Spring Viremia of Carp is a highly infectious viral disease of carp, koi and goldfish. The virus is shed in the feces, urine and gill secretions of infected fish into the water, where it infects other fish by entering through the gills. The virus may be introduced into other tanks and bodies of water by contaminated equipment and clothing. Mortality rates associated with Spring viremia of carp can reach 90 percent depending on the age of the fish, species infected and water temperature. As the name implies, outbreaks of Spring viremia of carp are most common in the spring and fall.
