Four Calcasieu mosquito pools tests positive for West Nile Virus

Calcasieu Parish Mosquito Control has received confirmation from the Louisiana Animal Disease Diagnostic Laboratory in Baton Rouge that four of the parish’s mosquito pools — collections of mosquitoes from different areas in the parish — have tested positive for the West Nile Virus.

The West Nile Virus is transmitted by mosquitoes and can cause inflammation of the brain. Most people infected with WNV do not feel sick, but about one in five people who are infected develop a fever and flu-like symptoms. About 1 out of 150 infected people develop a serious — sometimes fatal — illness.

“Most years we see our first positive pools in July. The early hot, dry weather has caused mosquitoes and birds to search for water, bringing them into close proximity and this increases the likelihood of disease transmission,” said Scott Harrington, Calcasieu Parish Mosquito Control manager. “The dry conditions can cause a lower mosquito population but an increase in mosquito-borne virus activity.”

Mosquito Control will be increasing both ground an aerial spraying to combat the problem.

A reminder to all residents to always use mosquito repellent and if possible, wear long sleeves and pants when going outdoors — especially at dawn and at dusk. Also, mosquitoes typically lay their eggs in water, so make sure to dispose of or drain any water-holding items around your home.
