Symptoms of West Nile

Most humans infected by the West Nile Virus have no symptoms, while a few may have these symptoms:

  • fever
  • headache
  • body aches,
  • lethargy
  • skin rash on the chest, back and arms
  • swollen lymph glands

Those seriously infected, particularly the elderly, display these symptoms:

  • headache
  • high fever
  • stupor
  • coma
  • tremors
  • muscle weakness
  • muscle weakness
  • stiff neck
  • disorientation
  • convulsions
  • paralysis
  • in rare cases death

The after-effects of West Nile virus include mild weakness and memory loss that usually clears up within a few weeks. Recover is nearly always complete but less rapid in adults and children. There is also a low incidence of seizures.

Less than one percent affected become seriously ill and that occurs within three to 15 days after the bite of the infected mosquito.
