The number of fatalities and missing persons continue to mount after a storm caused massive flooding in the town of Derna, located in the northeast region of Libya.


While search and rescue will remain the most urgent priority in the near term, addressing acute health needs will be a major factor in the wake of this disaster, said Jennifer Horney, founder and director of the epidemiology program at the University of Delaware.


  • The collapse of two dams are likely to cause long-term water borne diseases of all types.
  • With little existing health infrastructure in the area, treating and managing health will be extremely difficult.
  • Safe food and water will be scarce.
  • There is a strong possibility of infectious disease outbreaks and the spread of communicable disease.


Other experts from UD's Disaster Research Center who can comment on the flooding in Libya:

  • Tricia Wachtendorf: Disaster relief and donations, and alignment post-disaster – i.e., making sure donations that aren't needed don't flood the supply chain. Wachtendorf can also discuss evacuation decision-making, volunteer efforts, disaster response and coordination.
  • Sarah DeYoung: Dealing with unsolicited infant formula donations, and infant and maternal health. Can also discuss pets in emergencies, infant feeding in disasters and decision-making in evacuation.

New survey shows lack of public trust in Musk, DOGE

New data from the Center for Political Communication (CPC) at the University of Delaware shows many Americans have little trust in either Elon Musk or the Department of Government Efficiency (DOGE). In a nationally-representative sample of 1,600 adult Americans surveyed by YouGov between February 27 and March 5, 2025, CPC researchers asked how much trust respondents had in various people and institutions, including Elon Musk, the Department of Government Efficiency, and President Trump. Among the key findings: • 25% of Americans report having “a lot” or “a great deal” of trust in Elon Musk 26% report having “a lot” or “a great deal” of trust in Musk’s Department of Government Efficiency (DOGE). • 33% report having “a lot” or “a great deal” of trust in President Donald Trump. • About half of Republicans report “a lot” or “a great deal” of trust in either (compared to 70% of Republicans who report “a lot” or “a great deal” of trust in President Trump). • Among independent voters, only 11% report “a lot” or “a great deal” of trust in Musk and 13% in DOGE. “As constituents in Republican districts learn about and voice concerns about DOGE’s cuts to Veteran’s Affairs, The National Institutes of Health, National Parks, and the Federal Aviation Administration, it will be interesting to see how public trust in Musk and DOGE may be affected,” said Dr. Dannagal Young, Director of the Center for Political Communication and one of the authors of the survey. “Understanding public sentiment about these unique government entities is essential to help ensure that elected officials are responsive to voter concerns."

Understanding waterfowl movement and bird flu

Scores of waterfowl are currently on the move, and experts are worried they could further spread highly pathogenic avian influenza, commonly known as bird flu. But these flocks, which can number in the thousands and include Canada geese and snow geese, are of most concern around poultry houses, said University of Delaware’s Christopher Williams. The risk to humans and dogs getting bird flu from geese who inhabit their neighborhoods remains low, Williams said. Williams, a professor wildlife ecology in UD’s College of Agriculture and Natural Resources, explained why this is happening: • Smaller ducks such as blue-winged teal, larger ducks such as mallards, and larger geese like Canada geese and snow geese are heading north to their breeding grounds. • Waterfowl are a primary reservoir for avian influenza viruses, meaning they can harbor bird flu strains viruses, spread them, and in some cases show no signs of disease. They can shed the virus through their saliva, naval secretions, and feces. • Waterfowl serve as the primary vector of avian influenza to the U.S. poultry industry which has affected more than 8 million commercial and backyard chickens and turkeys that have been culled to keep the virus from spreading. “While we are worried about these flocks congregating near poultry houses, the risk of humans getting bird flu from waterfowl remains low,” Williams said. “Further, walking dogs around areas with geese flocks should pose little threat to dogs’ health as avian influenza is very rare in dogs.” Nevertheless, Williams cautions people and dogs to avoid touching sick birds or dead birds. A large segment of the Canada geese population are not migratory, Williams said. They will stick around the Mid-Atlantic year-round and tend to congregate and breed near grocery store parking lots, golf courses and neighborhoods. “Those birds are being drawn to needing two things. No. 1 is they need water including any natural pond or water containment area,” Williams said. “And all the geese species are herbivores, so No. 2 they eat grass. There are places that have both water and grass that will provide ideal nesting habitat for the geese and their chicks.” Reporters can connect with Williams by visiting his profile and clicking on the “contact” button.
