10 West Nile Virus Symptoms
Symptom #7: Vision Issues
Serious West Nile virus symptoms may include vision issues, especially acute loss of vision. This happens when swelling within the brain exerts pressure on the optic nerves or affects the optic nerves themselves.
While this loss of vision is usually temporary, in some cases, it can cause permanent damage to the optic and ocular nerves. This can lead to a significant or total loss of vision. West Nile virus may also result in optic neuritis or retinitis, which can cause recurrent pain in one or both eyes.
