The Louisiana Department of Health reported the first human cases of West Nile virus for this year. These initial cases are listed in this year’s first weekly Arboviral Report and shows six WNV infections, distributed as follows:

  • Three cases of neuroinvasive disease: one case each in DeSoto, St. Tammany and Tangipahoa parishes,
  • Two cases of fever: one each in East Baton Rouge and Ouachita parishes, and
  • One asymptomatic case in East Baton Rouge Parish that was diagnosed because of a blood donation.

Parish President Chester Cedars has been advised by our independent contractor for mosquito control that ONE mosquito pool tested positive for West Nile virus in the Breaux Bridge area.  In response, and for precautionary reasons, our mosquito agent has been instructed to increase spraying immediately.

Even though our Parish has no report of a human case, you should nonetheless enhance your efforts to PROTECT YOURSELF because mosquito control/abatement does not mean “mosquito elimination.”  Our contractor has requested that the Parish advise you as follows:

“1) Residents are encouraged to wear insect repellant [sic], preferably one containing DEET. Always read repellant [sic] labels carefully, especially for younger children. Also, try to wear light colored, long sleeve clothing and socks.

2) Repair or replace broken screens on windows and doors, and avoid using perfumes or colognes.

3) Residents should remove any standing water around their homes or businesses. Clogged rain gutters and pet water bowls can produce thousands of mosquitoes per week and something as small as a coke can or bottle cap can produce a breeding site for mosquitoes. Remember, please remove any standing/stagnant water.

4) Avoiding mosquitoes and their peak activity times of dusk and dawn is highly recommended, but if one must be outside, please wear repellant [sic].

5) Again in 2018, West Nile virus has now been confirmed in Upper St. Martin Parish. Residents in these areas are being informed that there is a heightened potential for encephalitis infection within any of these locations.

6) Personal protection and yard sanitation is recommended and encouraged.

7) During the evening hours ULV Truck mounted sprayers will be assigned to spray with in the Parish of Saint Martin in an effort to reduce/maintain the vector population below critical levels as noted in the CDC Expanded Protocol measures. Spraying will be conducted for three consecutive evenings in the affected areas, weather permitting.

8) The efficacy of these Truck Spraying operations will be determined through the use of Gravid Traps that are scheduled for operation immediately following the completion of the mosquito control activities. The number of mosquitoes collected will serve to quantify the adult population and provide specimens to be submitted for retesting at Louisiana Animal Disease Diagnostic Lab.
