The victim was female, 90-plus years old, and a Williamson County resident. A total of six West Nile Virus (WNV) cases have been reported in Williamson County this year. Two cases were first reported in July. Four additional cases of WNV were reported and confirmed in August.
Two of the six reported cases remain under investigation to determine the scope of the illness. Previously, only five cases of WNV have been reported in Williamson County since 2002.
The more serious forms of the West Nile Virus can result in the onset of meningitis and encephalitis, which are infections that have symptoms including headache, high fever, rash, muscle weakness, stiff neck, disorientation, convulsions, paralysis, and coma. All age groups are vulnerable to WNV.
However, the elderly or people with weakened immune systems face the highest risk of developing a severe or even fatal illness from a WNV infection. WNV symptoms usually begin three to 15 days after being bitten. The risk of getting a WNV related disease typically increases in late July and August as more mosquitoes begin to feed on people instead of birds.
