  • West Nile Virus (WNV), belongs to the Flavivirus family, is considered an endemic disease in many states including Florida.
  • In the last decade, the virus has been prominently reported in the Southern and Midwest States.
  • The disease is most prevalent during the summer to fall month periods due to elevated temperatures leading to enhanced vector transmission.
  • WNV is acquired via the bite of an infected mosquito particularly the Culex species, and is considered as the vector for the disease.
  • Equines and humans are incidental hosts of WNV and disease transmission from these sources are rare. There are various human risk factors that are associated with WNV.
  • Disease prevalence is reported to be equal among the sexes but peak incidence and mortality rates are seen among those who are 50 years of age and older, with a reported increase of encephalitis or meningitis variants of the disease.
  • Comorbidities such as diabetes, hypertension and other chronic illnesses have not been linked to WNV prevalence and disease outcomes.
