Outbreaks of dermatologic diseases such as staphylococcal infections, tinea corporis, and arthropod bites occur frequently after hurricanes and flooding. In this retrospective cohort study, Noe et al determined the extent and scope of an outbreak of skin eruptions that affected civilian construction workers living and working on a New Orleans military base after hurricanes Katrina and Rita made landfall. Four clinical entities were identified. Most common was papular urticaria, followed by bacterial folliculitis, fiberglass dermatitis, and brachioradial photodermatitis. People working and living in posthurricane environments may be at increased risk of arthropod exposure, and the authors offer strategies for avoiding dermatologic diseases.
