hemphill Water Treatment plant.

    Suddenly the rest of the city was joining me in thinking about their access to safe water, which is how I spend my days as an associate professor of environmental health at Emory’s Rollins School of Public Health. Usually my focus is on conditions in the developing world, but this time the concerns were in my backyard.

    The first thing that many people will do in reaction to this event is to go out and buy bottled water, which was a sensible response for the duration of the boil water advisory (although you could also simply boil or chlorinate your tap water to make it safe).

    Unfortunately, after the boil water advisory is lifted, many people will have lost faith in their tap water, and will continue to purchase bottled water indefinitely. This has far-reaching consequences.

    While counterintuitive, and probably not your first thought when we are under a citywide boil water advisory, buying bottled water will in fact reduce our collective access to safe water.

    There are several reasons for this ………read more
