Summer may be long gone, but cases of West Nile virus are still popping up – making this year's outbreak the worst so far in the U.S. since 2003.
New tallies released today by the Centers for Disease Control and Prevention bring the total case count for the year to 5,054, and the death toll to 228 — more than the past four years combined.
