About 240 people in the Dallas area have been infected with the West Nile virus.

Ten of them have died. The Center for Disease Control said half of all U.S. cases of West Nile have been in Texas.

Health experts said if the West Nile virus trend continues, 2012 will be the worst year for the virus in Texas state history.

Abilene hasn't had any confirmed human cases of West Nile so far, but after one mosquito tested positive for the virus many people started thinking about prevention.

"We try not to come outside during the evening when it's the worst, but during the hottest part of the day it's really not that bad," said Abilene resident Jason Williams.

"We have dogs so if the dog dishes or something outside gets filled with water we dump those," said Thomas Troy Allen who also lives in Abilene. 

But people in Abilene are not too shaken up even though Dallas county has resorted to aerial spraying for the first time in 45 years.

"I'm really not that worried about it. I tend to not get bitten as bad if I stay moving. If I stop and sit still that's when it gets bad," said Williams.

The city of Abilene advises everyone to get rid of any standing water in their yard because one teaspoon of water can hatch up to 500 mosquitoes.

Symptoms of West Nile include fever, headache, body aches, sometimes a rash on the trunk of the body and swollen lymph nodes.
