West Nile Virus West Nile Virus picture of a virus isolated in Maroc Jap. Aftereffects of encephalitis may include deafness, epilepsy, and dementia. Ticks with wnv have been found in Asia and Africa. Their role in transmitting the virus was uncertain, but recently West Nile was transmitted to laboratory mice by Orthinodoros moubato tick feeding on infected mice. The virus incubation period in humans is 5-15 days.
Most people fight off the West Nile Fever Virus without getting sick.
For those who do get sick, the fatality rate is not very high, about ten to fifteen percent. By late June, a veterinarian at an animal clinic had examined and treated several birds that appeared to have nervous system disorders, releasing those that survived. The reports of dead birds increased. By mid-August birds were being sent to the NY State Dept. Of Environmental Conservation.
