wastewater surveillance – UofL News Fri, 17 Apr 2026 17:45:05 +0000 en-US hourly 1 Helping hands across the globe /section/science-and-tech/helping-hands-across-the-globe/ Wed, 13 Nov 2024 22:29:19 +0000 /?p=61580 A landlocked country in southeastern Africa, Malawi faces significant health care challenges, which are made worse by difficulty in obtaining medical equipment and supplies.

To help fill the needs, University of Louisville faculty members joined forces with Louisville nonprofit earlier this year to learn the most critical needs, then pack and deliver a 40-foot shipping container with those supplies to health care workers and researchers in Malawi.

The project originated with Rochelle Holm, a UofL associate professor with the who is conducting wastewater-based epidemiology in the city of Blantyre, Malawi, and Bethany Hodge, director of the in the UofL School of Medicine. When Hodge traveled to the country in 2023 to explore learning and service opportunities for UofL medical students in the Distinction in Global Health track, she took note of specific needs in the Malawi hospitals she visited.

“Whenever I am walking through a clinical site overseas or seeing other kinds of work going on, I am mentally taking inventory of all the things the doctors, nurses and staff are saying would facilitate their work,” said Hodge, who also is a board member of SOS, which recovers and redistributes surplus medical supplies that otherwise would go into landfills. “There were enough things on their lists that I knew SOS had in their warehouse that I wanted to connect the two entities once I got home to see if the SOS program could be part of filling the needs.”

Holm is permanently based in Malawi, where her research involves regular sampling of wastewater from two hospitals as well as community pit latrines to monitor infectious disease trends and outbreaks. The work requires supplies that are , specifically consumable items such as pipettes, personal protective equipment and laboratory analysis supplies. Holm also asked her research and hospital collaborators about their most critical needs.

Hodge relayed the hospitals’ and Holm’s needs to SOS, which assembled the items and organized a shipment that included durable medical equipment, surgical and consumable medical supplies for area hospitals, along with the research supplies for Holm’s work.

The materials, valued at $380,077, were packed in the container and departed Louisville in late May. The shipment arrived in Malawi on Sep. 20.

“The supplies we received from SOS are difficult to obtain in country, so this shipment is extremely valuable,” Holm said. “It will allow us to continue testing for pathogens circulating in the community with less concern about running out of materials for our research, as well as assisting the sampling sites with meeting critical supply needs to support health care delivery.”

The Malawi University of Science and Technology, which collaborates with Holm on the wastewater research, and its hospital partners received a portion of the shipment.

“As a university, we really appreciate the donation from SOS, which has come at the right time when the university is strengthening its outreach aspect,” said Petros Chigwechokha, head of Malawi University’s Department of Biological Sciences. “The donation will be extended to the university’s key partners, Queen Elizabeth Central Hospital and Thyolo District Hospital, where they will fill a big gap in equipment and consumables and ultimately strengthen health delivery services.”

Another segment of the shipment went to a heath care facility in southern Malawi supported by Bridge Kids International, a Louisville-based group that works locally and abroad to connect children to their African heritage culture and build relationships between Africans and African Americans.

UofL Envirome wastewater surveillance shows rapid rise of flu virus /section/science-and-tech/uofl-envirome-wastewater-surveillance-shows-rapid-rise-of-flu-virus/ Thu, 09 Nov 2023 17:19:22 +0000 /?p=59598 Flu season has officially arrived. Surveillance by the University of Louisville’s Christina Lee Brown Envirome Institute shows a significant increase in flu virus concentration in Louisville’s wastewater, and the most recent from the Louisville Metro Department of Public Health and Wellness (LMPHW) also show an increase in cases reported by health care providers. Flu season typically occurs between October and May, with peak activity in December and January.

Researchers at UofL’s Envirome Institute, in collaboration with the Department of Public Health and Wellness, have utilized a wastewater-monitoring approach to track the presence and levels of infectious diseases, including the flu and COVID-19, to offer an early-warning system for Louisville.

“Wastewater monitoring involves tracking the presence of pathogens, such as viruses, in sewage or wastewater,” said Ted Smith, associate professor of pharmacology and toxicology and environmental medicine at UofL. “This innovative technique allows researchers to detect the early signs of disease outbreaks in a community, providing valuable insights into the potential spread of illnesses and enabling timely public health responses. Our latest wastewater report shows flu season has officially arrived. If you have not taken action already, now is the time to take steps to protect yourself and your family from getting sick.”

“To reduce the chance of severe symptoms and hospitalization, the most effective and proactive step you can take is to get vaccinated against the flu,” said Kris Bryant, associate medical director at LMPHW, professor of pediatrics at UofL and pediatric infectious diseases specialist at Norton Children’s. “To be protected during this time of spread, it is crucial to receive your flu shot as soon as possible. It’s recommended that everyone 6 months and older get their flu vaccine. The flu vaccine is both safe and highly effective.”

It typically takes about two weeks for immunity to develop after vaccination. According to the Centers for Disease Control and Prevention (CDC), individuals who were vaccinated against the flu last year were 40% to 70% less likely to be hospitalized due to flu-related illness or complications. Vaccination not only protects you but also contributes to the overall community’s well-being by reducing the spread of the virus.

UofL’s Envirome Institute and the Louisville Metro’s Department of Public Health and Wellness are committed to leveraging innovative technologies and research methods to safeguard the health of our community. By monitoring wastewater, we can stay one step ahead of disease outbreaks and better protect the well-being of all residents.
