"This first human case of WNV confirmed in our community is a good reminder that we need to take personal protective measures. The best way to protect yourself from mosquito-borne disease is by using an insect repellent when you go outdoors," Dr. Umair A. Shah, Executive Director of HCPHES, said.

West Nile Virus season typically runs from June through October. In 2014, there were 61 human cases of West Nile Virus illness in Harris County (excluding the City of Houston), including one WNV-related death.

Here are some tips:

Mosquito-Proof Your Property
• Don't "feed" the storm drains. Sweep up lawn clippings, leaves and tree limbs.
• Remove/empty containers that can hold water such as tires, flowerpots and toys.
• Change water in birdbaths and pet water bowls every 3 to 5 days.
• Keep rain gutters free of debris.
• Make sure screens are in good condition.

Personal Protection
• When outdoors, use an insect repellent containing the active ingredient DEET, Picaridin, oil of lemon eucalyptus, or IR3535 and apply as directed on the label.
• If possible, wear long-sleeved shirts and long pants from dusk on because this is when the primary mosquito (Culex) that transmits West Nile Virus is most active.

Most people who are infected with West Nile Virus show no or only mild symptoms such as: low grade fever, muscle aches, and headache. More severe signs and symptoms can include: high fever, stiff neck, disorientation, encephalitis, and rarely, death. If you think you have been infected with West Nile Virus, contact your health care provider.
