Residents are urged to take measures to minimize the risk of contracting an arbovirus by applying CDC recommended repellents; avoiding peak biting times in the hours before and after dusk and dawn; wearing long sleeve shirts and pants; and draining any standing water on their property.


The risk level for each region is calculated based on a rubric of factors including: abundance primary vector species, the infection rate, environmental conditions, and the number of human & animal cases. Each region will be assigned an advisory level based on this risk assessment: low/no, slight, moderate, and high.

*Animal Infections are classified as birds and horses.


This map will be updated each Monday as new data is received from LADDL on infected pools of mosquitoes. Infected pools will be included in the risk assessment calculation for a two week period from the time of reporting.
