Viral hemorrhagic septicemia virus (VHSV)

Viral hemorrhagic septicemia virus (VHSV) is a highly contagious virus that infects freshwater and marine fish species. It causes a severe disease characterized by internal bleeding, skin hemorrhages, and high mortality rates, often leading to significant fish population declines. VHSV spreads through water, contaminated equipment, and infected fish, posing risks to both wild fish populations and aquaculture industries. While most affected fish die within days, some survive and shed the virus, perpetuating outbreaks. Monitoring and biosecurity measures are vital to prevent and control VHSV to protect aquatic ecosystems and fish farms.
