Spring break could compound West Texas measles outbreak

Most Texas schools go on spring break this week, which could be a major issue compounding the ongoing measles outbreak in West Texas, said Jennifer Horney, an epidemiologist at the University of Delaware. The outbreak, which has grown to more than 200 cases and claimed the life of a child last week, is likely to continue to grow as new cases are identified in both surrounding communities as well as other states, Horney said.

Horney, founding director of UD's epidemiology program, can also comment on vaccination of measles, which is one of the most highly contagious infectious diseases.

• Through maintenance of vaccination coverage of greater than 90%, the U.S. was able to gain eradication status in 2000.

• Although there have been sporadic cases, and even outbreaks, since then, worsening vaccine hesitancy has led to vaccination rates in some communities of 80% or lower.

• According to data, of 20 outbreaks involving three or more cases reported in the last five years, 40% were in 2024. With outbreaks currently in at least nine states in the U.S., 2025 looks to be a very bad year for measles infections.

Food safety expert available to discuss emerging health risks

The University of Delaware’s Kalmia Kniel can discuss foodborne parasites and food safety risks, including the ongoing cyclosporiasis outbreak spreading across the United States. Kniel, a professor of microbial food safety, can explain how foodborne parasites spread, why outbreaks (particularly those involving the Cyclospora parasite) can be challenging to investigate and what consumers should know about reducing their risk of illness. She co-authored a study published in December 2025 that examined challenges researchers face in detecting, studying and controlling Cyclospora cayetanensis, including gaps in understanding the parasite and improving prevention strategies. Kniel can also discuss why fresh produce and water are often a focus during investigations and the steps consumers can take to improve food safety. Kniel’s expertise includes: • Foodborne parasites and illness outbreaks • Produce and microbial food safety • Food contamination and prevention • Food safety research Kniel discussed the biology of this specific pathogen in detail at a recent presentation on cyclospora.

Wildfire smoke: Climatologist available to explain air quality and impacts

Wildfire smoke has increasingly affected communities across the United States, including the latest episode in which smoke from Canadian wildfires has moved into the Midwest and Mid-Atlantic regions. The University of Delaware’s Kevin Brinson is available to explain the atmospheric conditions that allow wildfire smoke to travel long distances and affect regional air quality. Brinson, an assistant research professor and Delaware’s state climatologist, can speak to: • How wildfire smoke travels long distances through the atmosphere. • The role of weather patterns, winds and atmospheric conditions in transporting and dispersing smoke. • How wildfire smoke events are monitored and forecast. • How atmospheric and seasonal weather patterns influence smoke transport and regional air quality.
