Viral hemorrhagic septicemia virus (VHSV) is a highly contagious viral pathogen that affects various species of fish. It belongs to the family Rhabdoviridae, genus Novirhabdovirus. VHSV is responsible for causing viral hemorrhagic septicemia (VHS), a devastating infectious disease that affects both freshwater and marine fish populations worldwide.
Viral hemorrhagic septicemia virus is known for its ability to cause hemorrhaging in the internal organs and tissues of infected fish, leading to severe damage to vital organs such as the liver, spleen, and kidneys. The virus primarily affects the vascular system, compromising the functionality of blood vessels and causing circulatory problems.
Transmission of VHSV occurs through direct contact between infected and susceptible fish, as well as through waterborne routes. The virus can persist in infected fish, as well as in water, for extended periods, allowing for its spread and survival in aquatic environments.
Clinical signs of VHSV infection include lethargy, pale or darkened skin, swollen abdomen, fin erosion, and bleeding from the eyes, skin, and gills. Mortality rates in infected fish can be high, especially in susceptible species.
Due to its significant impact on fish populations and potential for economic losses in the aquaculture industry, VHSV is considered a significant concern for fisheries and wildlife management authorities. Efforts to control the spread of VHSV involve implementing stringent biosecurity measures, such as preventing the movement of infected fish and disinfection of equipment and facilities to minimize the risk of transmission.
