With hurricane season in full swing, America is coping with relief efforts for Harvey, Irma, José and more. But UNC researchers and social programs are still focused on Hurricane Matthew and its ecological and societal impacts a year later.
At the UNC Institute of Marine Sciences, Professor Rachel Noble analyzes a bacterial pathogen, Vibrio, and its presence in seafood and water.
After tropical storms and hurricanes, runoff and rainwater circulate Vibrio and raise its presence in the affected environment. Vibrio causes gastrointestinal illness through both ingestion and wound infections, making it very effective and highly transmittable.
Through a 10-year research grant received in 2003 from the National Science Foundation, Noble and her team observed that the highest rates of Vibrio were in early fall, contrary to popular belief of a bacterial peak in summer.
“It’s just hard because one of the difficult parts of our work is that we don’t get a lot of events," Noble said. "So you see one pattern after Hurricane Matthew, but maybe there are differences with the next tropical storm.”
Noble is focused on lowering the public’s risk of Vibrio contracted through seafood and contaminated water. Vibrio has an affinity for oysters, because they are filter feeders and concentrate the bacteria. Oftentimes, public health organizations must first wait for a handful of people to get sick before they know to warn the public about the presence of the bacteria.
