Carl Knighton, dead with hives

Carl Knighton, one of the victims, as seen with hives over his body.

The Dorsavirus is a contagious and fatal disease that was spread in Castlefall, a district in Starling City, then to The Glades. The only known symptoms are hives. The disease itself had not been prevalent since the early 1980s, outside of the United States, though in 2007 there was a quarantined outbreak in a women's shelter in Coast City, causing Sheila Knighton to catch the virus and carry it for numerous years.
