(August 15, 2012)—The total number of confirmed cases of West Nile virus in Central Texas rose to 24 Wednesday, most of them in McLennan County.

The Waco-McLennan County Public Health District Wednesday said 21 cases have been confirmed, including one death.

The latest figures from the Bell County Public Health District showed three confirmed cases, including one death.

Elderly and people with compromised immune systems are at a greater risk for severe complications.

Symptoms include fever, severe headaches, confusion, disorientation, and muscle weakness.

To help prevent the virus the Health District recommends eliminating any standing water that may provide a place for mosquitoes to breed and staying inside in the late evening and early morning hours when mosquitoes feed.

Those who plan to be outside should wear long sleeves and long pants and should use a repellent that contains DEET.
