More details are included in the following news release issued by the Saint Louis County Department of Health Tuesday.

The Saint Louis County Department of Health has recorded its first probable human case of West Nile Virus this year. The victim is a 55-year-old Kirkwood female who has since resumed normal activities after suffering WNV-type symptoms. The county had two confirmed human West Nile Virus case in 2011.

“Even though serious West Nile Virus cases in humans are rare, it is important to minimize our exposure,” said Health Department Director Dr. Dolores J. Gunn. “We can do this by eliminating opportunities for mosquitoes to breed and multiply and by protecting ourselves by using repellants,”

Here are steps residents can take to reduce the opportunities for mosquitoes to flourish:

  • Flexible drainage pipe is commonly used to drain water from downspouts.  A big drawback is that it holds water and breeds mosquitoes if not properly sloped when installed.
  • At least once a week, drain water from garbage cans, buckets, toys, flowerpots, wading pools, pet dishes, and other objects that can collect water. Change water in birdbaths at least once a week.
  • Look for products containing the active ingredient methoprene or Bti (Bacillus thuringiensis israelensis) to place in birdbaths or ponds, to prevent mosquitoes from developing.
  • Keep gutters cleaned out, and repair any tears in door and window screens.
  • Wear long-sleeved shirts, long pants, and light colors outdoors.
  • Spray clothing with repellents containing DEET or picaridin.

The Health Department routinely collects mosquito samples to test and help determine where to focus control efforts.  Vector Control monitors and treats standing water in public areas as part of its preventative larviciding program.
