Abstract

In 2012, Texas has reported the highest number of West Nile virus (WNV) cases in the United States to the Centers for Disease Control and Prevention. In this report, we conducted a retrospective chart review of 57 patients with WNV disease and analyzed the clinical features of these patients. Our results revealed that 25 (44%) patients were diagnosed with West Nile fever and 32 (56%) with West Nile neuroinvasive disease (WNND). The median age for patients with WNND was 54.5 years, and those with encephalitis were more likely to be >60 years old. Pre-existing conditions such as hypertension and diabetes were more frequent in patients with WNND. Testing both serum and cerebrospinal fluid (CSF) for antibodies diagnosed more cases of WNND than just testing serum or CSF alone. The increasing number of WNV cases during this epidemic highlights the need to increase efforts to control mosquito populations and educate the general public.
