Bourbon Virus Transmission, New York, USA.

In July 2019, Bourbon virus RNA was detected in an Amblyomma americanum tick removed from a resident of Long Island, New York, USA. Tick infection and white-tailed deer (Odocoileus virginianus) serosurvey results demonstrate active transmission in New York, especially Suffolk County, emphasizing a need for surveillance anywhere A. americanum ticks are reported.

Modeling and Surveillance of Reporting Delays of Mosquitoes and Humans Infected With West Nile Virus and Associations With Accuracy of West Nile Virus Forecasts.

Importance: West Nile virus (WNV) is the leading cause of domestically acquired arboviral disease.

Objective: To develop real-time WNV forecasts of infected mosquitoes and human cases.

Design, Setting, And Participants: Real-time forecasts of WNV in 4 geographically dispersed locations in the United States were generated using a WNV model-inference forecasting system previously validated with retrospective data.

Improved high-throughput method for molecular identification of Culex mosquitoes.

Culex pipiens, Cx. restuans, and Cx. salinarius play important and most likely different roles in transmission of West Nile virus (WNV) in the northeastern United States.
