Here's another reason to break out the bugspray.

Federal health officials are calling it the worst year ever for West Nile Virus.

A nationwide outbreak of the mosquito- borne illness includes 700 confirmed cases to date; 26 people have died.

In Dallas, where more than a dozen people have died, health officials have declared a state of emergency.

The mayor has authorized the first aerial spraying of insecticide in the city since 1966 to halt the spread of the killer virus.

A reminder to avoid mosquitos as much as possible- don't go out at dawn or dusk, use insect repellent, cover your exposed skin, and get rid of any standing water around your property.
