West Nile was first confirmed in Pennsylvania in 2000 when it was found in a horse, mosquitoes, and birds.
There have been nearly 40,000 cases of West Nile in the United States since then, and 119 deaths, according to the Centers for Disease Control.

There was only been one case of West Nile in a human reported in Pennsylvania in 2015, although many western states have had more positive tests.

According to the CDC, about 1 out of every 5 infected humans will develop a fever and other symptoms from West Nile.

Less than one percent of humans infected develop a fatal neurologic illness, the CDC said.
