What is the West Nile Disease?

The West NIle is a mosquito-transmitted virus. This virus can be minor in some cases, but in others it may be life threatening illness due to inflammation of the spinal cord or brain.

Scientific name

The scientific name of the west nile is Flavivirus (genus).

How does the virus attack and spread?

Birds are the main host of the virus. Mosquitoes become infected when they feed on the birds who have WNV, which circulates through the mosquitoes blood. Now the infected mosquitoes bite humans and animals, for a blood meal. The virus is in the saliva glands of the mosquito. When the mosquito is feeding the virus can become injected into the human or animal. Once inside the body the virus will multiply and cause illness.

Common victims

Humans, and animals can become infected with West Nile. In past years horses have been affected greatly from west nile. There was also an outbreak of west nile among humans. Resulting in deaths of both victims.

Where is west nile found?

The symptoms for the severe disease is headache, high fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, and paralysis.

The disease is also called neuroinvasive disease.

Treatment for Disease
