Zone # 20B This is to inform you that the Louisiana Animal Disease Diagnostic Lab has confirmed one West Nile Positive Sentinel Chicken in Terrebonne Parish. This Sample was from the location within the Central Bayou Black area. In accordance with the Expanded Transmission Protocol, we are asking for permission to proceed with CDC West Nile procedures. 1) The location described above will be considered to be the epicenter of the problem. 2) Personnel will be assigned to inspect the immediate areas surrounding the epicenters and to continue outward for an approximate five-city block area. The purpose of the search will be to locate vector mosquito (the Southern House Mosquito and/or the Asian Tiger) breeding sites. Positive sites will be addressed with bacterial or other larvicides. 3) Residents in the area will be made aware that there is a heightened potential for encephalitis infection in their neighborhood and that personal protection and yard sanitation is required. This will be done by distributing informative literature within approximately a five-block radius of the epicenters. 4) When it is necessary to enter a property, the resident will be asked to grant permission to allow inspection of the premises for mosquito breeding and to allow inspectors to take action against any mosquitoes located. 5) During the evening hours, truck mounted sprayers will be assigned to spray Zone 20B, in an effort to reduce/maintain the vector populations below the critical level as noted in the RFP 09-MOSQ-11 pages 39 and 40, Expanded Surveillance Protocol. Spraying will be conducted on the evenings of: 06-12-2015 (Friday), 06-13-2015 (Saturday), and 06-14-2015 (Sunday), weather permitting. 6) The efficacy of these operations will be determined through the use of Gravid Traps that are scheduled for operation immediately following the completion of the control activities. The number of mosquitoes collected will serve to quantify the adult population and provide specimens to be re-submitted for testing at Louisiana Animal Disease Diagnostic Lab.
