WACO (August 2, 2012)--The McLennan County Public Health District confirmed one more case of the West Nile Virus in the county Thursday.

That increases the total number of confirmed cases to 12.

The health district says an 80-year-old McLennan County resident died from the virus.

No cases have been reported in Bell County and the Texas Department of State Health Services reports no confirmed cases in other area counties.

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.
