It has been reported that the symptoms of fatal West Nile virus are found in Grant and Yakima counties.

Though, the health officials said that they haven't discovered any case of human or animal infected with the virus, the necessary precautions have been issued to everyone to save them from the fatal virus.

According to the figures, the state recorded 38 positive cases of the people infected with the virus during 2009.

A spokesperson from the Washington Health department said that after looking at the figures of the past few years, there are very high chances that the virus will spread more than the last year.

This is because every year the people getting infected with the virus are increasing.

Symptoms of the West Nile virus include severe headache, joint pain, muscular pain and fever. Elderly people are more exposed to the virus because of their weak body.

The infected people are at a risk of developing meningitis, encephalitis or skin infection.

The virus spreads more during spring season and early summers. Except the humans, the birds and horses are also at a high risk of getting infected with the virus.

People living in the vicinity have been informed to wear full sleeves clothes and not to reveal their skin, so as to prevent themselves from the mosquito bites. They have also been asked to cover their windows.
