Which statement accurately describes the syndrome Seoul virus can cause in humans?

• A. Hantavirus Pulmonary Syndrome (HPS)
• B. Hemorrhagic Fever with Renal Syndrome (HFRS)
• C. Dengue fever
• D. Rabies

Answer: (B)

Seoul virus is an Old World hantavirus carried by rats, and in humans the disease pattern fits hemorrhagic fever with renal syndrome (HFRS) rather than hantavirus pulmonary syndrome (HPS). Old World hantaviruses like Seoul virus typically cause HFRS, which involves fever, hemorrhagic symptoms, and kidney involvement. HPS, by contrast, is associated with New World hantaviruses and presents mainly as a rapid-onset pulmonary illness with respiratory failure. Since Seoul virus infections align with HFRS, that description best matches the syndrome it can cause. Dengue fever and rabies are caused by completely different pathogens and transmission routes, so they don’t describe Seoul virus infection.
