On August 27, 2019, Aedes aegypti mosquitoes were identified in a neighborhood located in York, NE, through routine arboviral surveillance. Expanded surveillance using traps and morphologic identification revealed 118 adult Ae. aegypti throughout the adjacent neighborhood, including identification from larval sampling. Our findings describe the first recorded Ae. aegypti introduction in Nebraska and provide evidence of a breeding mosquito population, which suggests suitable habitat and the risk of potential establishment, raising concerns about prevention of arboviral diseases in Nebraska.
